Replaced Refrigerator

Even though my old absorption refrigerator functioned correctly in all 3 modes it just struggled to hard in the heat, and wouldn’t keep things cold enough when ever the temperature outside was above 85 degrees.
It was a fairly easy switch almost perfect dimensions. Didn’t have to trim the cabinet at all, just added some wood to screw the mounting screws into, and added some additional insulation around the new refrigerator. Also blocked the lower venting on the exterior door, still have upper venting so compressor heat can vent out.
Got a great deal on Walmarts website for the new refrigerator, almost thought it was too good to be true.
Crossing my fingers that I’ll be happier with the performance of this refrigerator.
I’m running it off a 100ah lithium battery that is charged by 200 watt solar and Renogy DCC30S thinking this should work for me.

I replaced my original Dometic with this model 2? years ago. Been pretty happy with it though it seems to run more frequently than the original when it was in its prime (it finally lost its cool and they don't make these things to be repaired or serviced.)
One thing I think I've figured out is to not pack the fridge too full. There needs to be convective circulation for the thermostat to properly regulate temperature and maintain an even cooling. I use the outdoor part of a wireless indoor/outdoor thermometer to monitor temps even from the truck cab.

100ah and 200watts of solar? That doesn't seem like enough but I don't have that setup and I'm sure others who do, will know better than me.

This model of compressor fridge is designed to be used on boats as well as RVs so is very tolerant. The manual just says "short term inclinations up to 30º are permissible." So I suspect your driveway is safe.
I think your battery/solar system is fine. I ran my original for years with about half that capacity. Really depends on your other loads. My CRX-65 compressor draws 2.5 - 3.5 amps at nominal 12vdc when running.

no need to be super level. These danfoss based fridges all use about 3A when running. On a 85+ day, making 3 meals a day so opening the fridge about 3x5 = 15 times (worst case) I find that it runs about 30% of the time... 8hours x 3A = 24AH. Even with a few other loads, you should be good for 2 days without needing to charge. Do also have a shunt based SOC battery monitor? That will keep you informed as to your battery status.

i have the dometic 75L, and my 200 w solar, and 100w lith batt handled it just fine. mine has 2 lids, so rarely have to access the freezer side when configured that way. i never did a week at 98 deg. though.
