Dual Fuel Generators: The Basics

Before we start reviewing the best dual fuel generators of 2021, let us first explain the basics of dual fuel generator technology. Dual fuel generators (sometimes called ‘hybrid generators’) are generators that use two fuel sources instead of one. These fuel sources include gasoline, propane, and/ or natural gas.

Why Two Fuels Are Better Than One

Using multiple fuel sources in your generator allows you to run it for longer, as you can switch fuel sources when one runs out. There are also other advantages to investing in a dual fuel generator over a regular generator, as:

  • You can use lower-cost fuels like propane.
  • Dual fuel generators are more versatile than regular generators.
  • You can run your generator on fuels with a longer shelf life.
  • Dual fuel generators are often quieter than regular generators.

How Dual Fuel Generators Work

Like regular generators, dual fuel generators take mechanical energy from their energy source (i.e., propane, gasoline, diesel, or natural gas) and force it through an external electric circuit. This flow of electricity charges the generator, which is then able to power your home, garage, or campsite. Generators are often compared to water pumps, as they do not “create” electricity but channel it. 

While each generator manufacturer uses a slightly different mechanical system, generators usually have the following components:

  • Engine = which takes mechanical energy from the fuel source and pumps it into the alternator. 
  • Alternator = which takes mechanical energy and outputs electricity. 
  • Fuel Systems/ Tanks = which stores fuel prior to use by the engine.
  • Voltage Regulator = which controls the voltage of the electricity output by the generator. 
  • Cooling and Exhaust Systems = which draw into the generator to ensure a medium temperature is maintained. 
  • Lubrication System = which stores and pumps oil into the engine parts. This prevents them from seizing or becoming damaged. If you’d like to learn more about the role of oil, check out our ‘Best Oil Filters Guide.’
  • Battery Charger = which takes electricity from the alternator and charges the generator’s battery. 
  • Control Panel = which allows you to interact with the generator. 
  • Main Assembly/ Frame = which is the external frame of the generator. 

You can see how these components come together in the diagram below:


A Guide To Dual Fuel Generator Wattage

As you begin to consider your dual fuel generator options, you may notice that each generator advertises a particular wattage. As a consumer, it’s essential to choose a generator with the right wattage for you, so I’ll briefly explain it in this section. 

Generators output AC voltage, which is why they can be used to power your house. When you see a generator advertised, you will notice that two wattage figures are given: ‘maximum wattage’ (sometimes called ‘surge wattage’) and ‘rated wattage’ (sometimes called ‘running wattage’).

Maximum wattage refers to the generator’s minimum capacity, while rated wattage refers to 90% of the maximum power. As generators can only output their maximum wattage for 30 minutes or less, rated wattage is the wattage you will get when you actually use the generator. 

NOTE: As a generator owner, you never want to run your generator at maximum capacity for long. This is for two reasons: you will run out of fuel quickly, and your generator will degrade faster. 

When choosing a generator, experts recommend selecting a generator with a rated wattage that can easily handle your power needs. For example, if you need a generator with 2,000 watts, you should choose a generator with a rated wattage of at least 2,500 watts, not a generator with a maximum wattage of 2,000 watts.

What The Best Dual Fuel Generators Have in Common

Now that we’ve covered how dual fuel generators work, it’s time to dive into the best fuel generators currently available on the market. As a consumer, there are many ways to rank each generator’s quality. The best dual fuel generators have a multi-year warranty, multiple power outlets, and a protective frame made of strong metal like steel.

The best dual fuel generators also include some of these features:

  • Push-to-start or ‘electric start,’ which allows you to turn on the generator with just a button (rather than cranking it manually). 
  • ‘Switch and go’ or a ‘transfer switch,’ which allows you to switch fuel sources without turning off the generator. 
  • All-terrain wheels, which allow you to move the generator without lifting it. 
  • A protective case to keep the generator protected when you aren’t using it. 
  • Oil level indicators or a low oil meter, which show you how much oil is in the generator. 
  • A remote to control the generator from a distance.

Frequently Asked Questions (faqs)

Who makes the best dual fuel generator?

The best dual fuel generator is made by Westinghouse Outdoor. Their ‘wGen6000 Portable Generator’ is safe, well-designed, and great value for money. It hosts a 6.6-gallon fuel tank, takes propane and gasoline, and can run for up to 13 hours.

What is the best dual fuel inverter generator?

An inverter generator is a generator that converts DC power into AC power. Most dual fuel generators are also inverter generators, just by the nature of their design. The three best dual fuel generators are the ‘Westinghouse WGen6000 Portable Generator’, the ‘Champion 3,400-Watt Dual Fuel Generator’, and the ‘DuroMax XP12000EH Generator’. All three of these generators are powerful, safe, and suitable for camping, emergencies, and RV’s.

Is it worth getting a dual fuel generator?

It is definitely worth investing in a dual fuel generator. Unlike regular generators, dual fuel generators can switch between two fuel sources – giving them a longer run time. As you can run your generator on fuels like propane and LPG, it is also cheaper to run a dual fuel generator than a regular generator.

What is the quietest dual fuel generator?

The quietest dual fuel generator on the market is the ‘Champion 3,400-Watt Dual Fuel Generator’, which runs at just 59 decibels from 23 feet away. Other quiet generators include the ‘Green-Power America 5250 Dual Fuel Generator’ at 68 decibels and the ‘WEN DF475T Dual Fuel Generator’ at 69 decibels.

What is a dual fuel generator?

A dual fuel generator (sometimes called ‘hybrid generators’) is a type of generator that runs on multiple fuel sources. Usually, this includes propane, LPG, and gasoline. Compared to single-fuel generators, dual fuel generators are cheaper, use lower-cost fuels, and run for longer.

Can you run a dual fuel generator inside?

You can never run dual fuel generators inside or in an enclosed environment. All generators, dual fuel generators included, release carbon monoxide. Carbon monoxide can be toxic when inhaled. To protect yourself from carbon monoxide poisoning, always run your dual fuel generator outside in a well-ventilated area.

Is it cheaper to run a generator on propane or gas?

It is cheaper to run a generator on propane than on gas, as propane usually retails for less per gallon and has an indefinite shelf life. However, propane and gas prices fluctuate throughout the year and by region, meaning it is impossible to say that propane is always cheaper everywhere.

It is essential to take care of your generator, as a well-maintained generator can last for years and give you hundreds of hours of electricity. In this section, we’ll briefly explain how to fuel your generator, how to use a generator safely, and give you some tips for good generator care.

Fueling a Generator

Re-fuelling a dual fuel generator is easy, provided you take appropriate measures to refuel your generator safely. 

Your generator will need to be cool before you refuel it. If you add fuel into a generator with a hot engine, the fuel can ignite: causing a fire. To ensure you refuel the generator safely, always turn the machine off for at least 15 minutes prior to refueling. 

Step 1. Clear the area of children and/ or pets. 

Step 2. Prepare your fuel/s and ensure the generator is not hot to the touch. Never refuel while the generator is on. 

Step 3. Open the fuel system and pour the fuel into the fuel tank.

Step 4. Use a rag to wipe away any fuel that spills. Dispose of the rag immediately. 

Step 5. Wait at least five minutes before starting your generator. Use soapy water on the fuel nozzle to ensure no fuel has leaked. 

If you fuel your generator at night, always use a flashlight to ensure you never lose sight of the fuel while pouring it. 

NOTE: When running a generator, always ensure you keep a fire extinguisher nearby. 

Good Generator Safety

Dual fuel generators are extremely safe power sources when used correctly. However, as they are gas-powered machines, fuel generators emit carbon monoxide –  which can cause carbon monoxide poisoning. To minimize the risk of carbon monoxide poisoning, always run your generator in an open, ventilated space and never run your generator indoors or under a shelter.

If you notice any of these carbon monoxide poisoning symptoms, switch off your generator and seek medical attention immediately. 

  • Minor or major headache
  • Shortness of breath
  • Nausea and/or vomiting
  • Confusion
  • Fainting
  • Weakness
  • Dizziness
  • Blurred vision

Dual fuel generators are also hot to the touch and potentially dangerous if tipped. When operating a generator, always keep children away from the machine, run the generator upright, and take measures to prevent the generator from moving, falling, or rolling (like placing bricks around the wheels). 

Tips for Good Generator Care

To get the most out of your generator, make sure you:

  • Store your generator in a cool, dry location like the garage. 
  • While using your generator overnight or out of sight, chain the generator to something secure (like a poll) to prevent people from stealing it. 
  • Never use fuel that has been left in a generator long term, as the fuel may be unstable. Always test the quality of your fuel after it has been stored (check out our ‘Best Fuel Injector Guide’ to learn more about fuel).
  • When storing your generator long term (like over summer), store the generator without any fuel in the fuel tank. 
  • Watch your generator for water leaks, as this can ruin the engine. 
  • Secure all cords when your generator is in use.
  • Get your generator serviced and checked annually by a local technician.

Conclusion

A dual fuel generator is a fantastic investment for anyone who loves camping, owns an RV, or lives in an area where power outages are frequent occurrences. Unlike single-fuel generators, dual fuel generators can run on LPG, gasoline, or propane – making them cheaper to run for longer.
