DC only alarm panel

["Techvoid" <not@xxxxxxxxxxxx>]

Hola
what small alarm panel can be used with 12vdc battery power only with a
solar charger?
what sized battery and what charger have you used or seen in this type app?
sunny deep south us.
will I still get a power out trouble and will this cause any problems?
read where some guy called jiminex said the fbi xl2 would not cause trbl if
a jumper was installed.  where does the jumper go?  any other panels that
would work?
3 doors and a motion and of course an audible notification appliance.
