Guys:
I agree with you on the 'unprotected' tap from the service conductors to the solar AC disconnect, being a possible safety issue for those unfamiliar with solar grid tie.
Hence the 'both line & load sides of this disco may be HOT'
As to length, my inspector and I use the 'same' as service conductors practice. We are still '11 NEC.
FYI, I am not a 'lover' of the line tap; however I have to accept it IF it is compliant.
