I had my old 12v system from my barn that has just been sitting on the shelf. I didn’t really know what I wanted to do with it till I started browsing YouTube one day and came across a handful of videos where people built their own portable power stations (or solar generators if you prefer). I thought that would be a great use for my old system. It would give me the ability to have power out back when I’m working where before I would have to either run the generator or I would have to run a lot of extension cords.
