Best bet is to get 4 6v deep cycle batteries connect in series and connect a high quality power supply capable of supporting planned load and set output voltage to the selected 'float' voltage This will give you a setup which depending on batter rating could give you several days of backup power

I used an analog Astron 35A power supply (RS-35M) for its raw DC and series pass transistors with its regulator board replaced with a (now obsolete) AA Engineering smart charger board. This used a uC3906 IC for control. Capacity wise this was actually overkill for my application as the charger could supply the total load.

That said, if someone wants to pursue something similar I can recommend their power supplies with their "smart charger" modules. (http://iotaengineering.com/power.htm)
