Reverse of a flying capacitor voltage doubler.... Given chain of 4 batteries: pos---12V---a---12V---b---12V---c---12V---neg Use FET switches to alternately connect 'pos' and 'b', then 'b' and 'neg' to the inverter. You will probably want a good size input capacitor to ride out the FET switch times, and series resistor to limit inrush to the cap.
