Generac Power Systems 5981 Details and Specifications

Generac Portable GP Series GP1800

Power the fun stuff or cover an emergency with a GP Series portable generator. Affordable reliability and features not usually found on basic portable models make these a favorite for home use, camping, job sites or outdoor events.

Reliability From the Start
Because of Generac’s focus on power generation, we know how to design an engine that can stand up to the long hours of continuous use generators can be required to run. Cast iron cylinders add longevity, not found on every portable generator engine.

Easily Accessible Controls
A portable generator needs to be ready for use at all times. Generac added a convenient fuel gauge providing at-a-glance fuel monitoring. Many portable models have controls located in inconvenient locations and are difficult to access quickly, especially in the dark. We gave control placement careful consideration, with comprehensive control sets conveniently located for easy access.

Framed for Durability
The hardened steel frame gives our portable generator cradles added strength.

Emissions: EPA/49 State-not for sale to California/CSA-Canada

Includes: Product Literature and SAE 30 Oil
