Inverter Location

Installation

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.

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

Consider the following when determining where to install the inverter.

•Do not install anywhere near combustible or flammable materials.

•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.

•The GT Inverter must be mounted vertically on a wall or pole.

•Do not mount the GT Inverter horizontally.

•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.

•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.

•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.

•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).
