looking for a way of transfering dc battery power to ac power?

Answer 1

DC to AC Power inverter. For low watt applications there are several available. I've even seen them at wal-mart, they usually plug into the cigarette lighter but they make adapters to hook them directly to a 12 volt battery. You'll need to know how many watts you need, and what voltage DC power source you'll be using before you buy one.

Answer 2

The device that does this is commonly called an INVERTER. Without knowing what the DC input voltage is, and what AC voltage would be the output, I can't give you a specific inverter type.
