Nice use of an in house microgrid. To me the striking thing was how the LED bulbs designed to be plugged into 220VAC 'just work' when plugged into 12VDC; I know this is because of their switchmode power supplies, it's still surprising.

You could consider doing this with "19.5V" (popular with laptops), although many will work just fine from 12V, or power-over-ethernet's 48V.
