Buying Guide: How to Choose Your Whole-House Generator
What size is right for your home? Start with a load assessment that lists essential circuits (refrigeration, heating, security systems, lights, and outlets). A 10kW system generally covers a modest home, while 22kW or 14kW setups are better for larger households with higher appliance usage.
Which features matter most? Consider fuel type compatibility (natural gas or propane), transfer switch amperage, and whether remote monitoring is essential for you. Cellular connectivity adds convenience but may include ongoing subscription costs. Wi-Fi monitoring offers flexible access from anywhere, while built-in cellular can work even when Wi-Fi is down.
What about installation and safety? A licensed electrician or generator installer should evaluate your electrical service capacity, panel compatibility, and natural gas supply. Outdoor-rated enclosures protect against weather, while aluminum enclosures offer durability. Your local climate may influence enclosure choice and corrosion resistance.
How important is reliability and service? Look for brands with long warranties and established networks for parts and service. Generac is a common choice with broad model variety and dealer availability. Kohler and Honeywell provide strong options for quality power and specific feature sets. Compare total cost of ownership, including potential maintenance contracts and monitoring plans.
