All: It appears that some electric vehicle manufactures are eliminating AM radio due RFI generated by EV's. The article below outlines the reasons. It reads in part: /"electromagnetic frequencies gen
All: I just had a conversation with Tom, WJ9H about his noise-free solar panel system. He didn't have all the details, but he did say that it uses YC600 micro-inverters and Silfab solar panels. He wa
Stephanie: Your neighbors system might be one of the few on the market that produce less noise than others so consider yourself lucky. It may still produce noise, but keep in mind that the proximity
minimal noise That is great news Stephanie. Things could have been a lot worse if your neighbor was closer. To give you an idea how bad solar system noise can be, have a look at the video below. It s

All: I just received word from Solar Edge about a prototype Optimizer that's supposed to reduce HF interference caused by their solar panel systems. It's scheduled to be manufactured in November and
You're welcomed anytime Ed. My neighbor and I are good friends so there's no problem gaining access to his installation. Bring your RF probes! Will keep you posted. Tony -K2MO _______________________
All: A few years ago, I posted a video on solar panel RFI and it's affect on HF. Since then, I've heard from many hams who've experienced the same issue. Most send emails but a few post comments on m
Mike: I have firsthand experience with a neighbors Solar Edge system and I can tell you that it does not generate noise once the system shuts down at night. This video shows a comparison between the
Dear Tony - Thank you for the pointer to your excellent videos.Regarding the optimizers... are they shut-down-able or do they always operate if the solar panels are illuminated? 73, W9IP Mike: My nei
All: Solar Edge will be testing their new prototype Optimizer today. The new design is supposed to reduce the RFI associated with their old units. The NPI engineer I spoke with said the test results
Kurt: That's probably my 2016 case you're referring to. Solar Edge installed the EU units years ago which unfortunately did little to quiet the system. They also changed the inverter which also had n
All: When the Solar Edge contractor installed RF chokes on my neighbors solar panel installation, I expected them to start by measuring the level of RFI to establish a benchmark. I also expected that
All: Just heard from SolarEdge regarding the new prototype optimizer. The NPI engineer said the noise test went well and that he recommended the new device for mass production. I don't have any detai
