No way to tell you unless you give us more info.
How many amps AC does the refer unit pull?
How many amps in your house bank?
You AC appliance hits your house bank at 10X the DC rate - SO if its a 3 amp fridge- its pulling 30 AMPs minus inverter losses from your bank every hour it runs.
Is your inverter pure of mod sine wave? (this will have about a 20% effect on run time to 50% depletion)
Hope you make it!
