Victron Multiplus 2 buzz

[jamiegreen]

Has anyone experienced a vibration/buzzing from (I think) the small coil winding within the Multiplus II? I don't recall it making this noise before, and it's very sensitive to just tapping even the outer casing of the unit slightly. And no it's not the main transformer making the nose! All working fine though.

Here's a video, might have to turn it up loud.

Check and see if this matches your situation:

Multiplus II fan vibration and retrofit kit

I have heard/read reports of fan vibration noise in Multiplus II inverters. I just found this...There appears to be a retrofit kit available for those models affected, where firmware updates don't help. Some other options herein may or may not void your warranty....
