Operation of the gas absorption refrigerator from the inverter

Yahoo Message Number: 75500
Below describes one approach for an easy hookup to power the refrigerator from the inverter.
In the photos section are 3 pictures entitled `Refrigerator operating on Inverter' - the receptacle below the ceiling cabinets next to the refrigerator, the topside of the receptacle box showing the yellow romex cable addition after the panel has been removed, and the yellow romex terminated in the receptacle where the refrigerator is plugged in. This latter receptacle had the upper and lower outlets isolated by removing the links. The existing wires were connected to one outlet and the new yellow romex wires to the other outlet. The face was marked S (shore or generator) and I (inverter). The romex cable run was about 3 feet and was easily routed between the two existing receptacles by cutting a small slot in the styrofoam above the receptacle that the refrigerator plugs into.
Operation is simple.

Either driving or parked, turning the inverter on will allow the refrigerator to operate from the inverter. Even if you don't have roof mounted solar panels, while the engine is operating, the alternator will charge the house battery bank which drives the inverter.
This should reduce propane consumption.
For night operation, if shore power is connected or the generator is operated, the inverter circuit breaker in the main panel is turned on and the AC passes through the inverter to the receptacles, one of which now powers the refrigerator.
The down side is the refrigerator current draw of 2.5 amps reduces the overall current available for the other receptacles. That can be remedied, if needed, by placing the refrigerator plug in the other outlet which is connected to its own CB in the main panel. The refrigerator can always be operated solely on batteries.
