You hit the nail on the head. The migration of all our high-power systems to HV DC is the topic of my book (EV's, Solar', heatpumps, and all modern power supplies). Any power device that uses "variable speed" such as new airconditioners and other appliances are internally using 365 VDC which is a great place to dump cheap DIY solar. And to marry with our EV batteries.
All the early electrification systems were DC. It was standard practice to have 115 volts DC (not AC) in homes. All the lights, switches, and other appliances were DC. For many decades, many appliances still ran on AC or DC.
If you find an old enough house whose wiring has not been upgraded, it may already be wired and DC-rated. :-)
