Buying Guide: Key Considerations for Dual Fuel Generators
- Fuel flexibility: Choose a unit that runs well on both gasoline and propane, with a straightforward switching mechanism.
- Power needs: Assess running watts and peak watts to cover essential circuits or whole-house loads. Factor in future expansion.
- Starting method: Electric start offers convenience, while recoil start is simpler and cheaper. Remote start can be a major time-saver during outages.
- Safety features: Look for CO detectors/shutdown, automatic low-oil shutdown, and rubber outlet covers for weather safety.
- Outlets and transfer readiness: Ensure the unit has the necessary outlets (120V/240V, 30A, RV, etc.) and transfer-switch compatibility if you plan to power a home panel.
- Run time and tank capacity: Larger tanks provide longer operation between fills, essential for long outages.
- Portability vs. capacity: Heftier units deliver more power but require more storage space and handling effort.
Frequently Asked Questions
- What does dual fuel mean? It means the generator can run on gasoline or propane, giving you fuel options during outages or when gasoline isn’t readily available.
- Do I need a transfer switch for home backup? For full home backup, a transfer switch or an automatic transfer switch is typically required to safely power selected circuits without backfeeding the grid.
- Is a higher wattage always better? Higher wattage provides more power for more devices, but it also increases size, weight, and cost. Match wattage to your actual needs.
- Is CO safety worth it? Yes. CO detectors help automatically shut down the generator if dangerous carbon monoxide levels are detected, which improves overall safety in enclosed spaces.
- What maintenance is needed? Regular oil changes, air filter checks, spark plug inspections, and proper storage practices help extend life and reliability.
- Which unit is best for RV use? Units with a 30A RV outlet or a dedicated RV receptacle, plus transfer-switch readiness, are ideal for RV setups and temporary power needs.
