HE-GF-FLA-48500 Manual_20250327_EN.pdfC01Battery overvoltage.Fault
Pack-level over-voltage fault displayed on the LCD BMS fault code / flag screen (section 4.3-4.4); fault icon is constant.
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).
Restart the unit; if the error persists, contact the repair center. Verify the charger / inverter Max. Charging Voltage and Floating Charging Voltage are set to 57.6 V and pack voltage stays within the 48-57.6 V operating range.
