Standby Generators Generators
Standby (home backup) generators are permanently installed units that connect directly to your home's electrical panel and start automatically within seconds of a power outage. They run on natural gas or propane, so there's no fuel to store and no manual starting — the power just comes back on. Sizes typically range from 7,500W to 22,000W and can power everything from a few essential circuits to a fully loaded home including central AC. Installation requires a licensed electrician, a concrete pad, and a transfer switch, so total cost is significantly higher than a portable generator. But for anyone who depends on uninterrupted power — medical devices, home offices, freezers, well pumps, or home businesses — a standby generator is the most reliable and convenient option.
