Best Standby Generators Buying Guide
Power Capacity and Runtime
Match the generator’s wattage to your home’s essential loads, like 10kW-22kW for average US households covering fridge, lights, and sump pumps. Brands like Generac, Kohler, and Cummins, as highlighted by This Old House, offer scalable options that run 24+ hours on a full tank, ideal for multi-day outages in storm-prone areas.
We recommend sizing up for larger yards or EV charging needs, ensuring value without overkill for typical 2,000-3,000 sq ft homes.
Fuel Type and Efficiency
Choose natural gas or propane models for automatic, cleaner operation without refueling during blackouts. Reputable names like Briggs & Stratton, Honda, and Generac, praised by BobVila.com, provide dual-fuel flexibility for regions with varying fuel access, maximizing runtime on standard home supplies.
This setup suits busy homeowners who want set-it-and-forget-it reliability, especially in rural spots with propane tanks.
Noise Level and Weather Resistance
Look for units under 70dB with sound-attenuating enclosures for neighbor-friendly operation. Consumer Reports favors weatherproof designs from Honeywell, WEN, and Generac that withstand rain, snow, and high winds common in US climates.
Steel frames and corrosion-resistant coatings ensure longevity in humid Southeast or salty coastal environments, protecting your investment year-round.
Automatic Transfer Switch and Smart Features
An ATS kicks in power within seconds of an outage, no manual start needed. Family Handyman recommends WiFi-enabled models from Cummins, Kohler, and Generac for remote monitoring via apps, giving you alerts on fuel and maintenance from anywhere.
Professional installation is key for safety, but these features simplify ownership for non-technical users.
Final Thoughts
For most US homes facing frequent outages, we suggest starting with a mid-range 14kW-22kW model balancing power and cost. The Honeywell 22kW Home Standby Generator stands out for its robust performance and smart connectivity, perfect for keeping your family comfortable through any storm.
