Inexpensive compressor fridges are notorious for high in-rush startup current requirements. An inverter that "sags" under heavy load may cause the compressor to stall and burn out.
YMMV

That is a good point and good to mention. Rule of thumb for inductive inrush on a compressor motor... 10X the running current just for the fridge startup(some may be slightly higher and "mileage may vary").... then if you have other things you plan to run simultaneously, need to be sure you have it covered.
Having said that, with either appliance (the inverter or fridge), they should have protection built in. In the case of the inverter, if you have other things running and the fridge comes on and exceeds max current due to inrush, the inverter should trip overload and just shut off. Likewise, if the Fridge sees a voltage sag beyond a certain threshold,a relay should drop out to protect the compressor. Most appliances are "smart" in this way due to frequent power sags and etc. on the grid. It is common where I live in heat of summer with the heavy home cooling load across the state.
I'd personally just get a 1500W Pure sine inverter since the standby current will be nearly the same. You will have plenty for the fridge and can then run a few other "heavy" draw devices like a blender, small microwave, or etc. as needs demand without getting into that 80% continuous load keepout area. Just be cognizant of what is on and that the fridge is there and may need to start up.
