Looking at the energy star sticker for that model refrigerator and assuming 85 percent efficiency on your inverter you should only be using around 90ah out of your batteries per 24 hour day. As a result, if there were no other items being powered by our batteries you should be able to get approximately a day on the batteries before hitting the 50 percent state of charge figure.
How long do your batteries last without the refrigerator running? Do you have an amp meter by any chance so you can see what else might be drawing from the batteries, and how much they draw? Any chance the inverter is trying to power the water heater or some other high drain item?
