My battery system is exactly like Don and Carols. The 4 six volt btys are dedicated specifically to the inverter and provide 110 v to all plugs in the coach when not connected to shore power or running on generator. There are two pairs wired in series and then the pairs are joined in parallel to provide 12v to the inverter. My TourMaster and I assume most have a residential refrigerator which only runs on 110v, therefore we ALWAYS need 110v power available. We can use the microwave, toaster, coffee pot,etc.,without being connected to shore power or running the generator. When shore power is unplugged or generator is shut down the inverter takes over instantaneously. The inverter will not run the roof A/C though.

The two 12v deep cycle (coach) btys run lights, water pump, ceiling vent fans, electric step, gas furnace, etc.

Hope this helps rather than confuse the issue.
