Ed,
I agree completely! Thank you for the reminder! Solar Edge is treating
the Amateur community very well here. Sending out engineers is far
beyond what most other companies are doing.
73s and thanks,

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.

Subject: [RFI] Solar Panel RFI Video
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.
