  • A variable resistor is connected to the output of a solar panel and the voltage and current are plotted along with the power.



    Great for hunters, Preppers or as a portable power generator. Denver Colorado. I have a good friend who builds these for $1850.00. Twice the power of catalogue kits for almost half the price! This is my favorite portable kit ever.

    20 cabins lighting might be an exaduration but the rest is true! Haha
