How Does Backup Power Work?

By: Aneta Podgorska, Marketing Manager, Kinsley Power Systems – an authorized Kohler Generators Distributor


Have you toyed with the idea of purchasing a generator for your home but don’t know how one works or even what to look for? The process of purchasing a generator is fairly straightforward and knowing how backup power works will make your decision that much easier.

aaa39205To start off, your home receives electricity from your local utility company.  When electricity is lost due to a storm or something else, the power is interrupted and you’re left in the dark. The standby generator’s automatic transfer switch senses when utility power is unavailable and sends notice to the generator. The generator starts up automatically to restore your home’s power within seconds and begins to generate electricity. The generator will continue to produce electricity until the automatic transfer switch senses that stable power has returned, at which point the transfer switch will switch back to the utility for power and your generator will shut down.

The electrical draw of some homes may also require a load control module in the system in order to prevent overloading your generator. The load control module directs power to your appliances based on the priority you gave them when your generator was installed. That’s how backup power works!

Home standby generators are extremely convenient during power outages because they’re fully automated; it’s designed to automatically kick in – if you’re home or away – during a power outage. If you’d like to receive updates about your generator’s operation, you can choose to equip your backup power system with Kohler’s OnCue Generator Management System. The OnCue Generator Management System can send text messages or e-mails to notify you if your loses power, if your generator is due for maintenance, and when your generator is running or shutting off. With this system and an internet connection, you can keep an eye on your generator from anywhere.


In addition to being convenient, home standby generators are also extremely reliable and safe. They generally have a regularexercise schedule where they turn on every month and run for 20 minutes to make sure that the unit remains ready to perform when needed. They are installed by professional electrical contractors and generator dealers who make sure to size the generator to handle your appliances correctly and prewire connections properly.
