My neighbor across the street had a 21 panel Solar Edge array installed in May 2019, 6.5 kw I believe. I had the 18kc noise spikes, and the 200kc spaced optimizer noise. After working with Paul at th
THANK YOU PAUL/ED/ARRL!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Each time this happens Solar Edge learns a little, and it makes it faster, and simpler for the next Amateur! 73, and thanks, Dave (NK7Z)
One of the first things I did was to join ARRL as a LIFE member. As for the solar installs..... I've now seen tons of cases like this where the noisy installation was "fixed" by the installer.... Ju
James: Solar Edge used the same suppression techniques on my neighbors installation and it only reduced the noise from S-9 +15 db to S-9 which is still very high. I suspect that the suppression would
If SolarEdge applies their fix and the noise is still too high, it is possible they missed one panel. That happened with one of my neighbors about two years ago. They finally got it right on the four
We have come a long way, but still have a ways to go. Fortunately, we are dealing with a company that is holding space for all of this and willing to work towards better and better solutions. The ini
This sounds like something the ARRL and W1VLF should be paid for!!! In my small EMC/RFI consulting business, I sure wouldn't be doing this for free!!!!!!! Some limited up-front consulting is in order
hes directly across the street from me, all the lots in the subdivision are 80x180 ft, his array is on his rear roof, and my antennas are in my back yard, so 260-285 ft, something like that.... James
Our problem in such cases is still the Commission's reluctance to enforce the rules against causing harmful interference regardless of the maximum permitted level of emissions. I note that Class A ba
James: Your antenna is about 150 feet further away compared to the distance between my neighbors solar panels and my antenna. Its about twice the distance so in theory the noise would be 1/4th as str
That's oversimplified for relatively large sources and short distances. Inverse law (3dB/doubling) may be more applicable. 73, Jim K9YC _______________________________________________ RFI mailing lis

It is far from that simple, Cortland. "Enforcement" is a very broad term that can range from the advisory letters routinely mailed by the FCC in response to complaints about harmful interference to t
Its a little more complicated than that, Dave. ARRL is funded to do this sort of thing and members expect that for their membership dues, ARRL will do what it takes to help ensure as much of a noise-
