Our dealer exclusive standby generator line offers the protection you are looking for in a generator system. Starting with our premium level of protection by offering a 6 year parts, labor and travel warranty, the longest in the industry. Also equipped with an oil warmer to help aid in cold weather starting when the temperatures drop below 30 degrees.

Now 60% quieter* and 50% smaller than our old 12kW1, you don’t have to compromise your home’s curb appeal to get the protection of automatic backup power. With its sleek, compact profile, the 12kW1Home Standby Generator adds new dimension to “Powering More for Less.” Perfect for smaller to medium-sized homes, the new 12kW1generator combined with our Symphony® II Power Management System allows you to meet the power needs of your whole house, (including up to two 4-ton air conditioners).
*Based on no load sound power.

Managed Whole House Power

Not all appliances are powered equally. Some, such as your central air conditioner, electric clothes dryer, electric stovetop, oven, or whirlpool tub, require a large amount of power to start up or operate properly.

The Symphony® II Power Management orchestrates these high-demand appliances with lower-demand items to give you true whole-house power with a smaller, more affordable generator.
