[RFI] Solar Panel RFI Video

[Hare, Ed W1RFI]

We have found Solar Edge to be receptive and interested in resolving the problems from their existing design.  Keep in mind that the device is an unintentional emitter and as such, subject to conducted emissions limits below 30 MHz ONLY on the lines connected to AC mains and subject to radiated emissions limits above 30 MHz.   If the noise being conducted onto the AC mains is below the limits, radiated noise below 30 MHz is legal unless it causes harmful interference.  If it does, it is the responsibility of the actual operator of the device to resolve the harmful interference. The manufacturer is required only to meet authorization requirements, test the design in a lab environment, have ongoing production meet the limits as found in lab testing and to label the equipment.

Although I think that in the long run, their choosing a case-by-case resolution will not work out well for them, I do note that if every manufacturer of products responded to complaints with full cooperation and even site visits by their engineers, we'd all be pretty delighted, so keep this in mind if you have any need to work with Solar Edge.

Most of the SolarEdge house rewire jobs I have had around me solved the problem on the first attempt.  One took about four visits before it was finally solved.  On that final visit an engineer from SolarEdge came out.
He discovered that they missed a couple of the optimizers.  Even one unfiltered optimizer will cause RFI 100s of feet away.  So, keep after them since they probably missed at least one optimizer.

All:

I recorded a short video that shows the type of solar panel RFI I've been experiencing from my neighbors Solar Edge installation. Solar Edge installed RFI suppression a few weeks ago which unfortunately did little to reduce the level of interference. The companies field engineer will be flying out to inspect the work the installers did in the next week or two.

I thought this might help others to recognize solar panel issues.
