Can I convert my generator to a tri-fuel generator?

Can’t find a tri-fuel generator to meet your needs, don’t worry. You can convert your gasoline generator to a tri-fuel generator using a conversion kit. When disaster strikes, you need more options to run your generator. You can’t depend on gasoline or propane alone. Even a solar generator won’t work properly during storms and floods. In such a situation, a tri-fuel generator comes to your rescue. A tri-fuel conversion kit allows you to run your generator on gasoline, propane, and natural gas. One of the options you can use is the Hutch Mountain conversion kit. Another kit that works great is Grenergy.  You will need a conversion kit, some basic tools like screwdrivers, wrenches, socket set, and other auto tools. The installation process requires some mechanical skills. If you don’t have these skills handy with you, you may need someone experienced to sort this out for you. A detailed video will guide you about the process.

Buyer’s Guide

Without considering various important factors, buying a tri-fuel generator is a waste of money. Buyers are required to focus on various features to get the best tri-fuel generator.

Gasoline vs. Propane vs. Natural Gas

Comparing the 3 fuel options commonly used in a tri-fuel generator is very important before making the final decision. A comparison of the fuel types will give you a clear picture of what you are buying for yourself and how to get the most out of your generator. We have compared the 3 fuels for all the factors related to the generator’s working.

Power Output: A tri-fuel will give the best power output on gasoline, followed by propane and natural gas. The reason is that gasoline has a better burn rating as compared to propane and natural gas. If a generator has 9400 watts starting wattage and 7500 running wattage on gasoline, it will give 10%-15% less wattage on propane and 25-30% less on natural gas.

Run Time: Each tri-fuel generator has a different run time according to the tank capacity and power output. For smaller generators (under 5000 watts), the run time on propane is higher than gasoline. As the generator size increases, the run time for propane decreases. Comparing the runtime for gasoline, propane, and natural gas is complicated as each fuel gives a different output power.

Availability: Under normal circumstances, gasoline is readily available across the US. Its availability is impacted at times of natural disasters and infrastructural problems. Propane, on the other hand, is available readily and can be stored for many years. Natural gas’s availability can also be affected due to natural disasters and can de-rate when the temperature falls below the freezing point. However, the best thing about natural gas is you don’t need to refill the gas tank or replace the cylinder. When natural gas is available, it is available as an unlimited fuel source.

Safety: Natural gas is the safest compared to gasoline and propane. You don’t need to deal with cylinders or gas tanks when running your generator on natural gas. It is also the most environmentally friendly fuel for generators with the lowest emissions. There is no tension in storing natural gas like gas tanks and propane cylinders. If the connections are made with care and tested before working, natural gas will not lead to any hazards. On the contrary, gasoline is highly flammable, and there is a risk of spillage while refilling the gas tank. With propane and natural gas, there is no risk of going stale.

Shelf Life: Gasoline has a short shelf life as compared to propane. When it comes to natural gas, the shelf life factor doesn’t come into play as it is supplied in gas pipes and then used according to the needs.

Portability: When it comes to the portability of your tri-fuel generator, the best fuel option is gasoline, followed by propane.

Each fuel type has its advantages and limitations. A tri-fuel generator gives you the best of the single fuel and dual fuel generator, so you never run out of electric power.

Engine and Power Wattage

The engine of a generator must be powerful and fuel-efficient. Before buying a unit, make sure its engine is well-protected under the cast iron sleeve. It is not always required to go for a tri-fuel engine with higher horsepower because these engines are less fuel-efficient or maybe louder.

Along with the engine, power output also needs your consideration. You must choose the peak and rated power wisely. Before buying a tri-fuel generator, find out how many appliances, tools, or electronics, you may need to power at home or a construction site.

Also, keep in mind that different fuels offer different starting and running power. You will get a different power output with gasoline than propane and natural gas. So, make sure you are selecting the best-suited generator that can meet all your power needs on any fuel type.

Fuel Tank Size and Runtime

The bigger the fuel tank, the higher will be the runtime. Always try to buy a tri-fuel generator with a higher fuel tank capacity to get the extended runtime. But different other factors like fuel type, fuel efficiency, and the applied load also affect runtime.

Consider the fuel tank size if you want to run your generator on gasoline. Otherwise, natural gas comes through pipelines, and for propane, you are required to buy a separate tank.

Fuel Consumption

It is also necessary to check. Some tri-fuel generators consume more fuel to power your appliances, whereas some are fuel-efficient and consume less fuel.

Fuel consumption changes according to the fuel type and the load applied. Gasoline is consumed less by these generators than LPG.

Starting System

Most people find it hard to turn on their generators manually. So, in this case, electric start is the easiest way of turning the generator on.

Power Outlets

Always focus on the power outlets because they help you to determine how many and what type of appliances and devices you can power through them.

These tri-fuel generators come with at least two 120 Volt 20 Ampere household outlets. These outlets can help users power a variety of devices. Also, a 120/240 Volt twist-lock outlet is necessary to power large appliances and tools.

Safety Features

The automatic voltage regulation system is the most important safety feature as it provides stable output power. With this, you can power your sensitive electronics without any fear. Also, the low-oil shutoff sensor is important for the safety of your engine. When the oil level goes down, it automatically shuts off the engine.

FAQ

Why Should I go for a tri-fuel generator?

A tri-fuel generator will give you freedom from depending on one or two types of fuel. You will never be left in the dark at the time of a blackout. You will have the freedom to run your generator on gasoline, propane, or natural gas. Secondly, you won’t have to deal with gasoline tanks, propane cylinders when running your generator on natural gas.

Will a tri-fuel generator power my entire home?

Yes. A tri-fuel generator will be able to power your entire home, but it depends on two things. First, your power needs, and second, generator’s output. If you don’t plan to run furnaces, heat pumps, air conditioning units, and other heavy appliances, a 5000 watts or smaller tri-fuel generator will be enough for your entire home. For heavy appliances, you will have to buy a large (more powerful) generator.

Can I convert my single fuel generator to a tri-fuel generator?

Yes. Technically it is possible to convert a single fuel or dual fuel generator to a tri-fuel generator. You will need a tri-fuel conversion kit for your generator. You may also need to make some modifications to your generator.
