6. Trouble shooting
Communication related problem
Unable to communicate with inverter on compatible list.
Possible conditions:
1) RS485: baud rate. Check the dip switch1, set to correct one, and restart. All
master battery shall be the same.
2) CAN: terminal resistance. Check the dip switch2, set to 0 and retry.
3) CAN: pin. Try connects the CAN-H, L, GND only and do not connect other
pins to inverter. Using the correct cable.
Functional related problem
1) Whether the battery can be turned on or not
2) If battery is turned on, check the red light is off, flashing or lighting
3) If the red light is off, check whether the battery can be charged/discharged
or not.
Possible conditions:
1) Battery cannot turn on, switch ON and press the red SW the lights are all no
lighting or flashing.
a) Capacity too low, or module over discharged.
solution: use a charge or inverter to provide 48-53.5V voltage. If battery can
start, then keep charge the module and use monitor tools to check the
battery log.
If battery terminal voltage is ≤45Vdc, please use ≤0.05C to slowly charge
the module to avoid affect to SOH. If battery terminal voltage is >45Vdc, it
can use ≤0.5C to charge.
If battery cannot start, turn off battery and repair.
2) The battery can turn on, but red light is lighting, and cannot charge or
discharge. If the red light is lighting, that means system is abnormal, please
check values as following
b) Temperature: Above 60°C or under -10°C, the battery could not work.
