Why should I buy an automatic backup generator instead of a portable generator?
During a utility power outage, an automatic backup generator provides numerous advantages over a portable generator:
- The American Red Cross recommends permanently installed backup generators as a safer way to provide backup power to a home than a portable generator.
- With an automatic backup generator properly installed outside, your home is protected from deadly carbon monoxide poisoning that is a much greater risk with portable generators.
- Running on the home’s natural gas or LP fuel supply, it is less expensive to run than gasoline and does not need to be refilled.
- They start automatically within seconds of a power outage, and eliminate the need to haul a portable generator outside or run extension cords throughout your home.
- They provide protection 24/7, whether you’re home or away, and they turn themselves off when utility power returns, so there is no need to monitor the unit during an outage.
What is an automatic backup generator?
An automatic backup generator is a back up electrical system that operates whether you are home or away. Within seconds of an outage, it automatically supplies power directly to your home’s electrical circuit breaker box. After utility power returns, the generator shuts itself off and waits for the next outage. It operates on natural gas or liquid propane gas and sits outside just like a central air conditioning unit. See our "How It Works" video for more information.
What is the difference between an automatic air-cooled generator and an automatic liquid-cooled generator?
The engines! Air-cooled generators come with engines that use fans to force air across the engine for cooling, while 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 required for the higher power output.
How does the Generac OHVI® engine compare to air cooled engines used in other brands of backup generators?
Unlike other engines, used in backup power generation, Generac OHVI engines are made specifically for generators. They are engineered to run for the long periods of time required during a severe power outage or on a job site, utilizing the same type of pressurized oil lubrication used to give automobile engines long and trouble-free lives.
