I have recently had solar panels installed on the roof of our attic. They hung the inverter on a hollow plasterboard wall as this was the most easily accessible.
However, every time the solar inverter turns on, there is a rather annoying series of clicks of an internal relay, and the sound is massively amplified due to the hollow wall onto which it is mounted. I now have two options,
- Hang the inverter on an outer (stone) wall nearby. Since I don't want to void my warranty right away (or worse, create a fire risk with diy DC cabling), this probably involves getting the contractor over, and the inverter would have to hang over the stairs making it quite inaccessible.
- Somehow reduce the emission of sound from the drywall.
What options do I have for the second option? I suppose I can put some damping material between the inverter and the wall. My instinct would be to drill the screw through felt patches, but maybe there are better options? Also, the sound might still transfer through the screws into the wall. Perhaps there exist purpose-built wall plug / anchors with sound or vibration isolation?
