and procedures for planning and installing the PV100S 100 kW Grid-Tied
Photovoltaic Inverter.
Scope
The Manual provides safety guidelines, detailed planning and setup information,
and procedures for installing the inverter.
Audience
The Manual is intended for use by anyone who plans to construct or install a
system involving the PV100S 100 kW Grid-Tied Photovoltaic Inverter. 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.
Organization
This Manual is organized into four chapters:
Chapter 1, “Introduction” provides information about the features and functions
of the PV100S 100 kW Grid-Tied Photovoltaic Inverter.
Chapter 2, “Planning” provides information to help plan the installation of the
PV100S 100 kW Grid-Tied Photovoltaic Inverter.
Chapter 3, “Installation” describes the procedures needed to install the PV100S
100 kW Grid-Tied Photovoltaic Inverter. This section includes unpacking and
moving instructions, mounting instructions, and cabling instructions.
Chapter 4, “Verification” provides a checklist to ensure the installation of the
PV100S is correct and complete.

Conventions Used
The following conventions are used in this guide.
This Manual contains information for two models of the PV100S 100 kW Grid-
Tied Photovoltaic Inverter. One model is designed to operate with a 208 Vac
utility input, and the other model is designed to operate with a 480 Vac utility
input.
• The model PV100S-208 100kW Grid-Tied Photovoltaic Inverter
(208 Vac input) will be referred to as the PV100S-208 when it is being
referenced individually.
• The model PV100S-480 100kW Grid-Tied Photovoltaic Inverter
(480 Vac input) will be referred to as the PV100S-480 when it is being
referenced individually.
• When the both models are being referenced together, they will be referred to
as the PV100S.
WARNING
Warnings identify conditions or practices that could result in personal injury or loss of life.
CAUTION
Cautions identify conditions or practices that could result in damage to the unit or other
equipment.
Important: These notes describe things which are important for you to know, but not as
serious as a caution or warning.

Important Safety Instructions
SAVE THESE INSTRUCTIONS - DO NOT DISCARD
This manual contains important safety instructions for the PV100S that shall be
followed during installation and maintenance procedures.
WARNING: Shock Hazard
Read and keep this Planning and Installation Manual for future reference. Before
installing PV100S (either model), read all instructions, cautionary markings, and all other
appropriate sections of this manual. Failure to adhere to these warnings could result in
severe shock or possible death. Exercise extreme caution at all times to prevent accidents.
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. These servicing instructions are for use by qualified personnel who 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. 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. 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.

Safety
viii 152315 Rev C
General Safety Precautions
1. When installing the PV100S use only components recommended or sold by
Xantrex. Doing otherwise may result in a risk of fire, electric shock, injury to
persons, and will void the warranty.
2. Do not attempt to operate the PV100S if it has been dropped, or received more
than cosmetic damage during transport or shipping. If the PV100S is
damaged, or suspected to be damaged, see the Warranty for this unit in the
PV100S 100 kW Grid-Tied Photovoltaic Inverter Operation and Maintenance
Manual.
3. To reduce the risk of electrical shock, lock-out and tag the PV100S before
attempting any maintenance, service, or cleaning.
Personal Safety
Follow these instructions to ensure your safety while working with the PV100S.
Safety Equipment
Authorized service personnel must be equipped with standard safety equipment
including the following:
• Safety glasses
• Ear protection
• Steel-toed safety boots
• Safety hard hats
• Padlocks and tags
• Appropriate meter to verify that the circuits are de-energized
(600 Vac and DC rated, minimum)
Check local safety regulations for other requirements.
Wiring Requirements
1. All wiring methods and materials shall be in accordance with the National
Electrical Code ANSI/NFPA 70. When sizing conductors and conduits
interfacing to the PV100S, both shall be in accordance with the National
Electric Code ANSI/NFPA 70, as well as all state and local code
requirements.
2. Use copper conductors only with insulation rated for 90 °C.
3. The PV100S has a three-phase output. It is marked with this symbol:
4. The AC power conductor wiring interfacing with the AC terminals in the
Transformer Enclosure are located at T6-X1, T6-X2, and T6-X3. These
terminals should be tightened to a torque value of 420 in-lbs (47.5 Nm) for
model PV100S-208 and model PV100S-480. Conductors terminated to these
