The Generac 5500 is engineered around a robust 4-stroke overhead valve (OHV) engine designed for longevity and optimal thermal efficiency.

To avoid the "carburetor death" mentioned above, follow this strict schedule:

Necessary for connecting to a manual transfer switch or powering heavy-duty equipment.

Before diving into specific models, it's helpful to understand what 5,500 watts can actually power. A 5,500-watt generator can comfortably run a refrigerator (600–800 watts), a sump pump (750–1,500 watts), several light circuits (500+ watts), a TV, and a laptop simultaneously. It can also handle the start-up surge of a large power tool or a deep-well pump, thanks to its starting wattage capability of around 6,800 watts. At this power level, the primary competition often comes from the premium Honda EU7000iS, which has a similar 5,500-watt running output but is an inverter model that produces extremely clean power for sensitive electronics.

While the base GP5500 uses a pull-cord, the GP5500E includes an electric start (battery included) for easier operation in cold weather.
