Buying Guide For Dual Fuel Home Backup Generators
Choosing the right dual fuel generator involves multiple factors beyond just power output. Below are key considerations for selecting the best generator for home backup power:
Power Output and Capacity
Assess your essential appliances and home systems to determine wattage needs. Dual fuel generators offer a range from 5000 watts for smaller homes or RVs up to 15,000 watts for larger residences. Selecting a generator with some extra capacity ensures it can handle startup surges and future needs.
Fuel Flexibility and Runtime
Dual fuel models typically run on gasoline and propane, while some tri-fuel options add natural gas compatibility. Propane tends to store longer and burns cleaner, but gasoline offers higher power output. Look at fuel tank size and runtime on each fuel type to match your emergency use cases.
Starting Mechanism
Electric start systems, sometimes paired with remote key fobs, provide convenience especially during emergencies. Manual recoil start is reliable but requires physical effort. Having both options combines convenience and redundancy.
Safety Features
Automatic low oil shutdown protects the engine from damage. Carbon monoxide (CO) sensors and automatic shutoff systems enhance safety by preventing carbon monoxide poisoning, an essential feature when using generators indoors or near living spaces.
Outlets and Compatibility
Verify the types and quantity of power outlets, including 120V household outlets, RV-ready outlets (30 amp or 50 amp), and transfer switch ready connections for home wiring. This ensures you can plug in essential appliances and transfer power seamlessly.
Portability and Setup
Generators equipped with wheels, handles, and minimal assembly requirements simplify handling and placement. Heavier units with higher power often include wheel kits. Check whether included accessories like hoses or toolkits support immediate use.
Noise Levels and Brand Reputation
Noise can be a concern near residential areas. While not always specified, look for inverter technologies or sound-rated models if quiet operation matters. Choosing established brands with strong reviews and support ensures reliability and easier maintenance.
