Under the NEC or Not?

[Little Bill]

Labeled. Equipment or materials to which has been attached a label, symbol, or other identifying mark of an organization that is acceptable to the authority having jurisdiction and concerned with product evaluation, that maintains periodic inspection of production of labeled equipment or materials, and by whose labeling the manufacturer indicates compliance with appropriate standards or performance in a specified manner.

Ain't that what I said?

How about battery powered smoke alarms then?

They are "installed" yet electrically, are a self contained unit. Same with previously mentioned landscape lights.

I might be able to come up with other similar examples.

Yup. 90.2 says that the NEC applies to all these. But, as with the self-contained solar attic fan, it's nearly impossible to imagine how one could violate the NEC in the process of installing them.

To put it another way, the question has been off the mark from the start. It isn't really "Under the NEC or Not?" It's more like "Does the NEC have anything (important) to say about this?" With the OP's product, it's very little, and certainly a lot less than the inspector was initially suggesting.
