All: The the inverter on my neighbors solar panel installation was recently replaced to reduce the RFI caused by the system. The swap only made a slight change in the interference. This left the sola
Inverters are inherently noisy. So you replace a noisy one with another noisy one. You cover the panels so the inverters have nothing to invert. That doesn't mean the solar panels are the culprit. Pl

If this is a Solar Edge system, are they using "optimizers"? They are DC to DC, but still create switching noise. I'd look there first. Unless your neighbor switched to a known quiet inverter it was

Tony Was this experiment conducted with the per-panel optimizers connected to the panels? This is a critical question. It appears the conclusion of the experiment is that the panels themselves and by
I think that it is highly unlikely that the panels themselves are creating noise. Paul Cianciolo, W1VLF, has a Solar Edge system at his house. He had found the usual wiring, grounding and optimizer i
I agree with Ed and Tony Brock-Fisher's observations. More than a year ago, I gave Solar Edge's guy, who lives in the SF Bay area, a tutorial on the topic, and told him that the solution was design e
Although it seems intuitive that escalating these problems to the FCC or other actions with legal implications will speed things up, just the opposite it true. Right now, we have good contact with So
Thanks Ed. I would like that. Yes, I think that properly addressing grounding at the mains interface is at least as critical as filtering. 73, Jim _______________________________________________ RFI
There was a good conversation about this a year or so ago on this reflector. As I recall, the system generated interference with the panels disconnected. Seems like certain panel manufacturers were s
It is highly unlikely the panels themselves generate RFI without the optimizers I agree with you Tony. When we informed SolarEdge about the noise disappearing when we covered the panels, they came to

The obvious test would be to disconnect the optimizers from one or more panels, expose them to sunlight, but cover all the rest. This configuration should be quiet. -Tony It is highly unlikely the pa
Someone at SolarEdge doesnt seem to know that cells are diodes. Cortland -Tony It is highly unlikely the panels themselves generate RFI without the optimizers I agree with you Tony. When we informed
This could be misleading. In the unlikely event that the panels themselves are generating noise, disconnecting them from the optimizers would remove them from a large length of common-mode radiator.
I also have trouble accepting the panel noise theory SolarEdge claims. If that were true, why is it that some brands of inverters never cause RFI, yet the same solar panels are used on all solar powe
I also have trouble accepting the panel noise theory SolarEdge claims. Simple enough solution... They spew their BS, in the hope one swallows it whole and wanders away. Response? "Prove it". That usu
Regarding SolarEdge or any other company selling and installing Solar powered equipment. These cases are not the first ones. SolarEdge has fixed others so they are RFI quiet. You can't tell me that S
I am not sure that I would say that "Solar Edge" believes the panels are noisy. One engineer or installation technician may have said that, but I've never heard that from our high-level engineering c
