Hi Drake, I have done this, or I think what you are asking.
I have AC coupled 2 enphase 190s through a transformer to a VFX-3525 in an offgrid situation. It worked fine. However I did notice when there were very little loads I got what I think is an AC ripple. I would see some lights having I think a 60 cycle flicker. But I don't think that being grid connected you will see any issues. jay peltz power On May 28, 2014, at 2:47 PM, Drake wrote: > Hello Wrenches, > > We put a system in a year ago with an Outback GVFX 3524 with 2205 W of PV and > a Midnite Solar Classic CC.
