36
5KVA 2*4AWG 5~ 6 Nm
Recommended cable size of AC input and output for each inverter:
Model AWG no. Torque
5KVA 10 AWG 1.4~1.6Nm
You need to connect the cables of each inverter together. Take the battery cables for example: You need to use
a connector or bus-bar as a joint to connect the battery cables together, and then connect it to the battery
terminal. The size of the cable used from joint to battery should be X times cable size in the tables above. “X”
indicates the number of inverters connected in parallel.
Regarding AC input and output, please also follow the same principle.
CAUTION!! Please install the breaker at the battery and AC input side. This will ensure the inverter can be
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*
5KVA 125A/80VDC
*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
5KVA 80A/230VAC 120A/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
Battery Capacity 400AH 600AH
WARNING! Be sure that all inverters will share the same battery bank. Otherwise, the inverters will be
transferred to fault mode.
