Installation and Operation Manual (Rev A)

2.0 Site Preparation and Inverter Placement

The inverter is comprised of a rainproof NEMA 3R industrial enclosure containing electrical and

electronic components.

NOTE: If the inverter is mounted outside, during the installation process and in case of

rain, do not open the inverter.

Criteria for device mounting:

• Because the inverter is in a NEMA 3R enclosure, the

inverter can be mounted outdoors.

• The longest inverter life can be achieved by mounting it in a clean, dry and cool location. It is

recommended to keep the unit out of direct rain or snow. Protection by a roof overhang or

covering is recommended if outdoor mounting is necessary.

• For optimal electrical system efficiency, use the shortest possible AC and DC cables and use

the maximum allowable cable size.

• Avoid installation in close proximity to people or animals, as there is an audible high-

frequency switching noise.

• Install the inverter in an accessible location following local codes. Note that code

requirements for clearances and proximity to other equipment and building walls apply.

• For optimal inverter life and performance, do not mo

unt the inverter in direct sunlight,

especially in hot climates. If the unit must be mounted in direct sunlight, a silver or white

metal sun-shield is highly recommended. It is further recommended that the inverter be

mounted on the north or east side of buildings or on the northern side of a ground mounted

PV array. Following these guidelines help prevent the unit from limiting the power produced

due to an excessively high inverter temperature.
