What are Dual Fuel Generators?

Same as single fuel generators, these are generators that can be operated with two types of fuels to generate electricity. They can use either one fuel at a time or a combination of both fuels to give better runtime and performance. Generally, the two fuels that most generators use are a combination of natural gas & propane and diesel.

In most US factories, natural gas will already be available at the site, and it won’t need to be stored, which eliminates the problem of storing the diesel in large tanks to save space. While diesel has a low ignition point, that means it will be easier to start the generator on diesel than natural gas.

Some people think that dual fuel and bi-fuel generators are the same, mind you, that’s not the case at all. The Bi-fuel generator works on the two fuels, but they are not mixed, whereas the dual-fuel generators work on the combination of two fuels in a certain proportion or a single fuel alone.

What to Consider when Buying a Dual Fuel Generator?

Before buying a dual fuel generator, you will need to keep in mind a few important things that we have discussed below.

Noise

Generators are inherently noisy because they use an engine to generate electricity, and the engine is the main reason for the noise. This means that no matter what kind of generator you buy (except for solar generators), it is always going to be accompanied by noise.

So, it would be best if you buy the generator which produces the lowest noise. But if you come home with a dual fuel generator that creates a significant amount of noise, then it will create an uproar in your neighbors.

50 dB to 90 dB is the general range in which most of the dual fuel generato falls. The level of noise a particular generator will create highly depends on the generator output and the fuel used.

Generally, gasoline-powered generators make more noise compared to propane-powered ones. So, choose the one which makes the lowest noise when all other considerations are met.

Size of a Storage Tank

Consider the dual fuel which these generators use is gasoline and propane. The propane is available in a canister and is stored under pressure.

When you want the generator to run on the propane, you can just connect the hose to the unit. So propane doesn’t need to be stored means there is no need for a storage tank, but to store gasoline, the storage tank is needed.

Most dual-fuel generators, which are powered by gasoline, come with a storage tank, and the size of the tank can range from as small as 2 gallons to a large tank of 10 gallons. The problem with the large storage tank is its space requirement and weight, which makes the unit less portable.

So, you should choose a dual fuel generator with a small tank size if the storage space is less and you want them to be more portable because, with the increase in the storage tank size, the overall size of the generator also increases.

Power Output

The power output of the generator is measured in peak watts and running watts. The power output of the dual-fuel generator won’t be the same for both fuels; instead, they will be different.

The generator running on propane will generate less power, and if it would have been powered by gasoline, the power output would be high. This is because gasoline burns better than propane.

When supplying the generator with propane, you should expect a reduction in power by about 10%. Propane generates less power, but it doesn’t produce harmful gasses, hence keeping the environment clean.

Monitoring and Protection

If you want to know whether your generator is properly working or not, then you will need to check the voltage and frequency generated by the unit. You may also want to know different parameters related to the generator for some reason.

To make the monitoring easier, the dual-fuel generators come with an LED display and indicator lights on the control panel, along with other bunch of things.

The LED display will show the voltage, frequency, total runtime, wattage, and maintenance interval as well.

A good dual fuel generator will have a quality control panel, meaning various kinds of protection will be integrated into the control panel, like a low oil shutoff. To protect the generator if the oil level is low, the control panel also has overheating protection, overload protection, and circuit breakers.

So you may want to look for a generator that gives enough information about the condition of the generator, and enough protection measures are taken.

Portability

Portability represents the ease of moving around the product or carrying it from one place to another, and it highly depends on the size and weight of the unit.

If the weight of the unit is more, it will be difficult to move it from one place to another, and you may even require support from your neighbor if the generator is too big.

While if the generator is bulkier and big in size, it may be cumbersome to fit it into the car or the truck if you want to take it to the repair or transport it somewhere else.

Also, the size of the dual-fuel generators and their power output capabilities depends on each other. The more power you need, the size and weight of the unit are going to increase.

So you will need to choose the one which fulfills all your power requirements and at the same time stays relatively portable.

Advantages of a Dual Fuel Generator

Dual fuel generators have many advantages, and some of them are discussed below.

Reliability

The main advantage of the dual fuel generator is its ability to supply continuous and uninterrupted power in situations of a power outage or natural disasters.

They can supply the power for more than 24 hours if both fuels are properly utilized. It will be enough for many households and important places where downtime of even an hour is not allowed, like hospitals, factories, and some businesses.

When gasoline alone is used as fuel, it provides the high output wattage but to supply the high wattage, it also burns faster, which results in less runtime. Besides, most of the generator comes with tanks that can hold a few gallons of gasoline, which won’t give a runtime of even 12 hours.

On the other hand, propane burns slower, and this slow-burning will result in longer runtime, but it won’t be able to provide the wattage same as gasoline. Propane is available in canisters, so you won’t need tanks to store them.

Their availability can range from 5 gallons to 120 gallons of tanks, which can supply electricity for almost 20+ hours.

Now, if we talk about the dual fuel generator, which can work on both gas and propane, then it offers the advantages offered by both fuels. When one runs out, you can use another, and you will have an uninterrupted power supply that can supply the power for more than a day.

Effectiveness and Environmental Impact

The burning of any fossil fuel emits carbon into the environment, and these dual fuel generators are no different. They also emit gasses that are hazardous to people and the environment.

The exhaust of gasoline, when used as fuel, has a more detrimental effect on the environment than the exhaust of propane, and also, the effectiveness of both gasses is not the same. Gasoline has more BTU than propane, which means gasoline will generate more energy when it is burned compared to propane.

If you are conscious about the effect of your lifestyle choices on the environment and the reduction of a few BTUs doesn’t bother you, then the propane generator will be a good choice.

But, if you are someone who wants the same power and also cares about the environment, then the Dual fuel generators are for you, my friend. When you need more power, you can increase the proportion of gasoline, and when you don’t need that, you can use more propane and less gasoline in the fuel, the exhaust of which is easy on the environment than gasoline.

This is something that you don’t get in a single fuel generator.

Versatility

The capability to supply electricity using any of the two types of fuel makes these generators highly versatile. Dual fuel generators are for those who are always out camping or running their RV around in different towns.

There might come a time when in some remotely small town, you might not be able to locate the propane tanks.

If you are in an instant need of electricity and you have a single fuel generator that only works on propane, then the first thought which will flow through your mind would be,” I should have bought a dual fuel generator. “ Because along with propane, it also runs on gasoline, which is generally available in every town.

Furthermore, in the area where hurricanes and snowstorms are regular things, you won’t have power for weeks, let alone days. In that kind of situation, a versatile dual fuel generator will become your savior and supply the electricity using any fuel you have at hand.

Effect of Temperature

Gasoline and propane; both fuels are affected by temperature. If we talk about gasoline, then it doesn’t have a long life span; it will go bad in a matter of time if not properly stored. Besides, a hot climate makes it evaporate, so you can’t store it for longer periods, especially in summer.

On the other hand, propane works just fine in hot climate and can be stored for more than ten years, and it won’t go bad, but the downside of propane is that it shrinks.

Yes, the volume of the liquid propane shrinks in a colder climate, reducing the pressure at the regulator. The pressure may drop to that degree that it may not be able to even start the generator.

Luckily, we have a solution. You can use gasoline in the winter and propane in the summer because hot temperatures don’t affect the propane.

Durability

A simple observation would be that this kind of generator will be mostly used in harsh weather areas. This means the generator should be capable enough to ride through many of these situations. That’s why this dual fuel generator is made from durable and sturdy materials to last long.

It will keep supplying the electricity in any weather condition. These generators are built to last, but there is one culprit that can damage the generator, especially if it is sitting inside, That is gasoline. If it stays inside the machine, then it will damage the carburetor and other parts as well.

This is because when the gasoline stays idle for a long time, then the fuel will undergo a phenomenon called phase separation, where ethanol separates itself from the fuel.

After that, anything that uses this gasoline will be damaged. That’s why experts suggest not to use the gasoline which sat idle for more than 3 months.

While the propane has a longer life, it stays good for more than 10 to 12 years. This means you can use propane for more general needs, and when you need more power, you can switch to gasoline. This can only be done with dual fuel generators.

Disadvantages of Dual Fuel Generator

Everything is good about these units, but we found some things which can be considered as disadvantages and they are listed below.

Expensive

You can consider this as the main disadvantage. The upfront investment in the dual fuel generator of the same power rating will be more compared to the single fuel generator. You will need to figure out your needs correctly and invest in one that best suits your circumstances with the price point considered.

Bigger in Size

The other disadvantage will be the size of the units. They are generally bigger and heavier. The weight of most of the units will be more than 100 pounds. But to handle this weight, they are generally equipped with flat & sturdy tires, which will be good for any kind of terrain and a soft handle to have control over the unit.

Generally, the size and weight of the unit will increase with the power output.

Which is Better; Gas or Propane?

Let’s find out which one is better.

If we talk about gasoline, then it is available in almost all towns in enough quantity to run your generator, but that’s not the case with propane. In many remote places, you may not find propane tanks or canisters to use in your generator.

Gasoline has a shorter lifespan due to phase separation and fuel gum-up and can only be stored for a maximum of 3 months; after that, it will damage the machine in which it is used. But that’s not the case with propane; it can be stored for more than 12 years without worrying about a single thing.

Another aspect where the propane shines is its clean-burning ability than gasoline. The exhaust of gasoline is more harmful to the environment compared to propane, and it is relatively easier on the surroundings. Also, when it is burned, gasoline leaves behind carbon deposits, which will need to be periodically removed.

When propane is used as fuel, it generates less noise compared to gasoline.

Gasoline is highly flammable, which means storing it in a large quantity will be dangerous, while propane is the least flammable fuel, and it doesn’t pose any risk if stored in higher quantities.

From this, we can conclude that despite the easy availability and high power output capabilities of gasoline, propane is better due to its long lifespan and less impact on the environment. At last, it all comes down to your power needs and personal preference.

FAQs

Can I Power Sensitive Electronics with The Dual Fuel Generator?

For proper functioning of the sensitive electronics, it should be supplied with clean power. If it contains any spikes and surges, then there is a high possibility that electronics might get damaged. Generally, most of the dual-fuel generators tend to supply the square wave power on which most of the appliances will work but not all of them.

So if you want to power the sensitive electronics, then I suggest that you first make sure that the generator supplies pure sine wave with very little THD rating. If not, then keep your electronics away from the generator.

How to Increase the Runtime on A Dual Fuel Generator?

Dual fuel generators indeed provide more runtime than single fuel generators. In a single fuel generator, once the fuel is depleted, you will need to pour in more fuel and start it again to keep it going. This refilling will result in a downtime of a few moments, and if you live in a cold area, then your generator might refuse to start altogether.

Whereas for the dual fuel generator, you can run it on gasoline, and once it is depleted, you can set the knob to propane, and the generator will keep supplying power with minimal downtime.

How to Connect the Generator To The Home?

The first way to connect the generator to run different appliances would be through the power cords directly connecting the equipment to the socket of the generator. This may not be the ideal choice because it poses so many risks.

To supply the power with this method, you will need to lay down the wires in your home, and the distance shouldn’t exceed 100 feet. If that happens, then there will be a voltage drop in a cable, and some of the equipment might not work properly.

The other way is to install a transfer switch from where you can supply the most important circuits if the power goes out. Not only that, but you can also select which appliance you want to power. This is a more safe and hassle-free method.

Why are Transfer Switches Used for Power Transfer to The House?

If you use a transfer switch, then it eliminates most of the potential accidents. If you directly connect the transfer switch to the generator, then there may be a back feed of power which can harm the person working on a power line or the appliances will also be damaged.

The main advantage of the transfer switch is that it prevents the simultaneous connection of the generator and the supply from the grid to house circuits, which will save your appliances and the generator as well. That’s why you shouldn’t connect the generator directly to your home.
