Why Choose a Dual Fuel Inverter Generator?

Inverter generators are the epitome of peak technological advancements in portable generators. As compared to conventional alternatives, inverter generators are more fuel efficient, relatively more lightweight and portable, and operate at quieter noise levels.

Additionally, they provide stable power output that is perfect for running sensitive electronics such as laptops and smartphones.

While portable generators typically run on propane or gasoline, the more robust standby generators are powered by diesel or natural gas. Dual fuel inverter generators kick things up a notch by allowing the engine to use two types of fuel, one at a time.

What Are Dual Fuel Inverter Generators

What Are Dual Fuel Inverter Generators?

A dual fuel inverter generator, also known as a bi-fuel generator, uses two separate fuel systems to generate power. The internal combustion engines in these generators mostly burn gasoline or propane (liquefied petroleum gas).

The gasoline is stored in the generator’s fuel tank while the propane is hooked up from a propane tank using a hose and pressure regulator system.

You can switch between either fuel type with the turn of a dial or flick of a switch. In some models, the switch-over might not require shutting off the generator while in others it does.

Gasoline/propane is the most popular dual-fuel option in most inverter generators but you may find some units using natural gas in place of propane. Tri-fuel inverter generators provide even more versatility as they can switch between gasoline, natural gas, and propane.

Keep in mind that dual fuel generators differ greatly from duel-fuel options, which have to combust multiple types of fuels together to produce power.

Benefits of Dual Fuel Inverter Generators

What Are the Benefits of Using Dual Fuel Inverter Generators?

Ultimately, a dual fuel inverter generator provides you with all the benefits of either type of fuel. Using gasoline brings forth a higher power output and slightly better portability over having to carry heavy propane tanks. Additionally, gasoline is almost always readily available in most locations across the country.

However, overreliance on gasoline exposes you to its many storage issues such as volatility and short shelf life. Plus, some local regulations prohibit the storage of large quantities of this highly flammable fuel. Gasoline is also notorious for leaving gummy residues in generators and potentially damaging engine components.

Portable generators with dual fuel functionality don’t tie you down to the inefficiencies or unavailability of a single fuel type. Gas might get expensive or elusive, especially during global shortages, power outages, and emergencies.

Since you can easily switch between fuels, you also get to enjoy the many advantages of propane. These include having an indefinite shelf life, lower running costs, cleaner combustion, and incredible flexibility on your runtime.

What To Look for When Choosing a Dual Fuel Inverter Generator

As you shop for the best dual fuel inverter generator, you should consider the power output, safety features, fuel efficiency, operating noise levels, and start-up system among other things. An included hose and pressure regulator are expected with most dual-fuel inverter generators.

Further, where you intend to use the generator might help you narrow down on what features matter most.

For instance, a dual-fuel inverter generator to be used at home should have a high power output and L14-30R outlets. If you’re going for camping generators then you want a model that weighs below 50 pounds or one that comes with handles and wheels. Extendable or telescoping handles are especially popular in most portable generator models.

A dual fuel inverter generator for RV usage should at least come with TT-30R and 14-50R outlets and high power output to match.

Overall, your pick should operate at noise levels quieter than 60 decibels to avoid it being a nuisance to you or your neighbors. That said, if you want a very powerful generator then you will probably be left with units running at noise levels between 60 and 75 decibels.

The method used to start the engine-generator is also another key feature to consider. Here, you will typically be faced with two options: an electric/automatic start or a recoil cord/manual start.

A manual start excels at being super reliable while an electric start is preferred for its ease of use and convenience. Dual fuel inverter generators with remote electric starts (in the form of key fobs) deliver even better convenience.

However, you might want to consider a unit with both start methods since electric starts rely on a pre-charged battery to operate.

Power Output

As with all portable generators, power output is a key factor to consider when choosing a dual-fuel inverter generator. Pay close attention to the stated starting and running wattage of the given model to better gauge its power output.

The starting watts or surge watts indicate the maximum wattage the inverter generator can deliver at any given time. The running watts are the continuous watts needed to keep electronic devices on. Ideally, your inverter generator of choice should have a higher wattage than your total power requirements.

Keep in mind that gasoline produces higher power outputs compared to propane – a fact that doesn’t go unnoticed by manufacturers. They will most likely list the peak wattage provided by a gasoline fuel system and barely mention that of the propane. So, always consider both the starting and running watts of either fuel type before committing to a purchase.

Essential Safety Features

Your ideal dual fuel inverter generator should have several safety features right out of the box. After all, power is generated after combusting highly flammable fuels, which further emits poisonous carbon monoxide gasses. Most portable inverter generators often come with CO build-up alert sensors and automatic shutdowns.

Additionally, low-oil alert/shutdown and overload protection sensors are to be expected in most of today’s dual fuel inverter generators.

Final Thoughts

In a nutshell, a dual fuel inverter generator uses two fuel systems for optimal reliability and versatility. These types of portable generators allow you to switch between gasoline and propane, whenever it is most suitable.

Although less desirable, you may even use conversion kits to transform a gas-powered unit into a dual-fuel inverter generator to enjoy the best of both worlds.
