Hi Matt, I can’t tell you the reason but I had the same problem on my Outback VFX. I didn’t put it on a O scope, but sure looked like a 60 cycle flicker to me.
On my system of 2 enphase, when the loads exceeded the output of the enphase the flicker when away. But only 2 isn’t very real world. In the end it was just a test for me, and it didn’t work. jay peltz power > On Sep 21, 2015, at 6:18 AM, Matt Sherald <[email protected]> wrote: > > I wired an Enphase string into my critical loads panel at my shop.
