Why does my Flin Energy 3kVA-24V work in battery mode when mains exist?
- J
  Jasmine MartinezAug 4, 2025
  If your Flin Energy Inverter continues to operate in battery mode even when mains power is available, the following could be the reasons: * **Tripped Input Protector:** Check if the AC breaker has tripped and ensure the AC wiring is properly connected. * **Poor AC Power Quality:** The AC power from the shore or generator might be insufficient. Verify that the AC wires are not too thin or too long. If using a generator, ensure it is working correctly and that the input voltage range setting is correct. You might also consider changing the output source priority to 'Utility first'.

  Brian MasonAug 8, 2025
  If your Flin Energy Inverter doesn't respond after you power it on, it could be due to the following reasons: * **Low Battery Voltage:** The battery voltage might be too low (below 1.4V/Cell). Check the batteries and wiring to ensure they are well connected and recharge the battery. * **Reversed Battery Polarity:** The battery polarity might be connected in reverse. Replace the battery.
