Buying Guide: What to Consider When Choosing a Home Backup Generator
Power Requirements
Determine your household’s total wattage needs by listing essential appliances and systems you want powered during an outage. Consider surge wattage as starting motors often require more power. Generators range from about 4,000 watts to 28,000 watts and beyond—choose one that can handle your combined load.
Fuel Type and Availability
Generators typically run on gasoline, propane, natural gas, or combinations (dual or tri-fuel). Dual and tri-fuel options offer flexibility if fuel supply is disrupted. Propane and natural gas often burn cleaner and store longer than gasoline but check local availability.
Portability vs. Standby Installation
Portable generators offer flexibility and lower upfront costs but require manual start and connection. Standby generators are permanently installed, start automatically during outages, and connect directly to home electrical systems with transfer switches, offering convenience and safety.
Transfer Switch Compatibility
A transfer switch isolates your generator circuits from utility power, preventing backfeed that can endanger utility workers and damage equipment. Many home backup generators come transfer switch ready or include it as part of the package.
Additional Features
- Remote Monitoring – Enables troubleshooting and performance checks from smartphones or computers.
- Electric or Remote Start – Provides ease over manual recoil starts, especially useful for quick power restoration.
- Run Time and Tank Size – Longer run times reduce refueling frequency during outages.
- Noise Levels – Some models feature quieter engines or noise-reducing enclosures, important in residential neighborhoods.
- Safety Sensors – Features like CO detectors and automatic engine shutdown enhance safe operation.
Durability and Warranty
Look for sturdy construction materials like cast iron engine sleeves and aluminum enclosures. Extended warranties are indicators of manufacturer confidence and provide peace of mind.
Budget and Long-Term Costs
Consider initial cost, fuel efficiency, maintenance expenses, and longevity when comparing models. Sometimes a higher upfront cost reflects better durability and lower operating costs.
