My wife is careful about EMF generated from devices near where we (and our kids) sleep. I’m researching a Multiplus-II inverter/charger, but need to find out how much EMF it might generate. It would be installed something like 2 meters from where we sleep. I am familiar with measuring EMF from a unit I already have in hand, but is there a way to find out how much this unit emits before I purchase it?
Then forget the multiplus - not for EMF reasons (dunno that) - but it is loud. Constant grumbles and when it’s under load, sounds like a pod racer from starwars
We have two stories between, but a open door policy, and when laying in the bed, I can tell when it’s charging batteries without looking in the app.
Thank you! My current Phoenix 12/30 charger is loud enough. I’ll look more at the IP43 charger that has a big heat sink and no fan and so would presumably be silent. I’ll have to either forego an inverter or find a quiet one. I realize the benefit I would lose of having a unit with inverter and charger in one, but I can’t handle a loud unit.
I think the fan on the multiplus can be disabled, leading to a reduced power-limit.
But the main noise is not from the fan, it’s the transformer which does “transformer-magnetic-induction-noise” (due to magnetostriction)
The certification is EN 55014-1 and similar. (BS EN 55014)
Most of the victron inverters have certificates and declarations of conformity for them.
The multi 2 is noisier fan wise.
But the older MP units are not noisy in my experience anyway. Except for a hum under certain circumstances.
