Wrong click on picture . it will zoom up and you can see "DC circuit" in yellow. Below picture info In the 2014 NEC, this practice of a common gutter containing multiple inverter output circuits will be a code violation unless a barrier is installed to separate the inverter output circuit conductors. You Cant mix pv circuits( pv circuit can be a dc or ac... ) With a inverter input or output circuits as it is consider a feed wire . Feed wires aka main power source can >never< share the same raceway with any type of circuit by the way . So if your doing a generator, solar or even utilities hook up aka entry cable don't mix other circuits ) .
">>>PV source circuits <<<<and >>>>PV output circuits<<<<< could >>>>not<<<< be contained in the same raceway, cable tray, cable, outlet box, junction box, or similar fitting as conductors, feeders, or branch circuits of other>>>> non-PV systems<<<<<, unless the conductors of the different systems were separated by a partition. I had a wire gutter/ trough fail inspection on my sol ark which I had to separate my ac and dc circuits with a partition. "
