I am trying to get some electricity to the Cargo Home without having to run extension cords. Here is the start of my new Solar System. I am mounting the components on a plywood board. In the photo, you can see my four Battle Born 12v Lithium-Ion Batteries. That is 400 Amp Hours of goodness. I will go into greater detail as I get this wired up but as it sits I have 800 Watt Hours of solar panels, it will be set up as a 24volt system.
