A standby generator is a backup power system that automatically activates during a power outage. It is typically connected to a home or business's electrical system and can provide electricity to essential appliances and systems, ensuring minimal disruption during blackouts. These generators run on fuel, such as natural gas or propane, and are designed to start within seconds of a power failure. They are often installed outside the building and require professional installation to ensure safety and compliance with local regulations. Regular maintenance is essential for optimal performance and longevity.
