I did a test when we first got ours, ran the Fridge for 36 Hours on the two size 31 12V batteries and battery voltage was still at 12.6. Now nothing else was in use so fridge was only load. This is with a Whirlpool fridge, different brands might have a different power draw.


If battery voltage was the same after 36 hours, then something had to be charging the batteries. Solar panels?

No Solar or Shore power. Our Whirlpool is a very low draw fridge, plus it only draws power when the compressor is running, per the Inverter Remote Control draws 11 amps when running.

Hmmm
I replaced our failed legacy Fridge with an Apt size Fridge and the longest time it’s been off between Campgrounds is 8 hours and the Ice Cream stays Frozen. Of course we Don’t open it while on the road.
Not sure why there’s a problem unless maybe there’s not much in the Fridge.

Our 21 cuft Whirlpool draws 8 amps DC measured before the inverter…96 watts or 1 amp AC. It runs less than 50% of the time or 1.3 KW/day. One good 12V battery will run it 12-16 hours before needing recharged. A properly installed residential should come with a 1000W inverter and 2 extra batteries and Yes, your tuck shouldn’t have any problems beeping the batteries up, even with the small 12V charging wires.
OMG, a second alternator or a dc-dc converter to charge 8 amps part of the time…stay on the porch.

PS: we dry camp most of the summer and a residential refrigerator is my best mod ever.

I was worried about this also before we bought our Pinnacle with the residential fridge. No problems whatsoever and one of the best things about it, Is that it will cool down in about an hour compared to 6-8 hours. And that is without being plugged into electricity. We have 2 Interstate batteries. We drive up to 8 hours sometimes and the fridge and freezer are cold as it should be. Make sure your inverter is turned on.
