[RFI] Another Solar Panel RFI Victim

[James Gordon Beattie Jr]

Ed,
I think you're raising the point that the current standards for radiated and conducted emissions are seemingly inadequate and need to be revisited.

Naturally, equipment vendors and manufacturers are going to "push back", but these emissions are blanketing the spectrum from DC to light (metaphorically).  We need quantified measurements and their effects documented in order to start making the case for improved standards in both FCC Part 15 and Part 18. It's not just an Amateur Radio issue.  It impacts AM and FM radio, OTA television, public safety and aviation, cellular and potentially other services.  The only way to proceed is to collect measurements and the impact on these and other services.

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.
