Solar Power switch over help.
OK so I'm putting in a solar power system and batteries to run a frig or freezer and some other stuff when I'm in the middle of the desert.
My question is my system will be used to charge the separate batteries I have for this system specifically.
What's the easiest way to use the stuff already wired into the bus. I think the only things I need are the car stereo and the interior lights. It's simple enough to run a separate set of wires to a switch to use those when i want to use my solar/battery side???
