XanbusTM Network Communications Protocol The XW Pro uses XanbusTM, a network communications protocol developed by Schneider to communicate with other Xanbus-enabled devices. You can configure and monitor the XW Pro and other Xanbus-enabled devices in the system using the Conext Gateway (part number 865-0329). 20 This document is intended for use by qualified personnel 990-91402B Introduction XW Pro Owner's Guide Available XW Pro Accessories Accessory XW Pro Power Distribution Panel Part Number 865-1015-01 XW Pro Power Distribution Panel (Without AC Breakers) 865-1014-01 XW Pro Conduit Box 865-1025-01 Conext Gateway 865-0329 Conext Configuration Tool 865-1155-01 Conext AGS Automatic Generator Start 865-1060-01 Conext MPPT solar charge controller MPPT 60 150 865-1030-1 Conext MPPT solar charge controller MPPT 80 600 865-1032 Conext Battery Monitor 865-1080-01 Conext Response (dongle for DRM feature) 865-1170 Regulatory Certification See Mechanical and Regulatory Specifications on page 138 990-91402B This document is intended for use by qualified personnel 21 XW Pro Owner's Guide Introduction Operation Bidirectional Theory of Operation NOTICE EQUIPMENT DAMAGE n The Automatic Transfer Relays are rated at 60 A. n Loads connected at AC OUT must not exceed the inverter's overload ratings or the 60 A limit, whichever is lower. Unless an external contactor or external transfer switch is used, the 60 A limit also applies to loads connected to the AC OUT bus of multiple inverters connected in parallel. Failure to follow these instructions can result in equipment damage. The XW Pro is a grid forming device consisting of a bidirectional inverter/charger. It is capable of inverting DC power into AC power and controlling the voltage and frequency of its inverter output. It will power external loads attached to AC OUT, see Figure 4 on page 23. The XW Pro is also capable of charging external batteries by converting AC power into DC power, see Figure 5 on page 23. The XW Pro accepts AC power through connection AC2 for charging batteries, usually from a generator, see Figure 6 on page 24. The XW Pro will convert externally sourced DC power into AC power for export to the utility grid attached to its AC1 connection, see Figure 7 on page 24. The XW Pro has internal automatic transfer switches (K1, K2), rated at 60 A, which allow either AC1 or AC2 to be connected to the inverter input, but not both at the same time, see Figure 3 on page 23. This allows shared AC energy during charging or to directly passthrough from AC1, or AC2, to AC Out. Through firmware control over power conversion and the management of K1 and K2, XW Pro can facilitate advanced interaction with the utility grid to optimize the utilization of renewable and non-renewable energy sources. Because the XW Pro is a device capable of forming an AC grid signal (AC voltage and frequency) it is also ideal for use off-grid. The red arrows in the diagrams below represent the direction of power flow in the respective modes of operation. These modes and other special functions will be explained throughout this manual. 22 This document is intended for use by qualified personnel 990-91402B Introduction XW Pro Owner's Guide Figure 3 Connection Points and Major Power Conversion Components of XW Pro AC1 K1 AC2 K2 ACOUT AC Interface Board AC Transformer Bidirectional AC/DC power block Figure 4 Inverting of DC to AC Connected to AC OUT Figure 5 Charging External Batteries and Supplying AC Out with AC Passthrough from AC1 Grid 990-91402B This document is intended for use by qualified personnel 23 XW Pro Owner's Guide Introduction Figure 6 Charging External Batteries and Supplying AC Out with AC Passthrough from AC2 Generator Figure 7 Converting Excess Available DC power for Export to Utility Grid (AC1) and AC Out Figure 8 AC Passthrough 24 This document is intended for use by qualified personnel 990-91402B Introduction XW Pro Owner's Guide Surge Performance Unlike many other inverters, the XW Pro helps stop voltage from sagging dramatically during surge conditions. The XW Pro handles surges of over twice its rated output power with only a minimal drop in output voltage for limited periods of time. Islanding Protection Islanding protection is an essential safety feature that helps reduce harm to those working on the utility grid from a distributed energy source such as the XW Pro. Islanding protection also helps to prevent loads connected to the XW Pro from being damaged by a fluctuating utility grid input. The XW Pro uses proprietary positive feedback control to achieve anti-islanding operation while maintaining low total harmonic distortion at the grid connection. Default software settings are programmed into each XW Pro at the factory so that they comply with applicable safety regulations (such as IEC/EN 62116 (for IEC, EU and Australia regions)). In some instances it may be desirable from both a utility and a customer point of view to adjust the default anti-islanding settings. For example, the XW Pro may experience "nuisance trips" if the grid is weak and the voltage falls outside the allowable range specified by regulations. It may be difficult for a utility to adjust the grid to stop this problem. With permission from the utility, the factory settings may be changed to allow the XW Pro to operate over a wider grid voltage range. These settings must only be changed by qualified service personnel using either Conext Gateway or a special software application (XW Pro Configuration Tool, Order # 865-1155-01) provided by the manufacturer. While exporting energy, the XW Pro continuously monitors the utility grid voltage and frequency. If the grid voltage or frequency move beyond the XW Pro default ranges (for example, during a power surge or outage) the XW Pro stops exporting energy through AC1 and disconnects from the utility. If disconnected due to a grid voltage disturbance, one minute is the non-adjustable minimum reconnect time during which the XW Pro does not export energy through AC1 to the grid. The Event LED on the XW Pro information panel will indicate a utility fault. No fault code appears on the three-character display because the fault is with the utility grid, not with the XW Pro. In addition to the information panel, the Conext Gateway web application indicates any utility faults with details present under all affected instances of XW Pro. The faults cannot be manually cleared. Utility faults will clear automatically when the utility grid voltage and frequency return to within the ranges programmed into the XW Pro. If grid support is enabled and the utility voltage and frequency come back within tolerance, the XW Pro information panel displays a countdown timer for one minute until the XW Pro can start interacting with the grid again. 990-91402B This document is intended for use by qualified personnel 25 XW Pro Owner's Guide AC Coupling Introduction Off-grid AC Coupled system architecture is often used to create a stand-alone grid. Commonly this means that PV inverters are connected to the output of a battery-based inverter/charger putting both on the same AC bus along with the AC loads. In this scenario, the battery powered inverter charger provides the necessary frequency and voltage to enable the PV inverter to produce power. This type of system must be able to maintain power generation in balance with power consumption at all times. If there is more power being generated than can be consumed by the loads, power will flow to the inverter/charger and be converted to DC power which flows into the battery. Once the battery reaches capacity, power generation by the PV inverter must be curtailed to maintain the balance between generation and consumption. As the battery bank reaches capacity, XW Pro curtails PV inverter generation by raising the AC line frequency causing compatible PV inverters to reduce their power output in an orderly manner. This is called Active Frequency Shift Power Curtailment. In some compliance regions, when the grid returns from an outage, XW Pro will cause any AC coupled PV inverter to transition offline via the same mechanism prior to grid reconnection. During a grid outage even a home with a grid-tie PV inverter system will be without power because PV inverters cannot produce power without the presence of a reference voltage and frequency. To enable the PV inverter to provide power during a grid outage the XW Pro is retrofitted in front of the PV inverter. The PV inverter is rewired from the grid connection to a critical load (sub) panel and is AC Coupled to the XW Pro AC Output port. When the grid is present, PV inverter power feeds the loads and any excess is exported by XW Pro to the grid using AC1 (where permitted by the local utility). During a grid outage, XW Pro anti-islanding protection helps to prevents power from being exported to grid on AC1. XW Pro then uses Active Frequency Shift Power Curtailment to reduce the power output of compatible PV inverters, maintaining the balance of generation and consumption. Consult the manufacturer's specifications to determine if your PV inverter is compatible with Active Frequency Shift Power Curtailment. XW Pro AC coupling function is enabled by default (Advanced Features Menu). NOTICE AC COUPLED PV INVERTER COMPATIBILITY AC power generated by AC coupling PV inverters with XW Pro must be consumed by AC loads or used to charge batteries. As an alternative, the excess power produced from a PV inverter can be routed to dump loads. Do not AC couple PV inverters with the XW Pro that are unable to reduce, derate or cease the excess PV inverter power in response to the changes in AC line frequency controlled by the XW Pro. Consult the manufacturer's specifications of your PV inverter and confirm compatibility. Failure to follow these instructions can result in equipment damage. The AC coupling advanced setting should remain enabled except in cases when the DC voltage level is allowed to have large variations and the line frequency needs to remain constant. 26 This document is intended for use by qualified personnel 990-91402B Introduction XW Pro Owner's Guide Further details about AC Coupling can be found in the document AC Coupling of Inverters Solutions Guide (976-0240-01-01) available at http://solar.schneider- electric.com. Multi-unit Operation Important: An external transfer switch may be required to protect the internal relays from the combined loads of the system. For more information, see the XW Pro Multi-unit Design Guide (990-91373). Up to three XW Pro units can be installed together in a split phase configuration with the XW Pro PDP (Power Distribution Panel). The PDP is an ideal optional companion for managing AC connections and integrating a battery bank and other DC connections. Multiple XW Pro units and other Xanbus devices with common connections to battery banks, PV arrays, the utility grid or a generator require programming during commissioning to enable correct operation. Inverting For multiple units, the master XW Pro synchronizes operation of other connected units using the same Xanbus network. When AC loads are present, all units produce power. Refer to the XW Pro Multi-unit Design Guide (990-91373) for total system surge ratings. Parallel Charging Multiple XW Pro units on the same Xanbus network synchronize their charging stages to help provide efficient charging of the battery bank. When a single unit transitions from bulk to absorption, so do all other units. In absorption, all units must complete the absorption stage before any of them transition to the next stage. Note that units stop sharing charge current just before completing the bulk stage and only share charging load during the bulk stage. Each XW Pro unit provides a maximum charging current set by the Max Charge Rate setting. The maximum current may be decreased, subject to the internal operating temperature. When one or more Conext Solar Charge Controllers are installed and operating in the system, XW Pro units synchronize only their bulk charging stage with the charge controllers. Note: Equalization is device specific. Only the device(s) on which equalization was initiated will perform the equalization. Other devices will stay in float or no-float depending on their settings. AC Transfer Multiple XW Pro units monitor each other to determine the quality of AC input. If AC input is deemed to be bad by any of the paralleled units, no transfer to AC Out occurs and the AC LED continues to flash on each unit's information panel until the AC is qualified by all. If the system was in passthrough and AC fails on any unit, all units transfer to invert simultaneously. 990-91402B This document is intended for use by qualified personnel 27 XW Pro Owner's Guide Introduction Faults When the XW Pro detects a fault condition, the fault is displayed on the XW Pro. The XW Pro also turns on the Event LED on the XW Pro and inverter information panel. A fault affects the operation of the unit. See "Fault Types" on page 125 for an explanation of the different fault types. When a single XW Pro slave unit in a multi-unit system has a fault, only the affected device shuts down. When a master unit has an invert mode fault that causes it to stop inverting, it is considered a system-wide fault and all units shut down. Invert mode faults on slave units only shut down the affected slave unit. All units shut down when there is a battery-related fault such as battery over-temperature or over-voltage. Independent Operation of Features Each XW Pro grid-interactive feature (e.g. enhanced grid support, grid sell, load shave and generator support) operates independently. This enables XW Pro units in a multi-unit system to be configured to perform multiple functions independently and allows greater flexibility in operating the entire system. Auxiliary Output Each XW Pro has one programmable 12 V, 0.25 A auxiliary output that is able to run a small fan or operate an external relay to perform other functions. Examples include remotely starting a two-wire start generator in cases where the Xanbus-enabled XW Pro AGS is not used, disconnecting external non-critical loads, or turning on a diversion load for battery voltage regulation. See "Auxiliary Output Settings" on page 79 for programing parameters. Transfer Relays The built-in transfer relays, designated K1 and K2, are each is rated for 60 amps. Connected loads must not draw currents exceeding this.When an external AC source is detected and qualified on either of the AC1 or AC2 inputs, the relay transfers loads from the XW Pro to the external power source, and then activates the battery charger. The XW Pro design does not allow the K1 and K2 relays to close simultaneously. This design helps stop the generator input (AC2) from back feeding to the utility grid (AC1). Multi-unit systems of three or more require the use of an external AC contactor to manage the AC bus. 28 This document is intended for use by qualified personnel 990-91402B Introduction XW Pro Owner's Guide Monitoring the XW Pro Operation of the XW Pro can be monitored using the factory-installed inverter information panel or the optional Conext Gateway.

Symbol LED On AC input is present and qualified. The XW Pro is ready to charge batteries, pass AC through to the loads, or interact with the grid. LED Flashing AC input is present and is being qualified. LED Off The XW Pro is not connected to the grid. AC input is not present, or AC input is present but not within qualifying range. Gen (AC2) The green Gen (AC2) LED indicates the presence and status of a generator or other auxiliary AC source on the AC2 input. Symbol LED On LED Flashing The AC source is present and AC input is qualified. The XW Pro is ready to charge batteries and pass power through to the loads. AC input is present and is being qualified. LED Off AC input is not present, or AC input is present but not within qualifying range. When one AC input LED is on and the other AC input LED is flashing, AC input is present on both AC1 and AC2. However, the XW Pro can qualify and receive AC input from only one source at a time. The qualified source is represented by the steadily lit LED. When two sources of AC input are present, the XW Pro uses the source selected under AC Priority in the AC Settings menu. Monitoring XW Pro Status The Green kW LED indicates the XW Pro is inverting DC input to AC output. When this LED is on or flashing, the display screen shows XW Pro output power in kilowatts. Symbol LED On LED Flashing The XW Pro is inverting and generating an AC output. Display screen shows output power in kW. The XW Pro is in Grid Support mode. Display screen shows output power in kW. LED Off The XW Pro is not inverting. 990-91402B This document is intended for use by qualified personnel 33 XW Pro Owner's Guide Monitoring Operation Monitoring Charger Status The green LED labelled "A" indicates the XW Pro is charging the battery bank. When this LED is on, the numeric display screen shows battery charging current in amps. Symbol LED On LED Flashing LED Off The XW Pro is AC coupled The XW Pro is not charging the battery charging is bank. The numeric occurringa. in charge mode. display screen shows May flash in AC battery charging coupled mode current in amps. where reverse current greater than 3 A is present. Multiple units are connected in parallel under no load. When a charge cycle ends or charging is manually disabled, the XW Pro does not leave charge mode immediately, and the charging LED remains on for 60 seconds. Monitoring Events The Red Event LED indicates the presence of a fault or warning in the system. To clear active events, briefly press and release the STARTUP/SHUTDOWN button n (see Figure 10 on page 32). Symbol LED On LED Flashing The XW Pro has stopped charging or inverting due to a event. The LED also turns on steadily if the unit has both a fault and a warning. The XW Pro has a warning. A warning may escalate to a fault if the warning condition does not go away. Equalizing Batteries Button Pressing the Equalize button ( symbol) for five seconds initiates a battery equalization cycle. This cycle is used to restore battery capacity when battery life has deteriorated due to sulphation. After the button is pressed the XW Pro begins a full charge cycle, which is automatically followed by an equalization cycle. Equalization functions only when AC is present and qualified and the charger is enabled. Otherwise the XW Pro generates a Cannot Equalize warning (W96). aSee the document "AC Coupling of Inverters Solutions Guide" available at http://solar.schneiderelectric.com for more information about AC coupling. 34 This document is intended for use by qualified personnel 990-91402B Monitoring Operation XW Pro Owner's Guide WARNING EQUALIZATION HAZARD n Only flooded lead acid batteries permitted by the manufacturer should be equalize charged. Hydrogen and oxygen gases are produced when batteries are equalized and can potentially cause an explosion if ignited. Corrosive battery acid can escape. n Provide adequate ventilation and remove all sources of ignition, such as open flames, sparks, electric motors, relays, light switches, etc. n Equalization voltage is significantly higher than nominal battery voltage. Detach electronics that can be damaged by high DC voltage. Failure to follow these instructions can result in death, serious injury, or equipment damage. WARNING BATTERY TYPE AND SETUP HAZARDS n Incorrect battery configurations or settings for battery types can lead to dangerously high battery temperature, fire and explosion. To avoid damaging your batteries during charging or equalization, and to minimize the risk of fire or explosion consult battery manufacturer's documentation before setting battery parameters and follow the battery manufacturer's recommended settings. n Always use and connect the Battery Temperature Sensor (BTS) unless an external BMS fulfilling this function is used. n Always verify that the configured battery type matches the battery type being used. n Custom battery settings should be configured by qualified personnel only. n When using Lithium-Ion batteries, ensure that the battery pack being used includes a Battery Management System (BMS) with safety controls. Refer to Li-Ion Battery Solution Guide (document number 990-6359) for additional information. Failure to follow these instructions can result in death, serious injury, or equipment damage. In a system where more than one device is capable of equalizing batteries (such as a system including multiple XW Pro units and/or XW Pro Solar Charge Controllers), there is no system-wide equalization command for all devices. To equalize with multiple devices, each would have to be enabled individually. Alternatively, equalization can be performed using only the selected device. During the equalization process, one device applies the equalization charge while the other devices continue to operate in synchronized charge mode, typically in float (three-stage charging) or no-float (twostage charging). LED The yellow Equalize LED indicates that the XW Pro is equalizing batteries. 990-91402B This document is intended for use by qualified personnel 35 XW Pro Owner's Guide Monitoring Operation Symbol LED On The XW Pro has begun equalizing the batteries. LED Flashing Equalization has been requested but has not begun. The XW Pro must complete a charge cycle before applying the equalization charge. Using Startup/Shutdown/Standby Modes Startup/Shutdown control When the XW Pro is operating, pressing and holding the STARTUP/SHUTDOWN button (see Figure 10 on page 32) for five seconds shuts down the unit. To return the unit to its operating state, press the STARTUP/SHUTDOWN button again. While the XW Pro is turning off, the other inverter information panel buttons stop working. The shutdown process cannot be cancelled. The XW Pro can only be restarted once the display is blank. Standby mode In Standby mode, the XW Pro stops charging and inverting. Also in Standby mode, the XW Pro disconnects its internal transfer switches which stops AC to pass through to the AC output. However, the unit remains powered and present on the Xanbus network. Lastly, in Standby mode, XW Pro basic and advanced settings can be changed and put into effect. To put the XW Pro into Standby mode, press and hold the STARTUP/SHUTDOWN button and the Equalize button simultaneously for about five seconds. The display shows Stb. To return the XW Pro to operating mode, press the STARTUP/SHUTDOWN button momentarily. Pressing the STARTUP/SHUTDOWN button momentarily while the XW Pro is operating clears active faults and warnings. Single-unit installations In a single-unit installation, when the XW Pro is shut down using the STARTUP/SHUTDOWN button, Xanbus network power is off. When Xanbus network power is off, network-connected accessories such as the Automatic Generator Start (Conext AGS) and Conext Gateway could lose power and stop operating. Conext MPPT solar charge controllers continue to operate if Xanbus network power is removed, but they do not continue to communicate with each other. If the STARTUP/SHUTDOWN button is pressed and held on a XW Pro and a Conext AGS is installed in the system, the unit stops inverting or charging immediately and shuts down completely in 120 seconds. During this time, the display shows OFF. This interval allows the Conext AGS to stop the generator after a cool down period. During the 120 second shutdown time, all network communication is blocked and the unit sends a shutdown command to all other devices in the system. As well, the inverter information panel buttons stop working. The shutdown process cannot be canceled. The XW Pro can only be restarted again once the display is blank. 36 This document is intended for use by qualified personnel 990-91402B Monitoring Operation XW Pro Owner's Guide Multiple-unit installations If the STARTUP/SHUTDOWN power button is pressed and held on a master XW Pro and a Conext AGS is installed in the system, the unit stops inverting or charging immediately and turns off completely in 120 seconds. During this time, the display shows OFF. This interval allows the Conext AGS to stop the generator after a cool down period. During the 120 second shutdown time, the master unit stops network communication and the slave units issue an external sync fault (F69) or a system configuration fault (F66). As well, the inverter information panel buttons stop working. The shutdown process cannot be cancelled. The XW Pro can only be restarted once the display is blank. In a multiple-unit installation, when a slave XW Pro is shut down, other XW Pro units continue to supply Xanbus network power and the Conext AGS and Conext Gateway continue to operate. 990-91402B This document is intended for use by qualified personnel 37 XW Pro Owner's Guide Monitoring Operation Monitoring Battery Level When the XW Pro is inverting, the row of five LEDs indicates the approximate available SOC (State of Charge) of the batteries connected to the system. This capacity reading is based on battery voltage. The battery LEDs can retrieve information from various sources depending on the devices installed in the system. SOC information is reported from one of the following devices, listed in order of priority: 1. Conext Battery Monitor (If installed) 2. Conext MPPT solar charge controller (When operating) 3. XW Pro When the XW Pro is reporting, there are five battery states from empty to full. When the available battery state is empty, no LEDs are lit. The battery is considered empty when its depth of discharge exceeds approximately 50 per cent. When the battery capacity is low, the two leftmost LEDs are lit. When the battery is at medium capacity, the four leftmost LEDs are lit. When the battery capacity is full, all five LEDs are lit. When the Conext Battery Monitor or Conext MPPT solar charge controller devices are reporting, the true SOC will be indicated on the battery level LEDs and all LEDs will be utilized. NOTE: The battery LEDs are not a precise indicator of battery level. They are to be considered a general guideline rather than an exact measurement. For greatest accuracy, install the Conext Battery Monitor (Part # 865-1080-01) or refer to the external BMS readings, if installed. Figure 11 Battery Level LEDs 38 This document is intended for use by qualified personnel 990-91402B Monitoring Operation XW Pro Owner's Guide Reading the Display Screen The numeric display screen shows the following information about the operational state of the XW Pro: n Output power in kilowatts (when the (kW) LED is lit). n Battery charger current in Amps (when the n Stb when the XW Pro is in Standby mode. (A) charging LED is lit). n Sch when the XW Pro is in Search mode. n OFF when the STARTUP/SHUTDOWN button is pressed and held for five seconds. OFF is displayed briefly before the unit turns off. n "---" appears when the XW Pro is in transition between modes, when inverter selection is disabled via the Conext Gateway, or operating in AC passthrough mode. n En appears momentarily when the XW Pro is enabled. n dIS appears momentarily when the XW Pro is disabled. n 5 minute countdown timer value may appear if there is no other more significant information to display after grid interruption during energy export operation. Monitoring Operation with the Conext Gateway The Conext Gateway provides remote configuration and monitoring capability for the XW Pro and all other Xanbus-enabled devices in the network via its browser-based web application. It is the primary and recommended way to monitor operations of all networked devices. Accessing the Device in the Web Application Refer to Logging in to the Conext Gateway Web Application in the Conext Gateway Owner's Guide to gain access to the web application. If connectivity between system components are working, networked XW Pro units can be accessed by clicking the device icon in the Dashboard screen, or its instance under the Devices menu. Status Page The XW Pro Status page displays real-time operational data specific to the selected XW Pro instance. In Tables 2 and 3 are all possible states that can be shown for Inverter Status and Charger Status. 990-91402B This document is intended for use by qualified personnel 39 XW Pro Owner's Guide Figure 12Status page Monitoring Operation Table 2 Status page inverter states Status Displayed when... Inverting The XW Pro is supplying power to loads on AC OUT by inverting power from the batteries. AC input from the utility (AC1) or generator (AC2) is absent or out of nominal range. AC Passthrough The AC connected to the AC1 or AC2 input is passing directly through the XW Pro to the loads attached to AC Out. The batteries are not being charged or discharged in this state. APS only Battery power is being consumed to power the control circuitry only. During grid outages, the inverter is disabled. To enable the inverter for grid-forming, refer to the Controls submenu in the Configuration menu. Inverter Disabled Inverter is disabled or the unit has been placed in standby mode using the Conext Gateway web application or the Standby key press (STARTUP/SHUTDOWN and Equalization) on the inverter information panel. To enable the inverter, see "Configuration" on page 49. Inverter Fault The XW Pro has an active fault. Grid Support There is AC input from the utility grid on AC1, however the priority for the XW Pro is to supply energy converted from external DC sources to the critical loads on AC Out. The XW Pro enters this state only when Grid Support is set to ON and battery voltage is above the Grid Support Voltage or SOC setting. 40 This document is intended for use by qualified personnel 990-91402B Monitoring Operation XW Pro Owner's Guide Status Displayed when... There is AC input from the generator on AC2, and the XW Pro is supporting the generator by supplying additional power to the loads attached to AC Out. The XW Pro supports the generator (or other power source connected to the generator [default AC2] input) when the AC load current drawn from the generator exceeds the Generator Support Amps setting for 1 to 2 seconds. Gen Support The XW Pro uses stored battery energy to load share with the generator until the total AC load current (generator plus XW Pro output) drops by 2 amps plus 10 per cent of the Generator Support Amps setting for 0.5 seconds. For example, if Generator Support Amps is set to 10 amps, the XW Pro starts to support when the load exceeds 10 amps for 2 seconds and stops when it drops more than 3 amps below the Generator Support Amps setting, or 7 amps (2 amps plus 10 per cent of 10 amps = 3 amps). The system can enter this state if the battery voltage is above Low Batt Cut Out +2V and generator support is enabled. Refer to "Configuration" on page 49. The XW Pro is grid-tied and is exporting energy to the utility grid on AC1. Both Selling to Grid Support and Sell must be enabled in order to sell power back to the utility. Grid Refer to "Configuration" on page 49. All configurations must comply with local and national electrical codes. Load Shaving The XW Pro supports the utility grid when there is AC input on AC1 and the current required to power the loads rises above the Load Shave Amps setting between the Load Shave Start and Load Shave Stop times set on the Grid Support menu. However, AC charging including force charging is disabled during these times. AC charging is enabled when battery voltage falls below [LBCO + 1V], or when battery SOC falls below the SOC LBCO. For an illustration, refer to Figure 17 on page 75 . When load shaving, the XW Pro uses stored battery energy to reduce the peak load on the AC1 input by providing the difference between the actual load current and the Load Shave Amps setting. The XW Pro enters this state only when Grid Support is enabled, the load shave time window is valid and the load draw exceeds the Load Shave Amps setting. The battery voltage must also be between Recharge Volts +0.5 V and the Grid Support Voltage setting or Recharge SOC and Grid Support SOC settings respectively if SOC control is enabled. Refer to "Configuration" on page 49. AC If AC Coupling is enabled, the XW Pro is modulating the incoming power from Coupling any AC-coupled PV inverters as needed via frequency-shifting. 990-91402B This document is intended for use by qualified personnel 41 XW Pro Owner's Guide Monitoring Operation Table 3Status page charger states Header 1 Header 2 Absorption Exit Pending The XW Pro has completed the absorption stage and is waiting for other XW Pro units in the system to complete absorption. This status can occur only when there is another XW Pro also charging the battery. Bulk The XW Pro is bulk charging the batteries from qualified AC input from the utility grid (AC1) or a generator (AC2). AC input is also passed through to the load while bulk charging. Absorption The XW Pro is absorption charging the batteries from qualified AC input from the utility grid (AC1) or a generator (AC2). AC input is also passed through to the load while absorption charging. Equalize Equalization has been turned on and the XW Pro is equalizing the batteries after completing a full charge cycle. Float The XW Pro is float charging the batteries from qualified AC input from the utility grid (AC1) or a generator (AC2). The XW Pro is set for three-stage charging. AC input is also passed through to the load while float charging. Constant Voltage and Current Charger Disabled Charging state when External BMS is selected for Charge Cycle. Charging functionality is disabled. To enable this, refer to "Configuration" on page 49. Qualifying AC The XW Pro is determining if AC input on AC1 or AC2 is within a usable voltage and frequency range. Qualifying AC is also displayed when the XW Pro is awaiting application of AC power or a command to enable invert mode. Qualifying APS The XW Pro is undergoing a self-test to ensure the power to the control circuitry (Auxiliary Power Supply) is adequate for use. AC Good The unit has qualified the input at AC1 or AC2 as within a usable voltage and frequency range. APS Good The unit has qualified the Auxiliary Power Supply. AC Fault The unit has encountered a fault. The fault description is displayed in the Status or Events menus along with suggested remedies. To clear the fault, refer to the Controls submenu in the Configuration menu. Charge The XW Pro is charging the batteries from qualified AC input from the utility grid (AC1) or a generator (AC2). The charge state is in transition to either bulk, absorption, float, or equalize. AC input is also passed through to the load while charging. Ground Fault A ground fault has been detected by the system.

The characters available are: n A to Z n a to z n 0 to 9 n space NOTE: Increasing the number of characters in a device name may cause other text on the same line to run off the edge of the screen. Device names should be limited to 10 characters or less. The XW Pro device name can be set at the device's Configuration page in the Conext Gateway web application under the Device Instance menu. NOTE: It is also possible to change the device name using the Conext Configuration Tool. Please refer to the Owner's Guides for the Conext Configuration Tool for further information. Setting the Device Number When several devices of the same type are installed in the Xanbus network, setting the device number is required to give a Xanbus-enabled device a unique identity. When each identical device has a unique number, the Conext Gateway web application can correctly identify and display status information for each device. A device number consists of two digits ranging from 0 (default) to 247. If only one of each type of device is installed in the networked power system, a device number is not needed. However, setting the device number to a value other than 0 is recommended in case you need to use the Restore Defaults command. This command resets the device number to 0. After performing the command, checking that the device number has returned to 0 indicates that the command was successfully completed. The Device Number can be set at the device's Configuration page in the Conext Gateway web application under Device Instance. 990-91402B This document is intended for use by qualified personnel 51 XW Pro Owner's Guide Configuration Setting the Time and Date XW Pro advanced features such as peak load shaving, charger block, and time-stamped events (faults, warnings, and logged historical data) require that the system be set to the correct time. The Conext Gateway has an internal clock that controls the time for the Xanbus-enabled devices in the system. You can set the time, time format, and date on the Clock menu. The Time Setup menu is accessible under Configuration in the Conext Gateway Setup Screen where the time zone, time, and date are adjustable. For more information, see "Changing the Time" in the Conext Gateway Owner's Guide.

The Inverter Settings menu contains settings that control when the XW Pro starts and stops producing AC output. Table 5 Inverter Settings Menu Item Description Low Battery Cut Out Low Battery Cut Out (LBCO) controls when the inverter stops producing AC output due to a low battery voltage condition. The inverter will stop producing AC output only after this level has been reached for the period of time set by the Low Battery Cut Out Delay. This setting is not temperature compensated. Low Battery Cut Out Delay Low Battery Cut Out Delay controls how long the inverter is allowed to operate at or below the Low Battery Cut Out level before turning off due to a low battery voltage condition. The inverter will stop producing AC output only after the Low Battery Cut Out level has been reached for this uninterrupted period of time. Once the inverter has shut off, the battery voltage must rise the amount of volts set in Low Battery Cut Out Hysteresis above the Low Battery Cut Out setting for inverter operation to resume. Low Battery Cut Out Hysteresis The voltage increment on top theLow Battery Cut Out parameter above which the battery voltage must be for inverter operation to be allowed to resume. 990-91402B This document is intended for use by qualified personnel 53 XW Pro Owner's Guide Configuration Item High Battery Cut Out High Battery Cut Out Delay Search Mode Maximum Search Watts Search Delay High SOC Cut Out High SOC Cut Out Delay Low Battery Cut Out SOC Description High Battery Cut Out sets the maximum battery voltage at which the inverter will operate. If the battery voltage exceeds this limit for more than 1 minute, the XW Pro displays a fault message (F49) and shuts down. The inverter will not support AC loads when in this condition. If a qualified AC source is present, the unit passes AC through to the loads. The inverter automatically restarts when the voltage drops to 6 volts below the High Battery Cut Out setting. If battery voltage continues to rise after shutdown, an external charger may still be charging the batteries. The XW Pro cannot control how external chargers operate. High Battery Cut Out Delay controls how long the inverter is allowed to operate at or above the High Battery Cut Out level before turning off due to a high battery voltage condition. The inverter will stop producing AC output only after the High Battery Cut Out level has been reached for this uninterrupted period of time. Enable or disable Search Mode. Maximum Search Watts sets search sensitivity for the XW Pro when search mode is enabled. When a load larger than this setting is present on AC OUT, the inverter starts producing AC output from battery power. Enabling search mode from the same menu can minimize power draw from the battery during periods of low demand from loads. Note that energy-efficient light bulbs may not provide enough power to wake the inverter from Search mode. Search Delay sets the time between search pulses. When searching for loads, the XW Pro sends out search pulses on AC OUT to determine the presence of a load above Search Watts. XW Pro power draw while in search mode decreases when Search Delay is increased, but the XW Pro response time to active loads is slower.

Configures the action taken during a general communications loss with the Conext Gateway. For default settings, see "Inverter Settings Menu" on page 146. Using the Low Battery Cut Out and LBCO Delay Settings WARNING ADVANCED CONFIGURATION HAZARD n Advanced menu settings should be used by qualified personnel only. n Three phase operation should be configured by qualified personnel only. n Consult with the local utility before enabling XW Pro sell mode or grid support functions. n Do not change these settings unless you are under the supervision and direction of qualified personnel. n Connect the Conext Gateway and the network router connected to the Conext Gateway to an assured power source during configuration. Failure to follow these instructions can result in death, serious injury, or equipment damage. The Low Battery Cut Out setting is the lowest battery voltage or SOC level acceptable for use by the inverter. When the batteries discharge to the Low Battery Cut Out setting, and are held at or below this level for the LBCO Delay time, the inverter output shuts down and connects any available AC source (AC1 or AC2) to the charger to bring the battery level back above the Low Battery Cut Out setting. After shutdown, the inverter does not support loads on AC OUT, and AC loads must be powered by either a generator (AC2) or grid power (AC1). If the battery voltage or SOC stays below the LBCO threshold for more than 24 hours, the XW Pro shuts down. If using the Conext Automatic Generator Start system, it is recommended to set the AGS voltage or low SOC trigger setting higher than the XW Pro Low Battery Cut Out voltage or SOC level. Although not recommended, if using the Conext Automatic Generator Start system with the start trigger set to the same voltage as the LBCO voltage, do not set the LBCO Delay for less than the amount of time it takes the generator to start and connect. Otherwise � in both of the scenarios above � inverter output turns off before the generator automatically starts, causing the battery voltage to recover slightly. This may then stop the AGS from starting the generator or result in the XW Pro cycling on and off multiple times before the generator automatically starts. 990-91402B This document is intended for use by qualified personnel 55 XW Pro Owner's Guide Configuration Using Search Mode Why use Search mode? Search mode allows the inverter to selectively power only items that draw more than a certain amount of power, which can result in energy savings. The XW Pro has a no-load power draw of about 28 watts. Enabling search mode reduces this power draw to less than 8 watts. Search mode operates differently in single-unit and multi-unit installations. Single units When a single XW Pro has search mode enabled, the inverter sends electrical search pulses through its AC output. These search pulses look for connected AC loads. The delay between search pulses is set using the Search Delay setting. After a load larger than the Search Watts setting is detected, the inverter starts producing AC output. Multiple units It is not recommended to use search mode for XW Pro inverters in a multi-unit configuration. When to set up Search mode The search mode feature is only valuable if the inverter can spend a fair amount of time "sleeping" each day. Therefore, if search mode is to be used it must be adjusted properly. The initial adjustment should be made so that the XW Pro comes on only when needed. Certain types of loads can cause search mode to work improperly. These types of loads are described in "Problem Loads" on page 115. If these kinds of loads are in the system, follow the suggestions given to resolve the problem. If the problem loads cannot be resolved, there are two workaround solutions: Disable search mode from the main XW Pro Setup menu, causing the inverter to remain at full output voltage. Use a search friendly companion load whose only purpose is to be switched on to wake up the inverter to power the load that is unable to bring the inverter out of search mode. NOTE: Search mode, by function, cannot work with clocks and timers or devices that need power 24 hours a day. Examples of devices with timers include video recorders, coffee makers with brew timers, refrigerators, and freezers with defrost timers. Examples of devices that need power 24 hours a day include telephone answering machines, alarm systems, motion detection lights, and some thermostats. When the inverter is searching the output for loads, lights that have a wattage lower than this setting may flash momentarily. 56 This document is intended for use by qualified personnel 990-91402B Configuration XW Pro Owner's Guide Charger Settings WARNING ADVANCED CONFIGURATION HAZARD n Advanced menu settings should be used by qualified personnel only. n Three phase operation should be configured by qualified personnel only. n Consult with the local utility before enabling XW Pro sell mode or grid support functions. n Do not change these settings unless you are under the supervision and direction of qualified personnel. n Connect the Conext Gateway and the network router connected to the Conext Gateway to an assured power source during configuration.

Battery Bank Capacity Selects the system battery capacity in Ah (amp hours). Setting the Battery Bank Capacity to 0 resets the charging current to its default values. Zero Ah battery capacity implies there is no absorption exit current criteria and absorption only exits when the absorption timer (default 3 hours, range 1 minute-8 hours) expires. Sets the percentage of the maximum DC output current that is available to the charger. The maximum DC output current for different models is: Maximum Charge Rate n XW Pro 8548 --140 A If multiple XW Pros are charging the same battery bank, set each inverter's Maximum Charge Rate to 1/n of the desired charge rate (where n is the number of inverter/chargers). Always refer to the battery manufacturer's specifications before setting the Maximum Charge Rate. Do not set the Maximum Charge Rate above these specifications. Maximum Bulk Charge Current Adjustable only when the Batt Type is set to Li-ion. Sets the bulk current for a lithium ion battery type. This configures the current limit when the XW Pro is in Bulk Charge Mode. However, between the maximum charge current (Maximum Charge Rate � maximum DC output current) and the value set here, the XW Pro charger will charge at the lesser of these two values. Adjustable only when the Batt Type is set to Li-ion. Sets the absorb Maximum current for a lithium ion battery type.

Maximum Float Charge Current Adjustable only when the Batt Type is set to Li-ion. Sets the float current for a lithium ion battery type. This configures the current limit when the XW Pro is in Float Charge Mode. However, between the maximum charge current (Maximum Charge Rate � maximum DC output current) and the value set here, the XW Pro charger will charge at the lesser of these two values. Charge Cycle Sets the charging method: 3-Stage (bulk, absorption, float), 2-Stage (bulk, absorption, no float), or External BMS. 58 This document is intended for use by qualified personnel 990-91402B Configuration XW Pro Owner's Guide Item Description Default Battery Temperature Selects the battery temperature charging compensation if a battery temperature sensor is not installed. In the absence of a battery temperature sensor, the charger uses one of three settings: Cool (5 �C), Warm (25 �C), or Hot (40 �C). Recharge Voltage When charger is set for 2-stage operation, sets the battery voltage level at which a new charge cycle begins. Recharge Voltage is automatically temperature compensated to be consistent with the charge voltage (also temperature compensated). Absorption Time Sets the maximum time spent in the absorption stage, before transitioning to float or no float. Charge Block Start Sets the time to halt charging on AC1 (Grid). The AC2 (Gen) port is unaffected by the XW Pro block settings. The charger block start and stop settings allow you to select when the charger stops charging on AC1. To disable the charger block function, set Charge Block Start and Charge Block Stop to the same time. Charge Block Stop Sets the time that charging on AC1 can resume. At the Charge Block Stop time, charging on AC1 is enabled again. Equalize Support Enables or disables the ability to enter an equalization cycle. Refer to the battery manufacturer's specifications to determine whether equalization is recommended. Equalize Now Set to Enable to force an equalization process. Equalize Voltage Set Selects the equalization voltage for a Custom battery type. Consult Point your battery manufacturer for equalization voltage setting. Bulk/Boost Sets the bulk voltage for a custom battery type. When set above the Voltage Set Point absorption voltage set point, this value becomes the reference for boost voltage.

This setting is the reference that the BTS uses to adjust the charging voltage when the temperature is above or below 25 �C. The following voltage thresholds are not temperature compensated: Battery Temperature Coefficient n Grid Support entry voltage n Grid Support exit voltage n Low Battery Cut-Out trigger voltage n Low Battery Cut-Out condition clear voltage The following battery voltage set points are temperature compensated: n Float exit voltage n Bulk exit voltage n Float and Gassing voltages used in Constant Voltage exit criteria n Recharge Volts n Charge Control target voltage Max Discharge Current Each Lithium Ion battery has an internal contactor and over load protection which is based on maximum current. If exceeded, the contactor may open, resulting in complete isolation of the battery pack, thus removing power to the XW Pro. In this case the Xanbus communication as well as devices powered from the XW Pro could become unusable. When the XW Pro current draw exceeds the set value for a period defined in Max Discharge Time Interval, the XW Pro disables INV output. Max Discharge Time Interval Allows the XW Pro current in Invert mode to exceed the Max Discharge Current limit for inrush periods to startup loads such as pumps/motors. When the timer expires, the XW Pro disables INV output. Bulk Termination Time Sets the time delay to exit the bulk charging stage once the absorption voltage has been reached or exceeded. Absorption Period Timeout Sets the time period that the XW Pro will remain in the absorption charge stage Recharge SOC Sets the SOC at or under which the XW Pro will terminate any discharging activity and begin to charge the battery if a qualified AC source is available.

Battery Charger Functions When AC power is available, the XW Pro can operate as a battery charger. Different battery types and chemistries require different charging voltage levels. Not charging batteries at the required levels can shorten battery life or damage the batteries. The XW Pro is configured at the factory to work with the battery types recommended for inverter applications. If the default settings do not work for your specific installation, you can adjust the charge stage settings (as recommended by the battery manufacturer) by setting the Battery Type to Custom. NOTE: This information is provided for guidance only. Variations in battery chemistry and site-specific environmental considerations mean that you should consult your system designer or battery manufacturer for specific recommendations for appropriate battery voltage and current settings. Battery Monitoring The following table illustrates how to configure the XW Pro for the available battery monitoring methods. 990-91402B This document is intended for use by qualified personnel 61 XW Pro Owner's Guide Configuration Battery Type No External Battery Monitoring Conext Battery Monitor Any1 Any External Battery Management System (BMS) Li-ion Charge Cycle State of Charge Control 2-stage or 3-stage Disabled 2-stage or 3-stage External BMS Enabled Enabled Without any external battery monitoring, XW Pro operational state transitions, charge control, and AC coupling functions are completely based upon the measured battery voltage. The Conext Battery Monitor is a dedicated piece of hardware that determines the hours of battery-based runtime and battery bank state of charge, and shares this information with other devices on the same Xanbus network. With the Battery Monitor installed, enabling State of Charge Control is recommended. State transitions will be based on the reported State of Charge and will utilize the corresponding SOC threshold settings. Charge control will still be based on battery voltage. Typically installed with lithium-ion battery packs, external battery monitoring systems take on a more extensive role in monitoring the battery and ensuring it does not operate outside of its safe parameters. When Charge Cycle is set to External BMS, charge control on the XW Pro will be based on the SOC readings from the BMS and will utilize the corresponding SOC threshold settings. Multi-Unit Charger Settings NOTICE DAMAGE FROM HAVING DIFFERENT CHARGER SETTINGS n Make sure that all XW Pro units in the multi-unit setup have the same Charger Settings. For example, if one unit has a Battery Type of Flooded, all XW Pro units must have the same Battery Type. To copy the settings to one unit from another, see Configuration with the Conext Gateway Web Application on page 50. n Make sure that all Xanbus devices in the same network, such as connected MPPT solar charge controllers and the Battery Monitor, have the same Charger settings. Refer to each device's owner's guide for information on how to change the charger settings. Failure to follow these instructions can result in battery damage. NOTE: Make sure that every XW Pro unit in the multi-unit configuration is set to Charger = Enabled under the Controls menu for each inverter. Multi-Stage Charging Process The charging cycle is a multi-stage process. Whenever qualified AC power is present at the AC1 or AC2 input, power runs through to the connected load and begins charging the 1 When using Lithium Ion, the flat voltage profile introduces difficulty in precisely monitoring state of charge. A BMS or Conext Battery Monitor is highly recommended in these applications. 62 This document is intended for use by qualified personnel 990-91402B Configuration XW Pro Owner's Guide batteries in parallel. Bulk Stage Bulk charge is the first stage in the charging process and provides the batteries with a controlled, constant current. Once the battery voltage rises to the Absorption Termination Voltage, the charger switches to the absorption stage. Absorption Stage During the absorption stage, the XW Pro begins operating in constant voltage mode and the DC charge current falls gradually as energy is returned to the battery. For the first 60 minutes of the absorption stage, the XW Pro regulates the battery voltage at the Bulk/Boost Voltage Set Point setting. The voltage limit used for the remaining time in this stage is the Absorption Voltage Set Point setting. By default, the bulk and absorption voltage settings are the same for each battery type. The voltage limit settings for bulk and absorption can be adjusted independently if the battery type is set to Custom. The XW Pro transitions to the float stage if either one of the following two conditions are met: The charge current allowed by the batteries falls below the exit current threshold, which is equal to 2% of the programmed battery capacity (for a 500 Ah battery bank, this would be 10 A), for three minutes. The XW Pro has been in absorption for the programmed maximum absorption time limit. The default is 3 hours, but the time limit is programmable from 1 minute to 8 hours. The timer begins when the battery voltage is above the Absorption Termination Voltage for three minutes. NOTE: If there are DC loads on the batteries, the charger's current may not decrease to a level to transition to the next stage of charging. In this case, the charger stays in absorption until the Absorption Time setting is reached. To avoid having the charger remain in absorption for too long, adjust Absorption Time on the Charger Settings menu. The timer begins at the start of the absorption stage and terminates absorption charging if the charge current does not decrease to below 2 per cent of the battery capacity before the Absorption Time setting expires. The Absorption Time setting may be increased if the charge cycle continually runs the complete Absorption Time in the absence of DC loads. This is an indication of too large a battery bank for the selected Absorption Time setting. 990-91402B This document is intended for use by qualified personnel 63 XW Pro Owner's Guide Configuration Boost Charging n Boost charging allows for better utilization of flooded lead acid batteries under moderate cycling in off-grid or grid support applications. Boost charging encourages a short duration charging voltage--above the gassing voltage--at the beginning of the absorption charge state. Testing has shown that boost charging improves battery performance by providing a regular mixing of the liquid electrolyte. Boost charging specifically discourages capacity robbing acid stratification and plate sulfation. n Boost mode charging can be enabled by selecting the Custom battery type and by setting the Bulk/Boost Voltage Set Point higher than the absorption voltage. The multi-stage charge algorithm then attempts to use the higher voltage for the first hour of the absorption stage, unless it is interrupted by the max absorption timer or exit current threshold. n Boost charging encourages gassing of flooded lead acid batteries. n Boost charging is NOT recommended for AGM, GEL or any other electrolyte-limited and/or valve-regulated sealed battery application. n Boost charging may result in higher than normal water consumption. However, the benefits of boost charging are likely to be greater than the extra watering effort. Check battery water levels at least once per month. n Boost charging has maximum benefit when used on batteries that experience moderate cycling. An unoccupied cottage, for example, where batteries are full the majority of the time may not benefit from boost charging, especially if battery watering is difficult. n For equalize charging, a custom Boost charge profile can be configured if the equalize method is not periodically used. Boost charging occurs in the first hour of the absorption stage. It allows for a higher constant voltage than absorption voltage to encourage a "mini equalize" each time the battery is charged. n The boost voltage is defined by the Bulk/Boost Voltage Set Point setting. The Conext system will still allow manual equalize charging when the boost absorption voltage is implemented. This is for advanced users only who pay strict attention to battery maintenance and have an appropriately vented and protected battery installation. Consult your battery manufacturer for appropriate voltages. 64 This document is intended for use by qualified personnel 990-91402B Configuration XW Pro Owner's Guide Float Stage Float charge maintains the batteries slightly above the self discharge voltage of the batteries. The charge current in float is the current necessary to maintain the batteries at the Float Voltage setting, limited only by the inverter's capability or other settings that limit the inverter's maximum charge rate. Float charging reduces battery gassing, minimizes watering requirements (for flooded batteries), and helps the batteries remain in a constant state of readiness. When three-stage charging is selected, the charger automatically switches to the float stage after the batteries have received a bulk and absorption charge. The batteries are maintained at the default float voltage level for the selected battery type or the voltage selected under Float Voltage Set Point on the Charger Settings menu. NOTE: The battery voltage can increase above the float voltage when using an external charging device such as charge controllers attached to PV arrays, wind turbines, and micro-hydro generators. Be sure to include appropriate charge management equipment with all external DC sources. Three-Stage Charge Cycle The three-stage charge mode includes bulk, absorption and float stages described above. The three-stage charge mode is not used with generators or grid-tied systems where grid support features are used. Two-Stage Two-stage (or no float) mode differs from an ordinary three-stage charge mode in that it does not continuously maintain the battery at float voltage. Instead, the XW Pro begins charging the battery in bulk mode whenever the battery voltage drops below the recharge level. While the battery voltage is above the recharge level the inverter's AC transfer switch continues to pass through power from the utility grid to the loads, but does not actively charge the batteries. Two-stage mode increases efficiency of utility connected systems by reducing the amount of power consumed by the inverter and batteries compared to when the battery is continuously maintained at Float Voltage. This feature can extend the life of many batteries. Unless an external BMS is installed and Charge Cycle is set to External BMS, to allow grid support and sell mode to function after battery charging has completed, it is recommended to set Charge Cycle to 2-stage. 990-91402B This document is intended for use by qualified personnel 65 XW Pro Owner's Guide Figure 15 Two-Stage Charging Cycle Configuration Battery Voltage Bulk Stage Absorption Stage (Boost Stage) Absorption Voltage Recharge Voltage 2-Stage Charge Custom Charge Battery Current Max Charge Rate Boost Timer 1hr fixed Max Absorb Time - Dflt 3 hrs (adjustable 1 min - 8 hrs) Return to Bulk Stage Time Absorption Exit Current Threshold = 2% of programmed AH capacity Time Charge Cycle Notes n When the charge cycle is interrupted, the charger will restart charging at the beginning of the multi-stage algorithm. n If the AC input stops or drops below the lower VAC limit (as set in AC Settings), the complete multi-stage charge cycle (bulk, absorption, float/no float) restarts once the source AC recovers to within the acceptable range. If n Exit Current Threshold can be effectively disabled by programming the amp-hour capacity to 0. In this case, absorption will only exit once the Max Absorption timer expires. n Charge current during equalize state (optional state not shown here) is normally limited to 10% of the programmed amp-hour capacity setting. If this setting is programmed to 0 Ah, the charge current during equalize is instead limited to whatever is programmed for the maximum current limit of the unit (the default current limit in equalize mode is 60 A). n Synchronized charge states are active when more than one charging device (XW Pro or Conext MPPT solar charge controller is connected in the system via the Xanbus network. n The first XW Pro or Conext MPPT solar charge controller to enter bulk, causes the other chargers to enter bulk. n The first XW Pro to enter absorption causes the other chargers to enter absorption. 66 This document is intended for use by qualified personnel 990-91402B Configuration Equalize Charging XW Pro Owner's Guide n The last XW Pro ready to exit absorption triggers the rest to exit absorption and exit charge. The XW Pro will not wait for any connected Conext MPPT solar charge controllers to transition to absorption or float. Many lead acid battery manufacturers recommend periodic equalize charging to counter cell charge imbalance and capacity robbing sulphation. Equalizing helps to improve battery performance and lifespan by encouraging more of the battery material to become active. Battery equalization is a controlled overcharging method that reduces sulphation and mixes up stratified electrolyte and reactivates unused areas of the plate material. Periodic equalizing can help to regularly restore flooded lead acid batteries to a healthy state of charge. Consult the battery manufacturer's recommendation for equalize charging settings. Sealed lead acid, gel, AGM, and lithium ion batteries should not be equalized unless recommended by the battery manufacturer. Consult the battery manufacturer for optimal charging procedures when using sealed batteries. When Equalize mode is enabled, the battery is charged from bulk to absorption, and then to the equalize phase. The XW Pro will transition from the absorption phase to equalize if: n The DC charge current is below 2% of the configured battery capacity (for example, 8.8 A for 440 Ah). n The absorption time is exceeded (for example, 180 minutes). After absorption, the maximum charge DC current is set to 10% of battery capacity (for example, 44 A for 440 Ah). This constant current charge will continue until the voltage has increased to the equalize voltage at which point the battery will be regulated at the temperature compensated equalize voltage. If the battery capacity is set to zero, the equalize charge current is fixed at maximum 44 A (Ah=0 effectively disables the exit current criteria for the absorption charge stage, making the absorption stage defined by time only). Equalization duration is fixed at one hour.

On the Charger Settings menu, toggle the Equalize Now toggle switch to Enabled. 2. Press the Equalize button on the inverter information panel for five seconds. If the XW Pro will not perform the equalization, see Warning W96 "Cannot Equalize" in Table 23 on page 122. WARNING EQUALIZATION HAZARD Only flooded lead acid batteries should be equalize charged. Hydrogen and oxygen gases are produced when batteries are equalized and can potentially cause an explosion if ignited. Corrosive battery acid can escape. n Provide adequate ventilation and remove all sources of ignition, such as open flames, sparks, electric motors, relays, light switches, etc. n Equalization voltage is significantly higher than nominal battery voltage. Detach electronics that can be damaged by high DC voltage. Failure to follow these instructions can result in death, serious injury, or equipment damage. NOTE: In a system where more than one device is capable of equalizing batteries (such as a system including multiple XW Pro units and Conext MPPT solar charge controllers, there is no system-wide equalization command for all devices. To equalize with multiple devices, each would have to be enabled individually. Alternatively, equalization can be performed using only one device. During the equalization process, one device applies the equalization charge while the other devices continue to operate in synchronized charge mode, typically in float (three-stage charging) or no-float (two-stage charging). WARNING ADVANCED CONFIGURATION HAZARD n Advanced menu settings should be used by qualified personnel only. n Three phase operation should be configured by qualified personnel only. n Consult with the local utility before enabling XW Pro sell mode or grid support functions. n Do not change these settings unless you are under the supervision and direction of qualified personnel. n Connect the Conext Gateway and the network router connected to the Conext Gateway to an assured power source during configuration. Failure to follow these instructions can result in death, serious injury, or equipment damage. This document is intended for use by qualified personnel 69 XW Pro Owner's Guide Configuration The AC Settings menu configures the voltage and frequency limits for AC port 1 (Grid) and AC port 2 (Gen). These are the limits at which the XW Pro considers AC input voltage qualified--that is, suitable for charging batteries or passing through to loads attached to AC OUT. If the input voltage is not qualified according to these settings, the XW Pro reverts to inverting external DC energy to AC energy for loads on AC OUT. Table 7 AC Settings Menu Item Description Sets the priority for the AC input source (AC1 or AC2) for qualification and transfer. AC Priority In systems that use both utility grid (AC1) and generator (AC2) input, it is recommended that you set AC Priority to AC1. Assuming the generator is intended for occasional use only, the XW Pro will use utility power. It will use the generator only if AC1 is unavailable, and if the generator is running. AC1 Breaker Sets the AC1 (Grid) breaker size, based on the size of the breaker installed upstream from the AC1 connection port. The installed breaker size must not exceed the capacity of the upstream distribution panel. The XW Pro helps to limit the maximum current draw on AC1 by derating its charging current to an equivalent of 80% of the AC1 breaker setting. However, if the connected loads on AC OUT exceed the AC1 breaker setting, the upstream AC breaker trips. The breaker may not trip if grid support is enabled and battery voltage is above the Grid Support Voltage setting, or if peak load shave is enabled and the load shave time window is active. AC1 Low Voltage Disconnect Minimum acceptable input voltage level from the utility grid, below which the inverter will disconnect.

This document is intended for use by qualified personnel 71 XW Pro Owner's Guide Configuration Item Description AC2 Breaker Sets the AC2 (Gen) breaker size, based on the size of the installed AC breaker upstream from the AC2 connection port. The installed upstream breaker and the AC2 breaker set point must not exceed the capacity of the generator. The XW Pro helps to limit the maximum current draw on AC2 by derating its charging current to an equivalent of 80% of the AC2 breaker setting. However, if the connected loads on AC OUT exceed the AC2 breaker setting, the upstream AC breaker trips. The breaker may not trip if Gen Support is enabled and Gen Amps is configured not to exceed the generator's rated output current. AC2 Low Voltage Disconnect Minimum acceptable input voltage level from the utility grid, below which the inverter will disconnect. AC2 Low Voltage Reconnect Offset Determines the reconnect level relative to AC2 Low Voltage Disconnect. AC2 Low Voltage Disconnect plus AC2 Low Voltage Reconnect Offset equals the voltage at which the inverter reconnects. AC2 High Voltage Maximum acceptable input voltage level from the utility grid, above Disconnect which the inverter will disconnect. AC2 High Voltage Reconnect Offset Determines the reconnect level relative to AC2 High Voltage Disconnect. AC2 High Voltage Disconnect plus AC2 High Voltage Reconnect Offset equals the voltage at which the inverter reconnects. AC2 Low Voltage Time Delayed Disconnect Input voltage level from the utility grid, below which the inverter will have a delay of AC2 Time Delayed Disconnects Delay before disconnecting.

AC2 Transfer Switch The time delay between qualifying AC2 and closing its contactor. Delay The trip time needed to activate fault F72 if the external contactor External Contactor command does not match the actual status of the external contactor. Mismatch Fault Delay Adjust this parameter to account for varying close and opening times of the contactors available for use. Inverter to Grid Overlap The time delay from closing the external contactor (if equipped) due to grid qualification to exiting grid-forming operation. Depending on the external contactor installed, this value must be tuned to accommodate its closing time reliably. By default, this value is set to 0.015 seconds. Grid to Invert Delay The time delay from opening the external contactor (if equipped) due to a grid outage to grid-forming operation. Depending on the external contactor installed, this value must be tuned to accommodate its opening time reliably. By default, this value is set to 0.1 seconds. For default settings, see "AC Settings Menu" on page 148. Configuring Nominal Grid Frequency This adjustment is performed by selecting the appropriate compliance region for each XW Pro. For instance, by selecting Australia, the unit being configured will adopt a 50 Hz nominal grid frequency. All frequency-related functions, including over/underfrequency detection, are based upon these settings. Refer to "Managing Compliance Regions" on page 99 for information on how to select a compliance region. Grid Support Settings The Grid Support Settings menu contains configuration options for grid-tie operation. To enable these settings, Grid Support must be enabled in the Grid Support menu. Individual 990-91402B This document is intended for use by qualified personnel 73 XW Pro Owner's Guide Configuration grid-interactive features such as PLS and Sell are enabled individually. In grid support mode, the XW Pro supports the utility grid by limiting the power drawn from the utility to close to zero. This mode is desirable for using excess energy from auxiliary DC sources like PV, while still maintaining a charged battery bank. No power is sold to the utility in this mode. NOTE: Grid support and sell functions are modes of operation that are subject to local and/or national grid interconnection requirements in most jurisdictions. It is the responsibility of the installer and system operator to ensure that all applicable procedures and technical requirements are complied with before turning on either of these modes. The interconnect codes and standards with which the XW Pro complies are listed in "Mechanical and Regulatory Specifications" on page 138. NOTE: Upon startup, the XW Pro does not enable grid support functions for one minute (60 seconds). During this period the XW Pro connects to AC input and determines whether the utility grid voltage and frequency are stable and within nominal range. If Grid Support is enabled, the inverter information panel also displays a 60 second countdown during this period. For more information, see "Islanding Protection" on page 25. NOTE: In grid support mode, the XW Pro should not draw a large amount of current from the grid. If the XW Pro is drawing more than expected, it is important to note that it cannot distinguish between real power and reactive power. Large current draw will only affect reactive power and not real power, and utility companies generally only charge by real power consumed. Table 8 Grid Support Menu Values Setting Description Grid Support Turns the Grid Support feature on and off. Grid Support Voltage Sets the voltage level above which Grid Support features are enabled.

Below this level, excess power from the PV inverters would charge the battery. As the actual SoC approaches this level, the XW Pro will shift the grid forming frequency to moderate the PV inverter output power as to prevent further charging of the battery. Takes effect when State of Charge Control is enabled Sell Block End The time of day when the selling of power to the grid is no longer permitted. State of Charge Control Enable if equipped with a Conext Battery Monitor or an external BMS (Eg. With lithium-ion batteries) to utilize State of Charge to control mode transitions instead of battery voltage. Grid Support SoC The SoC threshold above which grid support features are enabled. This threshold takes effect when State of Charge Control is enabled Grid Support SoC Exit Delay Sets a delay period between when SoC falls below the Grid Support threshold and when grid support functions cease.

Figure 17 Load Shave Mode 990-91402B State of Charge Control Different battery chemistries have associated charge and discharge SOC (State of Charge) versus voltage profiles. Some batteries, such as lead acid, have reasonably This document is intended for use by qualified personnel 75 XW Pro Owner's Guide Configuration large changes in battery voltage across the nominal operating range of 20-80% SOC, allowing the inverter to control battery charging and discharging based on measured voltage. Other batteries, such as Li-ion, have a very small change in voltage across the nominal 20-80% SOC operating range making control decisions based on battery voltage difficult (see Figure 18 for illustrative purposes only). To accommodate battery chemistries such as these, SOC-based control can be enabled in the XW Pro under the Grid Support menu in the Configuration tab of the Conext Gateway web application. When enabled, all SOC-based threshold configurations for transitioning between operating modes shall take effect, and their voltage-based counterparts shall be deactivated. Figure 18 SOC vs. voltage for battery profiles The battery SOC is typically calculated by a third-party Battery Management System, Conext Battery Monitor, or any other external device with such a function. The BMS also ensures safe operation of the batteries by establishing operational limits for the attached inverter-charger unit. With lead-acid, the XW Pro utilizes battery voltage to transition between operational modes. A duplicate set of SOC-based thresholds are used when State of Charge Control is enabled, and their voltage-based counterparts are ignored. The following figure depicts the SOC settings available assigned with some typical values. Figure 19 State of Charge Thresholds 76 This document is intended for use by qualified personnel 990-91402B Configuration XW Pro Owner's Guide Generator Support Settings WARNING ADVANCED CONFIGURATION HAZARD n Advanced menu settings should be used by qualified personnel only. n Three phase operation should be configured by qualified personnel only. n Consult with the local utility before enabling XW Pro sell mode or grid support functions. n Do not change these settings unless you are under the supervision and direction of qualified personnel. n Connect the Conext Gateway and the network router connected to the Conext Gateway to an assured power source during configuration. Failure to follow these instructions can result in death, serious injury, or equipment damage. Generator support allows power to be automatically drawn from the batteries to assist an AC generator on AC2 to support heavy loads on AC OUT (loads that exceed the available power from the generator). Generators have a limited output current and it is possible to reach this limit when operating heavy loads. The XW Pro is designed to assist the generator when heavy current demands load down the generator by supplying additional power from the batteries. In addition, the battery charger can reduce its charging current to the batteries so the combined AC current required for charging and the total load current do not exceed the capacity of the generator or trip its output breakers or fuses. For imbalanced loads and small generators, the generator support feature may be used. When Generator Support Plus is enabled, the XW Pro will connect the center of its transformer to the AC2 input neutral to act as a load balancing transformer. This feature will attempt to balance the load between L1 and L2. Generator support is most effective for generators under 5 kW. See "Advanced Features" on page 85. NOTE: The passthrough running and startup (peak) currents of generators attached to AC2 are limited to the maximum current limits of the XW Pro. NOTE: If generator support is used with generators larger than 5 kW, it is possible for current to recirculate. In this case, the efficiency losses would outweigh the benefit of generator support. 990-91402B This document is intended for use by qualified personnel 77 XW Pro Owner's Guide Figure 20 Gen Support Mode Graph Configuration Ensure that the battery bank has sufficient energy to support your loads for the anticipated time period, otherwise draining the battery to LBCO may put the system in Fault mode. Table 9 Generator Support Menu Values Setting Description Generator Support Mode Turns the Generator Support feature on and off. Generator Sets the generator load level at which the XW Pro supplies power Support Amps from the batteries to support the generator. NOTE: When Generator Support Mode is enabled and actively operating, the XW Pro compensates for active power as a reference for controlling the total current as specified in the Generator Support Amps setting. However, there is also reactive power that is not compensated for by the XW Pro. For example, if Generator Support Amps is set to 48A, the inverter will only start to assist the generator at a current level which would measure approximately 49A which is 1A higher than the Generator Support Amps value. For default settings, see Generator Support Menu on page 151. AGS Setting in a Multi-Unit System To prevent the generator from nuisance cycling when the multi-unit XW Pro units are installed with an external contactor (that is, the generator starts and stops in a loop) set Inverter Load Start/Stop Triggers to Disabled under the AGS device Configuration menu in the Conext Gateway web application. 78 This document is intended for use by qualified personnel 990-91402B Configuration XW Pro Owner's Guide Auxiliary Output Settings WARNING ADVANCED CONFIGURATION HAZARD n Advanced menu settings should be used by qualified personnel only. n Three phase operation should be configured by qualified personnel only. n Consult with the local utility before enabling XW Pro sell mode or grid support functions. n Do not change these settings unless you are under the supervision and direction of qualified personnel. n Connect the Conext Gateway and the network router connected to the Conext Gateway to an assured power source during configuration.

The auxiliary output provides 12 volts DC at 250 milliamps to power a relay, indicator light, or alarm. NOTE: Changing Auxiliary Output Trigger Level resets the auxiliary output. If an auxiliary output trigger is active, changing the trigger level will clear the trigger. For default settings, see "Auxiliary Menu" on page 152. Table 10 Auxiliary Menu Values Setting Description Auxiliary Output Active Level Sets the mode (polarity) of the auxiliary output. When triggered, the output can be active high (12 V output turns on) or active low (output is high until the trigger turns it off). Auxiliary Output Selects the desired condition (trigger source) to activate the Trigger Source auxiliary output. The following parameter set controls the activation and de-activation conditions for the Auxiliary Output and are available for each trigger source. Table 11 Auxiliary Menu Values Setting Description Trigger Set Sets the voltage or temperature level (depending on the selected trigger source) at which the auxiliary output is activated. If the selected Trigger Source is a battery voltage, the range also varies according to the nominal battery voltage of your system. Trigger Set Delay Sets a delay period between when the trigger occurs and when the auxiliary output is activated. Trigger Clear Sets the voltage or temperature level (depending on the selected trigger source) at which the auxiliary output becomes inactive. 990-91402B This document is intended for use by qualified personnel 79 XW Pro Owner's Guide Configuration Setting Trigger Clear Delay Description Sets a delay period between when the Trigger Clear setting occurs and when the auxiliary output becomes inactive.

Low Battery Temperature Activates the auxiliary output when the battery temperature falls below Low Battery Temperature for the trigger delay time. The auxiliary output turns off when the battery temperature rises above the clear setting for the Clear Delay time. Battery temperature is measured with a battery temperature sensor. Do not use this setting if a battery temperature sensor is not installed. High Battery Temperature Activates the auxiliary output when the battery temperature rises above High Battery Temperature for the trigger delay time. The auxiliary output turns off when the battery temperature falls below the clear setting for the Clear Delay time. Battery temperature is measured with a battery temperature sensor. Do not use this setting if a battery temperature sensor is not installed. With this setting, the auxiliary output can turn on a fan to vent the battery compartment. 80 This document is intended for use by qualified personnel 990-91402B Configuration XW Pro Owner's Guide Heat Sink Overtemperature Bulk Exit Absorption Exit Fault Battery Low State of Charge Time of Day Activates the auxiliary output when the heat sink temperature exceeds its trigger set for longer than its set delay. The auxiliary output turns off when the temperature falls below its clear threshold for longer than its clear delay. Exits charge bulk mode. In charge bulk mode, the XW Pro operates as a constant power source to the battery bank. The aux port clears its state when the inverter exits from Bulk charge stage. Exits charge absorption mode and starts the following mode, depending on whether the unit is set to two or three-stage charge. The aux port clears its state when the inverter exits from Absorption charge stage. Activates the auxiliary output when a fault occurs. The auxiliary output clears when the fault is cleared.

Failure to follow these instructions can result in death, serious injury, or equipment damage. The Associations menu contains additional settings to allow the XW Pro to function as part of a multi-unit networked system. Setting the connections for a Xanbus-enabled device provides a way of identifying nonnetwork associations for Xanbus-enabled devices and enhancing networked power system management. When connections are set, devices of different types become associated and can share sources, e.g. a common DC input source, or a common grid/generator source. In multi-unit networked systems, multiple inverter/chargers can be stacked to produce increased charge current. To achieve this functionality, the devices must be configured to the same DC connection, such as House Battery Bank 1. The units will collaborate on battery charging by communicating with other units on this shared DC connection. NOTE: When configuring clusters of three XW Pro units (or a grouping of up to six in a grid-tie application), each cluster's DC connections must be set to the same battery bank. If one of the units is set with a different DC connection, a system configuration fault (F66) occurs. Table 14 Associations Menu Item Description DC input and output connection.

Enable this setting if an external switch has been connected to the XW Pro auxiliary port. See the XW Pro Installation Guide for more information about the auxiliary port. Power Save When enabled, power save mode can reduce tare loss from the battery by reducing output from 230 volts to 213 volts when the loads are less than 100 watts. When the XW Pro detects loads higher than 100 watts, it produces the full 230 volts. Power Save mode is disabled by default. Sell Delay 40 Sec When enabled--and other conditions are satisfied--there will be a 40 second delay before the system starts exporting energy to the grid. When disabled, the default value of 20 seconds is used. This feature is useful when the battery voltage is not constant. It also helps avoid power fluctuations during sell. As an exception, there will be zero time delay when the battery voltage suddenly rises to 2 V above Grid Support Voltage. For example, a wind turbine or micro hydro connected to a small battery bank may create a sudden change on the battery voltage. In this case the system will immediately respond to convert the energy from the battery to grid. Generator Support Plus When Generator Support Plus is enabled, the XW Pro will connect the center of its transformer to the AC2 input neutral to act as a load balancing transformer. This feature will attempt to balance the load between L1 and L2. See "Generator Support Settings" on page 77 for more details.. AC Coupling AC Coupling function is enabled by default (Advanced Features Menu) and should remain enabled except in cases where the DC voltage level is allowed to have large variations and the AC line frequency needs to remain constant. Battery Energy Balance The Battery Energy Balance function is disabled by default and is intended for use with inverters drawing power from a single battery bank. The Battery Energy Balance function should be enabled when XW Pro units are used in multi-unit systems with multiple battery banks. When enabled this feature helps balance the power draw across multiple battery banks. Peak Load Shaving Delay When enabled, Peak Load Shaving mode is delayed by 2 hours to allow the MPPT solar charge controller to charge the battery bank first, then when the timer of 2 hours expires, the unit enters Peak Load Shaving mode for AC load support. 86 This document is intended for use by qualified personnel 990-91402B Configuration XW Pro Owner's Guide Item External Transfer Contactor External Load Switch Description Enable if an external transfer contactor between the grid point of connection and the Inverter-Chargers is present.

Grid Support WARNING ADVANCED CONFIGURATION HAZARD n Advanced menu settings should be used by qualified personnel only. n Three phase operation should be configured by qualified personnel only. n Consult with the local utility before enabling XW Pro sell mode or grid support functions. n Do not change these settings unless you are under the supervision and direction of qualified personnel. n Connect the Conext Gateway and the network router connected to the Conext Gateway to an assured power source during configuration. Failure to follow these instructions can result in death, serious injury, or equipment damage. NOTE: Grid support and sell functions are modes of operation that are subject to local and/or national grid interconnection requirements in most jurisdictions. It is the responsibility of the installer and system operator to ensure that all applicable procedures and technical requirements are complied with before turning on either of these modes. The interconnect codes and standards with which the XW Pro complies are listed in Specifications. The grid support mode allows the XW Pro to support local loads by converting excess capacity from external DC sources connected to its battery bank. Examples of external DC sources are solar charge controllers and batteries. For Grid Support to function, Grid Support must be enabled on the Grid Support menu and either the battery voltage must be above the Grid Support Voltage setting or SoC must be above Grid Support SoC setting, depending on whether or not State of Charge Control is enabled.". There are two modes of operation within Grid Support. Grid Support Enabled, Sell Disabled In this mode, available excess DC power is converted and used to power local loads. No power is exported to the utility. If the local load demand exceeds the available power from the external DC sources, power is then drawn from the utility to support the load. However, if the local load demand is less than the power available from external DC sources, the net excess power from the external DC sources is not converted and hence not used. 92 This document is intended for use by qualified personnel 990-91402B Configuration XW Pro Owner's Guide Grid Support Enabled, Sell Enabled In this mode, all available excess DC power is first used to power local loads. Any remaining power is exported to the utility grid. Note: To comply with anti-islanding requirements, in a grid tied AC coupled system, change the AC1 Transfer Delay setting under AC Transfer Configuration to 300 seconds. Sell Block The sell block feature halts the export of energy to the grid connected to AC1 for a period of time each day. This period of time is defined by the Sell Block Start and Sell Block Stop settings. Sell Block can be useful in managing the self consumption of renewable energy. Note: Sell block will not block selling from an AC coupled inverter. Grid Support and Battery Charging Charge Cycle Settings With the charger enabled, the XW Pro enters grid support mode only after completing a charge cycle when it is first powered up or reconnected to the grid. Unless an external BMS is installed with Charge Cycle set accordingly, set the XW Pro Charge Cycle to two-stage (default) to allow grid support to function immediately after the absorption charge stage is completed. See "Charger Settings" on page 57 for more information. NOTE: Only the XW Pro needs to be set to two-stage charging. The Conext MPPT solar charge controllers can remain set for three-stage charging. The XW Pro should be set in two-stage charging and the charge controllers set in three- stage for solar charging to occur properly. Alternately, charger block can be used to for correct charging. See "Charger Settings" on page 57 for further information. Grid Support modes Grid Support can be configured to operate in one of two modes: n Grid Support with DC Sources Not Communicating Over Xanbus n Enhanced Grid Support with Conext MPPT Solar Charge Controllers At this time, State of Charge Control is not supported with any sort of DC-coupled sources. Grid Support with DC Sources Not Communicating Over Xanbus This setup is suitable for use with DC sources (such as wind turbines, DC generator sets, fuel cells, and so on) that do not communicate with the XW Pro through Xanbus or for mixed systems which have both Xanbus-connected Conext Solar Charge Controllers and other DC sources (such as those listed above). Grid Support Voltage is set 0.5 volts below the voltage provided by the DC source (typically the float voltage setting of the DC source or charge controller). See Figure 16 on page 68. Schneider Electric does not provide support for these energy sources. 990-91402B This document is intended for use by qualified personnel 93 XW Pro Owner's Guide Configuration In a `fixed' battery voltage system configuration, the XW Pro manages the battery voltage to the Grid Support Voltage setting. This is done by converting the available DC power to AC power to support the AC loads attached to the inverter output or exports to the utility grid (AC1). Because the battery bank voltage may not reach bulk/absorption voltages in this mode, it is recommended to occasionally force a full charge cycle by either temporarily disabling grid support or forcing a bulk charge cycle from the grid (see Force Charger State in "Controls Settings" on page 52). Enhanced Grid Support with Conext MPPT Solar Charge Controllers This setup is suitable for Conext Systems with only Conext MPPT Solar Charge Controller(s) networked to XW Pro units through Xanbus. In this configuration, Grid Support Voltage is set above the charge controller's Equalization voltage (for example, 64 volts). In an enhanced grid support set up the XW Pro automatically tracks the Conext MPPT Solar Charge Controller voltage as it transitions through charge states (from bulk to absorption to float). This allows the system to execute a complete battery charge cycle while still converting excess DC power to AC power to support the AC loads or be exported to the utility grid. In doing so, the XW Pro only uses excess DC not required by the battery or used to support local AC loads and sells it to the grid, thereby maximizing the use of the PV array. Since this set up allows the battery bank voltage to reach absorption levels (when PV harvest is adequate), the state of health of the battery is improved. The sell entry and regulation voltage level is 1 V below absorption and float of the Conext Solar Charge Controller set points. The exit from sell is 1.5 V below absorption and float of the Conext Solar Charge Controller set points. Figure 22 Charger Block NOTE: [Tdelay] is an entry/exit transition time delay to/from grid support and sell mode. If the battery voltage has higher fluctuations due to DC renewable sources (e.g. charge controllers, wind turbines, and so on), then the time delay can be increased (refer to "Advanced Features" on page 85). If the battery voltage has a sudden increase change greater than Grid Support Volts + 2 V, then the XW Pro will override the delay and enter grid support or sell mode immediately. 94 This document is intended for use by qualified personnel 990-91402B Configuration XW Pro Owner's Guide Charger Block The charger block feature halts charging on AC1 (Grid) for a period of time each day. This period of time is defined by the Charge Block Start and Charge Block Stop settings. In areas where the utility charges variable rates for electricity, it is preferable to use utility power for charging only during non-peak hours. Charger block can prevent utility power from being used for battery charging during peak billing periods. During the time period set between Charge Block Start and Charge Block Stop, AC1 (Grid) input continues to be passed through to the loads. Inverter operation remains unaffected during the charger block period. During the charger block period, no charging on AC1 occurs even if the batteries discharge below Recharge Voltage/SoC setting. However, a generator connected to AC2 (in the absence of utility/AC1 power) or a Conext MPPT solar charge controller may charge batteries during the charger block period. AC priority must be set to AC2 to charge batteries with a generator connected to AC2 during the charger block period. If the charger is operating (that is, in float, absorption, bulk, or equalize stage) at the Charge Block Start time, charging on AC1 stops immediately and the charger enters an idle state identical to no float (see "Charger Settings" on page 57). When the charger block period is over, the charger does not resume the charge stage that was interrupted. Instead, if the batteries are above the Recharge Voltage/SoC setting, the charger remains idle. If the battery voltage discharges below the Recharge Voltage/SoC setting during the charger block period, the XW Pro begins a new charge cycle with the bulk stage after the charger block period has expired (at the Charge Block Stop time). For example, charger block is set to start at 5:00 PM and end at 8:00 PM. If the XW Pro is charging from AC1, charging stops at 5:00. When charger block ends at 8:00, the XW Pro does not automatically resume charging. The unit first measures the battery voltage. n If the voltage is below the Recharge Voltage setting, or if the state of charge is below Recharge SoC, then the XW Pro starts a new charge cycle from bulk. n If the voltage is above the Recharge Voltage setting, or if the state of charge is above Recharge SoC, then the XW Pro remains idle and continues passing through AC to the loads. The XW Pro also keeps measuring the battery voltage as before to determine whether to start a new charge cycle. Peak Load Shaving (PLS) Many utilities impose a surcharge on their customers based on the peak load used by a facility. To reduce utility peak demand charges, the inverter can be configured (using the Load Shave Amps setting) to help limit the maximum draw the AC loads place on the utility. The inverter can be programmed to provide power above a specified level to avoid the surcharge. When the utility current draw reaches the maximum level, the inverter assists by sourcing power from the batteries to the loads. 990-91402B This document is intended for use by qualified personnel 95 XW Pro Owner's Guide Configuration Time-of-Use Metering For PLS to be effective, all loads must be connected to the inverter. For large loads, multiple (or stacked) inverters may be required. To help the batteries supplement the power requirements of the connected load, an additional source of power (solar, wind, or hydroelectric) is recommended. The default PLS setting for Time in Float is zero. In this case, PLS is only entered/exited as programmed within the time window. When the Time in Float is different than zero, PLS shall start only if the battery amperage remained at the specified level for the configured time. Example Settings Load Shave=Enabled, Load Shave Amps=10 A, LoadShaveStart=6:00pm, LoadShaveStop=9:00pm, Time in Float=60 min, Peak Load Shave Delay = Enabled. With these example settings, the XW Pro would enter PLS within the configured window of time only if the battery was charged from MPPT in Float (including Absorption) for 2 hours. NOTE: When actively operating, the XW Pro compensates for active power as a reference for controlling the total current as specified in the Load Shave Amps setting. However, there is also reactive power that is not compensated for by the XW Pro. For example, if Load Shave Amps is set to 10A, the inverter will only start drawing power from the batteries at a current level which would measure approximately 11A which is 1A higher than the Load Shave Amps value to meet the demand of the loads. Utilities use time-of-use metering to determine utility charges during peak usage hours and to impose a surcharge. The XW Pro can be configured (using the Load Shave Start, Load Shave Stop and Charger Block settings) to overcome these peak charges by using utility power to charge the battery bank during the inexpensive energy hours and consuming the battery energy during expensive energy hours. For example, if Charger Block is set between 9:00 AM and 10:00 PM and Load Shave is set between 6:00 PM and 9:00 PM, charging on AC1 stops at 9:00 AM and continues to pass through utility AC to the loads. If charging is required during the charger block period, and AC Priority is set to AC2, the XW Pro can use any AC source connected to AC2. Loads will transfer to the AC source on AC2 as well.The inverter connects to the utility grid at 6:00 PM and supports loads using the batteries. The inverter continues to run until 9:00 PM. The XW Pro then stops supporting the utility grid and passes utility AC through to the loads. At 10:00 PM utility AC begins maintaining the batteries based on the battery charger settings. The above example allows an external renewable energy source to be utilized as a primary charging source during a desired time window. The charger (using utility AC connected to AC1) can then be used to supplement the battery charging when the utility rates are low. 96 This document is intended for use by qualified personnel 990-91402B Configuration Self-Consumption XW Pro Owner's Guide When using the system for time-of-use metering, the system should be designed with a battery capacity large enough to support loads during the entire peak rate period without reaching the Low Battery Cut Out or Low Battery Cut Out SoC setting. NOTE: If the batteries reach the Low Battery Cut Out setting, the XW Pro automatically reconnects to the utility grid to maintain the connected load. PLS can also be used with time-of-use metering to support self-consumption. In the selfconsumption mode of operation, the XW Pro delays Peak Load Shave mode by a fixed time of 2 hours. This is done by allowing a priority for the MPPT solar charge controller to charge the battery bank. This configuration can be selected under the XW Pro menu by setting Peak Load Shaving Delay under Advanced Features to Enabled. The default setting for is Disabled. 990-91402B This document is intended for use by qualified personnel 97 XW Pro Owner's Guide Configuration Managing Firmware The firmware running on the XW Pro can be upgraded under the Firmware tab in the XW Pro menus.

Contact Customer Service for further assistance. Please be prepared to describe details of your system installation and provide the model and serial number of the unit. See beginning of document for contact information. 114 This document is intended for use by qualified personnel 990-91402B Troubleshooting XW Pro Owner's Guide Inverter Applications The XW Pro performs differently depending on the AC loads connected to it. If you are having problems with any of your loads, read this section. Resistive Loads Resistive loads are the easiest and most efficient to drive. Voltage and current are in phase, which means they are in step with one another. Resistive loads generate heat in order to accomplish their tasks. Toasters, coffee pots, and incandescent lights are typical resistive loads. It is usually impractical to run larger resistive loads--such as electric stoves and water heaters--from an inverter due to their high current requirements. Even though the inverter may be able to accommodate the load, the size of battery bank will limit inverter run time. Motor Loads Induction motors (AC motors without brushes) require up to six times their running current on startup. The most demanding are those that start under load (for example, compressors and pumps). Of the capacitor start motors (typical in tools such as drill presses and band saws), the largest you can expect to run is 1 horsepower. Universal motors are generally easier to start. Check that the Locked Rotor Amps (LRA) rating of the motor load does not exceed the maximum surge current rating of the inverter. Since motor characteristics vary, only testing will determine whether a specific load can be started and how long it can be run. If a motor fails to start within a few seconds or loses power after running for a time, it should be turned off. When the inverter attempts to start a load that is greater than it can handle, the inverter may shut down from an AC overload fault. Problem Loads Very Small Loads If the power consumed by a device is less than the threshold of the search mode circuitry, and search mode is enabled, the inverter will not run. Most likely the solution will be to disable Search mode or lower the sense threshold (see "Inverter Settings" on page 53). Fluorescent Lights and Power Supplies Some devices cannot be detected when scanned by search mode circuitry. Small fluorescent lights are the most common example. Some computers and sophisticated electronics have power supplies that do not present a load until line voltage is available. When this occurs, each unit waits for the other to begin. To drive these loads, either a small companion load like a light bulb rated for more than the Search Watts setting must be used to bring the inverter out of search mode, or the inverter may be programmed to remain on by disabling search mode (see "Inverter Settings" on page 53). 990-91402B This document is intended for use by qualified personnel 115 XW Pro Owner's Guide Clocks Searching Troubleshooting You may notice that your clocks are not accurate. Some of the clocks on your appliances may reset when the XW Pro is in search mode. Disabling search mode will resolve this issue (see "Inverter Settings" on page 53). When the inverter is in search mode, it may fail to start some loads even though the rated wattage on the load is more than the Maximum Search Watts setting. Disable search or apply an additional load (companion load) to make the inverter exit search mode. 116 This document is intended for use by qualified personnel 990-91402B Troubleshooting XW Pro Owner's Guide Inverter Troubleshooting To determine the cause of an inverter error condition, refer to the troubleshooting table below for possible solutions.

Turn XW Pro off and on to resume normal operation. Fault Messages Fault Types When the XW Pro detects a fault condition, the fault is displayed within the the Conext Gateway web application. The XW Pro also illuminates the Event/Warning LED on the inverter information panel. A fault affects the operation of the unit. See Table 24 on page 125 for an explanation of the different fault types. You can access all past fault messages for a device in the Conext Gateway web application by navigating to Events > Historical Events in the XW Pro status page. There are three types of fault messages: automatic faults, manual faults, and escalating automatic faults. Table 24 describes how they differ in their behavior and how you can respond to them when they appear on the Conext Gateway. Table 24 Fault Types and Behaviors Fault type Behavior Automatic faults Clear automatically if the fault condition that generated the message goes away. You can also acknowledge automatic faults without waiting for them to clear automatically. It is not possible to clear a fault if the cause of the fault is still present. 990-91402B This document is intended for use by qualified personnel 125 XW Pro Owner's Guide Troubleshooting Fault type Behavior Require you to clear them by: Manual faults n selecting Clear Faults on the Main XW Pro menu or on the menu for the Xanbus-enabled device that generated the fault (if the fault condition still exists, the fault message reappears). n correcting the condition that caused the fault. Clear automatically if the fault condition goes away, just like an automatic fault. However, if an escalating automatic fault occurs several times Escalating automatic faults within a defined time period, the escalating automatic fault becomes a manual fault, requiring user intervention. For example, if an AC Overload fault occurs three times in five minutes, it will no longer clear itself and become a manual fault. Then you must identify the problem, correct the fault condition, and clear the fault. Inverter Operation After Faults XW Pro operation changes when a fault occurs. How the operation changes depends on the operating state of the unit when the fault occurred--inverting, charging, grid or generator support, AC bypass, and so on--and on which fault has occurred. Table 25 Inverter Operation After Faults Faults State when Faults Occur Action After Faults F1, F2: AC Output Inverting Unit stops inverting and waits for nominal AC output voltage level, or a manual clear from user. F17 to F22: Relay Welded Inverting Unit stops inverting and waits for user to clear fault. F23 to F40: Anti-Islanding Grid Support (Peak Load Shaving or Selling) Unit moves to AC bypass and waits for nominal grid conditions to return for a minimum of five minutes.

If inverting, the unit shuts down and waits for the temperature to return to nominal value. If in any of the AC-interactive states (charging, peak load shaving, sell, gen support), the unit goes into AC bypass mode until the temperature returns to the nominal value. If the unit is not in AC bypass, it shuts down until the temperature returns to nominal value. After these faults clear, the unit returns to its previous operating state. F47 to F49: DC Under Voltage and Over Voltage Unit is inverting or has qualified AC input and is preparing to charge. If inverting, the unit shuts down and waits for nominal voltage. If operating with a qualified AC source, the unit charges if charging is enabled, or remains in AC bypass if charging is disabled.

DISCLAIMER REGARDING STATUS DATA Status data reported by the XW Pro are approximate values intended to provide general and non-exact information about the XW Pro. Under no circumstances should this status data be used for precise evaluation of the XW Pro system performance, including efficiency considerations. In systems with a single XW Pro, the measurement capabilities of the inverter/charger allow for deviations of up to 5% of actual values. In systems with multiple inverter/charger units, the compounded effect of accuracy deviations in the status data could result in aggregated deviations exceeding 5% of actual values. For systems requiring higher accuracy status reporting of ac parameters, Schneider Electric recommends the use of external monitoring equipment of appropriate and accurate calibration. For higher accuracy measurement of dc (battery) parameters, Schneider Electric recommends installing an appropriate dc battery monitor in the system.
