Instructions:
5 # parallel positive pole line, 6 # parallel negative pole line and 7 # parallel
communication line are only needed in parallel operation mode of battery module.
Battery module is not needed in single-machine operation mode.
The number of these three cables is equal to the number of battery parallel machines
minus one. For example, when users use two modules in parallel, you need to use one 5
# parallel positive polar line, one 6 # parallel negative pole line and one 7 # parallel
communication line .

5.Electrical Interface
1. Battery+, Battery- port
The battery pack has two batteries output interfaces, distributed on the left side of the
battery panel, which are Power+ and Power-. These two interfaces belong to the parallel
relationship in the internal and electrical connection of the battery. Connected to the
inverter, the battery pack can be charged or discharged.

2. Communication port
Two sets of 2PIN sockets are used in the battery pack. RS485 signal is in the socket.
RS485-1 and RS485-2 have the same function.
Two sets of 2PIN sockets are used in the battery pack. There are CAN signals in the
sockets. CAN-1 and CAN-2 have the same functions.
The CAN_H and CAN_L in the socket are connected with the inverter. They follow the
CAN protocol and are used to transmit the information and data of the battery. The CAN
matching resistor is required to installed on the device side.
RS485A and RS485B in the socket can be connected with PC computer, and follow the
RS485 protocol for battery package monitoring or firmware upgrade.
