Battery12 codesFAULT (RED ON, LED1=OFF, LED2=OFF, LED3=OFF, LED4=ON)BMS TEMPERATURE LOW.Fault
BMS internal temperature fell below the lower protection threshold.
Warm the installation environment (operating range Charge: 0°C–55°C, Discharge: -20°C–55°C). The fault will self-clear once temperature returns to range. if the fault persists, contact the local distributor.
LUX-E-48100LG04-Lithium-Battery-User-Guide.pdf · page 12FAULT (RED ON, LED1=OFF, LED2=OFF, LED3=ON, LED4=OFF)CELL VOLTAGE LOW.Fault
An individual cell voltage fell below the lower cell protection threshold.
Recharge the battery promptly. The BMS will self-recover once cell voltage recovers. if the fault persists, contact the local distributor.
LUX-E-48100LG04-Lithium-Battery-User-Guide.pdf · page 12FAULT (RED ON, LED1=OFF, LED2=ON, LED3=OFF, LED4=OFF)BATTERY VOLTAGE LOW.Fault
Total battery pack voltage fell below the BMS lower protection threshold (undervoltage protection).
Recharge the battery promptly (per section 10.1, the battery should be charged in time when undercharged or stored more than 3 months). The BMS will automatically return to normal once voltage recovers. if the fault persists, contact the local distributor.
LUX-E-48100LG04-Lithium-Battery-User-Guide.pdf · page 12FAULT (RED ON, LED1=OFF, LED2=ON, LED3=OFF, LED4=ON)CELL TEMPERATURE LOW.Fault
An individual cell temperature fell below the lower protection threshold (charge: below 0°C; discharge: below -20°C).
Warm the environment until cells are within the operating range (Charge: 0°C–55°C, Discharge: -20°C–55°C). The fault will self-clear once temperature normalises. if the fault persists, contact the local distributor.
LUX-E-48100LG04-Lithium-Battery-User-Guide.pdf · page 12FAULT (RED ON, LED1=OFF, LED2=ON, LED3=ON, LED4=OFF)DISCHARGING CURRENT HIGH.Fault
Discharging current exceeded the BMS overcurrent protection threshold.
Reduce load current; verify the load is within the recommended 50A and max-continuous 60A limits (peak 100A for 15s). The BMS will self-recover once current returns to normal. if the fault persists, contact the local distributor.
LUX-E-48100LG04-Lithium-Battery-User-Guide.pdf · page 12FAULT (RED ON, LED1=ON, LED2=OFF, LED3=OFF, LED4=OFF)BATTERY VOLTAGE HIGH.Fault
Total battery pack voltage exceeded the BMS upper protection threshold (overvoltage protection).
Stop charging and allow voltage to drop. The BMS will automatically return to normal once the trigger condition is removed. if the fault persists, contact the local distributor.
LUX-E-48100LG04-Lithium-Battery-User-Guide.pdf · page 12FAULT (RED ON, LED1=ON, LED2=OFF, LED3=OFF, LED4=ON)CELL TEMPERATURE HIGH.Fault
An individual cell temperature exceeded the upper protection threshold.
Stop charging/discharging and allow the cell to cool; check ambient temperature is within the operating range. The fault will self-clear once temperature normalises. if the fault persists, contact the local distributor.
LUX-E-48100LG04-Lithium-Battery-User-Guide.pdf · page 12FAULT (RED ON, LED1=ON, LED2=OFF, LED3=ON, LED4=OFF)CHARGING CURRENT HIGH.Fault
Charging current exceeded the BMS overcurrent protection threshold.
Reduce charging current; verify charger/inverter is configured within the recommended 50A and max-continuous 60A limits (peak 100A for 15s). The BMS will self-recover once current returns to normal. if the fault persists, contact the local distributor.
LUX-E-48100LG04-Lithium-Battery-User-Guide.pdf · page 12FAULT (RED ON, LED1=ON, LED2=ON, LED3=OFF, LED4=OFF)CELL VOLTAGE HIGH.Fault
An individual cell voltage exceeded the upper cell protection threshold.
Stop charging and allow the affected cell voltage to drop. The BMS will self-recover once the trigger condition is removed. if the fault persists, contact the local distributor.
LUX-E-48100LG04-Lithium-Battery-User-Guide.pdf · page 12FAULT (RED ON, LED1=ON, LED2=ON, LED3=OFF, LED4=ON)CURRENT SENSOR ABNORMAL.Fault
BMS detected an abnormal reading from the current-sampling circuit / current sensor.
Restart the battery (turn breaker OFF then ON, press POWER for 1 second). if the fault persists, contact the local distributor (per section 10.2: when the LED does not light up or flash on power-up, consider contacting the local distributor).
LUX-E-48100LG04-Lithium-Battery-User-Guide.pdf · page 12FAULT (RED ON, LED1=ON, LED2=ON, LED3=ON, LED4=OFF)BMS TEMPERATURE HIGH.Fault
BMS internal (MOSFET / control board) temperature exceeded the upper protection threshold.
Check the ambient temperature and cooling space around the unit (per section 8.3 ambient must be 0°C–45°C). Allow the BMS to cool. The fault will self-clear once temperature returns to range. if the fault persists, contact the local distributor.
LUX-E-48100LG04-Lithium-Battery-User-Guide.pdf · page 12LOW POWER (GREEN FLASH, RED OFF, all LEDs OFF)Low Power / Low SOC shutdown.Fault
Battery state-of-charge is critically low and the system has entered low-power state with output disabled.
Recharge the battery. Per section 10.1, charge the battery in time if it is often under-charged or has been stored for more than 3 months. The system will return to normal once charging restores SOC.
