So, my wife and I have a 2020 Solitude 382WB-R that we have owned since June of 2020. The "R" indicates residential refrigerator, which is the 110V Samsung that runs off of a 2000W inverter when on battery power.

We were on a month long trip recently from our home in Alabama to Elkhart and the UP of Michigan. On the return trip home, we stayed at a park that only had 30A service. It was hot, so I tried running one air conditioner and just the fan on the other AC. Blew the breaker at the pedestal, of course. Reset the breaker and killed the fan only AC.

The Samsung has a temperature display for the freezer and refrigerator sections on the inside upper frame that is visible when the doors are open. After the power outage, we opened the fridge doors and YIKES, the freezer was at 29, with the fridge at 58 or so. Wondering if the power outage had caused a malfunction in the refrigerator, I cycled the fridge breaker at the inside panel. Now the fridge temp is 78!

I didn't have a large cooler with me to save the food in the fridge, so off to the closest Wally World, which was about an hour round trip. When I got back, all was normal: -2 on the freezer, 38 on the fridge.

Inverter/battery problem? No, I checked my Victron when we arrived at the campground and was only down 21 Ah after a 6 hour trip. I have two new 6V GC batteries; 235 Ah, so OK there. Water levels were fine.

Long story short, it seems that even if the Samsung is at normal operating internal temperatures, when 110V power is removed and returned, the thermocouples/electronics reset and it takes some time for them to return to the actual temperature of the inside compartments.

I tested and verified this down the road. So if you remove shore power before turning the inverter on, or turn the inverter off before connecting to shore power, you will probably experience this anomaly. How we missed this in over two years of ownership is beyond me. I am only posting this so someone doesn't freak out if this happens to you.

Everything was fine the rest of the trip, inverter or shore power.
