2.2 Mounting the SunPower Inverter
The SunPower Inverter should be mounted vertically to a flat, solid surface such as wallboard,
concrete or wood siding. The inverter should be located in close proximity to the solar panels
to minimize the DC wire length. The mounting bracket provided makes mounting the SunPower
Inverter quick and simple. The two screw holes at either end of the bracket are 16 inches
apart. Once the wall studs are located, anchoring the bracket becomes an easy task.
WARNING: Prior to drilling holes to mount the SunPower Inverter in the location
selected; ensure there are no electrical wires or plumbing in the area.
CAUTION:
The National Electrical Code (NEC) requires that the inverter be connected to a dedicated
circuit with no other outlets or devices connected to the same circuit. See NEC Section 690-
64(b)(1). The NEC also places limitations on the size of the inverter and the manner in which it
is connected to the utility grid. See NEC Section 690-64(b) (2).
2.2. A Steps to Mount the SunPower Inverter
1. Locate the wall studs in the desired location and align the mounting bracket over the
studs. Mark the mounting holes. Ensure that locations A and B (as indicated in Figure 1
below) are aligned over the wall studs.
2. MAKE SURE BRACKET IS LEVEL. Ensure points A and B are aligned with wall studs.
Drill 1/8”pilot holes for the screws. Use heavy-duty ¼” x 2”coarse thread lag screws to
secure points A and B to the wall. Use an 1/8” screw to secure point C. See Figure 1.
