 +In between those extremes would be rice cookers (~300w constant) and the 3qt Instant Pots (~700w intermittent after pressurization).  
  
 +If one //already has a high-power system for other reasons// it makes more sense to cook with big appliances. It may make less sense to **build** a high-power system to run big cooking appliances. 
  
    
 +===== gotchas =====
  
 +  * microwaves are //rated on cooking power//, not on the power demanded from the system. A "700w" microwave will pull ~1,000w, or ~1,200w after inverter losses.  See the power label for actual demand specs. 
 +  * motorized appliances may have motor start-up demands several times higher than their label wattage
