Last winter I purchased an ICECO 12v refrigerator for overlanding in my newly built RTT trailer. You can read about it here ICECO VL45 Portable Refrigerator/Freezer Review | RVB Precision
But with CoVid I've not used it yet. A whole bunch of off road trips got cancelled.
This past week I was able to give it a real workout. On Tuesday AM I hooked it up to a Duracell Group 31, 110Ah AGM battery to chill it to add food on Tuesday evening.
By 3pm it was at 39 degrees and I loaded it up and headed out to northern New Hampshire.
Although I have a 120w portable solar suitcase panel and a Renogy DC to DC charger in the truck, I did not deploy either. All I had charging the battery is 20w of solar through an inexpensive charge controller that was installed simply to keep the aux battery in the truck charged.
I returned Sunday night but left the refrigerator running with food in it as I was to exhausted to unload.
So, from Tuesday AM until Monday AM the refrigerator ran on one group 31, AGM battery with 20w of solar charging. BTW, these panels are flat on the roof of my truck cap. Not angled to follow the sun. All I did was try to keep the truck in the sun throughout the day. The refrigerator is on a slide in the bed of the truck. The cap on my truck is black and gets crazy hot inside. It has no windows that open so I left the rear lid cracked a little bit.
The temperatures in NH during the day were in the upper 80s to low 90s.....at night it was from 54 degrees to 68 degrees.
Weather conditions were mostly sunny but Saturday and Sunday were overcast with periods of rain.
The battery never went below 12.5V !!!!
Totally blew my mind how well this setup worked. Man, does this beat trying to camp in the summer with coolers and ice!
