Consider a Automatic Standby Generator
Why Do You Need a Generator?
To keep your home running and your family safe and secure you may wish to consider an automatic standby generator. Even though power outages may only occur a couple of times a year, when it does the inconveniences are real, lack of heat, no lights, no television or radio to keep up with the news about the storms, loosing food in the refrigerator and freezer can add up to hundreds of dollars in loss. Some people have medical equipment that needs power to run. By adding an automatic standby generator that is sized appropriately for your application you can remain in your home safely and comfortably during the outage. Even if you are not at home when the power goes out you risk the potential of water pipes freezing and basements with sump pumps flooding. By adding an automatic standby generator to your home you can avoid all of these things and have peace of mind. The generator restores power to your home in less than 30 seconds after the power goes out and automatically shuts off when utility power is restored. An in home consultation can determine which size generator is right for you, anything from a few circuits for lights and refrigerator to the whole house. Under sizing a generator is as bad as not having one at all and over sizing one is just spending money you don't need to spend. Adding a standby generator will add value to your home and increase saleability should you ever decide to sell.

About the OHVI Engine
The Power Behind The #1 Home Standby Generator
The only engine designed specifically for generator use. Why is this important? Generators are often required to run for hours at a time, day after day. Generac's OHVI engine utilizes the same type of pressurized oil lubrication used to give automobile engines long and trouble free lives. This means a significantly longer life than competitive engines - an unprecedented three to four times longer. That's the reliability you need for the long run times emergency backup can require. Generac's OHVI engine powers all air-cooled and many portable generators.

Cover Just the Basics
Many homeowners choose to cover only a minimum number of rooms during a power outage. Generac's smaller kW units fits these requirements perfectly and are remarkably economical for example, an 8 kW can purchased for less than $2000 plus installation to maintain power for essential needs.
Back up the Whole House
Generac's full line of backup power solutions include, larger generators capable of covering every circuit in any size home for true whole house protection.
More Coverage with Less Generator
Gain up to whole-house coverage through Load Shedding Power Management. If it is unlikely every appliance will be used at the same time, a smaller generator paired with a Generac load shedding switch is a cost effective option.
Standby Power For Residental Applications
Powered by Genera's OHVI engine, these units are built for reliability and long life, with a continuous fuel source from the existing LP or natural gas supply. With standard features competitors don't have, it's easy to see why Generac automatic home standby generators are the number one choice in 24/7 power outage protection.
A Weekly Self-Test That Won't wake the Neighbors
All automatic standby generators perform a weekly self-diagnostic test to validate proper operation. Quieter than the competition, only Generac's patented, programmable Quiet-Test mode kicks in for an ultra-quiet, neighborhood-friendly self-test.
Safe For Sensitive Electronics
TruePower Technology provides confident operation of sensitive electronics; such a heating, cooling, home theaters, and computers. Less than 5% total harmonic distortion gives smooth and consistent electrical power quality and performance.
Harsh Weather Conidtions? Bring It On!
Generac's patented galvanneal steel enclosures with RhinoCoat provide substantial protection from the elements. For added protection, the all-weather aluminum enclosure's corrosion resistance prolongs the life of your generator in salt air coastal communities.
