In order to achieve the max PV input for a MPPT on the 12000XP, it seems you need to parallel 3 strings in a combiner box. In that case the amps will likely be over the max for 10 AWG wire, and so 8 AWG wire would likely be needed.
Do the PV inputs on the 12000XP (v2) support 8 AWG THWN wire? And if not, how else could you parallel 3 strings in order to get closer to the max usable solar input of 35A ?
