Recommended Inverter With Transfer Switch To Power A Residential Fridge

Question:

I have an RV with 50amp electrical although often only hooked up to 30 amp service. I recently had a 20 year old Norcold refrigerator go out. I am in the process of putting in a residential unit. I would like an inverter that will handle the frig only. There is ac that is shore/generator powered in the compartment the frig is going in. Is there an inverter that will sense whether ac is present at this outlet and pass it through or whether no ac is present and will run off the house battery? I do not need a charger as the house battery will charge from shore/generator and not sure two chargers on the battery is a good idea. Have not done the measurements but the AC line from inverter may be a little over 15 feet once cable is run. Frig will sit in a slide out. I have looked at the Go Power units you have online but the ATS, charger inverter seems a bit much. Some of the others dont seem to have an ats. Is there a seperate ats I would need? sorry if I seem confused ..... but I am lol

Conventional refrigerators typically have a starting wattage of 800-1200 watt-hours/day, and a running wattage of around 150-watt hours/day. Refrigerators are reactive devices that require additional power to start because they contain an electric motor, but significantly fewer watts to run as they remain on. Because of this I recommend the Progressive Dynamics Pure Sine Wave Inverter w/ Transfer Switch - Remote - 1,800 Watts - 12V # PD44FR.

The # PD44FR has an integrated transfer switch that automatically changes from inverter to shore power when you hook up at the campground or to a generator. The fixed-mount remote lets you monitor and control the inverter from inside your RV. It includes a digital display that shows voltage, output power, error codes, and a low battery indicator. It also has a power button to turn the inverter on and off.

I've attached a review video of this unit to offer you some additional information and a video of one of Progressive Dynamic's transfer switches to show you how the internal transfer switch of this unit will function.
