Hi All, Our 2015 Discovery 40E has 6- 6V AGM batteries with a 2800 watt inverter. We have a Whirlpool side by side fridge running off the inverter when not plugged in. Can I hear from owners with si...

A modern residential fridge uses somewhere in the general vicinity of 1 kWh per day, perhaps a little more. A single 6V golf cart battery store around 1.3 kWh of energy, of which around half is usable. A little rough arithmetic suggests that around three days would be a not unreasonable rough expectation. Anything more precise would require measuring the power requirements of your particular setup.
An accurate reply for just the refer but you cannot turn everything else off that uses 12v power. My 21cuft refer uses 96 total watts when running on a PSW inverter if I turn the ice maker off and it runs a little less than half the time... 1.0 kWH as estimated above. You will have 2-4 amps of parasitic load 24/7 in a big MH that you cannot get rid of. Add some lights, water pump, TV and charging phones you are better off running the generator any time you use the microwave or coffee maker... one hour per day should be enough to keep the batteries up assuming a 100 amp charger.
