Why is my Flin Energy 3KVA working in battery mode when mains exist?

  charlessawyerAug 11, 2025
  If your Flin Energy Inverter continues to operate in battery mode even when mains power is available, it could be due to: * A tripped input protector. Check if the AC breaker has tripped and ensure the AC wiring is properly connected. * Insufficient AC power quality, possibly from a shore or generator source. Verify that the AC wires aren't too thin or excessively long. Also, make sure that the generator (if used) is functioning correctly and the input voltage range setting is correct for your UPS Appliance.

What to do if my Flin Energy 3KVA has no response after power on?
- M
  Michael CainAug 17, 2025
  If your Flin Energy Inverter doesn't respond after you power it on, the possible causes are: * The battery voltage is too low (below 1.4V/Cell). Check the battery and wiring connections. * The battery polarity is reversed. Re-charge battery. In other cases, replace the battery.

Why does my Flin Energy 3KVA shut down during startup?
- K
  Kristine CastroAug 23, 2025
  If your Flin Energy Inverter shuts down automatically during the startup process, it may be due to: * Low battery voltage (below 1.91V/Cell). Try re-charging the battery. In other cases, replace the battery.

What to do if my Flin Energy 3KVA Inverter buzzer beeps and the red LED is on?
- J
  Jake HayesNov 5, 2025
  If the buzzer on your Flin Energy Inverter is beeping continuously and the red LED is illuminated, it could indicate several issues: * The inverter is overloaded (over 110%). Try reducing the load by switching off some equipment. * There is a short circuit in the output. Check the wiring and remove any abnormal loads. * The internal temperature of the converter component is too high (over 120°C, for 1-3KVA models). Ensure the unit's airflow isn't blocked and the ambient temperature isn't too high. * The battery voltage is too high. Ensure the battery specifications and quantity meet the requirements. * There is an output abnormality (inverter voltage below 190Vac or above 260Vac). Reduce the connected load. Other potential causes include a fan fault (replace the fan), over curr...
