      Mr. Reginald White MDAug 7, 2025
      A continuous beep and a red LED on your MPP Solar Inverter often indicates a critical issue. Here's what might be happening and how to address it: * **Overload error:** Reduce the load by turning off some equipment. * **Output short circuit:** Check the wiring and remove any abnormal loads. * **Internal temperature too high:** Ensure proper air flow and that the ambient temperature isn't too high. * **Battery voltage too high:** Verify the battery specifications and quantity meet the requirements.

      Randall SchwartzAug 13, 2025
      If your MPP Solar Inverter is operating on battery power despite the presence of mains, consider the following possibilities: * The input protector might 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 issues with shore power or a generator. Verify that AC wires aren't too thin or long. If using a generator, ensure it's functioning correctly and the input voltage range setting is correct. * The output source priority is not set correctly. Change the output source priority to Utility first.
