WARNING: 

Be sure the length of all battery cables is the same. Otherwise, there will be voltage difference 

between inverter and battery to cause parallel inverters not working.   

 

 

Recommended AC input and output cable size for each inverter: 

 

Model  

 

AWG no. 

 

Torque 

 

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 sections 5-1 and 5-2.  

Recommended battery breaker specification for each inverter:

  

Model  

One unit*  

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 AC input breaker specification for single-phase application:

  

 

Note 1:

 It’s accepted to use 50A breaker for each unit in parallel system and each inverter should be installed 

a breaker in the AC input.  

Note 2:

 In three-phase parallel system, you can use one 4-pole breaker. The accepted breaker rating is based 

on the phase current with the maximum units. Otherwise, please follow note 1 instruction.
