Trailer Electrical Ground/Frame and Solar
The negative terminal of the battery goes to the frame via 6ga wire. And I think the AC ground goes to the frame when we're not off-grid. I'll wire the MPPT controller with two 6ga wires going to...

Here's what the manual states:
So, after all that I take it as a standard #10 ground wire from the CC enclosure to a Ground Buss, this states D/C Load Center meaning a ground buss in the panel enclosure. The assumption is that the "D/C Load Center" ground has been 'earthened' or connected to a ground rod.
Now how many of you out there connects your R/V's electrical systems "ground buss", if you even have one, to a ground rod, with a #6 wire between the rod and the buss?
Like I said, this is stick & brick code language.

11.3 Grounding
The enclosure of the MPT-3048 is floating with respect to all circuit voltages and may be used with either negatively or positively grounded systems. It may also be used with systems in which neither negative nor positive are grounded, as allowed by NEC 690-41 for systems of less than 50 volts. Most systems are negatively grounded, or utilize an isolated ground to which neither negative nor positive conductors are grounded.
F Do not ground any positive or negative conductor within the enclosure of the MPT-3048. Always do so at a common location in the DC load center, and through a Ground Fault Protection Device (GFPD), to comply with NEC requirements. The equipment grounding conductor attached to the MPT-3048’s grounding lug should be an insulated wire with a minimum size of 10 gauge copper.
! The voltage between ground and the positive and negative connections to the controller must never exceed 100 volts.
For code compliance, basic electrical safety, and enhanced EMI shielding, one copper ground wire must be securely fastened to the enclosure. A lug and bolt are included with the unit and may be fastened to the 1/4” threaded hole in left side of the unit (Figure 11.3.1). The other end of the ground wire is connected to the grounded bus bar within your load center.
