We have a res fridge as well and boondock a lot. We see about 180 watts base load with internet routers and other items running. We have 600AH of LIFPO batteries and 4 350watt solar panels and a 3k pure sine wave whole rig inverter (Victron Multiplus II, 4) MPPT controllers and a 30 Amp truck charger). We also have a 2500 watt generator just in case. I decided to leave the 1000watt inverter for the fridge as a backup, 2 is 1, 1 is none as they say! We can run for a day with no change of lifestyle and consume 40-50% of our batteries. I am considering adding 2 more batteries because we recharge to 100% in 4-5hrs. I am not sure about running AC, I suppose I could for a few hours to take the heat out in the afternoon. Usually about 1pm the batts are charged and the AC could use the excess solar we can't store currently. So, do your power budget before purchasing your equipment. If I had to do it over, I would buy larger batteries rather than 100AH LIFPO batteries.
