Yes you can dry camp with a residential refrigerator, provided you have solar power, or are willing to listen to your generator run 3-4 hours a day.
I recommend the very quiet solar panels! 400 - 500 watts should work great!
SunElec.com They had a 140 watt 12 volt nominal output solar panel on sale for $229 a few weeks ago. You need something with an aluminum frame, 12 volt output.
The frameless and higher voltage panels are mainly used in homes, where the higher input voltage allows smaller wire size, and it is worth it to string together 4-6 panels, and use the resulting 150 - 750 volt input to the batteryless inverter.
You will also need a PWM controller, mounts, wire, ect.
If you are having the unit built, the manufacture normally charges a arm and leg for all this stuff, they have not learned how to install it very low cost.
Good luck,
Fred.
