A standby generator is a backup power system that automatically activates during a power outage. It is typically connected to a home's electrical system and can provide electricity to essential appliances and systems, ensuring that daily activities can continue without interruption. These generators run on fuel sources like natural gas or propane and are designed to start up quickly when needed. Standby generators are often installed outside a home or building and are equipped with an automatic transfer switch. This switch detects power loss and signals the generator to start, allowing for a seamless transition to backup power. Regular maintenance is essential to ensure reliability and longevity.
