Hi Nick,
Last time I checked Evergreen modules don't work with positive ground systems.

I'd worry about putting such a high current in anyway- Enphase's max
input is 10A (max Isc 12A) while the Evergreen Imp is 11.69 for their 215W.

Thanks Jay:
That is true
According to the Enphase website (/support/faqs):
The Enphase Microinverter manual states that the device is positively
grounded. Don't most PV modules have negative grounds? Is this a problem for
Enphase?
Enphase made the decision to positively ground its microinverters to
minimize corrosion.

A GEC with no splices, or only irreversable splices, has only two ends. If you
need to find them to check their integrity, you know where to look.
No argument about acorn clamps. Exothermic welding might someday be required.

Yes, Enphase bonds the DC positive to ground in their inverters. This allows
them to work with all modules, including SunPower.

According to the 2005 NEC 250.64(C), the GEC for an AC system needs to be
continuous without splices unless they are irreversible

I believe the AC GEC runs from; the point where the ungrounded
current
: [RE-wrenches] GEC for Enphase inverters
The code does require the GEC to be continuous (250.64C), and I believe
that the AC EGC for the Enphase metal inverter cases is in fact the same as the
DC GEC since the point of system bonding on the DC side is inside the inverter.

It seems to me that William's original question of where does the EGC stop, and
the GEC begin, all depends on whether the Enphase inverters bond negative to
ground internally.
Did we ever get an answer from Enphase?
If they don't, then I think by definition in article 100, we would only have an
