All: The reports I've read suggest that the strength of interference caused by solar panel systems can vary from one installation to the next EVEN when the distance to the source is similar. That var
Tony, There are MANY variables and wiring errors and system layout errors that can contribute to how much RFI is radiated. One issue that Teff communicated to me was that the framing holding the pane
Jim: Tom Simpson (Solar Edge Engineer) will be visiting the site sometime in the near future so I'm hoping he'll address the potential problems you mentioned. The issues you describe may also explain
Tom, aka TJ, is pretty good.....you are correct, he doesnt like Tonys article from Arpil 2020, not sure why, but the retrofit they did at my neighbors was very similar except they used clamp on ferri
James: Jim (K9YC) gave TJ recommendations on the type of chokes that were to be installed on my neighbors installation. However, I'm not sure how much of Jim's design was actually used. Have you had
Tony, My only communication with Solar Edge was with Tefford Reed. I met with him several times, he sent me samples of their cables, asked me to evaluate chokes and to make recommendations. I did, ha
Jim: I can tell you that your recommendations were passed along to Tom Simpson and others in the engineering department so they're aware of your work. Can't thank you enough for your help. Tony -K2MO
James / WW3S: Can you give us an idea on how effective the RFI suppression was on your neighbors Solar Edge system? I'm sure the group would be interested in a before and after RFI signal strength as
I tried sending before and after SDR screenshots, but the reflector rejected them....nearly 30db, the 200 kc optimizer spikes are gone completely. Remember I live in a subdivision, so its noisy anywa
James: Glad to hear that you're able to us HF again so congratulations. I'd be interested in seeing your before and after screenshots so please feel free to send them my way. Thanks, Tony -K2MO On 9/
W1VLF is in a relatively quiet neighborhood. He, too, had loud spikes every 200 kHz, which did go away when they replaced the optimizers. The inverter at his QTH is still noisy, so he is working with
Tony, Regarding your statement below: "We found high levels of RFI on the A/C lines throughout my neighbor's home and that's likely the case with all Solar Edge installations .............since there

And even what is not connected to the system, but nearby. Any radiation from the system can be capacitively coupled or induced in nearby wiring and re-radiated. Grounds can be resonant or not resonan
Hi Jim I agree. The real point of the email was if you know what the source of the noise is I would concentrate on that particular issue. Instead f wandering between inverter, optimizer, then inverte

Paul: The RFI on the home AC lines is identical to the RFI generated by the Solar Edge system. I can't tell you if it's induced or directly injected onto the A/C lines but it's there. More importantl

I agree, but I like magic, so that's my story. Yes, one can actually do real science and come up with answers, but that often involved multiple interrelated phenomena that are best sorted out with ex
Ed: This is no different from the noise change that occurs when the sun goes down, so all it really does is demonstrate that the noise is coming from some part of the system. That's correct. The reas
