The title says it all. I don't have specific (try to find current draw for any refrigerator online) but the model I am looking at is a Frigidaire EFR751. My SWAG is running power is between 50W-100W. Of course the issue is STARTING current requirements.

In THEORY, a 1000W inverter should be adequate, but probably not. 1500W ? 2000W? I know that "low frequency" are more tolerant to starting loads.

Suggestions for inverter ? (Don't worry about battery. I just need a ride through of a couple of hours and this is after it is already cold.)
 
I would be looking at a victron phoenix for a single appliance application. Like something you will manually re plug into an inverter and don't need automatic backup. I would be surprised if a 1200 phoenix wouldn't suffice. Maybe less.
 
This alone could probably handle it for 12hrs MINIMUM: Eccoflow River 2 Pro

I haven't done a refrigerator test, but it ran my pellet stove quite well on a test last winter. (I may try it if I get time this weekend with my shop full size 15 year old refrigerator.)

Is the Phoenix model just called the Victron VE now ?
 
1000w is generally plenty for most home fridges. Most have 1500w - 2000w surge performance when needed.
Don't skimp on the DC connection that may limit the surge performance.

I have and recommend Go Power inverters but any of the above are good too. Get sine wave.
 
I have had a xantrax x1200 (1200w) running a appartment sized fridge for a few years. It also runs lights, small power tools and charges milwaukee M18 batteries just fine. I even run a 700w microwave on it and dont even think about what the fridge is doing at the time.
