[RFI] Solar Panel RFI in Kings Park, NY - Update

[Tony]

All:

Solar Edge shut down my neighbors solar panel system to test for RFI 
this week. The strength of the noise dropped, but it's still detectable. 
I'm told that the inverter and optimizers are inactive which my neighbor 
confirmed.

The problem with this test is that the power supplies within the 
optimizers remain active since they receive their power from the solar 
panels. The noise is also typical of the type generated by switching 
power supplies.

The next logical step would be to disconnect the power supplies from 
each solar panel to see if the noise goes away. It's something I've 
asked Solar Edge to do for some time now.

Before I make that request, does anyone have any thoughts on what else 
could be generating noise with the system turned off?
