Your low voltage storage is battery! They are generally NOT adequate. I use Hawker 60 amp hour deep cycle which new cost something like $500 each I think. These prodive 12 volts for the MGE Pulser EL4 and that will provide something like an hour or so for a standard desktop machine.
If you need something where only 24V is present then likely your _only_ solution in a UPS for short term while you get a genset running. Look in the solar power area. If you are running ultra low power consumption such as with an Atom powered device then a big honking battery can run an inverter for quite a while but in the end you still need something like a genset.
