    Off Grid Power Supply

    Nice design and well done. I do suggest the use of fuses or DC circuit breakers though. Stuff happens and it could all go up in smoke. I imagine the inverter has some built in current protection but it wouldn't hurt to fuse it. And I would fuse that DC socket and probably the AC inlet (and/or DC out between charger and battery) as well. While your design could be capable of carrying a hefty amount of current, the limitations of the 35ah battery and 800 watt inverter, I would say 15 amp fuses should suffice. Maybe 20 amp if you're running heavier duty things like drills or saws, etc. (I'm 60 and I've worked in a power plant for nearly 40 years.. I've seen things burn up.) Other than that, nice job!
