Recommended AC input and output cable size for each inverter:

Model

AWG no.

Torque

4KVA

10 AWG

1.4~1.6Nm

5KVA

8 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 to the battery

terminal. The cable size 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 figures in 5-1 and 5-2.

Recommended breaker specification of battery for each inverter:

Model

1 unit*

4KVA

80A/60VDC

5KVA

100A/60VDC

*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:

Model

2 units

3 units

4 units

5 units

6 units

4KVA

80A/230VAC

120A/230VAC

160A/230VAC

200A/230VAC

240A/230VAC

5KVA

100A/230VAC

150A/230VAC

200A/23VAC

250A/23VAC

300A/23VAC

Note1: Also, you can use 40A breaker (50A for 5KVA) for only 1 unit, and each inverter has a breaker at its AC

input.

Note2: Regarding three phase system, you can use 4 poles breaker, the rating is up to the current of the

phase which has the maximum units. Or you can follow the suggestion of note 1.

Recommended battery capacity

Inverter parallel numbers

Battery Capacity

400AH

600AH

800AH

1000AH

1200AH

WARNING! Be sure that all inverters will share the same battery bank. Otherwise, the inverters will transfer

to fault mode.
