In Stock Automatic Home Standby Generators Ship from Our Warehouses in Days

An Automatic Home Standby Generator senses a power outage the moment it happens. The generator engine starts and seconds later, the automatic transfer switch isolates the home from the utility supply and switches the house to the generator. Power is restored, usually within seconds after the outage hits. Later, after the utility restores power, the transfer switch moves the home back to utility power and begins to shut down the generator. An Automatic Home Standby Generator works in any weather. It won’t matter if you’re home, on vacation, or at work. The automatic generator keeps your home and family supplies with the critical power it needs.

Kohler Power Home Generators

Kohler Generators have delivered energy solutions around the world sine 1920. The revolutionary Kohler Power & Light generator system for rural homes and farms brought power to the countryside before electricity was available. The automatic generator turned itself on and off as power was needed. That same spirit of innovation today allows Kohler Generators to keep the power on when you need it most and continue even when the outage extends beyond a few days to weeks or even a month or longer.
