I have had good luck with some of my servers using a xantrex inverter/charger and a pile of wal-mart car batteries. It's not pretty but I have had no power drops in a couple of years. Since the unit is designed for RVs etc, it will keep the 12v pile charged even in the face of 12v drain, so you can drive both 120vac and 12vdc loads off the same setup. It will charge the batteries when they need it and ac is available, and float them after they are charged, and use the batteries to provide ac if the mains ac disappears. You decide how big a pile of batteries to attach...
