While Generac's automatic standby generators are capable of operating continuously during power outage scenarios, these units should be stopped at least once every 24 hours of continuous operation to ensure proper maintenance is provided. Also, please know that the loads required in a house will vary, and are not determined by the square footage of the home, but are determined by the items you deem necessary to run in an outage situation. To properly determine the correct generator for your needs, we recommend working with a certified electrician in your local area. For help locating a certified party near you, please contact us directly at 888-GENERAC (436-3722).
