When dealing with noise on power lines, time to get my Jackery 240 out. Talk about clean can hold a portable am radio next to the thing and no buzz. Purchased the thing in 2019 for back up power during storm season hate running a gen set at night. One can never have to many of the things! Others on the market but have no idea how clean the power is they make. On the old engine form folks were talking about THD from there gen sets some starting checking grid power at there homes and reported low of 1.7 to a high of 3.9 would never guessed a high of 3.9.
