  If your Crown Micro Inverter buzzer beeps continuously and the red LED is on, it could be due to several reasons. It might be an output short circuit, so check the wiring and remove any abnormal load. Overload error may occur, so try reducing the connected load by switching off some equipment. The battery may be too low, so charge or replace it. Other potential causes include output voltage being too high, main relay stick, fan fault, internal temperature being too high (check air flow and ambient temperature), over-charged battery, or the battery voltage being too high (check battery specs and quantity). For issues like high output voltage, main relay stick, or over-charged battery, it is recommended to return the unit to a repair center. If it's a fan fault, consider replacing the fan.

Why is my Crown Micro Inverter working in battery mode when mains exist?

  If your Crown Micro Inverter is working in battery mode even when mains are available, the input protector might be tripped. Check if the AC breaker is tripped and ensure the AC wiring is properly connected. Another possible cause is insufficient quality of AC power, especially from shore or generator sources. Verify that the AC wires are not too thin or long, and if using a generator, ensure it is working correctly and that the input voltage range setting is correct (Narrow Wide). Alternatively, change the output source priority to Utility first.

Why is the backup time of my Crown Micro Inverter so short?

  If your Crown Micro Inverter's backup time is shortened when the power fails, it could be due to a low battery voltage. Charge the unit for at least 8 hours. If the battery capacity is still not full after charging, check the battery's date code. If the batteries are too old, replace them.

What to do if there is no LED display on my Crown Micro Inverter?

  If there is no LED display on the front panel of your Crown Micro Inverter when the utility power is normal, the battery may not be connected well. Check the external battery cable and terminal to ensure all battery connections to the unit are correct. It could also be due to a battery defect, in which case you should replace the batteries.
