2.1 Selecting a Location for the Inverter and

Integrated AC/DC Disconnect

When choosing a location for the inverter/disconnect unit, consider the

following criteria:

• The unit is suitable for both indoor and outdoor installation; the in-

verter and disconnect enclosures have a NEMA 3R rating.

• The optimum location of the unit is outside, shielded from direct expo-

sure to sunlight (i.e. not on the south facing side of the building).

• The heat sink temperature can exceed 158°F (70°C). The unit should

be installed so people cannot touch the top of the inverter.

• The inverter is designed and tested to produce maximum continuous

output power within the ambient temperature range of -15°F to 105°F

(-25°C to 40°C).

Location and Clearances

The following clearances are recommended for proper placement of the

unit:

• A minimum of 36” (91.5 cm) between the bottom of the Integrated

AC/DC Disconnect box and the ground.

• A minimum of 12” (30.5 cm) above the heat sink.

• Approximately .5” (1.25 cm) of width clearance on the right and left

sides of the unit’s cabinet.

Visibility of the operating LEDs and display located at the top front of the

inverter box should also be considered. Refer to Figure 2-1 for the location

of the LED and display.

If the unit is installed in an enclosed space, adequate ventilation must be

provided.

2.2 Guidelines for Mounting the Inverter and

Integrated AC/DC Disconnect

The inverter/disconnect unit should be mounted vertically to a at, solid

surface such as strut, concrete, or wood siding. It should be located near

the PV arrays to minimize the DC conductor length.

The provided bracket and paper mounting template make mounting the

unit quick and simple.

The small bracket:

• Has a vertical row of screw holes down the center and is designed for a

single-stud mount. Refer to Figure 3-1.
