I have a couple UPS systems that were replaced from work that I use. I also have some spare mini lead acid batteries I keep around for projects that I could probably rig something together that would last me a couple weeks or so. I've wanted to play with some off grid independent solar systems just for this kind of purpose. I've played with them in grad school. Just hard to justify spending $500 on a panel and equipment when I'm obviously in no type of danger zone.
