Advantages and Disadvantages of Tri-fuel Generator

Every technology has some good and bad sides so is the case with the tri-fuel generator. Now we will discuss the advantages and disadvantages of these generators as per our own experience.

Advantages of Tri-Fuel Generator


Tri-fuel generators are highly convenient as they bring you the flexibility of using all three fuel types’ propane, gasoline, and natural gas. In a time of emergency, if propane or gasoline isn’t available, you can hook up your generator to your house’s natural gas pipeline.

Advantages of Tri-Fuel Generator

This method is very beneficial, especially in the winter when propane and gasoline aren’t readily available. Tri-fuel generators make your life easy and simple without worrying about power outages in the severe winter season.

Easy to Transport

All the tri-fuel generators are very compact and lightweight. These are the latest technology generators and are especially preferred by most campers. Wheels are located on the bottom side of the generator and you can easily carry them wherever you want. Because of these advantages, these tri-fuel generators are loved by everyone.


As we have discussed earlier, tri-fuel generators can run on all three fuel types and you can easily trade your generator from one type to another by just changing the hose some generators have the automatic shifting option when the sensors detect the lower level of fuel in them. What else do you want?

Moreover, you can carry them easily with the handle because of their compact size and lightweightness.

Disadvantages of Tri-Fuel Generator


There are not so many disadvantages of tri-fuel generators but the one we have studied and asked people about is its price. Technology is very expensive and tri-fuel generators are the epitome of technology. So, we can expect prices to be higher than ordinary generators.

If you have a tight budget and can’t buy this and this is a big downside of this amazing generator.

Things to Consider Before Buying – Buying Guide

Buying anything whether it’s cheap or expensive needs some expertise. Here we will discuss the things to consider before buying a tri-fuel generator. So, let’s have a quick view;

Things to Consider Before Buying – Buying Guide

Run time

Running time is an important factor in selecting a generator. There is some question that one should ask himself are you purchasing it for home or for camping? Are you going to use it in power outages or at night only? Are you going to use it for a very long period of time? Never forget that the generator will wear out depending on how frequently and how long it is used.

The convenient Fuel source for you

As tri-fuel generators run on all fuel types still you must keep in mind which one you are going to use mostly. As for your knowledge, higher surge and operating watts are provided by gas, but due to its limited shelf life, it can quickly degrade your generator engine over time. Instead, I will recommend you choose a natural gas fuel source as this is easily available. You just have to connect it to the source supply.

However, compared to the operating or surge wattage offered by gasoline or propane, natural gas is not as powerful. Fueling with propane has power ratings that are comparable to those of gasoline. Furthermore, because propane has a longer shelf life, it makes the generator function more effectively.

Location of the Generator

The location of the generator matters a lot. You can use your generator for activities outside in addition to utilizing it at home, such as road vacations and parties. So, if you want to use the generator for the home only, you can also purchase a dual-fuel generator that is much more affordable.

Electric outlets

If you observe the interface of the generator you will notice that there are many electric outlets present on the generator. And all of these have different volts and uses. Therefore, it is essential to take the variety of power outlet types into account when choosing a tri-fuel generator and which one is suitable for you.

Electric outlets

How many gadgets you can turn off using the generator depends on the number of outlets. 120 volts outlets are present on the generator and you can power practically everything with these many outlets. You can charge practically all of your devices with this many outlets.

When buying some highly sensitive devices like freezers and refrigerators, it’s also a good idea to think about whether they have a (120V/240V) twist-lock style power socket. For recharging mini-electronics devices, you can also search for items with USB ports.

An AVR System

The generator’s voltage output can be adjusted using the AVR system, or automated voltage regulator system. This system is very useful and essential for you as it saves your electric appliances from getting damaged because of fluctuations. It maintains a stable voltage output.

Your gadgets, such as computers and cell phones, could be harmed, for instance. However, you won’t require an AVR setup for high-voltage appliances.


If you are concerned about the generator’s impact on the environment, you might want to opt for something that is EPA and CARB-approved. You might also try to find a company with a solid reputation for customer service.

Tank Size for Fuel

You must also take into account the fuel tank capacity when choosing a tri-fuel generator. The size of the fuel tank, however, is only important if you use gasoline to power your generator; if you use natural gas, you can acquire your fuel from the pipelines, although propane requires a tank.

Fuel tanks have different capacities depending on the generator. For instance, a 15-gallon tank can be what you discover. A 7-gallon tank is another thing you’ll see.

Tank Size for Fuel

In addition, the tank capacity more commonly determines the generator’s size. The frequency of feeding your generator is also determined by it. The more frequent filling is necessary for a smaller tank.


The cost of a tri-fuel generator is high. In reality, it is pricey and isn’t affordable for everyone. It should therefore be strong and long-lasting. You would want to make sure that your purchase has a decent warranty as a buyer. It ought to have a warranty of at least three years. Therefore, it will be beneficial to look into the warranty before making a purchase.

Tri-Fuel Conversion Kits for a Generator

There are some people who own a dual-fuel generator but now they want to have a tri-fuel generator for their needs. But Wait! Don’t spend an extravagant amount on buying a tri-fuel generator as they are highly expensive.

You can easily convert your dual-fuel generators into tri-fuel generators by spending just a small amount on a conversion kit. All you have to do is follow the simple and easy steps carefully and thank us later.

Many companies manufacture their conversion kits as they are in high demand nowadays. These conversion kits accompany all the accessories like space, gasket, bolts, and other hardware. Conversion kits have a regulator that permits fuel to flow through the engine while there is suction.

You can attach your house’s natural gas pipeline with this kit and your generator is ready to run on natural gas.

Tri-Fuel Conversion Kits for a Generator

Now follow the steps for conversion;

Step#1: The air filter housing that is located on the front side of the generator’s carburettor needs extra care. Try not to disturb the air filter and gasket and leave them as they are. When putting the generator back together, you’ll need them.

STEP#2: If your conversion kit included a spacer, this is where you would use it to create some more room in front of the carburetor. A set of studs could also work. By screwing the spacer/studs into the bolts protruding from the carburetor, i.e., where the air filter housing once was, you can add more room.

Teflon tape is a good choice for this procedure since it enables you to slide the adaptor back off if you need to adjust the carburetor. Teflon tape also makes sure that the threads are completely closed.

STEP#3: Replace the gasket before reattaching the filter housing. Any exposed area would allow air to enter behind the filter housing, therefore avoid it.

STEP#4: Most generators require drilling on-demand regulators onto the frame through the bolt. As there is a chance of drilling into the gasoline tank, this procedure is delicate. So, take caution. Ensure that the regulator attachment is pointing downward as well. If you’re overly concerned about drilling, order a conversion kit with unique regulator installation hardware.

STEP#5: The hose connects the on-demand regulator’s output to the carburetor adapter. Hose clamps are required at both ends. Nevertheless, if you have only one clamp, put it to use at the outlet end.

STEP#6: Gas hose number two is required to connect natural gas. The on-demand regulator is connected by a gas line to the gas line in your home. For your on-demand regulator to operate smoothly when connected to the natural gas line, you might also need to adjust the set screw.
