What is an automatic standby generator?
An automatic standby 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.
Why should I buy an automatic standby generator instead of a portable generator?
During a utility power outage, an automatic standby generator provides numerous advantages over a portable generator:
The American Red Cross recommends permanently installed standby generators as a safer way to provide backup power to a home than a portable generator.
With an automatic standby 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 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 standby 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.
What's the advantage of an aluminum enclosure?
In addition to its sturdy galvanneal steel enclosure with RhinoCoat, Generac is one of the few companies to offer premium aluminum enclosures for its residential standby generators. Aluminum enclosures are naturally rust and corrosion resistant. For salt air or high humidity conditions, aluminum is highly recommended to ensure decades of worry free service.
Can an automatic standby generator replace utility service?
No...the generator fuel costs would be much more expensive than buying power from the utility company since their cost to produce electricity is divided among thousands of customers.
How do I correctly size a generator for my home?
The most logical way to determine your needs is to envision your home without power. Some outages may be short in duration, while others could last for days or weeks. What would your family miss during an outage?
With the broadest product line available, essential circuit coverage starts with the economically priced Generac CorePower™ Series. Other systems are available to cover virtually any application:
Essential Circuit Coverage - Generac takes the guesswork out of sizing by offering prepackaged Guardian Series generator systems. The generator is paired with a transfer switch containing a predetermined number of circuits based on the generator's kW power rating. Each circuit is directly connected to a matched circuit on the home's main circuit breaker panel, providing electricity to that specific appliance or area of the home. For example, ten circuits are supplied for the 8 kW generator. With this system, you could connect (1) lights and TV in the family room, (2) microwave and lights in the kitchen, (3) refrigerator, (4) power to the bathroom, (5) computer and home office, (6) garage door opener, (7) air conditioner, and (8) furnace.
Managed Whole House Coverage - You can get more coverage with less generator, up to whole house coverage, by pairing a smaller generator with one of Generac's Nexus� load shedding switch options. This creates a managed power solution where non-essential circuits are shed when the generator approaches maximum capacity. They are cycled back on when essential circuits no longer require power, so all circuits receive power at different times.
Complete Whole House Coverage - Easily cover every circuit in your home by pairing one of Generac's larger kW units and the proper transfer switch to provide full coverage. No circuit is ever left uncovered, so every appliance is available every minute.
Do they have to be maintained?
Yes, simple maintenance is required. All generators require periodic oil and filter changes to ensure maximum performance for years of reliable service.
What type of oil should I use?
An SAE rated high detergent oil that meets API Service Class SF requirements for gasoline engines, similar to your car. Refer to your owner's manual for details.
What happens if the generator gets overloaded?
Generac generators are equipped with overload protection. In the rare event of an overload, the generator's circuit breaker will trip, disconnecting the unit from the load. Simply correct the overload and reset the breaker in the generator.
