Communication connection

PWS2-30K-NA has two different communication interfaces: Ethernet and RS-485.

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.

Ethernet interface

1. Penetrate network cable whose insulating layer is stripped into the waterproof cap and insert it into RJ45 connector after being arranged in order;
2. Use wire crimpers to compress the connector;
3. Screw out the cap on the waterproof Ethernet terminal at the bottom of the inverter;
4. Insert the ready-made cable into Ethernet terminal.

(2) 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.

The wiring making of RS-485 is the same as Ethernet cable. RJ45 terminal should be inserted into RS-485 port and cap shall be locked.

(3) Remote EPO connection A remote EPO switch can be connected to the R-EPO RJ45 port.

The wiring making of R-EPO is the same as Ethernet cable. RJ45 terminal should be inserted into the port\.
