The choice of an inverter is somewhat problematical. We have a Kitchen Aid 18 cu ft French door household fridge, and run it on a dedicated inverter. The refrigerator uses a conventional start setup with capacitors, and not the printed circuit board start setup. Accordingly, we run a Tripp Lite PV 1250 FC modified sine wave inverter. The surge ability on this unit is rated to surge to 1875Watts for up to an hour and 2500Watts for 10 seconds. This inverter has run my Kitchen Aid, a 16 cu ft chest freezer, and a 3 1/2 cu ft basement freezer, all at the same time and full of fish on the way down from Alaska this summer. When I made a mistake and caused all three units to start at the same time, we only saw a 90% load indicating on our monitor panel.
The PV1250 is a top notch MSW inverter which IS designed from the ground up to not only run inductive motor loads but to be able to START them.
It is a heavy duty inverter and uses an old school tried and true 60hz transformer which easily handles inductive loads. Cheaper more modern inverters skip the 60hz transformer in favor of cheaper high frequency chopper transformers which are smaller, lighter weight but simply do not have much reserve for the startup surges.
I have been using my PV1250 now for 6 camping seasons and so far no problems with the fridge running on it.
