  If the buzzer beeps continuously and the red LED is on, it could be due to several reasons: * A short circuit in the output: Check the wiring and remove any abnormal load. * An overload error: Reduce the connected load by turning off some equipment. * Output voltage is too high or too low: Return the unit to a repair center. * Fan fault: Replace the fan.

Why does my APT Inverter work in battery mode when mains exist?

  Jeffery RoyAug 20, 2025
  The APT Inverter might be working in battery mode even when mains are available due to: * A tripped input protector: Check if the AC breaker is tripped and ensure the AC wiring is properly connected. * Insufficient AC power quality: Inspect the AC wires for being too thin or long. Also, if using a generator, verify it's functioning correctly and that the input voltage range setting (Narrow/Wide) is appropriate.
