Regarding SolarEdge or any other company selling and installing Solar 
powered equipment. 

These cases are not the first ones. 

SolarEdge has fixed others so they are RFI quiet.

You can't tell me that SolarEdge doesn't have a test facility or could easily 
create one where they could test their equipment. "They" could then modify 
their equipment to no longer create RFI and from that day forward ALL of 
their systems would have the proper equipment and not create RFI. 

Last year I was in Marshall, MO near the Fitzgibbons Hospital's Solar 
System. It is designed to run this hospital and it is one massive system. 
There is an access gravel road that runs though the middle of the system. I 
slowly went through it while running my Icom IC-706 mobile rig through 1.8 
up through 10M bands. Right in the middle of this system yes it created 
about 2 S units of noise on the 706. Once I was a couple blocks away from 
the system I couldn't hear any noise from the system. While not perfect 
when one considers the size of this solar system vs some individual's 
house system it really wasn't too bad. I am sure due to the location of this 
system that RFI was never a required specification in building this system. 
That picture only shows a very small portion of this system. The Panels 
cover an area that is 800 feet by 600 feet. 

Conclusion SolarEdge could have already permanently solved the problem 
if they wanted to do so.
