Unless you accidentally overbuilt your solar system to where you need to burn off the extra electricity (or maybe if you are on the road 8-10hr per day, so the alternator provides free power)...12v operation makes no sense.
On Grid, use 120v.
Off Grid, use propane.
Where 12v can make sense is if you go with a 12v compressor fridge.
- Our 12v fridge rated at 30w once it's down to temperature.
- A 12v heating element for a 3way fridge will run 150-200w and if it's on it's drawing that amount. Given the slow cooling of an absorption fridge, I would expect it to run a larger percentage of the day.
