residential refrigerator
In my 2007 Discovery we decided we would replace the Norcold 4000 series with a 18 CF Samsung. It is now in and it took less than 2 hours to obtain the desired temp. When running it pulls 16 amps of 1...

I think you will find that it will not need 16 amps once it's cooled down. The DC compressors in a Samsung do not need a PSW inverter and both of them (freezer and refer) must be running. My 21 cuft EnergyStar Whirlpool only draws 8 amps when running... less than a 100W light bulb. After a year I estimate the duty cycle at 50 percent or LESS.
I put mine on it's own power system... four 125AH batteries, 1000W PSW inverter, 100Amp charger and a transfer switch. I can go over 36 hours before the batteries get to 50 percent if I turn the ice maker off. Two batteries should get you 24 hours before needing to be charged.
My inverter shuts down at 11.7V... well below the 50 percent point that you should charge your batteries.
Your numbers closely reflect ours. Our duty cycle is a little less and our current draw is around 1 to 1.1 amps at 120 with the compressor on. We have a fairly robust solar system so it's not really an issue. Too many days no sun and we run the genny but we tend to use the genny during meal times anyway so the batteries stay reasonably charged.
