It is said the sine wave inverters are better the modified inverters. However, I have been powering my cabin's refer, lights, computers and furnace for 5 years with a modified sine wave inverter (Xantrex 3kw) and have no problems. I guess because theory is better than real life to some. Also, some refrigerators require 8-10 amps at 120vac(100+amp @ 12v) and I wonder how the life of the vehicle alternator is affected by this intermittent power draw from the batteries while driving.
Good afternoon "justme". Yes in many cases modified sine wave inverters do a fine job, however with a 120 volt AC motor on many residential fridges (not all) a sine wave inverter will do a better job.
Also you may have slipped a decimal point on the power usage of a modern compressor type fridge. Although there was a time when they did indeed draw that much power, a modern residential fridge will draw around 1 amp of power when running and actually only runs about 20 minutes out of the hour.
