Notes regarding mounting and placement of the inverter.
Criteria for device mounting:
•
Because the power electronics is in an IP65 sealed enclosure within the NEMA 3R main
enclosure, the inverter can be mounted outdoors.
•
The very longest life for the inverter can be achieved by mounting it in a clean, dry and cool
location even given the unit’s robust construction and powerful cooling system.
•
For optimal electrical 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 a small amount of high-
frequency switching noise.
•
Install the inverter in an accessible location following NEC codes for enclosure and
disconnect door clearances and proximity to other equipment. (See mounting diagram, Fig.
2.2a & 2.2b)
•
Although not required, installation at eye- height allows easy reading of the indicator LEDs
on the right side of the inverter above the DC (PV) disconnect.
•
For optimal inverter life and performance, do not mount the inverter in direct sunlight,
especially in hot climates, although the inverter is designed to function at full power
continuously in up to 45
o
C ambient temperatures. In hot climates if the unit must be
mounted in direct sunlight a metal sun-shield is recommended. It is recommended that the
inverter is mounted on the north side of buildings or on the north side of a PV array (which
can provide some shade).
CAUTION:
Please follow these guidelines:
•
The inverter weight is 380 lbs. Be sure to verify load capacity of floor, roof or wall
mounting area.
•
The ambient temperature must be between –20
o
C and +45
o
C for full power, continuous
operation. (The inverter will automatically reduce power or shut down to protect itself if
ambient air temperature rises above 45
o
C.)
•
The National Electrical Code (NEC) requires that the inverter be connected to a dedicated
circuit and no other outlets or device may be connected to this circuit. See NEC Section 690-
64(b)(1). The NEC also imposes limitations on the size of the inverter and the manner in
with it is connected to the utility grid. See NEC Section 690-64(b)(2).
