Generac Standby Generators

For Home and Small Business

Our lives depend on power.

Power outages can happen at any time, without warning, and can leave you powerless for days. Without power, you will not have access to, or have the ability to use:

Generac is the #1 name in standby power. Since 1959, Generac has focused on power generation, offering more generator solutions than any other manufacturer, making it the number one choice in residential standby power for peace of mind and the power to live.

A chart shows weather-related outages from 2018-2020, with Strong Storms accounting for 58.1%, Snow/Ice Storms 13.8%, High Winds 13.5%, Hurricanes/Tropical Storms 11.4%, Planned Outages 2.4%, and Other 0.8%.

How a home standby generator works:

  1. Your power goes out due to storms, grid failure, or other causes.
  2. Your Generac generator detects the outage and automatically turns on within seconds.
  3. When utility power is restored, your Generac transfer switch senses this and tells the generator to turn off, switching your home back to utility power. The generator returns to standby mode.

Choose the right size home standby generator for your situation.

Sizing your generator according to your needs, rather than just your home's square footage, prevents overspending or inadequate coverage. Generac offers solutions for different needs:

LEVEL 1: ESSENTIAL CIRCUIT COVERAGE

This option covers only your most important circuits, such as lights, furnace, water heater, refrigerator/freezer, and sump pump, providing a simple and economical solution.

LEVEL 2: MANAGED WHOLE HOUSE

This option provides whole-house coverage through smart power management. It's ideal if you don't turn on every appliance simultaneously, using a smaller generator paired with a power-management switch to manage power requirements.

LEVEL 3: COMPLETE WHOLE HOUSE

Generac's full line of backup power generators includes larger units capable of covering every circuit in any size home for complete peace of mind, ensuring everything stays on during an outage.

Home Standby Generators

Never worry about losing power again. Generac generators turn on automatically in the event of any power loss to restore power to your home within seconds, protecting your family and property.

IDEAL INDUSTRIES/APPLICATIONS:

Nothing is built like a Generac.

Generac generators are engineered for continuous use, providing reliability for demanding situations. Key features include:

Mobile Link™

Generator Connectivity

Monitor the status of your Generac generator from anywhere in the world with Mobile Link™ Connectivity, standard on all Generac home standby generators. Mobile Link connects to your home's Wi-Fi, allowing you to receive information like operating status and maintenance alerts via your smartphone, tablet, or PC.

How does it work?

  1. Your generator experiences a change in status (running, fault, or maintenance alert).
  2. Mobile Link sends you a real-time notification to your app, email, or text.
  3. For ultimate peace of mind, you can authorize your preferred service dealer to receive generator alerts to proactively address any issues.

Key Features
