Higher voltage solar panels?
If I could get a 56v. 310 watt panel for free is there any MPPT charge controllers that will step that down for me? I'm having a hard time googling one. If so is there any downside to using a panel w...

Is 56v a "48v" panel? Some, not many, controllers will do 48-12 to a 12v battery.
Advantage low amps on the panel to controller wire path, so the wires can be thin. Disadvantage, the lower efficiency bucking from 48-12 in the controller.
With the panel free it is all math to see if the controller cost makes the whole set-up "worth it"
Stick houses use 48v and there are now small but useful 48v inverters they get for them. Don't know a lot about it--might be useful in an RV?
