Also applies to:FLA48200
What it means
Battery overvoltage
Cause: The total battery pack voltage rose above its rated protection value during charging, so the BMS stopped charging. The protection releases once the pack voltage returns to the rated range.
How to fix it
- 1Restart the unit.
- 2If the error persists, contact the repair center.

What it means
Battery overvoltage — BMS reports total battery pack voltage above the upper protection threshold.
Cause: The total battery pack voltage rose above its rated protection value during charging, so the BMS stopped charging. The protection releases once the pack voltage returns to the rated range.
How to fix it
- 1Restart the unit.

What it means
Battery overvoltage — Battery overvoltage protection triggered (pack-level voltage exceeded threshold).
Cause: Battery pack voltage above operating limit (operating range 44.8-57.6V; max charging voltage 57.6V).
How to fix it
- 1Restart the unit.
- 2If the error persists, contact the repair center.

What it means
Battery overvoltage — Pack-level over-voltage fault displayed on the LCD BMS fault code / flag screen (section 4.3-4.4); fault icon is constant.
Cause: Pack voltage exceeded the BMS over-voltage threshold during charging - typically because the charger's Max. Charging Voltage is set above the recommended 57.6 V (section 2.4 Recommended Settings).
How to fix it
- 1Restart the unit; if the error persists, contact the repair center.
- 2Verify the charger / inverter Max.
- 3Charging Voltage and Floating Charging Voltage are set to 57.6 V and pack voltage stays within the 48-57.6 V operating range.
