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.

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. / _______________________________________________
