What to do if my MPP Solar Hybrid LV 6KW Inverter buzzer beeps and the red LED is on?

  Willie PriceAug 6, 2025
  A continuous beep and red LED on your MPP Solar Inverter indicates several potential issues: * **Overload error:** Reduce the load by switching off some equipment. * **Output short circuit:** Check the wiring and remove any abnormal loads. * **High temperature:** Ensure the unit's airflow isn't blocked and the ambient temperature isn't too high. * **Battery voltage too high:** Check if the battery specifications and quantity meet the requirements. * **Fan fault:** Replace the fan. * **Output abnormal:** Reduce the connected load. If the battery is connected well, or if these steps don't resolve the issue, or for issues like overcharged battery, internal components failure, or surge, it's recommended to return the unit to a repair center.

Why is my MPP Solar Hybrid LV 6KW working in battery mode when mains are available?
- S
  Steven HarrisonAug 11, 2025
  If your MPP Solar Inverter is operating on battery despite mains being available, there could be several reasons: * The input protector may be tripped. Check if the AC breaker is tripped and the AC wiring is properly connected. * The AC power quality might be insufficient due to shore or generator issues. Check if the AC wires are too thin or long, and if a generator is used, ensure it's functioning correctly and the input voltage range setting is correct. * Change output source priority to Utility first.
