Buying Guide: Choosing the Best Dual Fuel Standby Generator
Selecting the right dual fuel standby generator requires balancing power needs, fuel options, portability, and safety features. Consider the following key factors:
Power Output and Capacity
Assess the wattage needed to power critical appliances and your entire home if desired. Generators like the DuroMax XP13000 series offer over 13,000 watts, suitable for full-home backup. Smaller units like the WEN 3600-Watt serve well for RVs or partial home use. Match generator capacity with your essential electric load for uninterrupted power.
Fuel Flexibility: Gasoline vs. Propane
Dual fuel generators provide versatility using gasoline and propane, enabling longer runtimes and alternative fuel availability. Propane is cleaner-burning and lasts longer in storage, reducing maintenance. Gasoline is often more readily available and may deliver slightly higher power output. Some models like the AIVOLT 8000W feature automatic fuel switching for convenience.
Start Mechanism and Controls
Electric start options and remote key fobs, as featured in Westinghouse models, add user-friendly operation, especially during emergencies. Digital displays like the VFT gauge inform you about voltage, frequency, and runtime, improving monitoring ease.
Noise Level and Portability
If you plan to use your generator in noise-sensitive environments or for recreational purposes, prioritize quiet inverter models such as WEN’s dual fuel inverters. Lightweight units with wheels and handles increase portability and storage convenience.
Safety Features
Ensure the generator includes carbon monoxide (CO) detectors and automatic CO shutoff sensors to protect from harmful fumes. Low oil shutdown is also critical for preventing engine damage during prolonged use. Transfer switch readiness facilitates safer and straightforward connection to home electrical systems.
Runtime and Fuel Tank Size
Long runtimes reduce refueling frequency during outages. Fuel tank capacity and efficiency vary widely. Larger tanks, like on the Westinghouse 12500, can run up to 12 hours or longer, while propane usage times also depend on tank size. Consider your typical outage duration and convenience of refills.
By carefully evaluating these aspects, homeowners can select a dual fuel standby generator that fits their power demands, budget, and safety priorities, ensuring reliable power whenever needed.
