I am waiting for a PV system with 3 PW install in March. I have this question to the folks here. My PW’s are to be mounted on the outside of our kitchen wall. (Mounted on to the home siding). Is the PW humming noise a big issue?. I have seen some videos out there, and they do seem annoying. I have a HPWH in my garage, and the hum from that can be annoying. Am yet to get over it after 6 months. I have now asked for a design change, want to have the PW’s away from the house, mount it on a masonry wall by the fence. This also means trenching for the cables. I am OK with that, if at all that is possible, waiting for the design team to get back. Has anyone done this? Do people have issues with the humming? Or am I an outlier?
