Wiring was free air until it got near the disconnect, then the
positive wires entered an open 3' section of FNMC (no strain relief or

1. Running the positive and negative wires through separate conduit
violates 300.3, and could cause eddy currents in the combiner/disc boxes.
You won't have a whole lot of eddy current in nonmetallic conduit.
This sounds more like it's being used as wire protection than as
conduit. Not sure where that fits (if at all.)
