I’d appreciate your take on the video I posted in comment # 50 about RF tests on various devices, including over air tests and on cable tests. Is this legit or just a sales gimmick?
I can’t tell exactly what waveforms they used and the intensity, but it is generally reasonable to look at susceptibility in this way (conducted and radiated). It’s better if you do it both at the same time, but this is decent info.
I’m not sure this is what they did, but I suspect that it is - but the bottom line is that placing properly rated Metal-Oxide Varistors (MOV’s) or similar device very close to the device on any conductors can be an effective way to protect the device (and some related grounding). Solar Panels have a blocking diode that needs to be protected and can be protected similarly.
Solar panels themselves have some additional vulnerability on the multiple cells, I don’t think this setup would test that issue fully.
