[RE-wrenches] Enphase noise interference to reporting; use ferrites

[Jerry Shafer]

Wrenches
Noise in the AC circuits and Enphase is nothing new, when they adapted the
new frequency this was in part to get away from the noise so it sounds like
they still have a problem. I have seen a variety of new products effect the
data stream.
