This section describes the wiring requirements and considerations. It provides the
required wire sizes, recommended lengths for conductors, and disconnect/circuit
breaker requirements. All wiring should be made with minimum 90° C copper
wire. While 90°C or higher temperature rated wiring may be used, the wire gauge
sizing must still be based in accordance with 75°C wiring ampacities from your
local electrical code for use in conjunction with typical AC over-current
protection. See “Minimum Recommended Battery Cable Size versus Length” on
page 2–8 for details.
All wiring and installation methods should conform to applicable electrical and
building codes.
Pre-plan the wire and conduit runs.
•
The AC terminals accept cable sizes up to #6 AWG (13.6 mm
2
).
•
The DC terminals accept any size cables that use ring terminals with 5/16 in.
(8 mm) holes and a maximum flange width of 1 5/16 in. (33 mm).
•
If you intend to stack two 120 V/60 Hz units, consider the length of the
provided series stacking cable (3 ft./0.9 m).
•
Due to voltage drop considerations, battery-to-inverter cabling should be only
as long as required. See Table 2-4, “Minimum Recommended Battery Cable
Size versus Length” on page 2–8 to assist you with cable sizing and length.
For maximum safety, run both AC and DC cables in conduit.
