Along these "AC noise" lines.......
About 6-7 years ago I installed 2, SMA 2500U inverters at a friend's
(most dangerous situation, installing for a friend...like selling a friend
your used car!) place. This guy is a Ham radio operator AND the inverters
are on the wall opposite all of his gear (what was I thinking?)
Fortunately, he's still my friend...no noise can be detected on his ham
radios.

Hi Darryl,
Personally I've tried this and had no luck with offgrid
But the issue is that a very competent installer friend, whos not on the
wrenches has had issues with PV powered and AM radio noise, but not with
SMA or Fronius.
He's actually swapped inverters same location from PV to SMA and the AM
noise was gone and has had this problem enough times to no longer use them
for folks who like to listen to AM during the day.
So I'm trying to find if anyone else has had anything similar?
Thanks,
jay

I have heard that putting small ferrite donuts around the AC and DC wires
will reduce this noise. Place them inside the inverter. they are
