I'm confused looking at the 2017 NEC:
(B) Identification and Grouping. PV source circuits and
PV output circuits shall not be contained in the same raceway,
cable tray, cable, outlet box, junction box, or similar fitting as
conductors, feeders, branch circuits of other non-PV systems,
or inverter output circuits, unless the conductors of the differ‐
ent systems are separated by a partition. PV system circuit
conductors shall be identified and grouped as required by
690.31(B)(1) through (2). The means of identification shall be
permitted by separate color coding, marking tape, tagging, or
other approved means.


Can the PV DC input and AC Grid and Load wiring be in the same metal electrical enclosure?
 
I am working on an install and have seen this as well. Note the part about "partition". As I recall, if you read further, grouping and separation can serve as the partition if properly marked.

Note, since the PV is required to be in a metal conduit, I have been thinking that I would enter the house with metal flex, go into the wireway box, keep the PV in the flex as the partition, and then up into the inverter. But on second though, I am thinking, just run the flex right to the inverter.
