Why MaxPower Sunglow VMII 5000 Inverter works in battery mode when mains exist?
- AAmy LewisAug 15, 2025
If your MaxPower Inverter isn't working in mains mode even when mains are 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. Another cause might be the AC power quality is insufficient, especially from shore power or a generator. Verify that the AC wires aren't too thin or too long, and if using a generator, make sure it's working correctly and the input voltage range setting is correct. You can also try changing the output source priority to Utility first.
