Thanks for the advice. I'm not ready to have huge battery bank, don't really want to give up that much real estate or $$$.
I like that Samlex and thought just that it was "easy peasy" and you answered my other question without asking, "Do i take the entire input to the 12 v panel off or just a couple of circuits?" I read "12 volt side of life" and I see that's what he did. Also looked at
