Inverter with residential refrigerator

We installed a residential refrigerator two years ago. It is similar to yours but is 10 cubic foot capacity. Using a Kill-O-Watt meter, I measured the power draw when running at 100 watts and the multi-day average draw at 40 watts. Per the Home Depot Energy Guide label for your unit (411 kwh/year) your average draw should be on the order of 47 watts. If your running duty cycle is similar to ours, your running power draw should be around 120 watts. A key consideration is the startup surge drawn by the compressor. The compressor in our unit is labelled by the manufacturer at LRA = 11 amps (or about 1,320 watts, Locked Rotor Amperes). The inverter should be sized to supply this surge, not just the running watts. I selected a 1,500 watt AIMS pure sine wave inverter dedicated to the refrigerator for our application. During our last camping trip, the AIMS stopped working. Since we were at a campground with electric power, I simply unplugged from the inverter and plugged into campground power. A first project this spring will be to replace the inverter.
