What Powers a Generac Generator?

Fuel is the ultimate key to run generators. The better the type of fuel, the better the generator will work. It all depends upon what powers your Generac generators. The Generac generators are powered by three types of fuels, including natural gas, diesel, and liquid propane

Each fuel type holds its perks and drawbacks. Fuel is the most basic difference between generators which is used to power the units. It entirely depends upon the personal preferences in choosing the fuel types. Let’s take a detailed look at the advantages and disadvantages of using diesel, liquid propane and natural gas for Generac generators. 

If you are opting for a diesel-fueled Generac generator then get ready to enjoy some of its perks. It is the least flammable fuel source making it secure to use, it is less expensive to maintain the only major maintenance requirement for diesel generators is regular oil changes. Diesel engines are more fuel-efficient than petrol engines. This means longer running time when running at the same capacity. Some diesel engines consume up to half as much fuel as compatible petrol engines. 

A few of the drawbacks of diesel-powered generators include their loud noise level, they are less environmentally friendly with more emissions and diesel generators are bulky as they are comprised of large and heavy components. 

A natural gas generator works in a similar manner as the rest of the generators. The most obvious advantage of using natural gas as a fuel for powering your generators is that it is cleaner, less expensive than other non-renewable fuels, and is considered efficient. Some other pros of natural gas generators are that natural gas does not produce a pungent odor like the generators powered by oil or diesel, natural gas is also readily available in large cities since it is delivered directly through pipelines. 

Hence, when using natural gas-powered generators, fuel storage becomes inessential One of the advantages of natural gas can also be regarded as a disadvantage. Since natural gas does not require any storage hassle because it is supplied through gas pipelines. When natural calamities hit the supply of natural gas is disrupted, making you face a lack of fuel when you need to operate your generator in such situations. Apart from this, natural gas is extremely explosive. In contrast with the diesel generators, natural gas generators are more expensive to run. The lifespan of a gas generator is much shorter than that of a diesel generator. Moreover, natural gas is a limited or non-renewable energy resource. 

Coming to Generac propane generators, they are less efficient than the Generac gas generators as they produce fewer BTUs(British Thermal Units) per gallon of fuel. However, propane is a cleaner-burning fuel than gasoline, making it friendly for both the environment and your generator. In simple terms, propane produces less carbon monoxide relative to other fuel sources, especially gasoline. Releasing around half the carbon monoxide of a typical gasoline generator. Therefore, many individuals prefer propane to be the best generator fuel around. 

The greatest downside of propane generators is their complex mechanics for ordinary homeowners. This increases the greater risks of failure and makes them more difficult to fix in emergency situations. Your Generac propane generators require more planning. Though the Generac generators offer the home services of generator installation. Still, you’ll need to install plumbing between your fuel and generator. A permanent tank is also needed in the long run. Once your plumbing is done and your tank is filled, you are ready to store propane in it.

Unlike gasoline, the shelf life of propane is considered limitless as gasoline starts to degrade after a few months without the use of stabilizers. A propane generator that is not in a running condition for months is not going to be contaminated either be influenced by carbon deposits. The same can’t be considered for a gasoline generator.

What Powers a Generac Home Generator?

A permanently installed Generac home backup generator automatically turns on once the home is out of electricity. In this way within a fraction of seconds, your Generac generator restores your home’s power. It runs on natural gas or liquid propane (LP) fuel.

What Powers a Generac Standby Generator?

Generac standby generator is not a portable generator as it is equipped with 8,000 power pack series. Moreover, it has an automatic transfer switch in the house only restricted to certain circuits. 

It is a splash oil engine. Now, you must be thinking from where does this jargon has landed? The term is simple to understand splash oil if we understand the term separately. Splash is a gear-driven system for engines that is responsible to distribute engine oil to the components for preventing friction. Thus, the splash oil engine is a gear-driven engine that functions smoothly when the components are well-oiled. 

Most importantly a standby Generac generator is powered by propane. All the positive and negative aspects of using propane generators are mentioned above you can re-read them for your ease. One thing you need to keep in mind while using this Generac propane generator you must have at least a hundred gallons of propane to keep running your Generac standby generator for days. 

How are Generac home generators powered?

A permanently installed Generac home backup generator automatically turns on once the home is out of electricity. In this way, within a fraction of seconds, your Generac generator restores your home’s power. It runs on natural gas or liquid propane (LP) fuel. 

An extension cord is not required to run your Generac home generators. The Generac home backup generator safely delivers power to your home’s electrical panel. It even offers a Mobile Link or a Remote Monitoring. Now, you must be wondering how Remote Monitoring is linked with Generac generators? 

The simple answer is that it is a heavenly sent mechanism for every Generac Series Home Standby Generator that allows you to monitor the status of your generator from anywhere in the world using a smartphone, tablet, or PC. It enables you to easily access information, such as the current operating status and maintenance alerts. 


Whether it is a gasoline-powered home generator or it is a propane-powered standby Generac generator one has to be extremely careful while using them. Proper precautionary measures must be taken before installing the generators at home. 

Hopefully, this article was helpful enough to brush away all the ambiguities in your mind regarding how are Generac home generators powered or what powers a Generac standby generator.
