OHVI engine provides a significantly longer lifespan.
Its compact design, smaller footprint, semi-solid, rally-style wheels and fold-down locking handles make this XG Series generator easier to transport. Additionally, its durable construction with oversized full-wrap frame tubing and impact resistant corners minimizes damage from rough handling. And all XG Series generators come with covered outlets for added protection from the environment and rugged working conditions, plus an hour meter to help track maintenance requirements.
Note for California residents: This model is not CARB-compliant. Units sold to California must be CARB-compliant.
Powerful, Long-Lasting OHVI EngineThe Generac OHVI (Overhead Valve Industrial) engine is the only engine designed specifically for generator use. Generators are often required to run for hours at a time, or even day after day. Engines adapted from other applications can overheat and may have shorter lifespans. It offers advanced heat reduction technology such as plateau-honed cylinders that lessen break-in time, plasma moly ring seals that help to keep excess oil out of the cylinder, and graphite piston inserts that provide a smoother surface for the piston to move against--all helping to contribute to a significantly longer engine life.
Maintenance costs are reduced with a spin-on automotive-style oil filter that's larger than a standard filter, catching more particles so oil stays cleaner for a longer amount of time. Service intervals are up to twice as long as competitive engines, approximately 2 years or 200 hours of operation.
Plenty of Wattage to Run a Full Range of AppliancesThe Generac XG4000 supplies 3,600 output watts and 4,500 maximum watts (for start-up of devices). It has an A/C voltage of 120/240 and a frequency of 60 hertz.

For unexpected blackouts, this is enough wattage to run home appliances such as security systems, computers, and electric range tops. For construction and landscaping applications, it's enough to support devices such as trimmers, belt sanders, and circular saws. And for camping and outdoor events, it can run portable stereos, outdoor lights, and electric grills.
(Note: All appliances should be checked for actual wattage ratings.)
This generator's sturdy, 4.5-gallon steel tank ensures a full 13 hours of operation at a 50-percent load, letting you relax for hours of use. You can monitor fuel levels at a glance with the tank's built-in fuel gauge, while the unique lighted Power Bar displays available wattage. Its 120-volt outlets are circuit-breaker protected, guarding against power overloads and allowing the generator to smoothly send power to your
