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

If you are lucky .... an hour Likely less
That inverter needs 400 amp hours of battery support
two pair of GC-2 is recommended.. That's 400 amp hours with 200 usable
your group 27 is 100 (bit less) with 20-25 usable.
The fridge.. Well you did not say but look at the watts and divide by 10. yes 10 that's how many amp hours it will suck off the battery. So if it sucks 200 watts then it needs 20 amps of battery power
Both Dometic. and Norcold at one time made RV-Fridges using a ultra-high effiency compressors. 35-40 watts.. at 12 volts that's a bit over 3 amps. Door closed (Seems strange to have to specify door closed but the interior light adds a major draw)
