[RFI] Enphase

[K9MA]

My next door neighbors installed an Enphase system last year. I had the 
installer put ferrite cores on the wiring. The system is about 20 meters 
from my tower. I've detected no RFI from it. Whether the ferrites were 
necessary is unknown. However, I checked out a couple other Enphase 
systems in the neighborhood with portable equipment, and detected no RFI.
