We put in a NovaKool 9.1cuft DC compressor fridge in a new build. Vitri is supposed to be the same or better quality. I think both use the Danfoss compressor.
Our battery bank is smaller than yours (250AH) but our solar larger (1100 watts). We also have the EU2000i for backup.
As a point of reference, I am seeing about 600 watt-hr per 24 hour period being used by the refrigerator when I set it to a little colder than the default middle setting (so the fridge portion is about 33 degrees and the freezer gets to 0 F).
So with no input from solar, gen, or alternator, the fridge would drain your bank to 50% in about three days. We always get 100 to 200 watts of solar though even on rainy days.
