Buying Guide for Dual Fuel Generators
Power Output and Capacity
Select a generator based on your essential load requirements. Consider peak (starting) watts and running watts to power large appliances or your entire home. Generators range from smaller inverter models around 3000 watts to heavy-duty units exceeding 13,000 watts.
Fuel Type and Runtime
Dual fuel capability offers flexibility between gasoline and propane. Propane burns cleaner and stores longer but may have a shorter runtime per tank compared to gasoline. Evaluate fuel tank sizes and expected run durations based on your typical outage scenarios.
Starting Mechanism and Ease of Use
Electric or remote start systems provide convenience, especially during emergencies, while recoil start serves as a reliable backup. User-friendly controls and indicator displays—like digital VFT readouts—help monitor generator status.
Noise Level
Consider the generator’s noise output if you prioritize quiet operation, particularly for residential or RV use. Inverter generators generally produce less noise compared to traditional models.
Outlets and Compatibility
Check for the types and number of outlets, including GFCI 120V, 240V twist-lock connections, RV hookups, and transfer switch compatibility. This ensures compatibility with your home’s electrical connections and appliances.
Safety Features
Sensors for low oil shutdown and carbon monoxide detection add essential safety during use. Weather-resistant outlet covers and durable construction increase reliability and longevity.
Portability and Build Quality
Wheel kits, handles, and compact design contribute to easier transport. Heavy-duty engines with features like cast iron sleeves improve durability for long-term use.
By evaluating these factors, you can choose a dual fuel generator that best fits your home backup power needs, ensuring safety, reliability, and convenience during power disruptions.
