Kurt,
You definitely need the dedicated branch circuit protection. Beyond
that, it's up to your local AHJ. Same for the labeling. Of course, NEC
690.54 and 690.56B do require a label at the point of interconnection.
See Ya!

The NEC provides for, and the AHJs have accepted the use of the
connectors as a form of disconnect. Of course, each branch is also
connected to a dedicated branch overcurrent device (circuit breaker).
On the DC side, since only one module is connected to each inverter,
the connectors also serve as a means of disconnect. The DC wiring
does not enter the building, so a separate DC disconnect is not required.
Right, no problems foreseen there.
What specific questions do you have about labeling?
Five small arrays, each on a different structure, feeding one production
meter (located on one of the structures or perhaps on a separate
outbuilding.) Do I put a small breaker/disconnect (I'm thinking a
2-space 3R panel) on each structure and label (how)?
thanks...
