Communication
1.Communication connection between the batteries
Use standard Ethernet cables to connect the battery communication ports. Connect the IN port of the higher-level battery to the OUT port of the lower-level battery. The highest-level battery is the master battery, and the other batteries are slave batteries.
2.Communication cable connection between the master battery and the inverter
Connect the OUT port of the master battery to the inverter's BMS interface using a communication cable. Since different inverters have different BMS interfaces, the communication cables used may vary.
Pls check manual to get different version cable
3.Communication with PC to batteries
This is used for checking battery information. Insert the RJ45 plug of the included RS485 to USB communication cable into the OUT port of the master battery (remove the communication plug connected to the inverter first, if necessary). Insert the USB plug of the communication cable into the computer's USB port. After installing the corresponding communication cable driver, you can run the software to monitor the battery or upgrade the firmware (please refer to the corresponding manual for detailed software operation) .
You can buy the RS485 cable from RUiXU or you can make the cable yourself.
