securely disconnected during maintenance and fully protected from over current of battery or AC input. The
recommended mounted location of the breakers is shown in the parallel diagrams in section 5-1 and 5-2.
Recommended specification of battery breaker for each inverter:
Model 1 unit*
3KVA 125A/30VDC
*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 specification of AC input breaker in single phase:
Model
2 units 3 units 4 units 5 units 6 units
3KVA 80A/230VAC 120A/230VAC
160A/230VAC 200A/230VAC 240A/230VAC
Note 1: You also can use only one 40A breaker for each inverter at its AC input.
Note 2: Regarding three-phase system, you can use 3-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 2 3 4 5 6
Battery Capacity 200AH 300AH 400AH 500AH 600AH
WARNING! Be sure that all inverters will share the same battery bank. Otherwise, the inverters will be
transferred to fault mode.
