You can guesstimate an average number by looking up the Energy Star rating of a refrigerator. Many newer refrigerators (obviously depends on size, efficiency, and conditions in which it operates — so I picked one below only as an example) use roughly (in order of) 2 kWh of energy daily. Averaged over a 24-hour day, even when adding a little for inverter inefficiency, power demand should be around 100 watts, which is close to 8 Amps at 12 Volts.
Refrigerators “may” draw close to 1,000 watts for very short periods, but it can’t be that high for very long or else they wouldn’t operate very long on 4 golf-cart batteries.
