Inverter working light on but the buzzer emits one short and one long beep

Model

BP Series Pure Sine Wave Inverter 24VDC 220VAC 6000W

Description

1. After the inverter is turned on, the working light is on, the fault light is off, and the buzzer emits one short and one long beep.

2. Input voltage is normal, no output voltage, no load is connected.

Analysis of the possibility of the cause

1. Judging by the buzzer, the machine is in an overcurrent and overload state.

2. Because the load is not connected, it is judged that the U8 LM258 chip on the rear motherboard is damaged, and a false alarm occurs.

Solutions and steps

Return to the factory for repair or replace the chip by yourself.
