inverter (or the junction box) with a red and black cable respectively.
 Multiple batteries (Max number 8):
The connection of several batteries is only permitted in parallel.
Firstly, connect the positive poles with the supplied red cables, and
connect the negative poles with the supplied black cables. Next
connect the positive and negative poles of the battery to the positive
and negative poles of the DC port of the hybrid inverter (a storage
device or a junction box) with a red and black cable.
The standard battery current is the same no matter how many
batteries are paralleled refer to the "Table1-1". Bus bar should be
applied when higher current (>100A) is needed for specific projects.
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 you hear a "Click" sound, 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 to a
Bus-Bar.
