PV Planning
152315 Rev C
2–3
Large gauge wire must conform to the minimum bend radius specified in the
NEC, Article 373-6B, Ninth Edition.
Take 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:

Ventilation and Serviceability Requirements
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.
Ventilation
Maintain 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
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.
Indoor Temperature
Control
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 Ambient
Temperature).
If air conditioning is planned for an indoor installation, the heat load of the
PV100S is 1800 BTU/Hour at full load.
