7.1.2 Ethernet port
The monitoring panel integrates Ethernet port with position numbered as RJ25. It supports Modbus TCP/IP protocol and has
its own IP address like a PC. Ethernet connection requires a switch, and fixed IP needs to be set. Connecting cables are
twisted pair (namely network cable). The internet ports of multiple The storage inverter are connected to the switch, and the
switch is connected to remote control computer. The state of the storage inverter can be monitored and controlled in real time
by setting IP address and port number in the monitoring computer.

7.1.3 Communication with BMS
The inverter communicates with battery management unit (BMS) to monitor battery state information, give an alarm and
provide fault protection for battery according to the battery state and improve the safety of storage battery. It supports CAN
communication. In particular, the position number of CAN communication interface in the monitoring panel is J23. It is led to
terminal strip ports 7 and 8.
