Why is my APT Inverter working in battery mode when mains are available?
- D
  dgoodwinAug 11, 2025
  If your APT Inverter continues to operate in battery mode even when mains power is available, it could be due to a few reasons: * The input protector might be tripped. Check if the AC breaker is tripped and the AC wiring is properly connected. * The AC power quality might be insufficient, especially from shore power or a generator. Check if the AC wires are too thin or too long. If using a generator, ensure it's working correctly and that the input voltage range setting is correct for a UPS appliance. * The output source priority may be set incorrectly. Change the output source priority to Utility first.

  If your APT Inverter doesn't respond after you power it on, the issue might be: * The battery voltage is too low. Check if the batteries and wiring are well connected, and then try recharging or replacing the battery. * The battery polarity is reversed. Double-check the battery connections and wiring, then try recharging or replacing the battery.

What to do if the APT VEYRON IV 3.2KW Inverter buzzer beeps and the red LED is on?
- N
  Nancy BoydNov 4, 2025
  If the APT Inverter's buzzer beeps continuously and the red LED is on, it could be due to several reasons: * The inverter might be overloaded (over 110%). Try reducing the load by switching off some equipment. * There could be a short circuit in the output. Check the wiring and remove any abnormal load. * The internal converter component might be overheating (over 120°C). Ensure the unit's airflow isn't blocked and the ambient temperature isn't too high. * The battery may be over-charged. In this case, return to the repair center. * The battery voltage may be too high. Check if the battery specifications and quantity meet the requirements. * There may be a fan fault. In this case, replace the fan. * The output may be abnormal (Inverter voltage below than 190Vac or is higher ...
