About AC-out-2 of my inverter and noise level changing


I have a MultiPlus-II 48/3000/32-35 victron energy inverter.
I connected the washing machine to AC-out-2 of my inverter.

During its operation, the noise from the inverter changes relative
to the standard operation of the washing machine.

When the washing machine rotates its drum at a low speed and hums - my inverter also begins to hum - almost synchronously.

This is normal?

Thanks!

I don't know if a washer load is similar to a hairdryer but have you seen this and many similar posts? https://community.victronenergy.com/questions/301424/multiplus-noise-powering-a-hairdryer.html

Thanks!

But I can't find information about "hum" noise in AC-out-2 when invertor work from grid with washing machine, not from battery...

A washing machine motor is an inductive source. The inverter has and inductor. And then there is physics in between.

The noise is normal for the inverter type you have.

Sounds normal to me as well.

There are different types of motors in machines these days, but most washers will constantly stop and change direction and speed, which affects the load on the multi.
