    After an on-site visit and testing by an FCC Enforcement Agent of the ~S9 interference cause to my station by a Solar City solar array located 2 houses away, the FCC issued Solar City a Notice of Violation.

    It appears that at least one of the primary interference generating components is a load balancing device called an "optimizer" which is attached to back of each solar panel. Testing by the FCC Agent showed that the interference does not stop until the optimizer is detached from the solar panel. Attempts by Solar City to add filters were unsuccessful and only resulted in a few DB of change.

    The optimizer (as well as the the rest of the system) is manufactured by Solar Edge. I was told by Solar City when I inquired about them installing a different type of system that this is the only kind of system that Solar City installs. Given this it's not hard to envision that many Solar City installations are causing this type of interference. Fortunately the FCC is concerned about this issue and is actively working to resolve it.

    Got an interference issue? Do your homework and file an FCC complaint. It's what starts the process.

    Thanks for the update. Very interesting.

    Can you remind us what contact information you used to contact FCC to get enforcement? That would be good information to keep handy in case something like this happens to other hams.

    OK, they got a Notice of Violation. Does that have any teeth? When are you going to see relief?

    That's fantastic! This news is very encouraging for more vigorous RFI enforcement by the FCC. There are many administrative steps and we will see what the results eventually are, but it is a good step.

    Nice job on your part, keeping notes, etc., to a standard that the FCC will work from them!

    After reading the description on their site, I don't see the value in the device, it seems like a BS device that sounds technically valuable as to trick the buyer so the seller can jack the price up.

    Fortunately Solar City has no interest in doing business in my state. Something about the panels being covered by snow and ice half the year and a very low rate of return keeps them out of the market. Screen Shot 03-17-17 at 07.32 AM.PNG

    Given the diligent homework that he has done, I suspect that the OP knows that he will have to follow up with this. In this type of situation, you can never just file a complaint of expect things to be fixed. Eternal vigilance.

    ALWAYS be suspicious of those who 'talk with their hands'.

    If you want to hear the SECRET MESSAGE...run both videos at the same time...
