PV Planning

PV Planning

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	Maintain a minimum clearance of 36 inches in front of the main inverter access
Serviceability	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	If the PV100S is to be installed indoors and external air is used for ventilation, the
Control	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.
