How to Choose Best Propane Generators
Propane generators—often referred to as dual-fuel or tri-fuel units—use Liquefied Petroleum (LP) gas as a primary or secondary power source. They are essential for providing reliable electricity during outages, as propane is a fuel with a nearly indefinite shelf life, unlike gasoline. Choosing the right one is critical because propane models often have lower power output (running watts) than their gasoline counterparts, requiring you to carefully match the generator’s capacity to your actual needs (e.g., refrigerator, well pump, lights). The Best Propane Generators offer a safe, clean-burning, and convenient power solution for both emergencies and off-grid applications.
Power Output (Running Watts)
Power output, or running watts, is the most crucial specification. It tells you the maximum continuous power the generator can produce. You must calculate the combined running watts of all the items you need to power, plus the high surge power required by motor-driven appliances like refrigerators and AC units. Evaluate a portable unit for home backup or a permanent model like a Generac standby generator for whole-house protection.
Fuel Type and Switching
Dual fuel means using gasoline or propane, while tri-fuel adds natural gas. Propane is cleaner, stores indefinitely, and is often more readily available post-disaster, but it provides slightly less power. Assess the ease of switching fuel sources—a simple selector dial is far better than a complex manual changeover process. This flexibility adds security to your emergency plan.
Transfer Switch Readiness and Outlets
For home use, look for generators labeled as “transfer switch ready,” which means they have the correct 30A or 50A outlet (NEMA L14-30R or 14-50R) to connect safely to your home’s electrical panel. This allows you to power hard-wired appliances directly and avoids hazardous extension cords. The number and type of outlets determine what you can plug in simultaneously.
Portability and Noise Level
Generator noise is measured in decibels (dBA). Traditional open-frame models are louder, while inverter generators are significantly quieter (often under 65 dBA) and produce cleaner power, suitable for sensitive electronics. Consider portability, too: large home-backup units (over 200 lbs) require heavy-duty wheels, while camping models (under 60 lbs) prioritize lightweight design.
Safety Features (CO Shutoff)
The most vital safety feature is the integrated Carbon Monoxide (CO) sensor or automatic CO shutoff system. These life-saving sensors detect the presence of dangerous CO gas and automatically turn off the engine before levels become harmful. This is a critical feature that should be mandatory for any generator used in or near residential areas.
Understanding Propane for Backup Power
Propane (LP gas) is an ideal choice for backup power due to its superior storage properties. Unlike gasoline, which begins to degrade in 3–6 months, propane can be stored in tanks for decades without going bad, ensuring your fuel is ready when you need it most. It also burns cleaner, reducing carbon deposits on the engine and extending the generator’s lifespan with less maintenance required. This characteristic is why many prefer it over gasoline for long-term emergency readiness, as a permanently installed tank offers a continuous, hassle-free power supply until utilities are restored.
Additionally, connecting to a large propane tank is far simpler and safer than frequently refilling gasoline cans. Propane is often easier to procure after a major disaster when gas stations may be inoperable. However, users should note that the generator’s maximum running wattage will be slightly lower (about 10% less) when operating on propane compared to gasoline. For optimal safety, always follow manufacturer guidelines and ensure your generator is placed at least 20 feet away from your home’s windows and doors. You can learn more about this fuel source on the propane Wikipedia page.
How to Use Best Propane Generators
Setting up and using your propane generator correctly is essential for safety and optimal performance. Follow these steps for a safe start-up and operation, ensuring your Best Propane Generators are ready for any emergency.
- Preparation and Setup: Roll the generator to a dry, level outdoor location, at least 20 feet from any structures, windows, or doors. Connect the included LPG hose from the generator’s inlet to your propane tank, ensuring all valves are tightly secured. Check oil levels and confirm the generator is off.
- Core Usage & Best Practices: Open the valve on the propane tank. If dual-fuel, set the fuel selector to ‘Propane.’ Turn the key for electric start (or use the recoil pull cord). Engage the choke if the engine is cold. Once running, allow it to warm up for 5 minutes before plugging in appliances, starting with the highest-amperage items first.
- Optimization/Safety/Maintenance: For extended run times, utilize any ‘Eco Mode’ or ‘Low Idle’ feature available, which reduces engine speed and fuel consumption. Monitor the oil level using the dipstick and perform regular oil changes and checks as indicated by the hour meter. Always keep a backup tank of propane, or consider a permanent installation like the whole house generator.
- Troubleshooting & Pro Tips: If the generator fails to start on propane, check for any air pockets in the fuel line (sometimes called “vapor lock”). Ensure the tank is not empty and the regulator is functioning. Never refuel or troubleshoot while the engine is running or hot. Shut down the engine completely before adjusting the propane connection.
Frequently Asked Questions
What is the benefit of a dual-fuel Best Propane Generators model?
The primary benefit is fuel flexibility and security. Propane stores indefinitely and is a cleaner-burning fuel, which is crucial for long-term backup. If gasoline becomes unavailable during a disaster, the ability to switch to propane ensures you can keep your power running.
Are Best Propane Generators safe to use?
Yes, but safety depends entirely on proper usage. They must ONLY be used outdoors, away from windows and vents, due to carbon monoxide risk. Many modern models, like the Generac, now include automatic CO shutoff technology to enhance user safety significantly.
What size propane tank is needed for a typical home backup?
For a typical 7,000-watt portable propane generator running for an extended period, a large 20-pound BBQ tank will only last about 5-8 hours. For real emergency backup, you should look into having multiple 40-pound tanks or, ideally, a large stationary tank installed, similar to a home standby generator.
Can I connect a portable Best Propane Generators unit directly to my home’s electrical panel?
You can, but it requires professional installation of a manual transfer switch and a proper inlet box (usually 30A or 50A). Attempting to back-feed power without a transfer switch is extremely dangerous and illegal, posing a risk of electrocuting utility workers or damaging your home’s electrical system.
Is a portable generator better than a permanent standby model?
It depends on your needs. Portable propane models offer flexibility, lower cost, and can be used on the go. However, a permanent standby generator provides higher power, automatic operation, and runs indefinitely from a connected fuel source, offering true, effortless whole-house protection.
Final Thoughts
Selecting from the Best Propane Generators ultimately comes down to matching its running wattage and fuel type flexibility to your non-negotiable power needs. Prioritize a model that offers a clean, stable output, especially if you plan to run sensitive modern electronics. Always place safety first by choosing a unit with a certified automatic CO shutoff feature and adhering strictly to outdoor-only use guidelines. By focusing on power, safety, and fuel source versatility, you can invest confidently in a reliable backup solution for your home or job site.
For most buyers seeking a powerful, cost-effective portable solution that can handle an entire home’s critical circuits, the Westinghouse 12500 Watt Dual Fuel Generator offers the best balance of output and remote-start convenience. If your priority is maximum fuel flexibility for any disaster scenario, the WEN 14,500-Watt Tri-Fuel Generator (TF1450) is the undisputed choice for its ability to run on gasoline, propane, or natural gas, providing the ultimate in long-term emergency power security.
