BP3000W inverter on after the fault light flashes buzzer sound
Model
BP series pure sine wave inverter 3000W 12VDC 110VAC
Description
After power on, the fault light flashedand buzzer sounded, and it could not work normally.
Analysis of the possibility of the cause
1. Check the internal circuit to confirm that the rear stage is damaged, the rear driver board and a rear MOSfet are damaged.
2. One of the temperature control switches is in a short-circuit state and is damaged.
Solutions and steps
Replace one rear MOSfet, one rear driver board, and one temperature control switch.
