We are often plugged in to a 20 amp outlet. That runs our A/C just fine with our water heater and refer on gas. My question: Can I run my refer on 12v while hooked to shore power and one solar? Or is it still going to be better to run it on gas? My goal is to save some propane if possible.
Depending on the model fridge, it looks like the wattage used in either 12 volts or 120 volts is the same, the only difference is that 175 watts at 12 volts would require your converter to work harder as it tries to keep up with the 15 amp draw.
I think you are better off keeping it on 120 volts.

But a 20 amp service is not going to hold my A/C and refer together. That's why I have to run my refer on gas. If it would work on DC it would save me a lot of propane. It does make a lot of sense that it would require the converter to work harder, but is that acceptable?
The solar would help a bit charging the battery but the converter that runs off of 120 volts would probably kick in thus being a draw as same as or more than the fridge on 120 depending on what state of charge it was putting out. The charger would get warm in doing so thus not the most efficient way to run things as the warm means wasted energy.
Is it possible to run a second extension cord from your source on a different circuit? If so at the rear of the fridge you can unplug it from the trailer and into this separate circuit.
