FAULT: LED1=ON, LED2=OFF, LED3=OFF, LED4=OFF (Green OFF, Red ON)Battery Voltage High.Fault
Description

Pack-level over-voltage protection has tripped; output is disabled. Listed in the FAULT row of the LED table on page 7 as 'BATTERY VOLTAGE HIGH'.

Cause

Pack voltage exceeded the BMS over-voltage threshold during charging — e.g. charger output above the recommended Max. Charging Voltage of 57.6 V (section 2.4).

Recommended fix

Stop charging, verify the charger / inverter Max. Charging Voltage and Floating Charging Voltage are set to 57.6 V per section 2.4, and allow the pack voltage to fall back into the 48-57.6 V range before re-enabling output.
