The Solar Controller Charger that comes with the Omni / Magnitude is a 10AMP model. It can handle about 200 Watts. That might be enough but you could consider replacing it with a 30AMP model and installing two 200 Watt panels.

I use two Renogy 160 Watt flexible panels that do a pretty good job. Once the the fridge is cooled down, it isn't going to draw a lot of power. If you minimize opening the doors and it is not too hot, a couple solar panels with the 4 batteries could be all you need. The solar panels should be able to keep the batteries charged during the day with the Inverter powering the fridge.

You can also set the generator to Auto Start if the batteries drop down below 11.8V and they should charge back up fairly quickly.

I have shut off the Inverter over night when boondocked one night. The fridge was full and cold and it stayed cold over night.

Thank you for the comments. I did read your write up on adding two additional batteries, which I would do.

Is your setup enough to power the fridge on a sunny day? Will it drain the four batteries if you leave the inverter on overnight?

Thanks again, this is very helpful.
