    This system will use the solar panel and the wind generator to charge two 12 volt batteries that will power the trawl motor and the starter of the main motor. The system will have a built in switching mechanism that will automatically sense the state of the batteries, in which case it will switch the load from the lowest charged battery to the highest charged battery, then proceed to charge the discharged battery.

    So the solar panel will charge the two batteries and what I want to do is have two cells available, but have a circuit pull from only one cell at a time, switching to the next fresh cell when the currently used cells voltage drops to a certain level.

    So where's your schematic?
