Xantrex GT500 to reduce power production. If the heat exposure is excessive, it
could also trigger an over-temperature fault detection and cease operation. It is
recommended that in high ambient conditions, the inverter be shaded as much
as possible by using either a shading structure or placing the inverter on the side
of the building that gets the least amount of direct sunlight.
If the Xantrex GT500 will be installed indoors or in a container and external air is
used for ventilation, the required air flow in cubic meters per second (m
3
/s) must
be no less than 2.2 m
3
/s (4661.5 CFM) to limit the temperature rise inside the
building to 10 °C (18 °F) above the outside temperature. With that air flow, the
maximum allowable outside ambient temperature is therefore 35 °C (95 °F) to
avoid derating or 40 °C (104 °F) to avoid over-temperature shutdown.
If air conditioning is planned, the heat load of the Xantrex GT500 is 27.5 kW
(68600 BTU/hour) at full load. Inverter assembly heat loss is 20.5 kW and
transformer assembly heat loss is 7.0 kW.
Location The Xantrex GT500 is designed and certified for both indoor and outdoor
installation. Anchor the Xantrex GT500 to a level concrete floor or pad or to
another non-combustible surface. The concrete floor or pad upon which the
Xantrex GT500 is anchored must be structurally designed to meet any local,
state, or national requirements for weight, seismic, and wind shear, if applicable.
If the Xantrex GT500 will be installed on or over a combustible surface, then the
installer must provide and install a metal barrier completely covering the bottom
of both the inverter and transformer assemblies.
The Xantrex GT500 can be placed over a foundation hole that holds the cables or
placed on top of a hollow platform that allows access to the bottom of the unit.
The Xantrex GT500’s cabinet meets UL 50 for Type 3R enclosures and is not
intended for use in the presence of extreme weather conditions; in the presence
of highly corrosive, industrial chemicals; or in hazardous locations.
DANGER
HAZARD OF CRUSH
• Make sure the mounting surface is properly designed to support the weight
of the Xantrex GT500.
• The width and depth of the pad must be the same size as the Xantrex
GT500. The flatness of the mounting surface must be no more than
2.5 mm/m (0.1 in./40 in.).
Failure to follow these instructions will result in death or serious injury.
