Buying Guide for Backup Electric Generators
Fuel Types and Flexibility
Choosing between gasoline, propane, natural gas, or tri-fuel generators depends on availability and storage convenience. Dual fuel generators provide flexibility to switch between gas and propane, ensuring fuel is accessible during emergencies. Tri-fuel models add natural gas, often useful if connected to a home supply.
Power Output Needs
Evaluate your total power needs by listing essential appliances and devices. Running watts and surge watts determine if a generator can start and sustain your equipment. Larger homes require higher peak wattage (10,000+ watts) for whole-house backup, while smaller setups can work with inverter generators of 5,000–8,000 watts.
Run Time and Fuel Efficiency
Longer run times reduce refueling during outages. Generators with bigger fuel tanks or efficient engines provide longer continuous power. Eco-mode features help save fuel by adjusting engine speed to demand.
Portability and Noise Levels
Consider generator weight and dimensions if you plan frequent moves or RV use. Inverter generators usually offer quieter operation, measured in decibels (dBA), suitable for noise-sensitive environments like campsites or neighborhoods.
Startup Methods and Safety Features
Remote electric start adds convenience compared to manual recoil start, especially useful during emergencies. Safety features like automatic low oil shutdown and CO detectors help protect the generator and users from damage or hazards.
Outlets and Compatibility
Check for suitable outlets to connect home circuits, RVs, or sensitive electronics. Transfer switch ready outlets simplify integration with home panels. Pure sine wave output is important for sensitive electronics to avoid damage.
Durability and Warranty
Invest in models with robust engine construction, such as cast iron sleeve cylinders, for longer lifespan. Additionally, manufacturer warranties and customer support are key for peace of mind.
