2. Site Preparation and Inverter Placement
The inverter is comprised of a NEMA 3R enclosure containing electrical and electronic
components and AC and DC integrated disconnects.
NOTE:
If the inverter is mounted outside, ensure that the enclosure remains closed during
the installation process in case of rain or snow. Leaving the cover off during installation will
void the warranty. Only the wiring box cover should be removed during wiring. The inverter
section cover remains on at all times.
NOTE:
It is recommended to store the inverter indoors before installation.
If the inverter is
to be stored outdoors before being installed and commissioned, care must be taken to
avoid condensation inside the unit.
2.1 Criteria for device mounting:
Because the power electronics are within the rainproof enclosure, the inverter can be
mounted outdoors.
The maximum life for the inverter can be achieved by mounting the unit in a clean, dry and
cool location.
For optimal electrical system efficiency, use the shortest possible AC and DC cables and use
the maximum allowable cable size.
Install the inverter in an accessible location following local electric codes for enclosure
proximity to other equipment.
Although the inverter is designed to function at full power continuously up to 50
o
C ambient
temperature, for optimal inverter life and performance, do not mount the inverter in direct
sunlight, especially in hot climates. If the unit must be mounted in direct sunlight a sun-shield
is recommended but not reqiured. It is recommended that the inverter is mounted on the
north side of buildings or on the north side of a ground mount PV array.
CAUTION:
Please follow these guidelines:
Be sure to verify load capacity of wall or mounting area where the inverter would be
mounted.
