On a small scale (LED lights, receptacles, RV sized refrigerator, laptop and TV's) it can work very well, but when you get into larger loads (AC, heat, cooking, laundry, etc) the efficiency completely breaks down.
I don't know how large of a load you're trying to power, but the build I posted can be increased 10x in size just by adding more panels and batteries (up to 1100watts)

Good luck! I hope it works out for you
