Old thread I know but .............

An inverter chamges DC to AC so is not applicable in this situation.

Two 12volt batteries can be connected with a series/parallel switch ( just a large solenoid) available from any farm equipment outfit for about $150. Many tractors start on 24volts and run everything else on 12volts.

This switch allows you to charge the batteries independently from a 12volt alternator (or charger) and is wired into the joystick to engage both batteries for 24 volt output.

Vetus also makes a series/parallel switch but last time I checked it was $1500 and not as robust as the one from the tractor shop.
