This is what we call 'self-consumption'. zappi is a Mode 3 charging station, compatible with all electric vehicles that comply with SAE J1772, EN62196 and EN61851 plug-in electric vehicle standards. zappi works like any regular charging point but has special eco charging modes which will benefit homeowners with grid-tied microgeneration systems, like wind or solar generation. Two special ECO charging modes automatically adjust charging current in response to on-site generation and household power consumption. In FAST charge mode, zappi operates like an ordinary EV charging. A grid current sensor (supplied) simply clips around the incoming supply cable. This sensor is used to monitor excess power and when using the special ECO charge modes, zappi automatically adjusts the charge rate in response to available surplus. Feature Set � Available with Type 1 or Type 2 connector � 3 charging modes: ECO, ECO+ & FAST � Optimises microgeneration self-consumption � Works with solar PV or wind turbine systems � Economy tariff sense input � Programmable timer function � Charge and event logging � Remote control and monitoring add-on option � Pin-code lock function � Tap operated display backlight � Built-in RCD protection � Integral cable holster � Supplied with clip-on grid current sensor Overview Diagram The diagram over the page, shows the zappi as part of a complete energy management system.

Waiting for EV... Charge Delayed Paused... Charging 10 zappi The EV is not connected to zappi In this example the last charging session delivered 20.8kWh of energy to the EV and 80% of that energy came from the solar panels. zappi is waiting for sufficient surplus power from the microgeneration system. This screen will be shown in ECO+ mode as it's only in this mode that charging will stop if there is not enough surplus power. The house in the centre is straight-faced as grid electricity is being used by the house (0.9kW is this example). zappi is waiting for the EV to respond; the EV is not ready to accept charge. The charging session has been delayed by the EV because a schedule charge has been set in the vehicle. zappi is paused for a few seconds in order to limit the start/stop frequency during ECO+ mode charging. The Start/Stop Delay can be changed in the Charge Settings/ECO+ Settings menu option. The EV is charging. In this example the car is charging in ECO+ mode at 1.6kW, there is no import or export from the grid (0.0kW) and the EV battery has charged by 8.9kWh since the car started. operation and installation manual Charge Complete Restart... Operation The EV is fully charged. The charge energy used during the last charge is displayed at the bottom right (20.0kWh in this case) and the 'green contribution' is also shown (40% in this example). Zappi is doing a restart sequence. This may happen with some EVs that need to be 'woken-up' to start charging after a pausing charge. Charge should start immediately afterwards, otherwise the "Charge Delayed" message will appear. operation and installation manual zappi 11 Operation Charging Modes zappi has three different charging modes which can be selected simply by pressing the showing. The charge mode can be changed before or during a charge. button when the main screen is FAST ECO ECO+ Regardless of the charge mode used, all of the surplus electricity is used but zappi's special eco charge modes, limit the amount of grid electric used. Below is explanation of each of the three charging modes. FAST Charges at the fastest rate. Fast Mode will charge the EV at the fastest rate and will import grid electricity if there is insufficient surplus generated power. The actual charge rate is dependant on the EV's onboard charger and the grid supply voltage. Typically, vehicles have either a 3.3kW or 6.6kW charger. The actual power can be a little different if the grid supply voltage is not exactly 230V. zappi will deliver up to 7kW provided the supply connection is suitably rated. ECO Adjusts the charge rate to limit the use of grid electricity. The charge rate is continuously adjusted, in response to changes in generation or power consumption elsewhere in the home, thereby minimising the use of grid power. Charging will continue until the vehicle is fully charged, using available surplus power. However, if at any time, the available surplus power falls below 1.4kW, the shortfall will be drawn from the grid. Note: The EV charging standard does not support charging below 1.4kW. ECO+ Adjusts the charge rate to limit the use of grid electricity and will pause the charge if there is too much grid electricity being used. The charge rate is continuously adjusted, in response to changes in generation or power consumption elsewhere in the home, thereby minimising the use of grid power. Charging will pause if there is too much imported power, continuing only when there is enough surplus power available. The surplus power threshold at which the charge will start or stop can be set in the ECO+ Settings option, which is found in the Charge Settings menu. It is possible to charge the EV using only surplus renewable power, providing there is sufficient surplus power to do so. To do this, set the Min Green Level to 100%. The Min Green Level is the minimum level for the contribution of green energy at the end of the charge. The actual green contribution for the charge, is displayed when the charge is complete or the EV is disconnected. For example: With Min Green Level set to 50%, charging will be paused if 700W of power is being imported from the grid and will resume charging when there is 700W of power being exported. Note: The EV charging standard does not support charging below 1.4kW. 12 zappi operation and installation manual Operation Manual Boost The Manual Boost function can only be used when charging in ECO or ECO+ mode. When boosting, the charge rate is set to maximum (just like FAST mode), until a set amount of energy has been stored in the EV's battery. After which, zappi will revert back to ECO or ECO+ mode. This function is useful if you arrive home with an almost flat battery and would like to charge the vehicle immediately to ensure there is enough charge for a short trip if needed. The amount of energy (kWh s) the boost uses can be changed in the Charge Settings/Boost menu. When in ECO or ECO+ mode, each press of the button will cycle through the boost options as illustrated below: Boost Smart Boost Cancel Boost Activating Boost 1. When charging in ECO or ECO+ mode, press until BOOST is shown. 2. The boost will start after a couple of seconds and the display will show the remaining boost energy. The boost duration can be altered (when a boost is not in progress) in the Charge Settings/Manual Boost menu option. Cancelling Boost The boost can be cancelled by pressing until Cancel Boost is shown. operation and installation manual zappi 13 Operation Smart Boost The Smart Boost function will charge the EV with a minimum kWh figure by a set time. Smart Boost is available only in ECO and ECO+ modes. The Smart Boost function does not bring the battery to a certain state of charge. The target kWh is only the energy added during the charging session. When in ECO or ECO+ mode, each press of the button will cycle through the boost options as illustrated below: Boost Smart Boost Cancel Boost Example: It's a sunny Sunday and you wish to ensure there is enough charge in the EV to get to work in the morning (e.g. 15kWh), but in the meantime, you want to use the surplus energy from the PV system to charge the car, so you choose to use ECO+ mode. At sunset there was only 10kWh of charge accumulated. However, because you activated Smart Boost, and set the time you needed to leave for work, zappi automatically boosted the charge in the night to top up the battery to the required 15kWh by 7am. Activating Smart Boost 1. When charging in ECO or ECO+ mode, press until SMART BOOST is shown. 2. The SMART BOOST icon will show including the set energy amount in kWh s and the target time, (17kWh s and 7am respectively, in this example screen shot). 3. zappi will then test the EV for a few seconds, to determine the maximum charge rate. 4. The boost will start at the latest possible time to achieve the set energy amount, if the current charge session has already accumulated enough energy, the boost will not be required and so will not operate. The required energy and target time can be altered only when Smart Boost is not active. Theses settings are in the Charge Settings/Smart Boost menu option. 14 zappi operation and installation manual Operation Boost Timer When using ECO or ECO+ charge modes, zappi can be programmed to 'boost' the current charge at certain times. When boosting, the charge rate is set to maximum (just like FAST mode), regardless of the amount of available surplus power. This means that power may be drawn from the mains grid supply during boost times. � There are four editable time slots which can be set to operate for certain days of the week. � Setting the duration to 0h00 will make the boost inactive. Programming Boost Times 1. From the main screen, press or to enter Main Menu 2. Select Boost Timer from within the Charge Settings menu. The BOOST TIMER screen is then shown. 3. The boost can now be edited: Use or buttons to highlight the time slot you wish to change. The screen below shows the start hour being edited: 4. Alter the start hour with the or buttons and then press to move to minutes. 5. Edit the duration in the same way and then press again to edit the days of the week you want the boost to be active for; each day of the week and by toggled on/off with or buttons, press to go to the next day. Pressing on the last day (Sunday) will confirm the boost time slot and whole line will be highlighted again. 6. Press to exit the BOOST TIMER screen. Economy Tariff Boosting Boosting only when economy rate electricity is available can be achieved in one of three ways: 1. By setting the boost timer to coincide with the economy tariff times. This option should be used only if the electricity meter is a dual-rate meter (modern meters usually are). 2. Boost only at set times AND if economy rate electric is available. 3. Automatically boost whenever the economy tariff rate electricity is available, regardless of boost times* *Options 2 and 3 are available only when using the eSense input. For option 1, the eSense Input in the Advanced menu should be set to Boost Timer Enable. With the Boost Timer Enable function set, the BOOST TIMER screen will include an extra column (see screenshot). The e can be toggled on/off, if e is present, the boost will activate only when the boost times are valid and the economy rate tariff is available. Alternatively the eSense input can be used to active the boost whenever the economy tariff rate electricity is available, regardless of boost times (option 2). To do this, the eSense Input option in the Advanced menu should be set to Boost. When using this option, the Boost Timer is not needed. Boost Time Conflicts If one or more boost times conflict, the boost will follow the latest time or longest duration. operation and installation manual zappi 15 Operation Lock Function zappi can be locked from unauthorised operation. The Lock Function requires a pin number to be entered before the unit can be operated. The lock can be set to be active only when the EV is plugged in or only when unplugged, it can also be set to be always active. The settings for the Lock Function can be found in the Other Settings/Lock Function menu option.

Time & Date The date and time are used for the Boost Timer and the savings calculations and therefore should be set correctly. In the event of a power-cut, zappi will still keep track of the time and date for a few days, so when power is restored the clock will not need to be reset. Time is always in 24-hour format but the date format can be changed. zappi will automatically adjust the clock for Daylight Savings Time (DST) as long as Auto DST is enabled and the correct time zone is selected. Icons The heater icons shown on the main screen can be individually set for both heater outputs. This gives an installation specific, graphical representation which heater is active. For example; Heater 1 could be a hot water cylinder and Heater 2 could be a radiator. This function can be accessed via the Settings/Display/Icons menu. As well as being able to customise the heater icons, it's also possible to change the generation type from solar to wind. Advanced Settings The Advanced Settings menu is passcode protected. The default passcode is 0 0 0 0 although it can be changed with the Passcode menu option. Supply Grid - Phase The Phase setting is only used installing the zappi on 3-phase supplies. It should be set to match the phase number that the zappi is wired to so that the power measurements are correct and that the zappi responds to the correct phase when using the harvi wireless sensor. See Three-Phase Systems (page 32) and Supply Grid � Net Phases (page 22) for more information. Supply Grid � Device Limit Sets the maximum current that the zappi will draw (including when boosting and FAST mode). This is useful if the supply current is limited, like a 16A rather than 32A. Supply Grid � Grid Limit Sets the limit that can be drawn from the grid connection (i.e. the maximum import current or the main fuse rating). Example: A property may have a grid supply limit of only 65A, several appliances are on and the property is consuming 12kW (52A) by other appliances and the user wants to charge in FAST mode. Without the Grid Limit set, the total consumption would exceed the allowed import current. However, with a Grid Limit setting of 60A, zappi would temporarily limit the charging current to 8A (about 1.8kW) and the maximum allowed import current would not be exceeded. Supply Grid � Battery If the property has a static AC battery system installed, it's possible to get the zappi to work in harmony with the system, provided a CT has been installed to monitor the battery inverter. See Battery Storage Systems (page 32) for more information about battery storage systems. The table below details the different settings for working with an AC coupled battery storage system: operation and installation manual zappi 21 Configuration Setting None Limit to Gen Avoid Drain Avoid Charge Avoid Both Function description There is no battery system installed. Will limit the output of the zappi (except when boosting), to prevent unwanted draining a AC coupled battery system. This setting does not require a CT to monitor the battery, but does need a CT to monitor the solar/wind generation. Note: This setting is to support legacy installations � it is preferable to install a CT to monitor the battery and use one of the settings below. Stops the zappi (or other linked myenergi devices) draining the battery when using surplus power from the solar or wind generator. Effectively allows the zappi (or other linked myenergi devices) to take priority over the battery when charging from solar or wind generation. Provides both of the above functions. Supply Grid � Net Phases When enabled, all readings from 3-phase myenergi devices and harvi units configured as 3-phase, will be netted. This means that surplus generation on ANY phase will be considered be available for consumption on ANY other phase. See Three-Phase Systems (page 32) for more details about myenergi devices on 3-phase supplies. Supply Grid � Export Margin This sets a minimum level of export power which is maintained when zappi is charging in ECO or ECO+ modes. Normally Export Margin would be set to 0W (zero Watts) and all of the available surplus will be used to charge the vehicle, however, it is may be desired to have a minimum export level at all times. CT Config The CT1 and CT2 inputs are configured depending on the connected CT sensors. The internal CT which measures the output current also has some settings. Note: These settings are the same when using CTs with the harvi device, however, they are set via the Linked Devices menu rather than the CT Config menu. Important: There must by only one Grid CT set (per phase) for the whole installation. CT CTIL CT1 CT2 Description This is the internal CT which measures the output (charging) current of the zappi. CT1 input. CT2 input. CT Type None Grid Generation Only Storage Only Gen & Battery Description No CT connected. Grid CT monitors the import and export power of the property, this is main control CT and there must only be one Grid CT set for each phase. Monitors Solar PV or Wind generation. Monitors a device that can 'store' energy (e.g. a third-party energy diverter) and enables the zappi to take priority over it. The power used by the third-party device is considered as surplus power unless the device is intentionally using grid power (i.e. it is boosting). The CT should be installed on the Live supply cable feeding the diverter, with the arrow pointing away from it. Monitors Solar PV or Wind generation that is combined with a DC-coupled battery. 22 zappi operation and installation manual Configuration Monitor AC Battery Monitors any load, for example a washing machine or the lighting circuit. This setting can also be used to limit current drawn by myenergi devices on a particular circuit which includes other loads. See Load Balancing / Current Limiting (page 32) for more details. Used to monitor an AC-coupled battery. With this setting it's possible to manage the distribution of surplus energy between the battery and the zappi (including myenergi devices). The Battery setting in the Supply Grid menu is used to configure how the zappi will operate alongside the battery system. See Battery Storage Systems (page 32) for more information. The CT should be installed on the Live supply cable of the battery inverter/charger, with the arrow pointing away from it. CT Groups CTs can be put in groups so that their readings are netted. For example, you might want to monitor two solar PV systems and see the total generation on the display. Use Group in the CT Config menu to set which group the CT should be in. Note: Different CT Types cannot be in the same group, the group names make this clear. Only the first 4 groups can be used for current limiting, see Group Limits below. Group Limits Current limits can be set for certain CT Groups. When a Group Limit is set the myenergi devices in the group will limit the power they draw to keep within the set limit. Group limits should be set only on the master device. See Linking Devices (p24) for details about master devices. It is possible to use more than one group limit type (e.g. IL1 with MN1, so that there are two conditions for limiting). Group Limit example Limit current drawn by two zappi devices that are on the same 32A supply. Additional CT installed None; only the internal CTs are used. Limit current drawn by an zappi device One CT is clipped around Live of the 40A supply and wired that is fed from a 32A supply which is to CT2 of the zappi. also feeding another appliance (e.g. a tumble dryer). Limit current drawn by two zappi devices that are in a garage which is fed from a 40A supply. A washing machine and dyer are also in the garage. One CT is clipped around Live of the 40A supply to the garage and wired to CT2 of one of the zappi units. Note: The other zappi does not need a to have a CT connected, but it will still need to have a CT input configured to be in the same Monitor group.

By linking devices, you can use more of your own energy or have more control and visibility. Devices available now (or soon to be available) are: zappi � An eco-smart electric vehicle charge point that can use surplus power to charge the car. harvi � A self-powered wireless sensor that can be used along with myenergi load controlling devices such as eddi and zappi. It is able to detect grid import/export conditions as well as generation power and send this information wirelessly to devices such as the eddi or zappi, this can greatly simplify installation. hub � The link between your myenegi devices and the internet, allowing remote monitoring and control via a mobile App. Master & Slave Devices When two or more myenergi devices are wirelessly linked, one device will act as the 'master' device. This device will control the other 'slave' devices. Some settings can only be changed on the master device, e.g. Grid Limit and Net Phases. Use the Set Master function in the Advanced Settings/Linked Devices menu to set which device should be master. It's a good idea to choose the device that is the most convenient to access should you wish to change settings. Pairing Devices Devices are 'paired' by selecting Pairing Mode on each device (one device must be set to master). 1. On the slave unit, select Pairing Mode from the Advanced Settings/Linked Devices menu or by pressing the pair button if the device is a harvi or hub. 2. Now select Pairing Mode on the master device. 3. You will now see the SEARCHING FOR SLAVES screen and zappi will be searching for other devices which are on the same channel and are in Pairing Mode. Any devices found are listed along with their unique serial numbers. 4. Select the device you want to add by highlighting the appropriate device using the and pressing The device will then be added and the screen will return to the previous menu. buttons and then 5. The DEVICES screen will then show, listing all the devices in the network. The recently added device will be able to be configured after the UPDATING message disappears. Channels On rare occasions it is possible that there are other appliances operating on the same frequency which could cause interference. If it is not possible to link devices or the connection seems poor, changing the RF Channel may help. To do this make sure all devices are removed from the network by selecting Reset Settings in the Linked Devices menu and then select a different channel with the Channel menu option. Be sure to change the channel on the other devices before attempting to link them. Removing Devices A device can be removed by selecting it from the Devices menu and then selecting Remove Device. Device Settings Most device types have settings which can only be changed via the Linked Devices menu. For example, eddi and zappi have a settings for priority and harvi has settings to configure its CT inputs (see Device Priorities page 25). The device settings are accessed through the Linked Devices menu; select Devices then select the appropriate device and press to bring up the devices' settings screen. Refer to the relevant devices' instruction document for more information regarding the actual device settings. Note: After a device has been paired you will have to wait a few seconds for the device to update before the settings can be accessed, the screen will show DEVICES UPDATING when this is happening. 24 zappi operation and installation manual Configuration Device Priorities The priority of each, load controlling linked device, can be set from any device with a display. This enables control of how the surplus energy is shared between them. The example below shows one eddi device, two zappi devices and one harvi on the same 'network'. 1 2 4 3 5 All linked devices 1 are listed in the DEVICES screen, the device shown in CAPITAL letters is the device currently being viewed. The serial number of each device is shown on the right 2 The priority is shown on the left of each load controlling device 3 with 1 being the highest priority. If two or more devices have equal priority, the available surplus (for that priority level) is shared equally between them. The ~ symbol 4 indicates which device is the 'master' device which has the Grid Sensor connected to it. If the ? symbol 5 is shown along side a device, it indicates that communication has been lost from the device. Linked Devices Information The current status of all linked devices, can be viewed together in the LINKED DEVICES INFO screen which can be found from the Main Menu. 1 2 4 3 This screen lists all the linked devices 1 and the priority setting for each device 3 The current device is shown in CAPITAL letters.

For example, the Grid connection point, the solar/wind inverter or a static battery system. Installation of a CT to monitor the Grid connection point is required. Other CTs are optional and can be purchased separately. The number and location of CTs used within an installation will vary according to devices installed and the user requirements. CTs can be wired to any myenergi device with CT inputs (e.g. eddi, zappi or harvi). This enables very flexible installation as the CT can be wired to the nearest device. Note: The harvi device can be used if it is not practical to connect any CT to the eddi or zappi. Once installed the CTs need to be configured, see CT Config (p22) for details of how to configure the CTs. Grid CT The Grid CT sensor (supplied) needs to be clipped around either the Live or Neutral meter tail of the electricity supply meter. If using the Neutral conductor, reverse the direction of the sensor (so the arrow is reversed). The positioning of the Grid CT sensor is crucial, take note of the following when deciding where best to install the sensor: Can be connected to any myenergi device with a CT input e.g. the eddi or zappi (wired sensor) or harvi (wireless sensor). ALL of the import and exported power must be 'seen' by the sensor � be sure to install it upstream of ANY junction box or 'Henley Block' (the CT can be fitted inside the consumer unit). There must be only one Grid CT per-phase for the whole installation. (There can be other CTs but only one at the grid connection point, also note CTs for third-party devices do not matter). The CT should be on the Live or Neutral cable. The arrow on the bottom of the CT sensor must be pointing towards the consumer unit (in the direction of grid import) if on the Live cable, or reversed if on the Neutral cable. ELECTRICITY METER GRID SENSOR CONSUMER UNIT Ensure the CT is fully closed and clicks shut. Be sure to wire the CT the correct way round; black [�], red [+] otherwise import and export readings will be swapped. Reverse if on Neutral cable Additional CTs There is an option to add other CT sensors (available separately) for monitoring the generation or other appliances such as battery systems or general loads. Installing a CT for the generator (PV system) will allow the main screen to show the generated power and the total power consumption of the all the other appliances in the property. CTs can also be used to limit the power drawn form the supply. See Load Balancing / Current Limiting p32. Additional CTs Can be connected to any myenergi device with a CT input that is linked to the network (see Linking Devices p24). The arrow on the bottom of the sensor must be pointing in the direction of normal power flow (e.g. away from the PV inverter) if on the Live cable or reversed if on the Neutral cable. Ensure the sensor is fully closed and clicks shut. Be sure to wire the CT the correct way round; black [�], red [+]. 30 zappi operation and installation manual Installation Extending the sensor cable If there is a need to extend the sensor cable, twisted-pair cable like CAT5 or telephone cable must be used. DO NOT use mains cable, bell wire or speaker cable. It is important to use only twisted-pair cable to maintain signal integrity. The cable can be extended up to 100m. Wireless CT Sensor (optional accessory) In some cases it can be difficult or impractical to install a wired sensor. For example it may be the case that the zappi unit needs to be connected to a sub-board, rather than main consumer unit and two consumer units are in different buildings. The solution to is to install harvi � a clever little device that enables the zappi and eddi products to be installed without using wired CT sensors for measuring the grid and or generation power; instead the CT sensor is connected to harvi. The harvi does not need batteries or a power supply � the energy from the sensor is harvested and used to transmit the measurement signal to the zappi or eddi. This means batteries or electrical wiring are eliminated! Up to 3 CT sensors may be used with harvi and it also supports 3-phase systems if three sensors are connected. Refer to the harvi installation guide for details on installing and configuring harvi for your system. CT Golden Rules Grid CT � Only ONE Grid CT per phase (check for only one ~ symbol in Linked Devices Info). � Located to `see' ALL import and ALL export current (i.e. always upstream of any junction box). � Arrow pointing in direction of import (e.g. towards consumer unit if on Live cable). � Must be on the same phase as the Master myenergi device. All other CTs � Arrow should point towards the consumer unit. 3-Phase harvi CTs � When using harvi in 3-phase mode, the CT inputs correspond to the phase number (e.g. CT1 = Phase 1). CT can dos Can be wired to ANY myenergi device in the network. harvi can be used to make ANY CT wireless. Cable can be extended up to 100m (must use twisted-pair cable e.g. one pair of CAT5). Cable can be shortened. Can be clipped around two or more conductors feeding appliances of the same type (e.g. two Live cables from two inverters that are on the same phase). Can be in close proximity to other CTs. Wires can be swapped around in device to reverse the direction of the readings (e.g. change import to export). Can be grouped with other CTs of the same type so that the power reading is summed (e.g. east and west solar Generation). Can be used on the Neutral conductor (direction of arrow or wires must be reversed). Can be set to None if you want to exclude the reading. operation and installation manual zappi 31 Installation Advanced Installation Options Load Balancing / Current Limiting CTs can be also used to the limit current drawn by myenergi devices to avoid overloading circuits. this is sometimes referred to as load balancing. There are four different ways to limit current and they can be used alone or combined for more complex situations. See the table below: Function Device Limit Grid Limit Group Limit (internal CT) Group Limit (with external CT) Operation Example Sets a maximum current that can be drawn by the device (e.g. zappi). The current will not be exceeded even during Boost or Fast charge. A zappi is wired to a 20A supply (rather than a 32A). The maximum current drawn will not exceed the set limit (e.g. 20A). Sets the limit that can be drawn from the grid connection (i.e. the maximum import current). The zappi and any other linked myenergi device, will limit the current they draw if there is a danger of exceeding the set Grid Limit. A property may have a grid supply limit of only 65A, several appliances are on and the property is consuming 12kW (52A) by other appliances and the user wants to charge in FAST mode. With a Grid Limit setting of 60A, zappi would temporarily limit the charging current to 8A (about 1.8kW) and the maximum allowed import current would not be exceeded. Sets the combined current limit for several myenergi devices. A property has a large PV array and a swimming pool, three eddi units are installed to heat the pool with surplus solar power using 3kW heaters. The supply for the eddi units is only 40A, to be safe a Group Limit of 35A is set. Sets the combined current limit for several myenergi devices that are sharing a supply with another large appliance. An eddi is installed to heat the hot water cylinder in a garage which also has a washer and a dryer (2.5kW each), the garage has a supply of only 32A coming from the main consumer unit in the house. If all appliances were on and there was no limiting set, the total current would exceed the maximum supply current. Three-Phase Systems If the installation supply is three-phase, it is recommend to install a harvi device and use three Grid CTs (one for each phase). This will allow the zappi to show the total grid import and export figures rather than just one of the phases. If all three phases are monitored and the generation is 3-phase, it is also possible to net the export power across phases, to do this, enable Net Phases in the Supply Grid menu see Supply Grid � Net Phases (p22). This allows the zappi to use surplus power from any phase and not just the phase which the zappi is installed on. However, you must be sure that the electricity is metered in such a way as to allow this. Battery Storage Systems AC coupled Where there is an AC coupled battery storage system, there can be a conflict as both the storage system and the zappi are effectively competing to consume the surplus energy. Whilst this is not necessarily an issue, the results can be somewhat unpredictable. There is the option to add an additional CT sensor to monitor the battery storage; this will give control as to which device has priority. This additional CT sensor should be wired to one of the CT terminals of the zappi or a harvi device if wireless measurement is required. This CT should be clipped around the live or neutral cable of battery inverter. During the setup process it will be necessary to change the setting for the appropriate CT to AC Battery; refer to CT Config (page 22) . Also refer to Supply Grid � Battery (page 21). for information on setting 'priority' of battery systems. 32 zappi operation and installation manual Installation DC coupled Battery systems that charge directly from the solar array and cannot change from AC are usually referred to as being DC coupled. This type of battery system uses the solar PV inverter to provide power from the batteries, thus it is not possible to differentiate between solar and battery power when using a CT to measure the AC current from the inverter. Because of this limitation, there are less options for managing the surplus power with this type of battery system. However it is usually possible to effectively give priority to battery by setting an Export Margin in the zappi. A setting of 50W or 100W is recommend. The Export Margin setting is found in the Advanced Settings/Supply Grid menu. Third-Party Diverters Some properties may have a third-party energy diverter installed and you may want the zappi to take priority (when consuming surplus power) over the diverter. This is possible by installing an extra CT to monitor the diverter. The CT should be clipped around the Live cable of the supply feeding the diverter. The arrow on the CT should be pointing away from the diverter. Wire the CT to the nearest myenergi device or use a harvi unit wireless connection is needed. Configure the CT Type as Storage Only. See CT Config (page 22) for details of how to configure CTs. Voltage Optimisers If there is a voltage optimiser (VO) installed in the property, the CT sensor and the zappi must both be on the same side of the VO; either the incoming grid supply or the optimised supply. operation and installation manual zappi 33 Installation eSense Input (economy tariff) zappi has an input which can be used to sense the availability of economy tariff electricity, this can be used to automatically boost the charge when in ECO or ECO+ charging modes. The eSENSE input is electrically isolated and effectively draws no current so the cable size is not important. An AC voltage between 100V and 260V across the L and N terminals of the eSENSE input cause the economy tariff symbol to be shown on the main screen. The eSENSE Earth terminal is not required to be connected. See eSense Input on page 23 for details of how to configure the eSENSE input. 34 zappi operation and installation manual Installation Fitting the Cover 1. Refit the cover and secure with ALL twelve of the M4 screws. It is best to screw these by going around in sequence shown without skipping any holes. 2. Slot the white cover down onto the unit and secure with the M3 screw at bottom. 1 12 2 11 3 10 4 9 5 8 6 7 operation and installation manual zappi 35 Installation Setup Switching On After completing and checking the wiring of the supply, the sensor(s), switch on the zappi via the circuit breaker. zappi will start-up and the main screen will be presented after a few seconds. If zappi has been installed alongside another zappi unit or another myenergi device, refer to Linking Devices (page 24) for guidance on pairing devices. Also refer to the instruction documentation for the other devices. Testing Before leaving site, it is wise to perform a few checks to ensure that the sensors have been correctly installed and are functional. 1. Check that the time and date are correct and displayed at the bottom left of the main screen. If they are not present or are incorrect, set the correct time and date in the Other Settings/Time & Date menu option. 2. Check that the EV will charge in FAST mode. 3. Check the Grid Power reading at the top right of the main screen is showing sensible readings and the direction of power flow is as expected. 4. With the EV plugged in, switch to ECO mode charging and check that the charge power is at minimum (about 1.4kW) OR that it is 'tracking' the surplus power (i.e. the Grid Power reading is 0.0kW) 5. If a Generation Sensor has been installed, check that the generated power is shown at the top left of the main screen. If the generation reading is missing, the most likely cause is the CT2 input is not enabled � see CT Config on page 22. Or, if the Grid Sensor is instead wired to a harvi ensure the device settings are correct � see Device Settings on page 24. 36 zappi operation and installation manual Troubleshooting Troubleshooting Symptom Cause Solution Display is blank - There is no power to the unit - Check for correct supply voltage at the supply screw terminals (220 - 260V AC) In ECO+ mode, the charge does not start, the display is always showing Waiting for Surplus and the export power is 0W - Grid Sensor incorrectly installed - Faulty Grid Sensor - No signal from harvi (if used) - Check the grid sensor is connected to CT1 terminals of the zappi or harvi - Check the Grid CT sensor is installed on the correct cable (see Grid CT page 30) - Check resistance of the sensor - it should be around 200 when not connected (remove the sensor from the cable before testing resistance) - If using harvi, check that the CT input has been set to Grid in the harvi settings (under Devices in the zappi menu) In ECO+ mode, the charge does not start, the display is always showing Waiting for Surplus, yet the export power is showing correctly - Export Margin set too high - Check Export Margin setting (default is 0W) Generation power is always 0.0kW - Generation sensor not installed - Install generation sensor and connect to CT2 input - Alternatively, the Generation and House consumption figures can be hidden on the main screen by setting CT2 Input in the Advanced Settings menu to OFF Faults If any of the following fault messages are displayed, follow the action described.
