- A neighbor of ours was actually running a setup like this. Not sure
- if the lines were part time D.C. part time A.C. or full time D.C. .
- He had also built several small inverters for various individual
- appliances.
-
- Among other things, I understand that standard 120v switches may
- not be appropriate because of D.C. arcing, and I think that it
- would perhaps be a good idea to use non-standard plugs and outlets
- to prevent connection of inappropriate stuff to a DC outlet.
-
- With kids to worry about, it seemed prudent to make our house
- straight A.C. and plunk down the bucks for the inverter.
