my microwave draws 1565 watts. 1500 is not going to cut it for me.
wow, is that a comercial restuarant model? I havent seen one rated over 1100 and that being one of the biggest ones, most I see are 900 to 1000.
Microwaves have two spec's on "watts". the advertized one, which is usually the OUTPUT power, then on the back plate the actual power draw from the line. The first is commonly in the 1000W range, the second is usually in the 1300-1500 watt range. At least in the U.S. if current draw exceeds around 12A they need to be equipped with a 20A plug rather than the common 15A plug. That pretty much limits them to 1500 or so watts actual power draw.
Then there is the power draw and VA. Since they are not a resistive device and usually no power factor correction, the current draw (which inveters care about) will usually be higher than derived from assuming a resistive load.
