System Debug
This system debug is for BESS system (Battery Energy Storage System). BESS system can’t do the
debug itself. It must operation with configured inverter, UPS, PCS and EMS system together.
Debug Step
Content
Prepare of debug.
Turn on the BESS system, refer to chapter 3. Before turn on the whole
BESS system turn on the load is
not allowed!
Remark: Except the BESS, if other equipment have its own system turn
on step, must follow the operation manual.
Working together with
inverter
1) Check the communication cable connection and make sure the
cable order on battery and inverter side are matched. All undefined
pin are suggested to be empty.
2) Check the baud rate of inverter. The default of battery CAN is
500kbps, MODBUS 485 is 9600bps. If necessary, change the baud rate
of RS485.
3) Check the terminal resistance CAN 120 Ω, 485 120 Ω
4) If necessary, check the setting on inverter or control box has right
parameter and brand of battery. And check the information of BESS
shown on inverter is correct.
