Buying Guide
Choosing a dual fuel generator involves balancing power needs, fuel practicality, and safety features. Start by calculating essential loads: lights, HVAC, refrigeration, and critical electronics. Oversize by about 20-30% to handle startup surges and future needs. Consider how you will refuel and store propane or gasoline, and review run-time expectations based on tank size and load.
Fuel choice shapes performance and practicality. Gasoline is readily available and easiest for many users, but propane stores longer and offers cleaner combustion. If you intend to store fuel for emergencies, propane can be easier to manage. Look for units with a digital display or hour meter to track maintenance and fuel usage over time. Transfer switch readiness simplifies safe, automatic power transfer to your home circuits.
Key safety features should guide selection. CO alarms or shutoffs reduce the risk of carbon monoxide exposure, while automatic low-oil protection helps prevent engine damage. Noise levels matter for daily life and compliance with neighbor guidelines, so check decibel ratings and enclosure design. Finally, evaluate warranty length and dealer support, as high-wattage dual-fuel units are a long-term investment that benefits from solid service networks.
