Interconnection Standards Compliance
The PV100S has been tested and listed by Underwriters Laboratories to be in
compliance with UL 1741 Static Inverters And Charge Controllers For Use In
Photovoltaic Power Systems, as well as IEEE-929-2000 Recommended Practice
For Utility Interface of Photovoltaic (PV) Systems.
UL 1741 is the standard applied by Underwriters Laboratory to the PV100S to
verify it meets the recommendations of IEEE-929-2000.
IEEE-929-2000 provides guidance regarding equipment and functions necessary
to ensure compatible operation of photovoltaic systems which are connected in
parallel with the electric utility.
Refer to both documents for details of these recommendations and test
procedures.
Chapter 1, “Introduction” provides information about the features and
functions of the PV100S 100 kW Grid-Tied Photovoltaic Inverter.
Introduction
Description of the PV100S
The PV100S 100 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 100 kW. Designed to be easy to install
and operate, the PV100S automates start-up, shutdown, and fault detection
scenarios. With user-definable power tracking that matches the inverter to the
PVarray and adjustable delay periods, users are able to customize start up and
shut down sequences. Multiple PV100S inverters are easily paralleled for larger
power installations.
The PV100S 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, galvanized steel enclosure, the PV100S
incorporates sophisticated Intellimod
(IGBTs) as the main power switching devices. An advanced, field-proven,
Maximum Peak Power Tracker (MPPT) integrated within the PV100S control
firmware ensures the optimum power throughput for harvesting energy from the
photovoltaic array.
The advanced design of the PV100S 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.
®
(IPM) Insulated Gate Bipolar Transistors
Additionally, the PV100S 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 PV100S includes a local user interface
comprised of an O
user-friendly, Graphic User Interface (GUI) provides a remote interface for
operator interrogation of PV100S system status, control, metering/data logging
and protective functions within the PV100S. The status, control, and lo gging
features are also supported by the choice of three communication mediums,
allowing the information to be accessed or commanded remotely.
The PV100S comes in two modules comprised of six enclosures to house the
electronics described above. The first module includes the Main Inverter
Enclosure, Inductor Enclosure, DC Interface Enclosure, and Communication
Enclosure. The second module includes the Transformer Enclosure and AC
Interface Enclosure. These components are identified in Figure 1-1 on page 1–3.
Figure 1-1 also shows the dimensions and locations of the various enclosures that
comprise the PV100S.

Introduction
System Specifications
The PV100S has been designed for photovoltaic power systems, which operate
within the following specifications.
CAUTION: Equipment Damage
Operation of the PV100S in a manner other than specified in this Manual may cause
damage to the PV100S and other system components and will void the terms of the
warranty.

Voltage and Frequency Ranges
Table 1-2 provides the over-voltage, under-voltage, over-frequency, and
under-frequency detection limits for the PV100S. These detection limits have
been factory tested and deemed to be in compliance with IEEE-292 and UL 1741
requirements for utility interaction.
This product is intended to be installed as part of a permanently grounded
electrical system per the National Electrical Code ANSI/NFPA 70. A copper
ground rod must be installed within three feet of the PV100S enclosures and
connected to the unit as described in “System Grounding” on page 3–12. The
single-point ground for the system is to be made at the AC ground bus bar (TB2)
in the AC Interface Enclosure.
System Neutral Requirements
The PV100S is designed to be installed as a 4-wire system. As required by the
UL 1741 listing, a neutral conductor from the utility-interconnect must be
terminated at TB6 within the AC Interface Enclosure to ensure that the AC
voltage sensing circuit can perform an individual phase voltage (line-to-neutral)
measurement. The function of the neutral connection is to provide a point of
reference for measurement purposes that is essentially at ground potential. No
power will flow through the neutral conductor.
Utility Side Isolation Transformer Requirements
The PV100S is supplied with a high-efficiency custom Wye:Wye isolation
transformer as part of the AC Interface/Transformer assembly. The utility side
windings of the isolation transformer are configured Wye and must match the
voltage at the utility inter-tie. The PV100S is a balanced, three-phase,
current-sourcing inverter and only operates with the presence of a stable utility
voltage. The transformer is also supplied with a neutral connection on the utility
interconnect. Connection of this utility-side neutral does not affect the operation
of the inverter; however, connection of the neutral on the inverter -side does af fect
the operation and must be left floating or disconnected. Single-phase, grounded
loads, which may be present between the transformer and utility, will maintain
their existing ground reference at the utility distribution transformer.
System Specifications
CAUTION: Equipment Damage
If the Isolation Transformer (T6-X0) neutral terminal is tied to ground, it will cause
irreparable damage to the PV100S. Check local regulations for their requirements
regarding the connection of the neutral.
WARNING: Lethal Voltage
Grounding the neutral of a Wye-wound transformer may create an “open delta” condition,
depending on the utility configuration. This condition may keep the PV100S from
detecting a loss of phase condition on the utility system, which may allow potentially
lethal voltage to be present on the open-phase wiring.

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 PV100Sis
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
position.
The DC Disconnect Switch 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 PV100Sis 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 PV100S 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.

Introduction
PC Connection Methods
A PC can be used to access the system status and programming features of the
PV100S. A PC can be connected either directly or remotely.
1. Remote Connect uses one of the three kits below.
•POTS Kit - uses a MultiTech® 56K Modem, RS232/Fiber Optic
•Wireless Kit - uses a GSM Wireless Modem.
•Ethernet LAN Kit - uses a data communication device to enable the unit
2. Direct Connect is used for troubleshooting. It uses a RS232/Fiber Optic
Converter (configured for a PC), a DB25-to-DB25 gender changer, and a
DB25-to-DB9 Serial Cable.
The Xantrex Solar GUI software is included to provide a graphic user interface
that relates important system information. For additional information, see
"Computer Communications with the PV100S" in the Operation chapter of the
PV100S 100 kW Grid-tied Photovoltaic Inverter Operation and Maintenance
Manual.
The GUI can dial up the inverter and receive fault report calls from it through a
standard Hayes-compatible, landline modem. When the GUI initiates a call
through the modem at the GUI computer, the inverter’s modem answers the call
and initiates a 9600 baud serial connection, effectively as if the GUI was
connected directly. Or, if the inverter experiences a fault, it will initiate a call to
the GUI and report the fault details.

Planning
Chapter 2, “Planning” provides information to help you plan the
installation of the PV100S 100 kW Grid-Tied Photovoltaic Inverter.
Planning
Overview of PV100S Installation
WARNING: Shock Hazard
Installations of this equipment should only be performed by qualified technicians.
Installers must meet all local and state code requirements for licensing and
training for the installation of Electrical Power Systems with AC and DC voltage
to 600 volts.
PlanningPlanning for a system requires complete understanding of all the components that
are involved to successfully install the PV100S to meet the required national,
state, and local codes.
DefinitionA power system (such as the PV100S) is a collection of devices designed to
supply AC power to the utility grid from a solar energy (PV) source.
ComponentsAll types of grid-tied inverter installations, residential or industrial, share common
components. This chapter describes each component and suggests the minimum
requirements for a safe installation.
LocationThe PV100S 100 kW Grid-Tied Photovoltaic Inverter is designed to be installed
in either an indoor or outdoor location. The PV100S must be anchored to a level
concrete floor or pad.
Ideally the AC Interface Enclosure/Transformer assembly is placed on the left
side of the Main Inverter Enclosure. The AC Interface Enclosure/Transformer
assembly may be co-located adjacent to the left side of the Main Inverter
Enclosure up to, but not exceeding, 15 feet away. See “Layout Options” on
page 2–6.
ClearanceAdequate ventilation and service access must be taken into consideration when
installing the PV100S. See “Ventilation and Serviceability Requirements” on
page 2–3 for specific clearance requirements and ambient temperature
requirements.
Conduits and
Conductors
Given the flexibility to co-locate the AC Interface Enclosure/Transformer
assembly to fit a desired system layout, the conduits and conductors are to be
supplied by the installer.
See “Conduit Penetration” on page 2–8 for recommendations on enclosure
penetration locations and conduit routing.
See “Conductor and Conduit Sizing” on page 2–11 for information on sizing the
conductors and conduits.
All interconnect wiring and power conductors interfacing to the PV100S must be
in accordance with the National Electrical Code ANSI/NFPA 70 and any
applicable local codes.
2–2152973 Rev A
Large gauge wire must conform to the minimum bend radius specified in the
NEC, Article 373-6B, Ninth Edition.
T ake care to keep the wire bundles away from any sharp edges which may damage
wire insulation over time.
All conductors should be made of copper and rated for 90 °C (minimum).
If the installation of the PV100S is to be outdoors, all interconnect conduit and
fittings must be NEMA 4 rated as required by the NEC.
PV Planning
To determine the number of photovoltaic panels that are required for the PV
power plant, please use the PV planning tool from the Xantrex website:
The following environmental conditions must be established and maintained to
ensure the safe and efficient operation and servicing of the PV100S. Adequate
space must be provided around the unit for ventilation and access during
servicing. If locating the unit indoors, ambient air temperature cannot exceed the
maximum temperature for which the unit is rated.
PV Planning
VentilationMaintain a minimum clearance of 12 inches on both sides and 6 inches behind the
Main Inverter Enclosure and the AC Interface Enclosure for proper cooling fan
operation.
Maintenance and
Serviceability
Indoor Temperature
Control
Maintain a minimum clearance of 36 inches in front of the main inverter access
door, the Transformer Enclosure access panel, and the AC Interface access door
for maintenance and serviceability.
See Figure 2-1 on page 2–6 and Figure 2-2 on page 2–7 for illustrations of these
clearance requirements.
If the PV100S is to be installed indoors and external air is used for ventilation, the
required cubic feet per minute (CFM) rate must be no less than 1000 CFM. This
assumes the temperature inside the building is allowed to rise only 10 °C above
the outside temperature. Therefore, the maximum allowable outside ambient
temperature is 50 °C (50 °C minus 10 °C equals 40 °C Maximum Am bient
Temperature). (See “Environmental Specifications” on page 1–6).
If air conditioning is planned for an indoor installation, the heat load of the
PV100S is 1800 BTU/Hour at full load.
152973 Rev A2–3
Planning
Ground Requirements
This product is intended to be installed as part of a permanently grounded
electrical system per National Electrical Code ANSI/NFPA 70. A copper ground
rod must be installed within three feet of the PV100S enclosure. This is the single
point earth ground for the inverter system. The single point ground for the system
is to be made at the AC ground bus bar (TB2) in the AC Interface Enclosure.
System Neutral Requirements
The PV100S is designed to be installed as a 4-wire system. As required by the
UL 1741 listing, a neutral conductor from the utility-interconnect must be
terminated at TB6 within the AC Interface Enclosure to ensure that the AC
voltage sensing circuit can perform an individual phase voltage (line-to-neutral)
measurement. The function of the neutral connection is to provide a point of
reference for measurement purposes that is essentially at ground potential. No
power will flow through the neutral conductor.
Communication Requirements
The PV100S can accommodate any one of the following options for PC
Communication:
•POTS Connect Kit uses a MultiTech® 56K Modem, RS232/Fiber Optic
Converter (configured for Ethernet) and SA2 Surge Arrestor. A direct analog
phone line to the local phone service is required to use this feature. The phone
line used for PV100S communication cannot be routed through a Private
Branch Exchange (PBX) unless an analog PBX card is used.
•Wireless Connect uses a GSM Wireless Modem.
•Ethernet LAN Connect uses a data communication device to enable the unit
to connect to a LAN.
•Direct Connect Kit uses a RS232/Fiber Optic Converter (configured for a
PC), a DB25-to-DB25 gender changer, and a DB25-to-DB9 Serial Cable.
Determine which communications options are required for the installation and
procure the appropriate service or phone access. The PC to be used with this unit
must have the appropriate hardware as well, such as a 56K modem for dial up
connection or a Network Interface Card (NIC) for a LAN connection.
Utility Side Isolation Transformer Requirements
The PV100S is supplied with a high-efficiency custom Wye:Wye isolation
transformer as part of the AC Interface/Transformer assembly. The utility side
windings of the isolation transformer are configured Wye and must match the
voltage at the utility inter-tie. The PV100S is a balanced, three-phase, currentsourcing inverter and only operates with the presence of a stable utility voltage.
The transformer is also supplied with a neutral connection on the utility
2–4152973 Rev A
interconnect. Connection of this utility-side neutral does not affect the operation
of the inverter; however, connection of the neutral on the inverter -side does af fect
the operation and must be left floating or disconnected. Single-phase, grounded
loads, which may be present between the transformer and utility, will maintain
their existing ground reference at the utility distribution transformer.
CAUTION: Equipment Damage
If the Isolation Transformer (T6-X0) neutral terminal is tied to ground, it will cause
irreparable damage to the PV100S. Check local regulations for their requirements
regarding the connection of these neutrals.
WARNING: Lethal Voltage
Grounding the neutral of a Wye-wound transformer may create an “open delta” condition,
depending on the utility configuration. This condition may keep the PV100S from
detecting a loss of phase condition on the utility system, which may allow potentially
lethal voltage to be present on the open-phase wiring.

Conductor and Conduit Sizing
All wiring methods and materials shall be in accordance with the National
Electrical Code ANSI/NFP A 70. When sizing conductors and conduits interfacing
to the PV100S, both shall be in accordance with the National Electrical Code
ANSI/NFPA 70, as well as all state and local code requirements.
Large gauge wire must conform to the minimum bend radius dependent upon the
wire gauge(refer to the National Electrical Code, Article 373-6B (Ninth Edition).
CAUTION: Equipment Damage
Be careful to keep the wire bundles away from any sharp edges which may damage wire
insulation over time.
The following section provides information on sizing the conductors and conduits
for the system.
To calculate the proper conduit size:
1. Determine the required cable ampacity.
2. Determine the conduit length between the inverter and the transformer.
Conductor and Conduit Sizing
3. Determine the proper size for the cable according to the allowable ampacities
indicated by NEC Table 310.16 or 310.17 (Ninth Edition).
4. Determine the proper size for the conduit.
The following section is an example of the steps outlined above. Assumptions
were made in this example which may not match your application, and the
resulting design may not comply with all code requirements. Consult a licensed
electrician on recommendations for specific installations.
Step 1. Determine the required cable ampacity.
AC Phase Cables from Inverter to Transformer:
100 kW / 208 Vac / 1.732 = 277.5 A
277.5 x 125% = 347 A (required ampacity)
Step 2. Determine the conduit length between inverter and transformer.
•If the conduit length between the inverter and the transformer is less than
24 inches, then the cable can be sized using the NEC Table 310.17
(Free Air) (Ninth Edition).
•If the conduit length is greater than 24 inches, then the cable must be sized
using NEC Table 310.16 (in Raceway) (Ninth Edition).
(full load current)
rms
152973 Rev A2–11
Planning
Step 3. Size the cable.
This example assumes that the conduit length is less than 24 inches. NEC
Table 310.17 (Ninth Edition) indicates the Temperature Correction Factor for
90 °C THHN cable in a 50 °C ambient is 0.82. With a required ampacity from
Step 1 of 347 amps, it can be calculated that the required cable ampacity at 50 °C
in this application is 423 amps. (347 divided by 0.82)
In this example, a single cable is desired, so from NEC Table 310.17 (Ninth
Edition) it is apparent that the 90 °C THHN cable must be 250 KCMIL or larger.
Step 4. Size the conduit.
In this step, the cross sectional area of all the individual cables is first calculated.
Once calculated, the total cross sectional area of the cables is determined by
summing their values. In this example, 262 KCMIL DLO, 2000 V cable is
selected for the AC Phase connections:
DLO 262 Cable:
262 KCMIL DLO, 2000V, 90 °C per Phase
262 KCMIL has an O.D. of 0.973
0.973 x 0.973 x 3 x 0.7854 = 2.23 in²
Ground Cable:
1 Each #2 AWG (per NEC Table 250.122 (Ninth Edition),
using 400 A Breaker)
#2 AWG has an O.D. of 0.384 for THHN and 0.565 for DLO
0.565 x 0.565 x 0.7854 = 0.250 in²
Sense/Control Wires:
8 Each #16 AWG, UL1015, THHN, Hook-up Wire
#16 AWG has an O.D. of 0.096
0.096 x 0.096 x 8 x 0.7854 = 0.058 in²
Total:
2.23 + 0.250 + 0.058 = 2.538 in²
Using the "Over 2 Wires" column per NEC Chapter 9, Table 4, (Ninth Edition)
indicates that the following minimum permitted conduit trade size is acceptable
for the 12 wires in this exercise:
The PV100S is designed to be installed in either an indoor or outdoor location.
The PV100S must be placed on and anchored to a level concrete floor or pad. The
concrete floor or pad must be structurally designed to meet any local, state, or
national requirements for weight, seismic, and wind sheer if applicable. The
concrete floor or pad should either be pre-drilled to accept masonry anchors or
have pre-installed anchoring bolts.

Conduit Installation
Given the flexible nature of the system, conduit installation will be dependent
upon the final configuration of the system. Procurement and installation of the
conduit, therefore, is the responsibility of the installer. Since the layout will be
dependent upon the location available for the installation and the size of the
conductors used, specific conduit size and type must be pre-determined by the
installer before the actual installation. See “Conductor and Conduit Sizing” on
page 2–11 for instructions on how to determine the size of the conductors and
conduits to be used. Once the size of the conductors and conduits has been
determined, follow the instructions below for installing the conduits. Be sure to
consult the NEC Handbook and any local codes to ensure code compliance.
Conduit Installation
Important:
PV100S be NEMA 4 rated.
To install the conduits:
1. Determine the conduit penetration locations in the Main Inverter Enclosure
and the AC Interface Enclosure/Transformer assembly. See Figure 2-3 on
page 2–8 through Figure 2-5 on page 2–9.
2. Install appropriately-sized conduit based upon system layout and required
codes between the Main Inverter Enclosure and the AC Interface
Enclosure/Transformer assembly. For ease of conduit installation, the access
panels on both the Main Inverter Enclosure and the AC Interface
Enclosure/Transformer assembly can be removed.
3. Determine all remaining conduit penetration locations in the AC Interface
Enclosure, DC Interface Enclosure, and Communication Enclosure. See
Figure 2-3 on page 2–8 through Figure 2-8 on page 2–10.
4. Install all remaining appropriately sized conduit interfacing for the AC
Interface Enclosure, DC Interface Enclosure, and Communication Enclosure
based upon system layout and required codes.
Outdoor installations require that all conduit fittings interfacing with the

electric shock, do not perform any servicing other than that specified in the installation
instructions unless you are qualified to do so. Do not open the cabinet doors if extreme
moisture is present (rain or heavy dew).
WARNING: Lethal Voltage
In order to remove all sources of voltage from the PV100S, the incoming power must be
de-energized at the source. This may be done at the main utility circuit breaker and by
opening the AC Disconnect and the DC Disconnect Switches on the PV100S. 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.
CAUTION: Equipment Damage

152973 Rev A3–13
Installation
System Neutral Requirements
The PV100S is designed to be installed as a 4-wire system. As required by the
UL 1741 listing, a neutral conductor from the utility-interconnect must be
terminated at TB6 within the AC Interface Enclosure to ensure that the AC
voltage sensing circuit can perform an individual phase voltage (line-to-neutral)
measurement. The function of the neutral connection is to provide a point of
reference for measurement purposes that is essentially at ground potential. No
power will flow through the neutral conductor.
Utility Side Isolation Transformer Requirements
The PV100S is supplied with a high-efficiency custom Wye:Wye isolation
transformer as part of the AC Interface/Transformer assembly. The utility side
windings of the isolation transformer are configured Wye and must match the
voltage at the utility inter-tie. The PV100S is a balanced, three-phase,
current-sourcing inverter and only operates with the presence of a stable utility
voltage. The transformer is also supplied with a neutral connection on the utility
interconnect. Connection of this utility-side neutral does not affect the operation
of the inverter; however, connection of the neutral on the inverter-side does affect
the operation and must be left floating or disconnected. Single-phase, grounded
loads, which may be present between the transformer and utility, will maintain
their existing ground reference at the utility distribution transformer.
CAUTION: Equipment Damage
If the Isolation Transformer (T6-X0) neutral terminal is tied to ground, it will cause
irreparable damage to the PV100S. Check local regulations for their requirements
regarding the connection of these neutrals.
WARNING: Lethal Voltage
Grounding the neutral of a Wye-wound transformer may create an “open delta” condition,
depending on the utility configuration. This condition may keep the PV100S from
detecting a loss of phase condition on the utility system, which may allow potentially
lethal voltage to be present on the open phase wiring.

The RS232/FO Converter kit (Xantrex P/N 1-152624-01) is required for this
connection to change the communication protocol from Ethernet to serial in the
Communication Enclosure. A DB25-to-DB25 gender-changer adapter and
DB9/DB25 serial cable are provided with the RS232/FO Converter kit to
complete the connection.
For a system level view, see Figure 1-10 on page 1–14 which shows the PV 100S
connected directly to a PC.
If connecting the PC directly to the inverter:
1. Open the Communication Enclosure. See Figure 3-21 and Figure 3-22.
2. Disconnect the TX (transmit-orange) and RX (Receive-blue) wires from the
installed RS232/FO Converter in the Communication Enclosure.
3. Disconnect the power plug from the installed converter and plug it into the
new RS232/FO Converter.
4. Remove the installed converter and replace with the new RS232/FO
Converter.
5. Reconnect the TX (transmit-orange) and RX (Receive-blue) wires to the new
Converter in the Communication Enclosure.
6. Plug the DB25-to-DB25 Gender-changer Adapter into the Serial
Communications Port on the RS232/FO Converter. (Step not shown.)
7. Plug the DB25 connector on the serial cable into the gender-adapter and the
DB9 connector of the serial cable into the serial port on the computer. (Step
not shown.)

Verification
Chapter 4, “Verification” provides a checklist to ensure the
installation of the PV100S is correct and complete.
Verification
Verification Procedure Summary
WARNING: Electrocution Hazard
This chapter describes specific steps to ensure the installation of the PV100S 100 kW
Grid-Tied Photovoltaic Inverter is correct and complete. Failure to adhere to these
warnings could result in severe shock or possible death. Exercise extreme caution at all
times to prevent accidents. These installation instructions are for use by those familiar
and skilled with high voltage procedures.
WARNING: Shock Hazard
The PV100S enclosures contain exposed high-voltage conductors. The enclosure doors
should remain closed with the latches tightened, except during installation, maintenance
or testing. To reduce the risk of electric shock, do not perform any servicing other than
that specified in the installation instructions unless you are qualified to do so.
WARNING: Lethal Voltage
In order to remove all sources of voltage from the PV100S, 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 PV100S. 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.
The following procedures are intended to verify correct installation and proper
wiring of the PV100S. Prior to performing the following verification steps on the
PV100S, review all safety requirements and procedures outlined in this Manual
and on any cautionary markings on the components within the system.
Inspect the following items prior to completion of the installation:
1. Visually inspect all the mechanical connections. This would include both
electrical conduit fittings, as well as enclosure anchoring and seismic bracing
if required.
2. Visually inspect the electrical connections and verify proper tightness of all
terminations.
3. Visually inspect the Isolation Transformer Wye:Wye connections and ensure
the T6-X0 neutral connection is left disconnected or floating.
4. Perform corrective actions if required.

Visual Inspection of Mechanical Connections
Visual Inspection of Mechanical Connections
To perform a visual inspection of the PV100S mechanical connections:
1. Ensure that the AC and DC Disconnect Switches, as well as any utility
interconnect circuit breakers or main disconnect switches, are opened.
2. Ensure all anchor bolts and any required seismic bracing is properly
tightened and in place.
3. Remove the wiring access panels and front covers from the AC
Interface/Transformer assembly and Main Inverter Inductor Enclosure.
4. Remove the latches and open the doors of the Main Inverter Enclosure,
the AC and DC Interface Enclosures, and Communication Enclosure
and inspect.
5. Verify all wire conduit fittings and connections are properly tightened.p
Visual Inspection of Electrical Connections
To perform a visual inspection of the PV100S electrical connections:
1. Ensure that the AC and DC Disconnect Switches, as well as any utility
interconnect circuit breakers or main disconnect switches, are opened.
2. Ensure all conductors and wiring connections interfacing with the
PV100S are tightened to the correct torque value.
For specific torque values, see Table 3-1, “AC Terminal Wire Gauge,
Bolt Size, and Torque Values” on page 3–12 and Table 3-2, “DC
Terminal Wire Gauge, Bolt Size, and Torque Values” on page 3–12.

3. Verify AC power conductors terminated at TB4-A, TB4-B, TB4-C
within the Main Inverter Enclosure are terminated correctly and
properly sequenced.
4. Verify the AC power conductors terminated at S1-2T1, S1-4T2, S1-6T3
within the AC Interface Enclosure are terminated correctly and properly
sequenced.
5. Verify DC power conductors terminated at TB3-1, TB3-2, TB3-3 within
the DC Interface Enclosure are terminated correctly and properly
polarized.

Visual Inspection, Isolation Transformer Wye:Wye
To perform a visual inspection of the Isolation Transformer Wye:Wye:
1. Ensure that the AC and DC Disconnect Switches, as well as any utility
Interconnect circuit breakers or main disconnect switches, are open.
2. Verify all conductor and wiring connections interfacing with the
PV100S are tightened to the correct torque value.
For specific torque values, see Table 3-1, “AC Terminal Wire Gauge,
Bolt Size, and Torque Values” on page 3–12 and Table 3-2, “DC
Terminal Wire Gauge, Bolt Size, and Torque Values” on page 3–12.
3. Verify the AC power conductors terminated at T6-X1, T6-X2, T6-X3
within the Transformer Enclosure are terminated correctly and properly
sequenced.
4. Ensure the neutral on the inverter side (T6-X0) is left floating. If the
inverter side neutral is tied to ground, the inverter will not function
properly. Also, ensure that the neutral is not bonded to the isolation
transformer frame.
