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.

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. “

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.
