Off-Grid Direct Current (DC) refrigeration does not require external venting like propane fuelled refrigeration and units are smaller in physical size especially because the cooling apparatus required for a propane fridge is not required.
When first turned on DC compressor based cool down much faster than propane fuelled refrigeration. Cottagers with DC refrigeration tend to leave their refrigeration units on all the time because they don't have to concern themselves with the cost of propane or running out of propane especially when away from cottage/camp for a week or more.
On the other hand you do require a solar system to support DC refrigeration which can be avoided when you use propane to fuel refrigeration.
