Product Description
Amazon.com Product Description
Engineered for high performance, the professional-grade Generac XG4000 portable gas-powered generator (model 5778) is ideal for both residential and light commercial applications, providing a reliable 4,000-watt power supply wherever you need it and a maximum power output of 4,500 watts. The XG Series employs the Generac OHVI engine, which has a significantly longer life than competitive engines--up to an unprecedented three to four times longer
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 Engine
The 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 Appliances
The 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 appliances.
This generator is backed by a two-year limited residential warranty (one-year warranty for commercial applications).

Sooooooo Happy!!!!!!,

This review is from: Generac 5778 XG4000 4,500 Watt 220cc OHV Gas Powered Portable Generator With Wheel Kit (Lawn & Patio)
First of all I would like to say that I love this Generator. I bought mine from a local dealer, after reading about this new model from a popular mechanics article and award, but I think my review may be useful to others here. The setup of the generator is very easy and only took me two minutes. Generac includes your first maintenance kit with the generator (this comes in handy, I will explain later.) I got my generator about a two weeks before Wisconsin (where I live) got hit with a huge blizzard 24" of snow and 40mph winds with -5 F temps. We lost power for almost 24 hours - my wife, who was very annoyed that I bought this unit just before the holidays, changed her tune greatly when our house was the only one on the block with heat and christmas lights running. The Generator performed great the entire time. Since Generac includes the maintenance kit I didn't have to run aroud trying to figure out where to buy the oil filter as the unit needs to have oil and filter changed after the first 30 hours (break in period.)
Now to the features, this model surges to 5000 watts and is very compact and sturdy. The best feature is the built in power meter that allows you to know how loaded the generator is without having to add up the watts. Also, the power quality is very good with this unit and I had no problem running my computer or LCD tv throughout the storm. The noise level, which I expected to be very loud, was not bad at all. I had no problem standing next to the unit while talking to all my neighbors about why I still had power. I am not too concerned about reliability because I bought a Generac because my father has had an older model portable for 13 years and my Uncle has had the same Generac Portable for almost 30!! Also, I have a Pressure washer with a Generac engine on it for 12 years and have never had a problem (lots of use too.) Plus, the unit comes with a two year warranty

Works well & appears to be built to last,
Amazon Verified Purchase(What's this?)
This review is from: Generac 5778 XG4000 4,500 Watt 220cc OHV Gas Powered Portable Generator With Wheel Kit (Lawn & Patio)
Pros:
Sturdy (appears to be built to last), relatively compact to store, easy to move around, relatively quiet (see sound level measurements below), delivers above rated continuous power, engine starts right up, built-in power meter is handy, hour meter, GFI breakers, engine oil & extra air filter included. The price included the shipping and the shipping via freight was straight-forward. Cons: Instructions say that the unit arrives with no engine oil; however when I added less than 1/2 of a quart of oil it overflowed from the engine. Engine occasionally backfires after it is shut down. I have not used this unit too much yet, but did try to bring it up to max continuous load with 3 hair dryers advertised at 1200 W, 1500 W, & 1600 W. Could definitely hear the engine strain a little as the load was increased, but it handled the full load just fine. The noise from the generator was somewhat quieter than a small push mower. The sound pressure was measured as follows: 3' away: 88 dBA 12' away: 78 dBA The sound level changed very little as the generator load was changed.

Nice Generator,

This review is from: Generac 5778 XG4000 4,500 Watt 220cc OHV Gas Powered Portable Generator With Wheel Kit (Lawn & Patio)
This is a great generator. I wanted a quality, compact and "Made in the USA" generator. This one is high
quality and very compact for it's power. Not too loud either. It fired right up on first try and it ran smooth. Can't go wrong with this gen.
