Residential Fridge - battery power
We just replaced the Norcold with a residential refrigerator. The question is - if I turn on the inverter will it run the refrigerator without harming the batteries?

Hmmmmm. Maybe I misunderstood the question. If the original poster is asking if the load of a fridge fed through an inverter will hurt the batteries of course not.
The original question was, let's say, not totally clear. It was "I turn on the inverter will it run the refrigerator without harming the batteries"?
There are 2 things that may harm the battery - high current or low SOC.
Feeding the fridge through inverter is neither good nor bad in itself. 12A current @12V is not harmful for 3*90 AH bank. One note on inverters, though. MSW inverters tend to do some harm to motors - they are running hotter - but it's hard to tell how much harm and whether this is worth extra cost of PSW inverter.
He will harm the batteries after a 20-24 hours of running the fridge. The more he does this (i.e. the lower drops the SOC), the more he harms them.
He will not harm the batteries while running the fridge when driving 5-6 hours.
