[RE-wrenches] AC Coupled + CC Grid Feed Input

[Drake]

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. The system owner would now like 
to expand the system by another 6 modules.

Our tentative plan is to AC couple 6 Enphase  M-215s powered by 6 REC 
255 W modules to the Outback. This way, the GVFX 3524 would be 
selling power on its own while simultaneously feeding power back into 
the grid through its transfer switch.

The plan is to drop the voltage to 120 V using an autotransformer 
before feeding the power into the protected loads panel for AC coupling.

Has anyone tried this configuration? Can anyone see any problems?

Thanks,

Drake
