Found this video last night and thought it was a pretty neat project. This could be a backup power source for a Tiny House for those who have water near them. This setup puts out 56 volts, 10 amps for a total of 560 watts. Now I have yet to see how well it does under load and that will be the real test, but I really like this idea and I think it is simple enough for people to wrap their heads around. This project will cost about $300-$400, but I think it would be a fun tinkering project.
