[RE-wrenches] Enphase AC coupled through autotransformer

[Drake]

Hello Wrenches,

Has anyone AC coupled an Enphase system to a 120 VAC inverter through 
an autotransformer?

I'm wiring up a small Enphase system now to an Outback GVFX3524. I 
had a concern about the derived neutral possibly causing a ground 
reference problem for the Enphase. It seems that the derived neutral 
should connect to the system neutral through the Outback and create 
the right ground reference.

Has anyone tried AC coupling Enphase to Outback (or other 120 VAC 
inverter) through an autotransformer?

Thanks,

Drake
