Buying Guide: What To Consider When Choosing A Dual Fuel Diesel Generator
Selecting the right dual fuel diesel generator requires evaluating various factors beyond just the wattage output. Here are key elements to consider for your purchase:
Power Output and Capacity
Assess Your Power Needs: Identify the wattage required for your essential appliances and systems. Include surge wattage of motor-driven devices to choose a generator that can handle peak loads efficiently.
Fuel Flexibility and Efficiency
Consider Fuel Options: Dual fuel generators typically run on gasoline and propane, with some models supporting natural gas. Propane offers cleaner burning and longer shelf life, while gasoline may be easier to source. Tri-fuel provides even more versatility.
Fuel Tank Capacity and Runtime: Longer fuel tanks enable extended operation during outages. Check how many hours the generator can run at 50%-75% load on a full tank for practical usage.
Starting Mechanism
Electric Start vs. Recoil: Electric start with remote key fob or push-button increases convenience, especially during emergencies. Some models include recoil backup for manual starting.
Output Connections and Compatibility
Check Outlets: Multiple household outlets with GFCI protection and transfer switch ready ports allow safe connection to your home circuits and RVs. RV-ready plugs add versatility for outdoor applications.
Voltage Options: 120V is standard for home appliances, but 240V may be necessary for larger equipment or transfer switches.
Engine Build and Durability
Engine Size and Construction: Generators with durable engines featuring cast iron sleeves and overhead valve (OHV) design generally offer better longevity and performance.
Maintenance Features: Systems with low oil shutdown and carbon monoxide sensors enhance safety and durability.
Noise Level
Consider Noise Output: If you need a generator for camping, RV use, or residential neighborhoods, models with inverter technology and noise reduction features are recommended.
Portability and Weight
Mobility Matters: Consider if the generator has wheels, handles, and manageable weight for easy transport, especially important for portable or job-site use.
By focusing on these factors, you can select a dual fuel diesel generator tailored to provide efficient, reliable power backup suited to your home or outdoor needs.
