-PWS2-30K-NA has two different communication interfaces: Ethernet and RS-485.
+PWS2-30K-NA has two different communication interfaces: Ethernet and RS-485, meanwhile, there is a remote emergency power off terminal.

  ===== Ethernet cable connection =====
-PWS2-30K-NA can be directly networked through Ethernet and connected to PC for communication. Through networking, users can remote dispatch energy, monitor operation state, and set parameters with background software in PC.
+PWS2-30K-NA can be directly controlled through Ethernet for remote control. Through networking, users can remote dispatch energy, monitor operation status, and set parameters with MODBUS TCP/IP protocol.

-(2) RS 485 cable connection
+====== RS-485 cable connection ======
-PWS2-30K-NA can be connected to EMS through RS-485 to obtain battery information and energy dispatching command and complete automatic charging and discharging control and protection of energy storage system. RS-485 is connected through RJ45 connector. The definition of the pin of RJ45 connector is shown in Fig. 3 19. The connection steps are the same as Ethernet cable.
