What to do if the Mecer Inverter buzzer beeps continuously and the red LED is on?

A continuous beep and a red LED indicate several potential issues. First, check the wiring and remove any abnormal load, as the output may be short-circuited. Second, if the inverter is overloaded (over 110%), reduce the connected load by switching off some equipment. Other potential causes include output voltage being too high or the battery being over-charged, in which case you should return the unit to the repair center. Also, a fan fault may cause this issue, so the fan should be replaced. Further, check if the air flow of the unit is blocked or the ambient temperature is too high, as the internal temperature of the inverter component may be over 100°C. Finally, ensure the battery voltage isn't too high and that the battery specifications and quantity meet requirements.
