Re: [RE-wrenches] Enphase AC coupled through autotransformer

Hi drake I've done exactly this, VFX 3524 2 x enphase 190's Worked fine. I didn't like the 60 hz ripple so I removed it. Jay Peltz power Sent from my iPhone On Sep 18, 2014, at 4:46 PM, Drake drake.chamber...@redwoodalliance.org wrote: Hello Wrenches, Has anyone AC coupled an

[RE-wrenches] Enphase AC coupled through autotransformer

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

Re: [RE-wrenches] Enphase AC coupled through autotransformer

The output of a 120/240 volt auto transformer shares neutral with the input when you use to couple a 120 volt device to a 120/240 volt split phase system... there is no isolation because the neutrals are the same connection. I've done AC coupling with auto transformer specifically between
