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.

Cover just the basics

Many homeowners choose to cover only a minimum number of rooms during a power outage. Generac's smaller kW units fit these requirements perfectly and are remarkably economical.

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.

#1 selling generator

Standby power for residential applications

Powered by Generac'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 competitor's 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.

User-Friendly Controls

Electronic Controller and user-friendly, trilingual LCD display and controls for programmable diagnostics and information at-a-glance. Sophisticated codes alert you to generator status at all times.

Safe for sensitive electronics

TruePower Technology provides confident operation of sensitive electronics such as heating, cooling, home theaters and computers. Less than 5% total harmonic distortion gives smooth and consistent electrical power quality and performance.

Harsh weather conditions? 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.
