The Felicity LPBF48200-H is a Battery unit covered by a shared firmware family that includes 2 variants. The error codes listed below apply to every variant in this family — LPBF48200-H, LPBF48100-H. If your unit's exact model number isn't shown in the title but is listed in the "also covers" tags, this is the correct reference page.
Each row below shows an error code, its severity, and a brief description. Click any row to expand the full cause and the recommended fix. The severity dot tells you whether the unit will keep operating (warning), derate (fault), or trip offline (critical). For codes that require an authorized service partner, the recommended-fix block says so explicitly.
Battery pack overall voltage above protection threshold (BMS protection).
Total battery voltage has exceeded the BMS upper voltage limit.
Restart the unit; if the error persists, contact the repair center.

Restart the unit; if the error persists, contact the repair center.
Manual-LPBF48200-H.pdf · page 10An individual cell voltage has exceeded the protection limit.
One cell voltage above safe upper threshold (cell imbalance or overcharge).
Restart the unit; if the error persists, contact the repair center.
Manual-LPBF48200-H.pdf · page 10An individual cell voltage has dropped below the protection limit.

Restart the unit; if the error persists, contact the repair center.
Manual-LPBF48200-H.pdf · page 10Charging current has exceeded the BMS protection limit.
Charging current above the maximum charge current rating (>120A on LPBF48200-H).
Restart the unit; if the error persists, contact the repair center.
Manual-LPBF48200-H.pdf · page 10Discharge current has exceeded the BMS protection limit.
Discharge current above the maximum discharge rating (>120A on LPBF48200-H).
Restart the unit; if the error persists, contact the repair center.
Manual-LPBF48200-H.pdf · page 10MOSFET (power switch) temperature is above the operating limit.
Internal temperature is over the limitation; ambient temperature may be too high.
1. The inner temperature is over the limitation. 2. Check whether the ambient temperature is too high.
Manual-LPBF48200-H.pdf · page 10MOSFET (power switch) temperature is below the operating limit.
Internal temperature is lower than the limit range; ambient temperature may be too low.
1. The internal temperature is lower than the limit range. 2. Check whether the ambient temperature is too low.
Manual-LPBF48200-H.pdf · page 10An individual cell temperature has exceeded the operating limit.
Cell temperature above safe upper threshold (likely high ambient temperature or excessive current).
Restart the unit; if the error persists, contact the repair center.
Manual-LPBF48200-H.pdf · page 10An individual cell temperature is below the operating limit.
Cell temperature below safe lower threshold (likely cold ambient, charging blocked below 0 deg C).
Restart the unit; if the error persists, contact the repair center.
Manual-LPBF48200-H.pdf · page 10BMS internal current measurement circuit fault.
Current sensor / sampling circuit malfunction (internal hardware fault).
Restart the unit; if the error persists, contact the repair center.
Manual-LPBF48200-H.pdf · page 10Output impedance is outside expected range.
Loose terminal connection, internal MOS/wiring fault, or external short/open condition affecting impedance.
Restart the unit; if the error persists, contact the repair center.
Manual-LPBF48200-H.pdf · page 10Battery pack could not satisfy parallel-operation conditions (e.g. voltage difference between local and other packs >3V, or wiring issue).
Single unit configured as parallel slave, mis-wired parallel connection, or voltage mismatch (>3V) between paralleled packs.
1. Please check if single unit is installed to parallel system. 2. if this error happens during parallel installation, please check wires connection. if they are connected correctly, please finish parallel installation first, and then restart the unit. 3. if the problem remains, please contact your installer.
Manual-LPBF48200-H.pdf · page 10Write down the exact code shown on the display, what the unit was doing when it appeared (charging, discharging, idle, grid-tied), and any LEDs or audible alarms. The same code can have different fixes depending on context.
Find the code in the list below and read the cause + recommended fix. Most warning-level codes can be cleared by following the listed action — usually reducing load, checking wiring, or restarting the unit.
Each code shows the source manual filename and page number. Open that exact page in the official manual to verify model-specific notes (firmware version, parallel-config notes, regional variants) before acting.
If a fix requires opening the enclosure or accessing terminals, disconnect AC input, DC PV, and battery in that order. Wait at least 60 seconds for capacitors to discharge before touching any conductors.
Critical codes (short-circuit, IGBT failure, BMS hardware error) should not be cleared by end users. Note the code, model number, and source manual page, then contact an authorized service partner.
