Bests & Worsts Reviews from Amazon

My purpose for buying this microwave oven is probably quite different than most of the people that have posted a review here. I wanted a microwave that I could use with my off grid solar system. At this time my solar system consists of 4 100 watt solar panels, a 40 amp mppt charge control, 4 105 amp hr deep cycle batteries wired in series and a 48 volt 1500 watt pure sine wave inverter. The inverter powers my 4.4 cubic ft compact refrigerator, 32 inch flat screen TV and laptop quite nicely. However an older digital 1100 watt microwave that I tried maxed out the inverter and batteries! Plus my inverter is designed to power down between loads which saves on precious energy. Using a microwave with digital controls would tend to keep the inverter powered up all the time unless it was unplugged after each use. As a Prime member I ordered on a Thursday afternoon and received the microwave on Saturday morning. It arrived double boxed without any damage. Curious as to how it would work I heated room temperature water for a cup of coffee in about 2 minutes. Having read that this size microwave 600 watt won't pop popcorn. I found an "old" microwave bag that I had and set the microwave for 6 minutes. To my surprise the popcorn finished popping in about 4 minutes. I have had better (more tender) popcorn but most all of the kernels popped to good size. I plan to buy a fresh box of a better brand to see if I like that any better. For lunch I decided to microwave a frozen personal pizza that I had purchased when checking out the 1100 watt microwave. I stopped the microwave after about 4 minutes as the cheese seemed to be well melted. To my satisfaction the pizza was quite hot all the way though. I don't have a digital AC watt meter at this time but the LED's on the inverter display around 900 watts when the microwave is in use. The load on my batteries seems quite acceptable and on a sunny day the batteries should soon be fully recharged. With the basic 2 knob controls I don't have to worry about unplugging this microwave between uses. Considering the very limited amount of time I have had to use this microwave. I feel it should be a nice addition to my off grid solar system! Update: I have since checked the wattage while the Westinghouse WCM660W 600 watt microwave oven was in use using an inexpensive AC watt meter. The wattage ranged between 940 and 980 watts in several tests. There doesn't appear to be any surge on start as you would experience with a refrigerator.
