Looks like you had your questioned answered. Since you are new to DC wiring, I have another suggestion. Pay attention to wire gauges. 12v systems carry 10x the amperage of a 120v system to provide the same power. Use a wire gauge calculator and don't skimp. Even the 8 gauge to the battery may not be enough depending on the distance to the power unit.
Thanks for the follow up and suggestion. The distance from battery to the control center is only about 5ft. In this case the biggest thing I am planning to power is a laptop and a monitor, then some LED lights and an over head RV max fan. The control unit is 45a max. Couple weeks ago I ran it thru an online calc that suggested 8 or 10 AWG from battery. Is there an online calculator you like over another? I just picked one from the google search.
