Every fridge comes with an energy guide sticker. A Haier 9.8-cu ft Top-Freezer uses 327 kWh of power per year. This translates to 895 Wh per day. This is about 37 AH per day.

That's the fridge I'm installing. Will only be on inverter to cool down before leaving on a trip. We don't boondock, always have shore power. So I think my existing batteries can handle about 10 hours overnight to do cool down.
