Gain the peace of mind, and quiet that comes with owning the new 12kW generator. Now 60% quieter* and 50% smaller than our old 12kW[1], you don’t have to compromise your homes curb appeal to get the protection of automatic backup power. With its sleek, compact profile, the 12kW[1] Home Standby Generator adds new dimension to “Powering More for Less.”

Perfect for smaller to medium-sized homes, the new 12kW[1] Generator 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).

Why the Symphony® II Power Management System? Well, 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, featured on the 12 kw generator, orchestrates these high-demand appliances with lower-demand items to give you true whole-house power with a smaller, more affordable generator. The package also includes one of the best comprehensive parts and labor warranties in the business - 5 parts and 3 year labor year limited warranty2 your guarantee of quality and performance.
