I have an Phoenix 12/1200 in my motorhome, and it makes a buzzing sound when it`s turned on. And when I put a load on it, when charging our e-bikes with 160w AC, the buzzing gets really high.
I did return it to the seller in Germany, But they said it is like that with Victron inverters… so they sent it back to me and they also send me some rubber ”feets” to put between the inverter and the wall so The sound dont get amplified from the wall
Is this normal?
is there anyone else with similar problem?
