No problem. Pete. I just see this one repeated often, until it takes on a life
of its own.
Even above 30 MHz, a “legal” emission could be as much as S9 to a nearby
amateurs.

My mistake, Ed. I'd forgotten the "above 30 MHz" limitation on radiated
emissions.

On what basis do you believe that the SE equipment is in violation of the
emissions limits, Pete? The FCC rules set limits on radiated emissions above 30
MHz and on emissions conducted onto the AC mains below 30 MHz. There is no
emissions limits on radiated or conducted emissions below 30 MHz on any wiring
except the 120/240 volt AC mains.

I'm just curious - have you contacted the FCC., or has the ARRL done so?
This seems like a clear case of SolarEdge violating emission limits,
which they are supposed to care about.
