Our Most Popular Generac Generators

Not sure which generator is right for your home? You’re not alone. Here’s a quick breakdown to help you choose between two of the most popular whole-home options:

Guardian 22kW Generator by Generac

22kW: Solid choice for most medium to large homes. Keeps the essentials running—like your fridge, lights, sump pump, and even your central AC.

If you want to stay comfortable and connected during an outage without powering every single appliance.

Guardian 24kW Generator by Generac

24kW: Perfect for larger homes or families with higher energy needs. Think multiple HVAC systems, electric ovens, laundry machines, and more.

If you want your home to run almost like normal during an outage, this is the way to go.
