The devices probably don't exceed the limits for AC-mains conducted emissions <30 MHz, but they may exceed the radiated emissions limits above 30 MHz, which they are expected to meet.

Ed:

That's a wonderful idea. In addition to an evaluation, I think it would 
benefit us all if the ARRL would collaborate with the RF engineers at 
Solar Edge. I met them in person recently and they are open to 
suggestions. Tefford Reed is the senior engineer who assessed the RFI at 
my location and is now responsible for coming up with a solution.

His assessment was that their usual RFI suppression methods were not 
enough to eliminate the noise in my case which is why their looking at 
everything from improved RFI chokes to the infamous RFI absorbing foam.
