Fuel Options Guide

The tri-fuel capability is this generator's defining advantage, offering three distinct power and runtime scenarios. On gasoline, you get maximum output with 13,000 surge watts and 10,500 running watts, plus the longest runtime at 7.7 hours on half load with the 7.1-gallon tank. Gasoline is ideal for emergency backup and maximum power demands.

Propane offers a middle-ground option with 11,250 surge watts and 9,000 running watts. Using the included LPG quick-connect adapter and six-foot hose, a standard 20-pound propane tank provides approximately 3 hours of half-load runtime. Propane is cleaner burning, stores longer without degradation, and is widely available at hardware stores and gas stations.

Natural gas provides the longest-term solution for stationary installations, delivering 10,000 surge watts and 8,000 running watts. While runtime depends on your gas line pressure and flow rate, natural gas offers unlimited fuel supply when connected to your home or facility's gas line. The NG hose is sold separately, but this option eliminates fuel storage concerns entirely.

Choosing Your Natural Gas Generator

Power Output and Runtime

Your first consideration should be wattage. Calculate the combined starting and running watts of the essential appliances you need to power, like refrigerators, furnaces, and well pumps. The models reviewed here range from robust 10,500-watt units to powerhouse 18,000-watt generators capable of backing up a larger home. Remember, a generator’s output on natural gas is typically 10-20% lower than on gasoline, so always check the natural gas-specific wattage ratings.

Runtime is equally crucial for weathering long storms. Look for units with large fuel tanks and efficient engines that can deliver many hours of power at 25% or 50% load. This ensures you aren’t refueling in the middle of the night. Balancing high power with long runtime will give you the most reliable backup solution.

Tri-Fuel Flexibility

The ability to run on gasoline, propane, and natural gas is a game-changer. A tri-fuel generator offers ultimate adaptability. You can connect it to your home’s natural gas line for indefinite, convenient fuel during extended outages. For portable use or if your natural gas service is interrupted, you can easily switch to propane tanks or gasoline. This flexibility is a core advantage of modern tri fuel generators.

When comparing, verify what accessories are included. Some generators come with the necessary hoses and regulators for natural gas and propane right in the box, while others may require separate purchases. Having everything you need from the start simplifies setup when you need power most.

Safety and Convenience Features

Safety should never be compromised. Carbon monoxide (CO) protection is non-negotiable. Many models now feature CO Sentry or CO Shield technology that automatically shuts down the unit if dangerous levels are detected. Also, look for a low Total Harmonic Distortion (THD), preferably under 3%, which indicates clean, stable power safe for sensitive electronics like laptops and medical devices.

Convenience features dramatically improve the user experience. Electric start with a remote key fob allows you to start the generator from the comfort of your home. A clear digital display that shows voltage, frequency, and runtime helps you monitor performance. For more information on the broader category, visit our fuel types guide.

Portability and Outlet Configuration

Even home backup generators need to be moved. Check the weight and whether the unit includes heavy-duty wheels and a telescoping handle. A design that one person can maneuver from storage to its operating location is highly valuable. The outlet panel is your connection point. Ensure it has the right outlets for your needs, including 120V household plugs, a 240V outlet for large appliances, and often a 30A or 50A outlet for direct connection to a home transfer switch or a large RV.

If you anticipate needing even more power in the future, consider a model with parallel capability. This allows you to connect a second identical generator to double your available wattage. You can explore compatible tri fuel generator parallel kits for this purpose. Also, ensure you have the correct natural gas hose for a safe and proper connection to your fuel source.
