I have an SMA 2500U in my bedroom outside wall and Tigo Maximizers on
the modules and have noise on AM radio in the bedroom in the daytime.

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.

Subject: Re: [RE-wrenches] AM noise on batteryless inverters
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 avaiable from DigiKey
