[RE-wrenches] AC Coupling Situation

[Jason Szumlanski]

What brand of inverter are your using for the off-grid inverter. SMA has
addressed this issue with the Sunny Island. I'm looking at an all-SMA
option for a new installation, and also an SMA-Enphase AC Coupled system,
so I'll be interested to see what others with more AC coupling experience
have to say.
