I have worked with Paul as well, he is good folk, and will assist...
Don't wait for RFI to find you, approach your ARRL Directors now...
Bring up RFI, and ask for reports as to what is happening RFI wise at
the ARRL.

I've had good luck contacting Paul W1VLF at the ARRL, I think he is the
new (relatively) RFI guy. Paul started the case with Solar Edge, and I
was later contacted by TJ, a senior field engineer with Solar Edge. Its
my understanding TJ, and a couple of installers, visit installation like
my neighbors to retrofit them with updated components. Now, a couple of
flies in the ointment, it hasn't been fixed....yet....parts were
supposed to be ordered in mid August, with a 10 week delivery time. That
should have been early November but he was involved with a service
emergency in CA, due to the wildfires. Also, Solar Edge is the vendor,
not the retailer, so they (Green Solar Tech) need to get
involved.....now, the final fly, and one that concerns me the most is I
sent TJ a copy of the QST article from April 2016, by Tony K1KP, that
details the fix for Solar Edge systems, and the response I received was
"Yes, I'm familiar with the article, and it is wrong".....so.....I'm
still cautiously optimistic that this will be resolved, but I'm
concerned the method they will be using.....so contact Paul at the ARRL
(copy your director as well)...Paul is very responsive and has the
contacts with Solar Edge to get the process started, and he has been up
front during this whole process......Merry Christmas to all.....

Subject: Re: [RFI] Tesla's Response to Solar Panel RFI
Our "class action" vehicle, as was already pointed out, is the ARRL. As
part of their charter to protect our spectrum and represent their members
in all aspects of the hobby, they need to step up to the plate and take
charge of the Solar RFI problem. They, in turn, need to (1) contact
offending companies, and (2) pressure the FCC to become aware of the
entire
noise level problem and start enforcing their rules.

Hi Jim,
Respectfully, in every case here but one, (and I have been involved in
maybe 10 to 15 in the past three years), the RFI from grow ops were
unheard on the AM band with a local station tuned in, and while in front
of the offending grow op.
I am sure that in some cases it is hearable on an AM channel, but so far
here, (and I have expressly, checked at each location), I have had very
little luck with this. It is one of the first things I check for, so I
can involve the CE of the AM station being affected...
