Hello Wrenches,<br><br>
Has anyone AC coupled an Enphase system to a 120 VAC inverter through an
autotransformer? <br><br>
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. <br><br>
Has anyone tried AC coupling Enphase to Outback (or other 120 VAC
inverter) through an autotransformer? <br><br>
Thanks,<br><br>
