[RFI] Solar Edge RFI in Kings Park, New York. Update September 16, 2018

[NA6MB Mike]

Yes, the sun will still continue to power the inverters.
Shutting off the feed to the mains does not stop the inverters.
They either need to cover the panels so no sun hits the panels or
disconnect the inverters from the panels.
