This portable solar power generator is built with a 10 watt solar panel, battery, controller, 120w inverter, volt meter, on/off switch and outputs.
It’s large enough for higher capacity jobs yet still very portable and will cost you under $150 to build.
How portable do you want your solar generator to be? Think about how heavy and large it should be? Are you going to use a hand truck to carry around a huge toolbox filled with batteries and a large solar panel or do you want a tiny one that will fit in your glove box? The wiring and concept will be the same for either size so the choice is yours. I wanted something in between that I could carry but still had some decent capacity to do some work.
First I bought a case that would be a good jumping off point that I could fit a 10 watt solar panel on and in. Your case doesn’t have to fit your panel in but I thought it was convenient for me.
