I don't see it in your comments. At least that wasn't clear. Anyway, in
that case there is absolutely no reason to use the inverter ground clip.

I guess the thinking is that DC side of the Enphase is grounded and
therefore a separately derived system requiring it's own system grounding.
This is achieved by connecting the GEC

All,
While there is ambiguity in the 2008 NEC in 690.47(C) on the requirements
for system grounding of PV systems, the 2011 NEC in 690.47(C) clarifies the
intent
System grounding requirements.

I would like to remember us all back to 16-20 years ago when
we were required to use a ground cable equal to the
largest conductor in the system. This was typically sized by
the inverter cable at 4/0 copper. I gotta say that was a
really dumb rule.
At that time we were to not create ground

Yes, but that comes from the assumption that the inverter constitutes a

As an aside, why didn't you use approved WEEB's to bond the inverters
to
the rails? This eliminates the ground wire to each inverter. Simpler
IMHO.
I did. It is in my comments.

The panel frames are grounded to mounting rails via WEEBS, rails are
