Generators are an excellent investment, whether you wish to light up a campsite or power a worksite that lacks a national grid connection. Portable power generators can also conveniently supply backup electricity during power outages. When choosing a generator, your power needs, fuel availability, noise restrictions, portability, and the number of outputs are key factors to consider. To help you select the best fit for your needs, here is an insight into the pros and cons of dual fuel generators versus single fuel generators.
What Is a Dual Fuel Generator vs. a Single Fuel Generator?
Dual fuel and single fuel generators operate in much the same way, but they differ in the type and number of fuels that can run the units. These devices can use natural gas, gasoline, liquid propane gas, diesel, or solar energy. A dual power generator can automatically switch between different fuel types to prolong its runtime, whereas single fuel generators can only use one fuel type. The changeover happens depending on fuel availability and the source of fuel considered efficient at the time.
Pros of Dual Fuel Portable Generators
Dual Fuel Generators Use a Secondary Fuel Source and Are More Fuel-Efficient
Dual power generators are a popular pick for their unique ability to operate using multiple fuel sources. A particular type of dual fuel generator called a hybrid fuel generator can simultaneously run on a mixture of fuel that forms a dependable power solution. The generator starts by consuming a primary fuel source while slowly adding the secondary fuel source until it creates a perfectly balanced mixture of both fluids.
Though the dual generators can still operate on one power source, creating the homogeneous mixture ensures a more efficient fuel consumption. Some generators can use diesel as the primary fuel source and natural gas as the secondary fuel source. Natural gas is combustible at 1,150–1200 degrees Fahrenheit, while diesel is combustible at 500–700 degrees Fahrenheit.
This engine starts by using diesel at low temperatures and proceeds to add the natural gas component once it heats up to the appropriate temperature. The engine utilizes 25% diesel and 75% natural gas to safely and efficiently generate electricity. The system can adjust diesel and natural gas in different proportions to enhance power generation and correct imbalances during higher consumption.
Dual models are an excellent pick if you live in places that experience extreme temperature changes, like freezing winters and hot summers. Propane burns better in hot temperatures, while gasoline burns efficiently in freezing weather. The dual source of fuel provides great versatility during temperature fluctuations.
Dual Options Are More Reliable in Places With Limited Fuel Availability
Is a dual fuel generator worth it? Dual power generators are an excellent option when living or working in a remote area. The lack of nearby gas stations can make single-fuel gas generators more burdensome than convenient when sourcing fuel. With dual fuel generators, you can use the most readily available fuel, depending on your circumstances. For instance, you can switch to propane and adjust your energy demands if you run out of gasoline.
While systems remain functional, you can make the necessary arrangements to refill your gasoline tank. Even during widespread power blackouts and natural disasters, basic life support systems and other power-sensitive systems remain operable with dual fuel generators. Hospitals and health care centers can greatly benefit from this uninterrupted power supply.
Dual Fuel Generators Are Durable and an Eco-Friendly Alternative
Most dual fuel generators have a sturdy design featuring all-steel frames. Their durable nature ensures they can withstand harsh working conditions and natural disasters. The robust build ensures the power source remains operable in case of accidents, such as from falling debris in construction sites.
Dual power generators are an environmentally friendly source of energy. The highly efficient fuel consumption system results in lower carbon emissions. Dual fuel generators are an excellent power source if you wish to positively impact environmental conservation and reduce your carbon footprint.
Cons of Dual Fuel Portable Generators
Dual Fuel Generators Have Decreased Portability
If portability is a significant issue for you, consider comparing the weight and size of different dual and single power generators. The protective elements in a dual fuel generator add to the unit’s bulkiness and limit its portability. Some dual types have handles and all-terrain wheels to ease transportation. They are, however, still heavier than their single fuel generator counterparts.
Also, when using liquid propane gas as a secondary source of fuel, the generator needs to maintain a link to the gas cylinder. This feature restricts the power generator’s mobility, especially on uneven worksites or terrains.
Dual Fuel Generators Have Changing Energy Output
Energy output from different fuel sources differs. Propane and natural gas, for example, have a lower energy output than gasoline. You can’t rely on these secondary fuel types to supply electricity during high energy demands. The deficit is not a significant concern as the energy output will increase once you switch back to gasoline or an adjusted homogeneous mixture of the two fuel types.
Pros of Single Fuel Generators
Single Fuel Generator Prices Are More Affordable
Single power generators have a lower initial buying cost than dual power generators. Justifiably, the cheaper single fuel model has fewer sophisticated parts than the dual fuel generating system does. It’s sensible to acquire a less costly and equally powerful single portable power generator when you don’t need to swap between two fuel sources.
A Dual Fuel System Can Be More Complex and Bulky
Dual fuel systems have a more sophisticated operating system than single fuel types. The fuel type instructions and mixture operations can be confusing to some users. To avoid the hassle of interpreting complex calculations and setup instructions, you can choose the more straightforward single fuel types.
Additionally, single fuel system generators can be valid choices if you require less power usage than what dual fuel systems offer.
Cons of Single Fuel Generators
Storing up a large amount of fuel when using a single fuel power generator can be risky and less economical. Gasoline tends to go stale or gum up, and it’s a fire hazard when exposed to open flames. With gasoline as your standalone fuel source, you may require regular repairs to keep the generator operable. For natural gas generators, you need a dedicated gas supply system that natural disasters may disrupt.
Are You Prepared With a Backup Power Source?
Power supply disruptions tend to occur without warning and can last for a few seconds to several hours. The possibility of power interruptions in the national grid puts businesses and homes at risk of untold losses. Having a backup power source is crucial to preventing mechanical failures and maintaining core operations.
Fuel generators are a backup power generation system worth exploring. Both dual fuel and single fuel generators have their pros and cons, and your selection will depend on your power demands and situation. Regardless of your choice, a backup power source helps guarantee a constant supply of electricity to safeguard your interests.
