Buying Guide For Propane Backup Generators
Power Output Needs
Assess how much power your essential appliances and devices require during an outage. Generators listed range from about 4,500 to 13,000+ running watts. Larger homes or multiple system loads will demand generators in the 10,000+ watt range.
Fuel Flexibility
Dual fuel (gasoline and propane) and tri-fuel (gasoline, propane, and natural gas) options increase fuel availability during emergencies. Propane is cleaner and has better shelf life than gasoline, while tri-fuel models offer maximum convenience.
Start Mechanism
Electric or remote start models provide ease of use, especially during stressful blackout conditions. Recoil start acts as a manual backup but can be harder to operate.
Run Time and Fuel Capacity
Longer runtime reduces the need for frequent refueling. Look for large fuel tanks and efficient engines. Some generators provide up to 19 hours runtime at partial load.
Outlets and Transfer Switch Compatibility
Ensure the generator has enough and the appropriate types of outlets for your needs, including GFCI protection and transfer switch readiness. RV-ready plugs are useful for recreational vehicle owners.
Safety Features
Carbon monoxide (CO) shutdown sensors and automatic low oil shutoffs provide critical protection and peace of mind when operating the unit indoors or near occupied spaces.
Noise Level
If noise is a concern, inverter generators or models advertised as “quiet” offer lower decibel output while maintaining power delivery.
