I don't have or need one with my current vintage of rigs, but I was pondering a question that came up about integrating solar with one.
Do DC-DC chargers float their ground or are they common to chassis ground?
What lead to this question was pondering how to get the solar to also charge the starting batteries. So far in my thinking I'm at needing at least three and maybe four high current / low voltage drop wires along with one or two DC-DC chargers. If only one then an older single-sense type ACR/VSR would be needed for the solar to truck battery isolation/connection.
If they are common then that's down to three such wires or cables. Which is still a heavy price to pay for that functionality. There has to be a better way that I've not figured out.
