Portable Generator, 8000W | Electric Start with COsense | 49ST/CSA

Generac’s GP8000E offers many benefits that make this model a favorite for emergency power or recreational use. PowerRush™ Advanced Technology delivers over 30% more starting capacity* (*increase electrical current upon demand above rated output when starting electric motors), and the electric start makes the GP8000E easy to use (battery included). You’ll always be prepared with the plug-in battery jack that keeps the battery charged and ready for unexpected outages. The long-lasting OHV engine and large-capacity steel fuel tank with fuel gauge provide increased durability and up to an 11-hour runtime at 50% load. Rough or rugged environments will not be an issue thanks to the covered outlets for added protection, heavy-duty wheels that will never go flat, and a fold-down handle that will enable you to easily transport your generator to any location. The low-oil feature will automatically shut down the generator, preventing damage to the unit, while the hardened 1.25-in. steel-tube cradle increases strength and resilience. And with the regular maintenance alerts provided by your hour meter, you’ll never be caught off guard.
