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
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
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.
