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.
