Last night it was 1 degree colder in the fridge than the night before, and outside temp was a tad warmer. So I think it's still cooling down a little bit as a whole.
All food is happy except for a zuchinni that got buried in a corner and frostbitten by the walls.
I've started looking more at derivatives than instant numbers, and at longer-term data. Here's daily power production before and after the fridge was installed. You can see it's gone up the last 3 days with the fridge's load. Before that, PV production would drop off to a low rate once the batteries were full, often by 11:30 am. Now, the fridge keeps banking solar power.
