  Patricia WalkerAug 12, 2025
  If your Voltronic Power Inverter is running on battery despite mains being available, consider these potential causes: * A tripped input protector. Check if the AC breaker has tripped and ensure the AC wiring is properly connected. * Insufficient AC power quality from the shore or generator. Inspect the AC wires for being too thin or long. If using a generator, verify it's working correctly and that the input voltage range setting is correct (UPS Appliance). * You may need to change the output source priority to Utility first.

What to do if my Voltronic Power Inverter buzzer beeps and the red LED is on?
- K
  Kurt HodgesNov 6, 2025
  A continuous beep and a red LED on your Voltronic Power Inverter usually indicates an error. Here's what might be happening and how to address it: * **Overload:** Reduce the load by turning off some equipment. If using PV modules, reducing the number in series may help. * **Short Circuit:** Check the wiring and remove any abnormal loads. * **Over Temperature:** Make sure that the unit's airflow isn't blocked and that the ambient temperature isn't too high. * **High Battery Voltage:** Check that the specification and quantity of batteries meet requirements. * **Fan Fault:** Replace the fan. * **Abnormal Output Voltage:** Reduce the connected load. * **PV Input Voltage Exceeded:** Reduce the number of PV modules in series. * **Over current or surge:** Restart the unit, if th...
