I have found that I can't run my 900 watt microwave with one generator unless I turn off the main breaker on the convertor. I have a 2000 watt generator, but that's the surge capacity, not the running capacity. 2000 watt generators only produce 1600 or 1700 watts continuously, with mine rated at 1600 watts. If you don't need to run A/C, I'd go with a 2200 or 2500 watt generator at the very least. There are some that weigh the same as a 2000 watt unit. The 3000-35000 watt units are significantly heavier, usually around 100 lbs, give or take a few lbs.
