terminals of adjacent batteries with the red cable; and the two
negative terminals of adjacent batteries with the black cable; then
connect the positive and negative terminal of the battery with the
positive terminal of the DC port of the energy storage inverter (or the
junction box) with a red and black cable respectively;
The capacity can be increased by connecting the batteries in
parallel, but due to the limitations of BMS and power cable we
supply, only two batteries can be connected in parallel and a bus
bar should be used for connecting them together.
Warning: Batteries connected in series are forbidden, high voltage would lead
to hazard shock.
2. Power cable connection instructions of Multi-Rack:
Collect the positive and negative power cables respectively by the
bus bar or junction box, then connect two racks in parallel.
The length, thickness, material, and resistance of the cables
connected in parallel must be the same.
Note: When the cable is inserted into the positive and negative
terminals of the battery and “Click”, the cable is firmly connected.
Before pulling out the cable, press the small button next to the terminal.
When multiple batteries are connected in parallel, in order to reduce
the influence of the circular current, the overall positive and negative
output cables can be connected from different batteries.
