I haven't found any other comments about this here so I am thinking I may have a defective unit or nobody has theirs mounted where the can hear it. I installed the new MP 2x120v and when charging the noise coming from the inverter is excessive (over 50dB measured 6" above the unit). It is significantly more than when inverting. I do have it mounted lying on its back but have the same noise when positioned vertically. The noise is immediate once you "Enable Charger" and stops immediately when it is disable. We can call it a hum if we like but it is way too loud to be considered normal or as designed in my opinion. I never even heard the unit when I used the old MP 12/3000 mounted in the same place. Can those with this new unit comment on how the noise compares while charging vs inverting? Is it significantly greater or similar? Trying to ensure Victron will agree it's not right before I go through the warranty process.
