The inverter must be mounted plumb and level when viewed from the front and may be tilted
up to five (5) degrees when viewed from the side. The wiring box must always face down.
Figure 4-1: Inverter orientation
All clearances specified in
“Clearances” on page 21
or greater must be available once the
inverter is mounted.
All mounting hardware must meet applicable building codes and be capable of supporting the
full weight of the inverter.
Avoid installation on resonating surfaces (light construction walls, etc.).
Avoid exposure to direct sunlight to eliminate thermal de-rating caused by high
temperatures.
Avoid exposing the inverter to ambient temperature exceeding -4°F to +113°F (-20°C to
+45°C) for optimal PV system efficiency. Temperatures beyond this range may cause thermal
de-rating or loss of inverter function.
Avoid exposure to water or heavy soiling, even though the inverter conforms to NEXA 4X and
IP67 requirements.
Choose a mounting height that allows easy viewing and access to the LED lights, LCD display,
and buttons on the inverter while meeting all clearance requirements.
CAUTION: FAILURE TO ENSURE ADEQUATE CLEARANCE ON ALL SIDES MAY
CAUSE THE INVERTER TO OVERHEAT.
