Recommended breaker specification of battery for each inverter:
Model
1 unit*
OGX 5.48a
135A/70VDC
*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.

Note1: Also, you can use 50A breaker for only 1 unit and install one breaker at its AC input in each inverter.
Note2: 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
