Communication connection
PWS2-30K-NA has two different communication interfaces: Ethernet and RS-485.
Ethernet cable connection
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.
- Penetrate network cable whose insulating layer is stripped into the waterproof cap and insert it into RJ45 connector after being arranged in order;
- Use wire crimpers to compress the connector;
- Screw out the cap on the waterproof Ethernet terminal at the bottom of the inverter;
- Insert the ready-made cable into Ethernet terminal.
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.
Remote EPO connection
A remote EPO switch can be connected to the R-EPO RJ45 port.
THE R-EPO IS A NORMAL CLOSED CONTACT.IT SHOULD BE CONNCTED TO A NC SWITCH OR BUTTON. IF NO REMOTE EPO IS NEEDED, PLEASE DISABLE THE EPO FUNCTION IN HMI.
