3rd for the MPPT. And, one of the small 12-volt books like the "12v bible" or "12v doctor" to explain some power issues. 20V is more than the batteries should be exposed to in a perfect world, but the amperage is probably more of an issue. And either way, the MPPT controller will give you more useful power than any other type.
Its not that we're a hard crew--just that there's little question about "the way things are done" in a boat sale, unless you've contracted specifically otherwise.
