I found that the same inverter on Amazon at 2000 watt Pure Sine Wave is only $65 more. Although it gets a poor rating. It only has one review of someone that was not happy where the 1500 and 3500 watt in the same brand gets 4.5 stars with more reviews. So, Im thinking the 2000 watt would be worth the extra money especially when I upgrade to 500 watts and 440ah.
I did find out that my .9cf microwave only puts out 900 watts. My 4 cup MR coffee maker only uses 640 watts. The Dish satellite and receiver uses 60 watts and my 40" LED TV used 36 watts...
