    As I develop Glasir, I am going off-grid solar. So right now I’m heavily dependent on a gas generator for running the heavy loads.

    I've got two group 27 batteries I use primarily for the camper at the moment. I have four group 31 hybrid starting/ deep cycle in the semi

    the camper and the semi both have a 12 volt refrigerator.

    the camper can go about 24-30 hours on barriers with no solar. The semi, about 50-55 hours.

    a pair of 100W solar panels from harbor freight will put about 12 amps of power back into the batteries during the day time. I’m pretty sure I need to get that up to no less than 600-700 watts to get them recovered during the daytime.

    that’s just three 250 w panels. Or less if you get a pair of 400w panels.

    so your not talking a big foot print here.

    all your trying to do is get enough energy to power a refrigerator / freezer.
