I have a problem with loud humming noiseon Multiplus II.
the multiplus is hearable in the house throu 3 walls easily.
and because victron is often used in caravans i cant belive that tis is normal :).
so my question is what i i make better to reduce this noise?
i found out that the noise is sometimes oscillatin, that means it is getting lower (down to zero and comes back up to full noise) therwhile it is the normal inverting power (200-500w)
so maybe the following reason is responsible??
we have a bad power factor (it is a new house with lots of Ledˋs Transformers and more.
(We have in standby a power factor of 0.1-0.5) “dont know if this is normal for new houses„?
hope for your help.
