Warm the battery to within the operating range before resuming use. Do not install in environments below 0 degC.
Felicitysolar LPBF24200-M LiFePO4 Battery System for Households User Guide.pdf · page 9FAULT: LED1=OFF, LED2=ON, LED3=ON, LED4=OFF (Green OFF, Red ON)Discharging Current High.Fault
Discharge over-current protection has tripped; output is disabled.
Connected load drew more current than the recommended discharge limit (≤80 A) or sustained the 120 A 15 s peak too long, or a short-circuit on the DC bus.
Remove or reduce the load, check for short circuits on the output wiring, and restart the pack. For loads above 6 kVA install at least 2 packs in parallel.

Pack over-voltage protection has tripped; output is disabled.
Pack voltage exceeded the BMS over-voltage protection threshold during charging.
Disconnect the charging source, verify charge-voltage settings, and allow the pack voltage to fall before re-enabling output.
Felicitysolar LPBF24200-M LiFePO4 Battery System for Households User Guide.pdf · page 9FAULT: LED1=ON, LED2=OFF, LED3=OFF, LED4=ON (Green OFF, Red ON)Cell Temperature High.Fault
Cell pack over-temperature protection has tripped.
Cells heated above the safe operating temperature (charging range 0-55 degC, discharging range -20-60 degC per spec).
Stop charging/discharging, let the pack cool, and improve ventilation. if the fault persists at normal ambient, contact the supplier.
Felicitysolar LPBF24200-M LiFePO4 Battery System for Households User Guide.pdf · page 9FAULT: LED1=ON, LED2=OFF, LED3=ON, LED4=OFF (Green OFF, Red ON)Charging Current High.Fault
Charging over-current protection has tripped.
Charge current exceeded the recommended limit (e.g. >80 A on LPBF24200-M / LPBF48200-M/P) or the 15 s 120 A maximum for too long.
Reduce the charge current at the charger / inverter to within the recommended setting in section 2.4. For systems above 6 kVA at least 2 packs in parallel are required.
Felicitysolar LPBF24200-M LiFePO4 Battery System for Households User Guide.pdf · page 9FAULT: LED1=ON, LED2=ON, LED3=OFF, LED4=OFF (Green OFF, Red ON)Cell Voltage High.Fault
One or more individual cells have exceeded the upper cell-voltage protection limit.
Cell imbalance during charging, or a charger setting that allows individual cells to drift above their safe ceiling.
Stop charging, allow the BMS to balance, and review charger settings. if the condition persists the pack may need service.
Felicitysolar LPBF24200-M LiFePO4 Battery System for Households User Guide.pdf · page 9FAULT: LED1=ON, LED2=ON, LED3=OFF, LED4=ON (Green OFF, Red ON)Current Sensor Abnormal.Critical
BMS current-sensor diagnostic failure; the pack cannot reliably measure charge/discharge current.
Internal current sensor fault or wiring problem on the BMS board (text in manual: 'CURRENT SENSOR ABNOMAL' [sic]).
Power-cycle the pack. if the fault persists do not continue to use the unit; contact a qualified service technician — section 1.3 warns that only qualified service persons may service the device.
Felicitysolar LPBF24200-M LiFePO4 Battery System for Households User Guide.pdf · page 9FAULT: LED1=ON, LED2=ON, LED3=ON, LED4=OFF (Green OFF, Red ON)BMS Temperature High.Fault
BMS / electronics over-temperature protection has tripped.
Insufficient ventilation around the unit, ambient temperature too high, or sustained high charge/discharge current.
Stop charging/discharging and let the unit cool. Improve ventilation and ensure the ambient temperature is within 0-45 degC for installation per section 3.2.
Felicitysolar LPBF24200-M LiFePO4 Battery System for Households User Guide.pdf · page 9LED1=OFF, LED2=ON, LED3=OFF, LED4=OFFBattery Voltage Low.Warning
Pack-level battery voltage is below the lower threshold (under-voltage / low-pack warning).
Excessive discharge or extended period without charging; pack approaching the cut-off voltage (24 V / 48 V).
Charge the battery as soon as possible from mains or PV. The manual warns repeatedly that an over-discharged pack may fail to be re-activated by normal AC/PV wake-up.
Felicitysolar LPBF24200-M LiFePO4 Battery System for Households User Guide.pdf · page 9LED1=ON, LED2=OFF, LED3=OFF, LED4=OFFBattery Voltage High.Warning
Pack-level battery voltage is above the upper threshold (over-voltage warning at the pack level).
Charger output voltage above the pack maximum charging voltage (e.g. >28.8 V on the 24 V model, >57.6 V on 48 V models).
Stop charging and check the charger / inverter charge-voltage settings against the recommended values in section 2.4. Resume only after the pack voltage falls back into the operating range.
