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 conditions, the GT Inverter 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 in a location where the
ambient temperature range 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 page A–5 and
“Output Power vs. Ambient Temperature” on page A–3.
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 losses, ensure that wire lengths between the
PV array and the GT Inverter and between the inverter 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).
