Generac portable and standby generators are manufactured at the Generac Power Systems, Inc. factory in Whitewater, Wisconsin. Their reputation for reliability is second to none. One reason for this is the Generac OHVI engine.
Air-cooled generators come with engines that use fans to assist engine cooling. Liquid-cooled generators use enclosed radiator systems for cooling, similar to an automobile. Generally, liquid-cooled engines are used on larger KW generators due to the larger engines requirement for higher power output.
Most home emergency generators are equipped with engines that are manufactured primarily for lawn and garden applications. On the other hand, Generac OHVI engines are made specifically for generators. They are engineered to run for long periods of time, which is a huge asset when you are confronted with a severe power outage.
Generac OHVI engines have a significantly longer life than competitive engines – an unprecedented three to four times longer – making them the best investment on the market. In fact, they are designed to provide approximately 3,000 hours of use.
Lawn mower engines have no oil level protection, which means the engine continues to run even when the oil level is low… possibly causing serious damage. The OHVI engine shuts down automatically when the oil level is or overheated oil is detected.
In addition, the OHVI pressurized lubrication system works from start-up to shut-down by pumping oil directly to every critical area. Most competitive models splash oil on moving parts thereby missing critical friction areas.
Generac generators have a full pressure lubrication system to allow for the use of an automotive grade oil filter to remove dirt and carbon solids. This compares with many other engines that have no filter at all and rely only on oil changes to drain out impurities and harmful debris.
Another outstanding feature is Generac’s OHVI X-TorqTM Governor, which is the fastest responding governor available. It maximizes engine performance and virtually eliminates stalling. A slow governor can result in poor, low voltage, potentially damaging the electronics.
The Generac OHVI engine powers all portable generators of the XP SERIES 4000-8000 Watts and the XG SERIES 4000-10000 Watts, as well as the GP7000, GP7000E, GP8000, GP8000E, GP15000E, and GP175000E models.
