7.1.2Ethernet port
The monitoring panel integrates Ethernet port with position numbered as J25. 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 storage inverter are connected to the
switch, and the switch is connected to remote control computer. The state of storage inverter can be monitored and
controlled in real time by setting IP address and port number in the monitoring computer.
