You can power your panel with another 12 battery.  Hook it straight up
to the AC input.  That way your solar panel only needs to charge the
first battery.  The system will keep the other charged.  Any panel will
do, but the smaller ones tend to draw less in the way of power.  On some
panels you may wind up with a "brown out" condition if the input voltage
isn't high enough so if your solar charger is having a problem
maintaining at least 13.1 to 13.4 VDC the keypad's could go into AC
trouble mode.  I think you'll have a better chance with the FBI XL-2
product.  It uses a 12VAC transformer rather than the standard 16VAC one.
