d) High Voltage: If charging voltage above 54V, battery protection will turn on.
Solution: Check whether voltage is too high or not, if it is, to change the
settings on power supply side. And discharge the module.
e) Low Voltage: When the battery discharges to 44.5V or less, battery
protection will turn on.
Solution: Charge the battery till the red light turns off.
f) Cell voltage high. The module voltage is lower than 54V, SOC LED does
not all on. When discharge the module protection disappear.
Solution: keep charge the module by 53-54V or keep the system cycle. The
BMS can balance the cell during cycling.
3) Unable to charge and discharge with red LED on. The temperature is 0~50
degree. Use charger to charge, not possible. Use load to discharge, not
possible.
g) Under permanent protection. The single cell voltage has been higher than
4.2 or lower than 1.5 or temperature higher than 80 degree. Solution: Switch
off the module and contact your local distributor for repair.
4) Unable to charge and discharge without red LED on. The temperature is
0~50 degree. Use charger to charge, not possible. Use load to discharge,
not possible.
h) Fuse broken.
Solution: Switch off the module and contact your local distributor for repair.
5) Buzzer rings.
i) Reverse connection of cables.
Solution: Power off all battery and inverters. Disconnect breaker. Check the
cable connection and disconnect all power cables. Check the power port
damaged or not.
