Group 27 deep cycle battery + 2000W inverter
How long can a group 27 deep cycle battery and 2000W inverter power a full-size refrigerator? Assume that the batter is fully charged. Thanks

Not enough information to hazard a guess.
That being said, I have run a ten year old (not very efficient compared to new ones), 14 cubic foot (smallish “full size”), refrigerator for several days in 75-85 degree ambient temperatures and measured electricity consumption to be 2.0 kilowatt hours per day. Newer, more efficient refrigerators, larger/smaller ones, warmer/cooler environments, all make a difference. Oh, add 10% to cover the inverter.
That’s my beer fridge down in my man cave. 2.2 kWh translates to 183.33 Amp-hours, requiring 4.3 (that is, actually 5) of the common group 27 “marine deep cycle” batteries most travel trailers come with. Your mileage will vary, depending on factors noted above.
