Generator Comparison
Generac vs Kohler
Which Generator Is Right for Your Home?
Generac and Kohler are the two most popular home standby generator brands in the United States. Generac holds approximately 75% of the residential market and is known for offering the best value per kilowatt, while Kohler commands a premium for its whisper-quiet operation and commercial-grade engines. Both brands offer reliable automatic backup power with Wi-Fi monitoring, but they differ significantly in price, noise levels, and available power output. Choosing between them depends on your budget, noise sensitivity, and how much power your home requires during an outage.

Our Recommendation
For most homeowners, Generac offers the best balance of price, power, and dealer availability.
