Very Loud- Multiplus II 3000 2x120 50 amp

Just installed unit, Wow! Super loud. Don’t know what to do, can’t get help. When connected to outside AC (pedestal) and charging. Hum and vibrations cause reverberations throughout my RV shut off input AC and unit is quiet. In idle inverter mode super quiet. It’s so loud can’t sleep in peace.

Excellent. Use victron connect and update that way.
