Tri-Fuel Generators FAQs

What is a tri-fuel generator?

A tri-fuel generator is designed to operate using gasoline, propane, or natural gas, giving you multiple fuel options in one generator. This flexibility can be especially useful during power outages when one fuel source may be easier to obtain than another. Tri-fuel generators in this collection are available for residential, recreational, and commercial applications. They can also be useful for jobsites, outdoor activities, and other situations where dependable portable power is needed.

Why choose a tri-fuel generator instead of a single-fuel generator?

The main advantage of a tri-fuel generator is having three fuel options available instead of relying on just one. You can choose gasoline, propane, or natural gas based on what is available and most convenient for your situation. This can be particularly helpful during extended outages when fuel availability may change. Having multiple options also gives you greater flexibility when using the generator for home backup, recreational activities, or work.

Can tri-fuel generators be used for home backup?

Yes. The collection includes tri-fuel generators intended for residential use and home backup. Depending on the generator's capacity, a unit can provide power for essential household equipment and appliances during an outage. Larger models in the collection are designed to provide substantially more power for customers with greater backup needs. When choosing a generator, consider which appliances you need to operate and their combined power requirements.

What size tri-fuel generator do I need?

The right size depends on the appliances, tools, or equipment you want to operate and how much power they require. The collection includes models with different running and starting wattage levels, giving customers options for lighter recreational use as well as more demanding home and commercial applications. Remember that some equipment requires additional power when starting, so both running and starting wattage should be considered. Choosing a generator with enough capacity helps prevent overloading when multiple devices are operating.

Can I switch between gasoline, propane, and natural gas?

Tri-fuel generators are designed to give you the ability to use gasoline, propane, or natural gas, depending on the specific model. This allows you to select the fuel source that best fits your current situation. The exact process for changing fuel sources can vary by generator, so you should follow the manufacturer's instructions for the model you own. Always make sure the generator is operated according to its specifications and safety requirements.

Are tri-fuel generators suitable for RVs and camping?

Yes. Several generators in this collection are suitable for recreational applications, including RV and outdoor use. Having three fuel choices can be convenient when traveling because you may have access to different fuel sources depending on your destination. Some models also include outlet options commonly used for recreational equipment. Make sure the generator's power output and available connections are appropriate for the RV or equipment you plan to use.

Do tri-fuel generators have electric start?

Many of the tri-fuel generators in this collection feature electric start, while some models also offer manual or remote-start options. Electric start allows you to start the generator using its built-in starting system rather than relying solely on a manual pull start. Depending on the model, additional starting methods may provide even more convenience. Check the individual generator's specifications to confirm which starting options are included.

What safety features are available on tri-fuel generators?

Safety features vary by model, but the collection includes generators with features such as carbon monoxide monitoring, CO alerts, and short-circuit protection. These features are designed to provide additional protection while the generator is operating. Some models also include digital displays that can make it easier to monitor the generator's operation. Always operate a portable generator outdoors in a properly ventilated area and follow the manufacturer's safety instructions.

Can tri-fuel generators be used for jobsites and commercial applications?

Yes. Several tri-fuel generators in the collection are suitable for jobsites and other demanding applications, including the DuroMax XP13000HXT, DuroMax XP15000HXT, Firman T08073, Firman T09371, and Firman T12071. These models offer higher power capacities that can support compatible tools, equipment, appliances, and other larger electrical loads. For example, the DuroMax XP13000HXT provides up to 13,000 peak watts, while the XP15000HXT provides up to 15,000 peak watts. The Firman T12071 provides up to 15,000 starting watts and 12,000 running watts, making it another option for more demanding applications. When choosing a generator for a jobsite, compare the equipment you need to operate with the generator's available output and connection options.

How do I choose the right tri-fuel generator?

Start by determining how you plan to use the generator, such as for home backup, recreational use, a jobsite, or another application. Then consider the amount of power you need, which fuel sources are available to you, and whether features such as electric start, remote start, CO monitoring, or specific outlet types are important. The collection offers a wide range of generator sizes and configurations, so your ideal choice will depend on your specific power requirements.
