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.

<blockquote type="cite">Hi Darryl,
<br>
<br>
Personally I've tried this and had no luck with offgrid
<br>
<br>
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
<br>
SMA or Fronius.
<br>
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.
<br>
<br>
So I'm trying to find if anyone else has had anything similar?
<br>
<br>
Thanks,
<br>
