What I have is a 12V DC battery bank (150 AH) feeding all my radio
equipment - transceivers, scanners, processors), a 1500 VA UPS for the
desktop computer and printer, and a 500 VA UPS for the phones and
digital distribution system.  The charger for the battery system (which
can handle full load if the batteries fail) and the laptop supply are
fed off the mains.  That system can and has powered the radio room for
several hours with less than 1 volt drop in the nominal 12-volt system.
