    Stepping 12V up to 37V is going to be horribly inefficient. I think you would need a lot of batteries and even more solar panels.

    And also only try it on the equator.

    Using an inverter is probably the only practical way but the same applies. It won't be efficient.

    They no longer sell them as they were useless.
    We charge ours through an inverter with no problems.

    We found the best way is to top the batteries up everyday rather than letting them run low.
