Buying Guide for Gas Fired Generator Sets
Choosing the right gas fired generator set depends on several important factors to ensure reliable performance and safety for your specific needs.
Power Requirements
Evaluate the total wattage needed for your home or job site. Consider starting surge wattage of heavy-duty appliances like refrigerators, HVAC systems, or power tools. Generators range from around 9,000 watts running to over 14,000 watts surge, so choose one that covers your maximum expected load with some margin.
Fuel Flexibility
Tri-fuel models offer the advantage of running on gasoline, propane, or natural gas. This flexibility is valuable for fuel availability and cost savings. Dual fuel models typically run on gasoline and propane, providing a more limited but still versatile option. Verify what fuels are compatible with each generator.
Starting Method
Look for electric start options for ease of operation during power outages, especially in emergency situations. Remote start is a beneficial feature on higher-end models, allowing generator activation from indoors or a distance, enhancing convenience and safety.
Run Time and Fuel Tank Capacity
Longer runtimes reduce the need for frequent refueling. Larger fuel tanks support extended power supply. Some generators include fuel gauges for easy monitoring. Propane tank run times differ from gasoline but typically offer cleaner burning and storage advantages.
Power Outlets and Compatibility
Check the included power outlets such as standard household plugs, RV outlets, transfer switch ready plugs (like L14-30R or 14-50R). Compatibility with transfer switches allows seamless switching between utility power and generator power.
Safety Features
Important safety features include automatic low oil shutdown to protect the engine, GFCI protected outlets to prevent electrical shocks, and carbon monoxide sensors to detect dangerous gas buildup, shutting off the generator if needed.
Noise Level and Portability
If noise is a concern, inverter generators or models with quieter engine designs might be preferable. Portability features like wheel kits and handles ease transportation for job sites or outdoor use.
Durability and Warranty
Look for generators with robust engines, such as 4-stroke OHV engines with cast iron sleeves, indicating longer life and reliability. Consider the warranty terms offered by manufacturers to ensure support and protection for your investment.
