The 2000W inverter buzzer buzzes at intervals but the fault light is off
Model
BP Series Pure Sine Wave Inverter 24VDC 220VAC 2000W
Description
1. After the inverter is turned on, the working light is on, the fault light is off, there is no output voltage, and the buzzer buzzes at intervals.
2. Detect that the input voltage is normal, and the output is not connected to the load.
Analysis of the possibility of the cause
1. Open the cover and check, it is found that the work light of the rear board flashes after power on, unplug the temperature control line, restart the machine, and it is normal.
2. It is judged that the temperature control resistor has a short-circuit, which leads to over-temperature protection after the machine is turned on.

Solutions and steps
Replace the temperature control resistor that shown as the black wire. This one is connected to the radiator to detect the internal temperature.
