Standby Generators

A permanently installed Generac home backup generator automatically protects your home, running on natural gas or liquid propane (LP) and sitting outside just like a central air conditioning unit. It delivers power directly to your home’s electrical system, either for the entire home or just the most essential items. Now with FREE Mobile Link™, you can monitor your generator’s status from a smartphone, tablet, or computer anywhere in the world. Generac’s automatic operation means you don’t need to be home to start or stop your generator, and with no refueling necessary, it runs on your existing fuel supply.



Generac is the #1 selling brand of home backup generators, and the company that created the home standby generator category. Power is delivered safely to your home’s electrical panel, so you’ll never have to rely on extension cords again. With 24/7/365 customer support from our Wisconsin headquarters, and Mobile Link™ providing real-time operating status and maintenance alerts, you can have peace of mind knowing you’re taken care of before the next power outage.

Portable Generators

Many people first encounter portable generators during a power outage. Generac portable generators keep essential items like lights, refrigerators, freezers, sump pumps, space heaters, and window air conditioners running, minimizing disruption and helping you maintain your lifestyle.



Generac portable generators aren’t just for emergencies. They also provide the power to work and play. Bring one to remote corners of your property for home improvement projects without relying on long extension cords, or use portable power when utility power is turned off for major renovations. They’re also perfect for recreation, from tailgate parties to camping trips, powering kitchen appliances, charging electronics, and keeping entertainment running, so you can enjoy all the comforts of home wherever you go.
