Hi there, I'm running a Hyundai 6kw ats generator through my multiplus 3000, I'm getting around 1600w coming through, all runs fine accept a loud vibrating noise coming from the centre of the multiplus. The question is should I be concerned by the noise, it's not a normal inverter noise more like zapping sound and also sounds like a neighbour is using a drill on the otherside of the wall?
Any help would be appreciated.
Thanks
