When installing DC cables:

Note minimum sizes in Table 4, but refer to local codes for absolute cable size recommendations.

Battery positive and negative cables should be no longer than 3 meters (10 feet) each, to minimize voltage loss and other effects.

Always install breakers or fuses on the positive cable.

The cables listed above are for each inverter in a system. In a system with multiple inverters, each inverter requires its own cables and breakers of the size indicated.

The inverter’s battery terminal is a threaded stud which accepts a ring terminal lug. Use crimped and sealed copper ring lugs with 0.79 cm (5/16 in) holes, or use compression lugs.

Tie, tape, or twist cables together to reduce self-inductance. Run positive and negative cables through the same knockouts and conduit.

Make certain the DC breaker is turned to the off position, or the fuse is removed, before proceeding.

If present, remove the battery terminal covers. These are made of stiff plastic with a snap-on design. Remove carefully using a flat screwdriver inserted into the slots on the sides of each cover.
