I have an electric wheelchair that contains 2-12v batteries. the charger has 115v/230vac input & 24vdc/5a output. what do i need to get to be able to install a solar charge / battery maintain system?

One or more panels delivering more than 30V plus a proper solar charge controller.
A 12V panel usually gives out around 18V with no load, so you either need two or a 24V panel.
The solar charge controller will take care of the actual charging for you.
Please keep in mind that you should not try solar and mains charging at the same time unless you add the proper protection circuits for this.
