1Introduction

Chapter 1, “Introduction” contains information about the features and

functions of the PV225S 225 kW Grid-Tied Photovoltaic Inverter.

Introduction

1–2 152607

Operation Features

The PV225S 225 kW Grid-Tied Photovoltaic Inverter is a UL 1741 listed, utility

interactive, three-phase power conversion system for grid-connected photovoltaic

arrays with a power rating of 225 kW. Designed to be easy to install and operate,

the PV225S automates start-up, shutdown, and fault detection scenarios. With

user-definable power tracking that matches the inverter to the array and adjustable

delay periods, users are able to customize startup and shutdown sequences.

Multiple PV225S inverters are easily paralleled for larger power installations.

The PV225S power conversion system consists of a pulse-width modulated

(PWM) inverter, switch gear for isolation and protection of the connected AC and

DC power sources, and a high efficiency custom Wye:Wye isolation transformer.

Housed in a rugged NEMA-3R rated, powder-coated steel enclosure, the PV225S

incorporates sophisticated Intellimod® (IPM) Insulated Gate Bipolar Transistors

(IGBT’s) as the main power switching devices. An advanced, field-proven,

Maximum Peak Power Tracker (MPPT) integrated within the PV225S control

firmware ensures the optimum power throughput for harvesting energy from the

photovoltaic array.

The advanced design of the PV225S includes an EMI output filter and the main

AC contactor located electrically on the utility side of the isolation transformer.

The location of the main AC contactor, and the ability to de-energize the isolation

transformer during times of non-operation, greatly reduces the night-time tare

losses consumed by an idle isolation transformer. An integrated soft-start circuit

precludes nuisance utility-tie circuit breaker trips as the result of isolation

transformer inrush current.

Additionally, the PV225S integrated controller contains self-protection features

including over and under voltage and frequency safeguards. An integral

anti-island protection scheme prevents the inverter from feeding power to the grid

in the event of a utility outage.

The PV225S includes a local user interface comprised of an ON/OFF switch,

keypad, and 4-line, 80 character LCD display. A user-friendly Graphic User

Interface (GUI) provides a remote interface for operator interrogation of PV225S

system status, control, metering/data logging and protective functions within the

PV225S. The status, control, and logging features are also supported by the choice

of three communication mediums, allowing the information to be accessed or

commanded remotely.

Fixed Unity Power Factor Operation

The Xantrex PV Series of grid-tied inverters maintains unity power factor during

operation. The control software constantly senses utility voltage, and constructs

the output current waveform to match the utility voltage. The PV line of inverters

is not capable of operation without the presence of normal utility voltage, nor is it

capable of varying the output power factor off unity.

Operation Features

152607 1–3

Peak Power Tracking

An advanced, field-proven, Maximum Peak Power Tracker (MPPT) algorithm

integrated within the PV225S control software ensures the optimum power

throughput for harvesting energy from the photovoltaic array. The peak power

voltage point of a PV array can vary, primarily depending upon solar irradiance

and surface temperature of the PV panels. This peak power voltage point is

somewhat volatile, and can easily move along the I-V curve of the PV array every

few seconds. The MPPT algorithm allows the PV225S to constantly seek the

optimum voltage and current operating points of the PV array, and maintain the

maximum peak PV output power.

Accessible via the UFCU, there are five user settable parameters that control the

behavior of the maximum peak power tracker within the PV225S. As show in

Figure 1-1 on page 1–4, user settable parameters include:

• PPT V Ref (ID# 37),

• I PPT Max (ID#42),

• PPT Enable (ID# 44),

• PPT Rate (ID# 45), and

• PPT V Step (ID# 46).

Upon entering the Power Tracking mode, it takes approximately 20 seconds for

the PV225S to ramp the PV voltage to the “PPT V Ref” setpoint regardless of the

actual PV voltage.

With the “PPT Enable” set to “0” (power tracker disabled), the PV225S will

regulate the DC Bus at the “PPT V Ref” setpoint. Regulating the DC bus means

drawing more or less current out of the PV array to maintain this desired voltage.

With the “PPT Enable” set to “1” (power tracker enabled), followed by the

expiration of the “PPT Rate” (MPPT decision frequency), the MPPT will reduce

the reference voltage by an amount equal to the “PPT V Step” value.

At this point the MPPT will compare the amount of AC output power produced to

the previous amount of AC power produced by the PV225S. If the output power

has increased, the next change made (after “PPT Rate” has again expired) to the

reference voltage, will be in the same direction.

Conversely, if the power comparison proves undesirable, the power tracker will

reverse the direction of the change to the “PPT_V Step”. The MPPT algorithm

within the PV225S will then continue this ongoing process of “stepping and

comparing” in order to seek the maximum power throughput from the PV array.

The changes made by the MPPT to the reference voltage are restricted to ± 20% of

“PPT V Ref” and by the maximum and minimum PV input voltage (600 and

300 volts respectively). Also, the MPPT will not attempt to produce power greater

than that allowed by the “I PPT Max” setpoint. If available PV power is above the

maximum allowable power level of the PV225S, the MPPT will increase voltage

as needed to maintain output power below rated maximum.

Introduction

1–4 152607

Optimization of the PV225S MPPT will result in an increase in energy production.

The user is encouraged to study the PV array’s I-V curves and to adjust the MPPT

user settable parameters accordingly.

Dynamic DC Minimum Operating Voltage

The PV225S employs a unique approach to the minimum DC input voltage for

operation. The CCU2 constantly monitors and calculates an average of the AC

utility input voltage, thereby adjusting the required minimum DC input voltage

threshold to optimize the sinusoidal AC output current waveform. Given a

nominal input voltage of 208 Vac, the minimum DC input voltage threshold is

300 Vdc. On a transient basis, the PV225S does have the ability to adjust the

minimum DC input voltage threshold to less than 300 Vdc.

Utility Voltage/Frequency Fault Automatic Reset

In the event of a utility voltage or frequency excursion outside of preset limits, the

PV225S will stop operation and display a fault at the operator interface. Once the

utility voltage has stabilized within acceptable limits for a period of at least

5 minutes, the PV225S will automatically clear the fault and resume normal

operation. Voltage and frequency fault setpoints are detailed later in this section.

Safety Features

Safety Features

Anti-Island Protection

A condition referred to as "Islanding" occurs when a distributed generation source

(such as the PV225S Grid-tied Photovoltaic Inverter) continues to energize a

portion of the utility grid after the utility experiences an interruption in service.

This type of condition may compromise personnel safety, restoration of service,

and equipment reliability.

The PV225S employs a method for detecting the islanding condition using a

Phase-Shift-Loop (PSL). This method is implemented in the CCU2 to prevent

islanding of the PV225S. The CCU2 continuously makes minor adjustments to

the power factor phase angle above and below unity. In the event of a utility

interruption or outage, these adjustments destabilize the feedback between the

inverter and the remaining load, resulting in an over/under frequency or voltage

condition.

Upon detection of such a condition, the PV225S then performs an immediate

orderly shutdown and opens both the main AC and DC contactors. The fault

condition will remain latched until the utility voltage and frequency have returned

to normal for at least 5 minutes.

This method has been extensively tested and proven to exceed the requirements of

IEEE-929 (Recommended Practices for Utility Interface of Photovoltaic [PV]

Systems) and UL-1741 (Static Inverters and Converters for use in Independent

Power Systems).

PV Ground Fault Detection

The PV225S is equipped with a ground fault detection circuit by means of a

Hall-effect current transducer (CT8). This circuit is active when the PV array is

properly grounded. In the event of a ground fault exceeding 10 amps DC, the

PV225S will execute an immediate orderly shutdown, open both the main AC and

DC contactors, and report a ground fault on the LCD of the UFCU. The PV225S

will remain faulted until the ground fault is remedied and the advisory is cleared at

the operator interface.

For additional information, see Chapter 4, “Troubleshooting”.

DC Over-voltage Detection

In the event of DC voltage greater than 600 Vdc, the PV225S will execute an

orderly shutdown and will report a fault to the operator interface. If DC voltage

remains greater than 600 Vdc, the PV225S may be irreparably damaged.

See Chapter 4, “Troubleshooting” for further information on this fault condition.

Main Inverter Enclosure

The PV225S Main Inverter Enclosure is NEMA-3R rated and contains the power

distribution panel, the converter control unit (CCU2), and the power electronics

matrices. Also found within the Main Inverter Enclosure are some of the system

protection devices (such as the sense and control power fuses).

Power Distribution Panel

This panel contains many of the Electromechanical, protective, and control power

components necessary to support the operation of the PV225S.

Converter Control Unit (CCU2)

The CCU2 is a Digital Signal Processor (DSP) based control board that performs

numerous control and diagnostic functions associated with PV225S operation. Its

most significant tasks are control of PV225S electromechanical components and

power electronics converters, signal conditioning for high voltage signal inputs

and communication with the Universal Front Panel Control Unit, and system

sensors. The CCU2 also contains the necessary DC power supplies to support its

operation.

Power Electronics Matrices

The power electronics converters are located at the top of the PV225S main

inverter enclosure. Both the left and right matrices are comprised of six switching

transistors (IGBTs), transistor gate drive electronics, a laminated power bus, DC

capacitor bank, and an aluminum extrusion heatsink with a cooling fan. The fans

are located above each matrix heatsink.

The PV array is tied logically to the matrices DC bus within the DC interface

enclosure. The embedded CCU2 control unit manages the transfer of power

between the DC bus and the utility grid by sending digitized gating signals to the

IGBTs for producing a high-fidelity, sinusoidal output.

Inductor Enclosure

The Inductor Enclosure is NEMA-3R rated. It contains the necessary filter

components to ensure the PV225S line current meets IEEE-519 (1992, Standard

Practices and Requirements for Harmonic Control in Electrical Power Systems)

and UL 1741 (2001, Static Inverters and Converters for use in Independent Power

Systems) harmonic distortion requirements. Mounted on both the right and left

side of the lower enclosure are inductor fans to allow cooling of the line filter

components within. This enclosure also serves as the mounting base for the

PV225S Main Enclosure.

Introduction

1–8 152607

DC Interface Enclosure

The DC Interface Enclosure is NEMA-3R rated. The DC interface serves as the

connection interface between the PV array and the PV225S. This enclosure is

where the DC Disconnect Switch and DC contactor reside.

Transformer Enclosure

The Transformer Enclosure is NEMA-3R rated. The main isolation transformer

inside electrically isolates the PV225S from the utility power. Voltage-sensing

circuit wiring and soft-start circuit pass through the Transformer Enclosure from

the AC Interface Enclosure to the Main Inverter Enclosure.

AC Interface Enclosure

The AC Interface Enclosure is NEMA-3R rated. The AC interface serves as the

connection between the utility and the isolation transformer. This enclosure is

where the AC line fuses and AC Disconnect Switch reside. Also included in the

AC Interface Enclosure are the main AC contactor and transformer soft-start

circuit.

CAUTION: Equipment Damage

The fuses within the PV225S are intended for protecting the PV225S control circuitry

only. They are not intended to provide protection for the PV array or external cabling.

Operator Interface Controls

Operator interface controls are located on the front door of the main inverter

enclosure. These controls include an ON/OFF Switch, 4-line LCD display and

keypad called the Universal Frontpanel Control Unit (UFCU). Additionally there

is an AC and DC Disconnect on the AC Interface Enclosure and the DC Interface

Enclosure Doors.

Main Enclosure Door Interlock Switch

The front door of the PV225S main enclosure is equipped with an interlock switch

to preclude operation while the front door is open. Opening the door of the main

inverter enclosure will initiate an immediate controlled shutdown of the PV225S

and opens both the main AC and DC contactors. The main AC and DC contactors

cannot be closed unless the door’s interlock is in the engaged position. The

PV225S is prevented from being restarted until the door is again closed and the

switch is in the engaged position.

It is required that the PV225S main enclosure door must be locked during normal

operation. The door interlock switch does NOT remove all hazardous voltages

from inside the inverter. Before attempting to service the PV225S, follow the

de-energize Lockout and Tag procedure on page 5–3.

On/Off Switch

The PV225S incorporates a maintained position ON/OFF Switch (S3) located on

the front door of the main enclosure. Under normal conditions, the ON/OFF switch

is in the ON position. Turning the switch to the OFF position will initiate an

immediate controlled shutdown of the PV225S and open both the main AC and

DC contactors within the unit. The main AC and DC contactors cannot be closed

unless the switch is in the ON position. The PV225S is prevented from being

restarted until the ON/OFF switch is turned back to the ON position.

WARNING: Shock Hazard

Disengaging the main enclosure door interlock switch does NOT remove all hazardous

voltages from inside the inverter. Before attempting to service the PV225S, follow the

de-energize Lockout and Tag procedure on page 5–3.

Introduction

1–12 152607

AC and DC Disconnect Switches

Both AC and DC interface enclosures are equipped with lockout hasps for

personnel safety. The enclosure doors should not be opened while the PV225S is

operating.

The switch handles and shafts provide a door interlock for both the AC and DC

interface enclosures. The doors cannot be opened when the switch is in the ON

position.

The DC Disconnect Switch (S2) is equipped with an auxiliary contact block

which enables the switch to be used as a load break DC disconnect. In the event

the DC Disconnect Switch is opened while the PV225S is processing power from

the PV array, the early-break contact block will signal the CCU2 (Converter

Control Unit 2) to stop processing power prior to opening the DC Disconnect

Switch.

Additionally, opening the DC Disconnect Switch will cause the PV225S to

execute an immediate orderly shutdown, open both the main AC and DC

contactors, and report a PV disconnect fault on the LCD of the UFCU.

Communication Features

The PV225S provides two types of information to the user:

• system status and/or fault information, and

• data logging information.

System status and fault information can be accessed using the Universal Front

Panel Control Unit (UFCU) or a personal computer (PC) using the Xantrex Solar

Graphic User Interface (GUI) software. Data logging requires the use of a PC

using the GUI software.

stored in the inverter’s non-volatile memory, and are also read by the GUI and

stored at its computer in a text file.

• Configurable Parameters - The configuration parameters controlling the

inverter’s operation can be viewed and changed from a remote GUI.

See Table 2-3 on page 2–14 for a list of the Data Logging parameters available.

2Operation

Chapter 2, “Operation” contains information on the basic operation of

the PV225S 225 kW Grid-Tied Photovoltaic Inverter.

Operation

2–2 152607

Description of System Operation

Overview

The PV225S is a fully automated grid-interactive photovoltaic inverter. System

startup, system shutdown, PV power tracking, and fault detection scenarios are all

governed and monitored by the CCU2 controller within the PV225S. Manual

interaction or control of the inverter is necessary only in the event of a system

fault. Additionally, the following conditions govern operation of the PV225S.

• Stable utility AC voltage and frequency as specified in Table A-3 must be

present for all states of operation.

• PV voltage as specified in Table A-3 must be present.

• With the exception of the Matrix Test state, the ON/OFF switch, located on the

front door of the PV225S main inverter enclosure, must be switched to the ON

position for all operating states.

• The door of the main inverter enclosure must be closed with the door

interlock switch in the engaged position.

• Both the AC and DC Disconnect switches must be in the ON or closed

position.

• Fault conditions must not be present.

Faults

Fault states are automatic from any state of operation. In the event of a fault

condition, the PV225S will immediately stop processing power and execute an

immediate orderly shutdown, open both the main AC and DC contactors, and

remain in a faulted state until the fault is remedied and cleared (manually or

automatically).

Most faults are latching, and only those faults associated with grid disturbances

are auto-clearing and thus enable the PV225S to restart after a 5 minute delay

period. All fault conditions arising from within the PV225S are reported to the

UFCU (Universal Frontpanel Control Unit). The 4-line LCD on the UFCU will

display a hexadecimal value (fault code) and a brief text description of the fault.

Once the cause of the fault has been identified and corrected, and it is determined

to be safe to proceed, PV225S faults may be cleared from the UFCU keypad or

via the remote GUI.

See “Clearing Faults Manually” on page 4–3 for instructions on this procedure.

2–4 152607

Operating States

A state machine implemented within the CCU2 control software governs the

operation of the PV225S with clearly defined transitions between its operating

states. There are five steady-state operating states and numerous intermediate

transition states.

• Power Tracking

• Transition

•Shutdown

• Fault

• Manual Current

• Matrix Test

• Automatic Sleep Test

Power Tracking

This is the standard operating state of the PV225S. The PV225S maximum power

tracker will demand maximum power from the PV array, given sufficient PV

irradiance.

The user should be aware of the following conditions governing PV225S state

transitions:

• Qualified utility voltage must be present for all states of operation.

• Fault states are automatic from any state of operation. A fault will cause the

PV225S to immediately stop processing all power. The fault condition will be

reported to the operator interface LCD.

• Most PV225S faults are latching and must be cleared at the operator interface

keypad before transitioning to another operating state.

• The ON/OFF switch, located on the front door of the PV225S, must be in the

ON position for all operating states except Matrix Test, in which case it must

be in the OFF position.

Transition

The intermediate transition states provide an orderly progression from one

operating state to the next. The user has the ability to manually transition the

PV225S between operating states via the operator interface keypad or remotely

using the GUI software. Manual transitions are initiated by entering a “Goal

State”, where the goal state is the desired operating state. Given all applicable

system parameters are within acceptable limits, and the request is valid within the

state machine, the PV225S will initiate the proper sequence of operations

necessary to progress to the requested goal state. Refer to Figure 2-1 on page 2–3

for an illustration of valid state transitions.

Operating States

152607 2–5

Shutdown

The line interface controller is idle. The CCU2 monitors the status of the PV array

and utility grid, waiting in standby until the PV array is available to produce

power to the grid.

Fault

The PV225S has encountered a fault condition. When this happens, regardless of

the PV225S state of operation, the PV225S will stop processing all power and

execute an orderly system shutdown. A description of the fault and fault code will

appear on the operator interface LCD. The Fault state may be cleared from the

keypad once the cause of the fault has been corrected. See Chapter 4,

“Troubleshooting” for a complete description of all fault codes.

Manual Current

This operating state is provided to evaluate the existing PV array V-I

characteristics. The PV controller regulates a constant amount of PV current as

commanded by the user from the operator interface keypad, up to the PV current

limit of the PV225S. If the user commands more PV current than is available, the

DC bus voltage will drop below the minimum bus voltage level and the PV225S

will enter Shutdown mode.

Matrix Test

This operating state is provided to verify proper operation of the matrices and

their associated control electronics. There is no power transfer between the PV

and utility in this mode. The ON/OFF switch must be in the OFF position for the

PV225S to enter this state.

Automatic Sleep Test

Toward the end of every solar day, the PV225S automatically determines when to

stop producing power dependent upon the output power of the inverter. As the net

output power of the PV225S nears zero, a timer is started to allow the inverter to

ride through any brief irradiance reductions.

Operation

2–6 152607

Operator Interface

The purpose of the operator interface is to provide a means of communicating

critical operational information to and from the unit. This communication occurs

between the operator and the UFCU Keypad and LCD display or between the

operator and a personal computer running the Xantrex Solar GUI software.

UFCU Keypad Operation and LCD Display

The UFCU keypad is located on the front of the Main Inverter Enclosure to

manipulate and view system operation and status.

The keypad is comprised of 20 touch-sensitive, peizio electric keys that provide a

means to navigate through the menus and alter user-changeable settings.

• Four function keys are available.

• F1 - While in the READ Menu, this key is used to clear faults.

Menu Structure

The operator interface consists of three levels:

•READ Menu - operation information provided to the user from the PV225S.

The READ Menu consists of all operational values, the date and time. These

can be viewed any time the PV225S has control power.

•WRITE Menu - operational parameters provided to the PV225S from the user.

The WRITE Menu consists of a goal state sub-menu, and all system

configurable parameters. The WRITE Menu is password protected and may

only be changed by trained service technicians. In particular are parameters

relating to utility protection setpoints.

•Data Logging - the collection of specific parameters values over a period of

time. The data logging feature is only available if using the GUI. However,

the user does have the ability to view a snapshot of specific data using the

“Read by ID” feature. See Table 2-3 on page 2–14 and Table 2-4 on

page 2–14.

Information reported back to the user (READ Menu) occurs at the LCD above the

Universal Front Panel Control Unit (UFCU) and (if used) at the computer running

the GUI monitoring program. Making changes to the parameters within the WRITE

Menu is done with the UFCU keypad or the GUI software program and requires a

password.

Upon system power-up, the operator interface LCD will display the system

operating state on the first line. The inverter’s state of operation will be reported

on the second line. The PV Array’s state of operation will be reported on the third

line. The Goal target will be reported on the fourth line.

Important:

Specific grid-interface parameters within the WRITE Menu have been set in

the factory to the limits mandated by UL 1741. Any changes to these setpoints should be

agreed upon by the local utility and the equipment owner.

Important:

While in the WRITE Menu, the operator interface display will reset itself to

the standard display if there is no input for more than 2 minutes.

Computer Communications with the PV225S

The PV225S provides multiple options for communicating system status or data

logging through a personal computer using the Xantrex Solar Graphic User

Interface (GUI) software.

The Xantrex Solar Graphic User Interface (GUI) software is a Windows™-based

program that:

• displays system status,

• accesses inverter controls,

• accesses metering and data logging capabilities, and

• controls protective functions.

If multiple inverters are networked together, the software is capable of tracking up

to 50 inverters on the same network.

Determine which method will be used to communicate with the PV225S and

ensure the appropriate hardware is in place before proceeding with installing the

GUI. See the “PC Connection Methods” section of the PV225S 225 kW Grid-tied

4Troubleshooting

Chapter 4, “Troubleshooting” contains information and procedures

for troubleshooting the PV225S 225 kW Grid-Tied Photovoltaic

Inverter. It provides descriptions of common situations and errors that

may occur and provides possible solutions for resolving fault

conditions. It also provides instructions for clearing faults manually, if

required.

Troubleshooting

4–2 152607

Faults and Fault Codes

Fault states are automatic from any state of operation. In the event of a fault

condition, the PV225S will immediately stop processing power and execute an

immediate orderly shutdown, open both the main AC and DC contactors, and

remain in a faulted state until the fault is remedied and cleared (manually or

automatically).

In the event of an alarm or fault condition, the PV225S will execute an immediate,

orderly shutdown and remain in a faulted state until the alarm or fault is remedied

and cleared (manually or automatically).

• Faults associated with a grid disturbance clear automatically. The PV225S

will automatically re-start after a 5-minute delay.

• All other faults must be cleared manually.

All fault conditions arising from within the PV225S are reported to the UFCU

(Universal Frontpanel Control Unit). The 4-line LCD will display a hexadecimal

value (fault code) and a brief text description of the fault.

Most faults are latching and only those faults associated with grid disturbances are

auto-clearing and thus enable the PV225S to restart after a 5 minute delay period.

Once the cause of the fault has been identified and corrected, and it is determined

to be safe to proceed, PV225S faults may be manually cleared from the UFCU

keypad or using the remote GUI.

See “Clearing Faults Manually” on page 4–3 for instructions on this procedure.

General Troubleshooting

Respond to any PV225S alarm or fault as follows:

1. Note and document the alarm or fault code and brief text description.

2. Determine the source of the alarm or fault by referring to Table 4-1, “Fault

Codes” on page 4–4.

3. Rectify the alarm or fault condition and attempt to clear the fault from the

display. See “Clearing Faults Manually” on page 4–3 for instructions on this

procedure.

4. If the condition is sustained and cannot be corrected, again note and document

the fault code and description, and contact either your Distributor / Reseller,

or Xantrex Customer Service.

WARNING: Lethal Voltage

In order to remove all sources of voltage from the PV225S, the incoming power must be

de-energized at the source. This may be done at the Utility main circuit breaker, and by

opening the AC disconnect and the DC disconnect switches on the PV225S. Review the

system configuration to determine all of the possible sources of energy. In addition, allow

5 minutes for the DC bus capacitors, located on the ceiling of the cabinet, to discharge

after removing power.

Clearing Faults Manually

152607 4–3

Clearing Faults Manually

Faults associated with a grid disturbance clear automatically. These faults include:

• 0010 (AC Frequency Low),

• 0011 (AC Frequency High),

• 0012 AC Voltage Low), and

• 0013 (AC Voltage High) only.

Once the AC voltage and frequency return to within the acceptable range, the

PV225S will clear the fault and automatically restart after a 5-minute delay. All

other faults associated with the PV225S must be circumvented and cleared

manually using the UFCU.The following procedure describes how to manually

clear a fault message from the LCD.

To clear the fault:

1. Determine the source of the fault using Table 4-1, “Fault Codes” on page 4–4.

Correct the fault condition.

2. Ensure the fault code and “

Clear Fault?

” message is displayed in the LCD.

a) If the “

Clear Fault?

” message is not shown on the second line of the

LCD, scroll through the read parameter menu with the /\ or \/ keys until

the message appears.

3. To clear the fault, press <ENTER>. The PV225S will transition to Sleeping

mode.

are de-energized. DC bus voltage may also be present. Be sure to wait the full 5 minutes to

allow the capacitors to discharge completely.

WARNING: Shock Hazard

The terminals of the DC input may be energized if the PV arrays are energized. In

addition, allow 5 minutes for all capacitors within the main enclosure to discharge after

disconnecting the PV225S from AC and DC sources.

Maintenance Safety

152607 5–3

Lockout and Tag

Safety requirements mandate that this equipment not be serviced while energized.

Power sources for the PV225S must be locked-out and tagged prior to servicing.

Each energy source should have a padlock and tag installed on each energy source

prior to servicing.

The PV225S can be energized from both the AC source and the DC source. To

ensure that the inverter is de-energized prior to servicing, lock out and tag the

PV225S using the following procedure.

1. Open, lockout, and tag the incoming power at the utility main circuit breaker.

2. Open, lockout, and tag the AC Disconnect Switch (S1) on AC interface

assembly. See Figure 1-8 on page 1–12 for the location of the AC Disconnect

Switch.

3. Open, lockout, and tag the DC Disconnect Switch (S2) on DC interface

assembly. See Figure 1-8 on page 1–12 for the location of the DC Disconnect

Switch.

4. Using a confirmed, accurate meter, verify all power to the inverter is de-

energized. A confirmed, accurate meter must be verified on a known voltage

before use. Ensure that all incoming energy sources are de-energized by

checking the following locations.

a) Inverter Terminals: TB5, TB6, and TB7 (Phase A, B, C)

See Figure 5-1 on page 5–4.

b) Utility Terminals: Top of S1-2T1, S1-4T2, and S1-6T3

See Figure 5-2 on page 5–4.

c) PV Terminals: Bottom of S2-6, K2-6T3, and TB4 (PV+, PV-, GND)

See Figure 5-3 on page 5–5.

WARNING: Shock Hazard

Review the system schematic for the installation to verify that all available energy sources

are de-energized. DC bus voltage may also be present. Be sure to wait the full 5 minutes to

allow the capacitors to discharge completely.

Periodic Maintenance

Xantrex Technology recommends that the following preventative maintenance

procedures be carried out on the PV225S.

Monthly Intervals or As Required

Perform the following preventative maintenance tasks on a monthly basis or as

required.

Aluminum Extrusion Heatsinks

❐Inspect the aluminum extrusion heatsinks and external cooling fans for

accumulation of dirt and debris. Accumulation of dirt and debris on the

aluminum extrusion heatsinks and external cooling fans will decrease their

ability to transfer heat, which may cause the PV225S to enter a fault state

based upon an over-temperature alarm. Remove and clean if debris is present.

Fan Operation

❐Verify proper operation of the external cooling fans (B1 and B2) located

above the matrix aluminum extrusion heatsinks. These fans operate when the

K1 contactor is closed. If present, remove any debris from the fans.

Internal Circulation Fan

❐Verify the internal circulation fan (B3) is operating whenever there is utility

power applied to the PV225S.

Inductor Enclosure Cooling Fans

❐Verify that the inductor enclosure cooling fans (B4 and B5) operate whenever

the PV225S is processing power. The airflow direction should be from the

outside, forcing air into the enclosure. If present, remove any debris from the

fans.

Periodic Maintenance

152607 5–7

Six-month Intervals

Perform the following preventative maintenance tasks on a six-month basis or as

required.

Enclosure Seals

❐Inspect the enclosure access panel seal. If damaged, replace with equivalent

closed cell foam gasket. Call your Xantrex Technology distributor for factory

replacements or specifications.

Electrical Connections

❐Inspect the condition of all wiring within and interfacing to the PV225S.

❐Inspect all compression-type cable terminations and box-type connections

within the AC and DC Interface Enclosures, Main Inverter Enclosure, and

Transformer Enclosure for damage caused from high temperature.

❐Also check these terminations and connections for signs of corrosion. If any

cabling or wiring within and interfacing to the PV225S are found to be or are

suspected to be unacceptable, contact your Xantrex Technology distributor for

factory replacements or recommendations. Replacement of any damaged

wires will be necessary.

❐Verify all mechanical connections are sufficiently tightened. Verify all

conduction surfaces are clean and free of corrosion. Mechanical electrical

connections may loosen over time primarily due to thermal cycling during

normal operation. As electrical connections loosen, impedance will increase

at the connection, eventually leading to possible fire and component damage.

It is critical to check all electrical connections every six months.

See termination torque specifications for AC connections in Table A-4 on

page A–4. See termination torque specifications for DC connections in Table A-5

on page A–4.

Inductor Enclosure

❐Remove the access panels on the inductor enclosure and inspect for any

accumulated dirt and debris within the enclosure. Vacuum enclosure

whenever dust or dirt is present.
