[RFI] Update 9/30/16 Solar Panel RFI @ K2MO

[Tony]

All:

Here's the latest update on the solar panel RFI emanating from my 
neighbors home. The SolarEdge system was installed by Solar City on the 
8th of August this year.

On September 12th, Solar City informed me that the RFI case was in the 
hands of SolarEdge, the company who makes the solar system.

On September 29th, I received an email from the installers System 
Monitoring Tech which said the manufacturer, SolarEdge, has been 
dragging their feet; the only response for the past 3 weeks has been 
"the case is being reviewed".

He went on to say that he will present the case to his supervisor to see 
if Solar City can solve the problem themselves. His plan is to apply the 
suppression techniques provided by Tony Brock-Fisher's QST article 
(April, 2016).

Another option would be to install a system that does not use Optimizers 
which seems to be the major cause of RFI. In closing, he said he wasn't 
sure if the responsibility of eliminating RFI lies with his company or 
the manufacturer, Solar Edge.

It seems logical to me that that the responsibility would lie with the 
installer if the installation was found to be at fault, while the 
manufacturer would be responsible if the device doesn't meet FCC standards.

Can anyone clarify the responsibility issue? Is there a case where the 
manufacturer and / or installer were held responsible for causing RFI?
