Subject: Re: [RFI] Update: Tesla's Response to Solar Panel RFI
Actually, the FCC really hasn't given up on HF. What I have said is that
there are no radiated emissions limits for unintentional emitters below 30 MHz.
(There are conducted limits onto the AC mains.) But the FCC has sent out many
dozens of advisory letters to operators of various devices on the basis of
harmful interference. Now, they will set a higher threshold for harmful
interference than we like, but the can and do take some (limited) action.
ARRL has worked hard to keep this alive in the FCC, and so far, it has held.
The solar panels are unique. Their conducted emissions limits apply ONLY the
ac mains, not other wires, so many of these systems that can and do cause
interference do actually meet the laws about radiated and conducted limits.
Solar Edge may be a bit slow, but they are responding and ARRL maintains
regular contact with them. We have a few unresolved cases and we are planning
a field trip to go take a look at them in person, hopefully with Solar Edge
and Tesla also present.
