Inverter Location

Inverter failure due to improper installation will void the inverter warranty.

Consider the following when determining where to install the inverter.

WARNING: Burn hazard
Do not install in a location where people can accidentally come into contact with the front
of the inverter. High temperatures can be present on the face of the inverter, causing a
potential burn hazard.
In extreme condition s, the GT In v er ter chassis can reach temperatures over 70°C (158°F),
which can cause skin burns if accidentally touched. Ensure that the GT Inverter is located
away from normal traffic areas.
Fire Safety Do not install anywhere near combustible or flammable materials.
Indoor/Outdoor The GT Inverter uses a Type 3R-rated enclosure (vertical mount
only) that can be mounted indoors or outdoors. (Type 3R
enclosures are intended for outdoor use primarily to provide a
degree of protection against falling rain; and to be undamaged by
the formation of ice on the enclosure.)
While the 3R-rated enclosure protects the GT Inverter from
moisture, outdoor installations should be located away from lawn
sprinklers and other sources of spray.
Orientation The GT Inverter must be mounted vertically on a wall or pole.
Do not mount the GT Inverter horizontally.
Temperature Ensure that the GT Inverter is mounted i n a location wh ere the
ambient temperature rang e is -25° to +65° C (-13° to +149° F).
At extreme hot or cold temperatures, the front panel LCD may not
function normally. Above 45° C (113° F), the unit begins derating
power. See Environmental Specifications on pageA5 and
Output Power vs. Ambient Temperature on page A3.
Ground
Clearance
Outdoors, the GT Inverter requires at least 100 cm (39 inches) of
clearance between the bottom of the unit and the ground.
Indoors, it is recommended that the same clearance between the
bottom of the unit and the floor be used.
Distance To minimize copper losse s, ensure that wire lengths between the
PV array and the GT Inverter and between t h e in verter and the
Main Utility Service Panel are kept to a minimum.
Maximum distances will depend on wire gauges used and PV
array output voltages.
Debris free Excessive debris (e.g., dust, leaves, cobwebs) can accumulate on
the unit, interfering with wiring connections and ventilation. Do
not install in a location where debris can accumulate (such as
under a tree).
