  If the APT Inverter's buzzer beeps continuously and the red LED is on, it could be due to several reasons: * Output short circuit: Check the wiring and remove any abnormal loads. * Overload error: Reduce the connected load by switching off some equipment. * Weak battery: Recharge or replace the battery. * High or low output voltage, over-charged battery, or main relay stick: Return the unit to the repair center. * Fan fault: Replace the fan. * High internal temperature: Ensure the unit's airflow isn't blocked and the ambient temperature isn't too high. * High battery voltage: Check if the battery specifications and quantity meet the requirements.

  The APT Inverter might be working in battery mode even when mains are available due to these reasons: * The input protector has tripped: Check if the AC breaker is tripped and the AC wiring is well connected. * Insufficient AC power quality: Inspect if the AC wires are too thin or long. If a generator is used, verify it's working correctly and that the input voltage range setting is correct. * Check output source priority: Change output source priority to Utility first.
