The wiring you proposed is fine for the panel to C-box and C-box to charge controller. At 24v output 8ga is all that is needed.
Too often people spec for 99% efficiency with wire sizing and it is overkill that accomplishes nothing. At 12 VDC and a 20' run the voltage drop with 2ga is 0.53% and going to 6ga it is 1.36% - not much difference between a 14.5 VDC charge dropping to 14.49 volts with the thicker cable versus a drop to 14.3 volts.
For the large gauge wire and connectors I found delcity.com to be a great source for my setup.
