[Hare, Ed, W1RFI]

Now, as this specific case, I will have Steve Anderson contact them and see what we can do to get GroWatt into the fold for improved cooperation.

All:

The list of complaints regarding solar panel RFI issues continues to grow. I just received yet another message from a fellow ham who is experiencing RFI from a GroWatt 3000TL system -- see below.

Most of the complaints I heard about over the years involve systems made by Solar Edge and Generac, but it looks like we can add GroWatt to the list.

/I just installed a GroWatt 3000TL for an offgrid system. RFI is horrendous! I just tried putting a 4 inch 31 mix ferrite donut on the battery leads. I was able to get four passes through the donut. No measurable suppression. So I might have to resort to disconnect the panels when using the rig but what a sad situation. When I'm not using the station I am going to be polluting the spectrum for others. I stunned that these manufactures do not have to comply with an FCC regulations. / _______________________________________________
