So, my new house... it already has an entire 12v system!!! I found out when I removed drywall downstairs re-doing a closet!! One thing was marked 12v one was marked 110. I also found out when I started removing light fixtures and some of hte bulbs said '12v'.

So in every room that house a 110v light there is a 12v next to it Wahooo!

I need to find out where he planned/stored his batteries or if he just used the generator and converter to run 12v.

This is awesome! I`m so excited.
Heat will be wood and propane (soon), generator can run the well, hot water propane, lights 110 or 12v,... we can go a month or so w/out power LOL Saweet!
