How to read the severity labels

  • Critical(1)— unit trips offline — do not restart before checking
  • Fault(10)— operation stops until cleared
  • Warning(2)— unit keeps running · needs attention

Critical codes (1)unit trips offline — do not restart before checking

FAULT: LED1=ON, LED2=ON, LED3=OFF, LED4=ON (Green OFF, Red ON)Critical

Current Sensor Abnormal.

Critical

BMS current-sensor diagnostic failure; the pack cannot reliably measure charge/discharge current.

CauseInternal current sensor fault or wiring problem on the BMS board (text in manual: 'CURRENT SENSOR ABNOMAL' [sic]).

Recommended fixPower-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.

BMS Temperature Low.

Fault

BMS / electronics under-temperature protection has tripped.

CauseAmbient temperature below the BMS operating range.

FAULT: LED1=OFF, LED2=OFF, LED3=ON, LED4=OFF (Green OFF, Red ON)Fault

Cell Voltage Low.

Fault

One or more individual cells have fallen below the lower cell-voltage protection limit.

CauseDeep discharge or a weak/aged cell pulling below the under-voltage threshold.

Recommended fixStop the load and recharge as soon as possible. if a single cell repeatedly trips the protection, contact the supplier for service.

FAULT: LED1=OFF, LED2=ON, LED3=OFF, LED4=OFF (Green OFF, Red ON)Fault

Battery Voltage Low (Fault).

Fault

Pack under-voltage protection has tripped; output is disabled.

CausePack voltage fell below the BMS under-voltage protection threshold during discharge.

Recommended fixStop the load immediately and recharge the battery as soon as mains or solar is available. Do not attempt repeated activation cycles on an over-discharged pack.

FAULT: LED1=OFF, LED2=ON, LED3=OFF, LED4=ON (Green OFF, Red ON)Fault

Cell Temperature Low.

Fault

Cell pack under-temperature protection has tripped.

CauseCell temperature below the allowed charging range (0 degC) or discharging range (-20 degC).

Recommended fixWarm the battery to within the operating range before resuming use. Do not install in environments below 0 degC.

FAULT: LED1=OFF, LED2=ON, LED3=ON, LED4=OFF (Green OFF, Red ON)Fault

Discharging Current High.

Fault

Discharge over-current protection has tripped; output is disabled.

CauseConnected 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.

Recommended fixRemove 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.

FAULT: LED1=ON, LED2=OFF, LED3=OFF, LED4=OFF (Green OFF, Red ON)Fault

Battery Voltage High (Fault).

Fault

Pack over-voltage protection has tripped; output is disabled.

CausePack voltage exceeded the BMS over-voltage protection threshold during charging.

Recommended fixDisconnect the charging source, verify charge-voltage settings, and allow the pack voltage to fall before re-enabling output.

FAULT: LED1=ON, LED2=OFF, LED3=OFF, LED4=ON (Green OFF, Red ON)Fault

Cell Temperature High.

Fault

Cell pack over-temperature protection has tripped.

CauseCells heated above the safe operating temperature (charging range 0-55 degC, discharging range -20-60 degC per spec).

Recommended fixStop charging/discharging, let the pack cool, and improve ventilation. if the fault persists at normal ambient, contact the supplier.

FAULT: LED1=ON, LED2=OFF, LED3=ON, LED4=OFF (Green OFF, Red ON)Fault

Charging Current High.

Fault

Charging over-current protection has tripped.

CauseCharge 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.

Recommended fixReduce 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.

FAULT: LED1=ON, LED2=ON, LED3=OFF, LED4=OFF (Green OFF, Red ON)Fault

Cell Voltage High.

Fault

One or more individual cells have exceeded the upper cell-voltage protection limit.

CauseCell imbalance during charging, or a charger setting that allows individual cells to drift above their safe ceiling.

Recommended fixStop charging, allow the BMS to balance, and review charger settings. if the condition persists the pack may need service.

FAULT: LED1=ON, LED2=ON, LED3=ON, LED4=OFF (Green OFF, Red ON)Fault

BMS Temperature High.

Fault

BMS / electronics over-temperature protection has tripped.

CauseInsufficient ventilation around the unit, ambient temperature too high, or sustained high charge/discharge current.

Recommended fixStop 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.

Warning codes (2)unit keeps running · needs attention

LED1=OFF, LED2=ON, LED3=OFF, LED4=OFFWarning

Battery Voltage Low.

Warning

Pack-level battery voltage is below the lower threshold (under-voltage / low-pack warning).

CauseExcessive discharge or extended period without charging; pack approaching the cut-off voltage (24 V / 48 V).

Recommended fixCharge 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.

LED1=ON, LED2=OFF, LED3=OFF, LED4=OFFWarning

Battery Voltage High.

Warning

Pack-level battery voltage is above the upper threshold (over-voltage warning at the pack level).

CauseCharger 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).

Recommended fixStop 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.

Common questions about LPBF24200-M error codes

What is the difference between a fault and a warning on the LPBF24200-M?
A fault puts the unit into protection and stops normal operation — this page lists 11 of them for the LPBF24200-M. A warning leaves the unit running; there are 2 warning codes here. Resolve the cause of a fault before restarting; warnings can usually be cleared while the unit runs.
Which model numbers does this page cover?
The LPBF24200-M shares its firmware and fault table with 4 other model numbers: LPBF48150-M, LPBF48150-P, LPBF48200-M, LPBF48200-P. If your unit is any of these, every code on this page applies to it.
Where do these codes come from?
Every entry was transcribed from Felicitysolar LPBF24200-M LiFePO4 Battery System for Households User Guide.pdf — Felicity's official documentation. Each row cites its source manual (and page where printed), so you can verify the wording before acting on it.
