Radio frequency interference with recently installed solar panels

[bob-n]

Mike and Bruce are right. Your SolarEdge is producing RF noise.

If they can change the interference by turning on and off a piece of equipment, then it isn't shielding. It is that piece of equipment spewing noise. It could be that the EMI filter on one string is worse than the EMI filter on the other string, but those filters are inside the SolarEdge box, so it strongly suggests that the SolarEdge box is your problem.

Bruce is also right that a better FM antenna and placing it far from the SolarEdge and far from the panels will help. Getting a new SolarEdge might or might not help, but I'd be tempted to demand that they do that first.

It is a bit strange that only half of your setup generates noise, could be a partially failed
component. I would start with a portable radio (AM and FM if possible) and move it around
the equipment looking for the source of the noise. Look for bad connections or a specific
part. Swapping some around might identify which is/are the noise source. Straight string
converters are the easiest to clean up, with active components off the roof.

Yes even a simple roof mount FM antenna will help, again move it away from the noise
source. Best is to use an antenna mount amplifier to get the signal well above the noise
before the transmission line. Bruce Roe

PV panels make a poor shield. RFI blocking the FM radio band is unusual.

That's my 2 cents

I recently had panels installed in 2 series on either side of my ridge line and now have rfi when trying to listen to fm radio. A SolarEdge tech remotely turned off
each series and found that one array, on the western side of my home, caused the rfi. He said the pv panels themselves are producing a “shield” blocking the fm signals.
i don’t speak this stuff very well, but im hoping I can install an fm antenna on the roof, run wire into my attic, and reamplify the radio signals there, to allow 3 radios in different rooms, to capture a clean signal.
is this a viable solution?
does anyone have experience doing this?
are there others ways of accomplishing my goal?

i have 26 LG 335 panels with SolarEdge optimizers and inverters.

as I mentioned, I’m very uneducated with all this stuff. any device w/b very appreciated.
