5. System Debug
This system debug is for BESS
(Battery Energy Storage System). BESS debug can’t be performed alone. It must be operated with
configured inverter, UPS, PCS and EMS system together.
Preparations for debug.
Turn on the BESS, referring to Section 4. It is
to turn on the
load before turning on the whole BESS.
Remark: Except the BESS, if other equipment has its own system power on
procedure, be sure to follow its specific 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 pins are
suggested to be empty.
(2) Check the baud rate of inverter. The default value 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
parameters and brand of battery. And check the information of BESS
shown on inverter is correct.
