2022 View 12v Refrig on batteries only run time

[DonSW]

Hello from Arizona, we tested our 12 v compressor refrigerator on the View 24D for three days using only solar and two lithium batteries. We set the refrigerator to night mode on the low setting and it ran for three days depleting the batteries to 85%. The outside temperature was over 100 degrees and the refrigerator maintained 42 degrees and the freezer at 32. In Arizona the solar seems to work well with 300 amps on the roof.

We returned from a trip to BC and the PNW last Sunday. We only boondocked one night on this trip, although we had originally planned for more. Our 2020 Navion 24V has 300w of solar, 220Ah of LiFePO batteries, a 2000w inverter-charger, a 12v fridge, one induction and one propane burner, a convection-microwave, a 3600w propane generator, a propane furnace, a Truma water heater, and a heat pump/AC. The night we boondocked, the temp got down to 40 degrees, so we set the furnace at 60. We used the convection-microwave and propane burner to fix dinner, the fridge was on the night setting, the pump ran every time we used a faucet or toilet, and the furnace began running intermittently after midnight. Of course, like every RV, the propane detector draws 12v power 24/7. The next morning, we again used the conv-micro to fix breakfast. The battery voltage had dropped from 13.7v to 12.6v, so we never needed the generator. That day, we drove 290 miles in bright sunshine, so the batteries were fully charged by the time we stopped for lunch.

The only time we have ever used the generator while camping was in a completely shaded campsite at 10,000' with nighttime temps in the 30's. So, the panels received virtually no solar during the day after we arrived, the furnace ran most of two nights, the tank heaters were on at night, and we had the normal draw from the water pump, propane detector, lights, etc. Just used the propane burner for the two dinners and breakfasts; no induction or conv-micro use (we use a pour-through coffee maker when dry camping). The batteries needed immediate charging before using even the water pump on the second morning, so the generator ran for an hour.

BTW, we LOVE our 12v fridge after a TT and a fifth wheel with propane-AC fridges. We were able to keep a half gallon of Tillamook ice cream frozen after stopping at the Tillamook Creamery in Oregon. Couldn't do that with either absorption fridge!

When we boondock in cold weather and need to run our 12vdc-only fridge and our furnace, we bring an Ecoflow Delta 1200 solar battery to augment our house AGMs. We plug the whole coach into the AC outlet of the Ecoflow via a 30-t0-20 amp adapter plug and begin the night with the coach thinking it's plugged into shore power. This setup runs for about 8-9 hours depending on the outside temp and furnace setting (which we usually set to 68 degrees.)

Once the Ecoflow runs out of power and shuts down, then the house batteries kick in at around 3 or 4 AM. They then have no trouble keeping the food cold and the coach warm until our solar panels kick in and we're good for the rest of the day.

Once it begins to get dark on the second evening, we run the genny for about an hour to recharge the Ecoflow and begin the routine again.

Thanks to everyone for the input and experience. It puts our mind at ease.

You're after our heart now
