[RE-wrenches] AM noise on batteryless inverters

[jay peltz]

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
