nighttime not much cooler. Not as hot as the tropics in summer, but sure feels like it. Also keep in mind that this is a 24V system, so 50 AH is like 100 AH on a 12V.

The refrig system is a Glacier Bay MicroHPS holding plate system, vacuum panel insulated on 4 of 6 sides, 6 - 10 inches of XPS foam on the other two. On the refrigerator, the main load is cooling drinks. If you just leave the door closed and never put anything in, it runs about 40 minutes every 32 hours. However in the inhuman conditions here I drink 2+ gallons of refrigerated fluids a day, cooling those and retrieving them is expensive in BTUs.
