They also want to attach their generator to their home gas lines for easy and convenient home use. Construction workers also have varying fuel needs. Because of their portability, they have become one of the favorite models of many consumers.

Adaptability and Flexibility

You can switch from one fuel to another to adjust to the current weather with this unit. The addition of a natural gas hook-up allows the household gas supply to run it.

It’s especially great when propane cylinder options drop because of the low temperature during the cold season. If the gas supply goes offline, you can easily switch it to gasoline or propane. 


Carrying multiple units all at one time is considerably troublesome. Therefore, having one with more fuel options is considered more reasonable. Its ability to switch from one fuel to another is incomparable to other portable ones available in the market today.

The power it gives may not be that large. However, it is enough to power most average-sized homes. In addition, you can run it using any fuel available during times of emergencies as well as its aftermath.

Once your gas line or power goes out, you can easily buy any propane LPG from your local supermarket. Aside from this, you can also use spare gas from your car as a substitute for fuel.

A portable model is an excellent electrical source for small cabins. As its name suggests, a portable type comes in handy when giving construction workers on remote sites a lighting solution. Aside from this, portable types are an excellent source of lighting at home in a power outage. 

A portable type is known for its combustion engine. It is specifically designed for the production and conduction of electrical power temporarily. It can be powered by either gas or diesel. It is suitable for small electrical appliances that use small off-grid cabins. Portable ones may not produce enough power for long hours straight. However, it perfectly suits necessities such as small freezers and television. 

They run their engines by turning a small turbine. By doing so, it creates a limited amount of electrical energy. One of the good things about this type is that it can be installed in two ways. One is by professionally wiring it in the home’s sub-panel. The other way to install it is by plugging all tools directly into the socket.  


  • They are convenient and can be moved around.
  • They’re usually cheaper.
  • There’s a vast selection out there.


  • They may not provide enough power for your home.

Natural Gas

A natural gas model is perfect for those who wish to conserve more energy since this type burns cleanly with a small amount of waste. Natural gas can be found and bought in almost any location, so it is readily available in an outage.

Aside from this, natural gas units are not costly compared to other types. It is also suitable for cold areas since it starts well in cold conditions and runs with little noise. 

Generally, it can reduce the operation cost of an off-grid cabin in the long run. If you want a cost-effective type and require minimal maintenance, then a natural gas one is suitable for you.


  • Very powerful
  • They are more powerful than gas.
  • Less noisy
  • Easy to refuel
  • Relatively eco-friendly


  • More complex to repair
  • Relatively expensive.


A gasoline type is incredibly convenient to use. Readily available fuel resources commonly power it. Aside from the convenience it gives, they are known for their affordability.

This type is budget-friendly. It is also portable and specially designed in manageable sizes. These options are also portable and suitable for long backpacking trips. It is compact and easily carried during weekend trips or while camping out. 

If you are searching for one that doesn’t use lots of power, then a gasoline model is great for you. It is considered one of the most popular types among most construction jobs. This type is also hassle-free and easy to set up compared to other off-grid types. 


Standby generators are commonly termed backup generators. They are characterized as electrical systems that work automatically without starting the engine manually. These are commonly used as a source of power during emergencies.

They run quite almost like gasoline ones and run mostly on diesel in terms of mechanism. Depending on the usage, these can provide power for a minimum of 48 hours because of their larger external tank. 

They are suitable for safety systems, particularly used in different devices such as elevators and detection systems. They’re great for fire protection and standby lighting. They can even be used for life support machines such as ICUs and ventilators. 


Diesel ones are also known as diesel Genset. It is a type that runs on diesel, as its name suggests. Although it is best designed to work on diesel alone, it can also run on a combination of diesel engines and electric ones.

For consumers searching for durable ones for off-grid cabins, a diesel type is one of the best options you can have. These models usually last a lifetime because diesel burns much cooler than other natural sources such as gasoline.

It also helps lessen the burden on the engine because of its reduced heat. Aside from their durability, diesel ones require minimal maintenance requirements. If you are looking for an affordable type and an alternative to gasoline, then a diesel one is definitely for you. 


Suppose you’re looking for an eco-friendly way of producing power for your off-grid cabin. In that case, a hydrogen model is a great option for you. Most power companies plan to develop one that runs using hydrogen.

Hydrogen can be found almost anywhere, just like water. It is non-toxic and leaves no emissions behind. Hydrogen options also produce more energy compared to other sources of fuel.

A hydrogen model is specifically designed to power larger homes and other high-powered devices like air conditioners. They are easy to operate and maintain compared to solar-powered ones.

Unlike solar models, a hydrogen one does not depend on its performance in the current weather condition. You can always fuel it up any time of the day you want, and you’re good to go. It is designed to be sturdy enough and can handle a bit of rough use. 


An inverter generator is one of the most portable and quiet models you can find on the market today. The inverter generator engine has an alternator that produces AC power.

The alternate current is converted into DC using a rectifier installed in the engine. An inverter model generally uses a magnet to output the AC and then convert it into DC after being converted back to AC. 

This system helps keep the engine running quietly while working overtime and providing high power output. This is good for homeowners who want peace around their off-grid cabin. An inverter model is 20% more fuel-efficient compared to other gasoline and diesel models. It is safe for sensitive electronic devices like smartphones and tablets. 

In addition, its speed can be adjusted automatically depending on the amount of power it needs to be used. We can also help you if you’re looking to buy a garage waste oil burning heater

What to Look For

Having one of these machines at home or in your office can be beneficial. With so many models available in the market today, purchasing the right one that fits your needs can be difficult. You need to consider the different factors, such as the price and how much wattage it can carry. Worry no more, for we have listed a simple guide that will help you choose the best tri-fuel generator for you. 

When buying one, consider these factors:

  • Wattage

If you’re planning to purchase one, you need to determine first the wattage or how much power you need. Whether you’re planning to tailgate or want to have backup power, determining the unit’s wattage should be one of your priorities.

The best way to do this is to hire an electrician, especially if this is your first time buying one. Maybe you don’t want to hire an electrician and are confident that you can do it alone. You may do so by examining the owner’s manual. Find the requirement of each appliance or device you want to power. 


Normally when you buy one of your choices, it all boils down to a portable or standby generator. As mentioned in the first part of this article, there are several types. Others include inverter and solar-powered models.

Hydrogen-powered and diesel generators are also great. Each of these can be extremely useful for particular areas. Inverter ones are a perfect source for camping and RV outings. Do we need to mention they’re great for tailgating parties?

Standby and portable ones are perfect for areas where a great source is needed. Portable ones are suitable for emergency use, such as storm power or any instances that require mobility. 


Different types of fuel can be used in these units. These include natural gas and diesel. Propane and even solar are also popular fuel types. Most consumers prefer to use one that runs on fuel readily available in their area.

Aside from availability, they also look for one that burns cleaner easily. For instance, propane emits 40% less carbon monoxide and carries a much longer shelf life.

Users can always keep some tanks closely available in case of an emergency. On the other hand, solar ones are usually preferred by people who practice eco-friendly living.

Make sure to consider all these types of fuel:

  • Hydrogen
  • Diesel
  • Gasoline
  • Natural gas
  • Solar


All types require maintenance. However, some need more repairs than others. For instance, AC generators with brushes may require frequent repair.
