Recommended breaker specification of battery for each inverter:
*If you want to use only one breaker at the battery side for the whole system, the rating of the breaker
should be X times current of 1 unit. “X” indicates the number of inverters connected in parallel.
Recommended breaker specification of AC input with single phase:
Note 1: Also, you can use 60A breaker with only 1 unit and install one breaker at its AC input in each
inverter.
Note 2: Regarding three-phase system, you can use 4-pole breaker directly and the rating of the breaker
should be compatible with the phase current limitation from the phase with maximum units
Recommended battery capacity
Inverter parallel numbers
WARNING! Be sure that all inverters will share the same battery bank. Otherwise, the inverters will transfer
to fault mode.
