Power your RV adventures with a Generac generator.

Reliability for the Long Haul

Generac understands the freedom of RVing. Turn on the A/C, microwave, or TV whether you are en route, staying at a campsite, or boondocking in the middle of nowhere. Having access to power at all times is essential to your comfort--in all altitudes and under all conditions. Engineered specifically for the unique needs of recreational vehicles, Generac RV generators start quickly and run quietly, deliver reliable power, and have extra power and surge capacity built-in.

You'll be able to run sensitive electronics--from laptops to HDTVs--with stable power that is optimized by Generac's solid state frequency voltage regulator. A durable, all-steel enclosure with RhinoCoat finish and internal muffler system provide superior noise reduction that meets or exceeds all national park noise standards. An industry standard footprint on all models makes installation easy, and the generator's up-front design means you can conveniently access the air, oil and fuel filters, spark plugs, and other components for routine maintenance and servicing.

Powerful Engine with Plenty of Wattage

This QuietPact generator's three-cylinder, 1131-cc ISM diesel engine offers a speed control that allows it to operate at a constant speed of 1950 RPM under any load (for 8,500 watts of power), eliminating annoying speed changes. Annoying speed changes are eliminated, and noise level unaffected by number of appliances in use (air conditioner, TV, microwave, etc.). And while under typical loads, the generator's constant RPM allows for a much more fuel efficient system when compared to variable speed models.

The full-pressure lubrication system provides better performance, less maintenance, and significantly longer engine life. An enclosed critical grade muffler is mounted inside the unit to prevent injuries while stationary or in transit. Other features include a standard hour meter, main line circuit breaker for overload protection, high-temperature shutdown to prevent damage from overheating, and a 2 amp "trickle charger" that maintains the battery when the generator is in use.

Travel with Confidence

All Generac RV generators are covered by an industry leading 3-year limited transferable warranty. With trained and authorized service locations throughout North America, you can rest assured that needed support is within reach no matter which road you take.
