Buying Guide for Gas and Propane Generators
Choosing the best gas and propane generator involves evaluating several critical factors to ensure it meets your power needs and usage scenarios.
Power Output and Surge Watts
Assess your total wattage needs, including surge watts required for starting heavy appliances. Generators listed here range from approximately 4500 to 14500 peak watts, suitable for everything from essential home backup to powering large homes.
Fuel Flexibility
Dual fuel models run on both gasoline and propane, while tri-fuel generators add natural gas compatibility. Dual fuel options are more common and provide convenience in fuel availability and storage. Tri-fuel offers additional versatility, especially if you have natural gas access.
Run Time and Fuel Tank Size
Longer run times reduce the need to refuel frequently during outages. Larger tanks on models like Westinghouse (up to 9.5 gallons) enable over 12-19 hours of continuous use. Consider your typical usage duration and fuel storage capacity.
Starting Mechanism
Remote electric start with key fobs adds ease of use, especially in emergencies, compared to manual recoil start. Most premium models feature electric start, and some include recoil as backup.
Safety Features
Look for generators with automatic low oil shutdown to prevent engine damage, carbon monoxide sensors to detect dangerous emissions, and GFCI outlets or rubber covers for electrical safety.
Portability and Weight
Generators vary in size and weight, with some including wheel kits and handles for easier movement. Consider your storage space and necessity for mobility.
Transfer Switch Compatibility
For seamless home integration, generators transfer switch ready simplify connecting to your home electrical system, allowing safe powering of circuits without backfeed risks.
Noise Level
Sound output can be an important factor, especially for residential areas. Models like the Westinghouse inverter generator operate quietly, while larger power-focused models might be louder.
