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 connect the CAN-H,L,GND only and do not connect other pins to in
-
verter.

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 mod
-
ule 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. Solution:
to move battery to the normal operating temperature range between 0
°C
and 50
°C
c) Current: If current exceeds 90A, battery protection will turn on.
