jpc, as I best recall when I used a killawatt meter for 24 hours on my small Haier fridge it was only like 35 Amp Hours per day (depends on temp and how often door was opened) and after the initial start up surge it drew less then an amp (that's recall no warranty) so your figures don't surprise me all that much. While it was overkill I installed a 2 KW off grid PSW Inverter. I have oftened dry camped days at a time and I run the Haier 24/7 plus the usual water pump and vent fans and LED lights etc or occasional furnace and my solar keeps up.
