What to do if my Luminous 3KVA Inverter is beeping continuously and the red LED is on?
- D
  Diane GuzmanAug 8, 2025
  A continuous beep and a red LED on your Luminous Inverter usually indicates a problem. This could be due to several reasons: * The inverter might be overloaded (more than 110% load). Try reducing the load by switching off some equipment. * There may be a short circuit in the output. Check the wiring and remove any unusual loads. * The internal converter component's temperature might be too high (over 120°C). Ensure the unit's airflow isn't blocked and the ambient temperature isn't too high. * The battery voltage may be too high. Verify that the battery specifications and quantity meet the requirements. If none of these steps resolve the issue, it may be necessary to return the inverter to a repair center.

Why does my Luminous Inverter work in battery mode even when mains exist?
- J
  Jonathan NelsonAug 14, 2025
  If your Luminous Inverter continues to operate on battery power despite the availability of mains power, there are a few potential causes: * The input protector might be tripped. Check if the AC breaker has tripped and ensure the AC wiring is properly connected. * The quality of the AC power (from shore or generator) may be insufficient. Check if the AC wires are too thin or too long. * The solar power may be set as the priority output source. Change the output source priority to 'Utility first'.

What to do if there is no response after powering on my Luminous 3KVA Inverter?
- R
  Rachel BennettAug 27, 2025
  If your Luminous Inverter doesn't respond after you power it on, consider these potential causes: * The battery voltage might be extremely low (less than 1.4V/Cell). Check the connections of the batteries and wiring to make sure they are well connected. * The battery polarity may be connected in reverse. Recharge the battery. * The battery might need replacement.
