Chapter 5 Communication mode
5.1 Communication interface
PWS2-30M-EX supports Modbus protocol, adopts RS-485 and Ethernet communication
interface and facilitates users to conduct background monitoring for energy storage inverter
and realize remote signaling, remote metering and remote regulating of energy storage
inverter.
5.1.1 RS-485 interface
RS-485 interface is reserved at the bottom of PWS2-30M-EX and used to communicate
with EMS. As an energy dispatching unit for energy storage system, EMS accepts remote
dispatching, receives BMS information and realizes control and protection of automatic
charging and discharging of energy storage system.

5.1.2 Ethernet interface
PWS2-30M-EX supports Modbus TCP/IP protocol and has its own IP address. It can
connect the Ethernet ports of multiple energy storage inverters to the switch, and the switch
is connected to remote control computer or EMS. Thus, the state of energy storage inverter
can be monitored and controlled in real time.
