In my city - electrical codes forDC 48v (or higher)require red/black wires inmetal conduit within the home (in attic, walls, etc) andAC does not (can just run the wire). I think this might affect DC vs AC 'bias' beyond just wire/amps/voltage. I've read that this is one of the pros of 'solar panel' inverters - to run AC from panels on roof into attic, you don't need conduit in attic. Codes.... (sigh).
