12 V to 24 V Bank Digram needed ( Ray or any Old Timer Help)

Please if you are a Salesman or vendor Do not wast your time on me. I hate how the Sales vendor have infiltrated this site. ( Forgive me Ray)

I have just seen High Wattage Sine wave inverter 24 volt on the Low price side. I am jumping from 12 volt to 24 Volt for this reason and my well is up and running my last quest is Air conditioning of 1900 square feet i will post data on ever sep of this one.. All of my Pmw controllers will make the switch easily.

I dont think it can be done ,  I may have to drop to 8 batteries. Any advice from the Old Timers is appreciated. Ray Hill Billy Gene, Johann, Big Moe Help. I need a Diagram or a link to a Pic
