I imagine rooftop solar could also source DC for the house directly (or via a battery), before hitting the inverter... ?

The main problem I see is educating consumers. Maybe that starts with a standard for DC outlets and plugs that can't be confused with AC... ?

(Now I'm imagining desktop computers with much simpler power supplies; but you'd presumably have to wire for dozens of amps incoming...)
