You may also want to cite the 2017 code which does not require the GEC for ungrounded inverters, or rather non transformer isolated inverters.

Fortunately (?) we are still on 2011 here, but 2014 is coming and hopefully AHJs will remain permissive of no additional electrode if the home already has one within 6 feet of the service entrance (which it almost always does).

I just pulled a permit for a residential system and it had a little stamp that had 690.47(D) circled as a requirement. Anyone worked with AHJ's in California who are now requiring this? I am planning to not install the electrode, siting Exception 2 and trying to say that the existing electrode next to the build is "next to the array"?
