Guess I got lucky! My parents got me one 2 years ago along with their 45 watt solar kit. Both still working fine. The inverter is the 1200/3200 model, and I have the thermostat from the fridge hooked into the On-Off switch. So, it automatically comes on when the fridge needs to. I got lucky there too, my fridge starts easy on that inverter, but won't on a couple 1000 watt ones. This is even with the inverter running, and then plugging in the fridge!
