7 Best Dual Fuel Inverter Generators

In today’s digitally connected world, a reliable power source is no longer a luxury but a necessity. From powering essential appliances during outages and running tools on a job site to providing power for camping trips and tailgating events, a dual-fuel inverter generator provides versatile and efficient power on demand. They offer the convenience and flexibility of running on both gasoline and liquid propane (LP) gas, making them ideal for diverse situations. This dual-fuel capability is particularly useful during emergencies where access to one fuel source might be limited.

According to experts, these three main factors play a crucial role in the selection of these generators…

  • Power Output – How many appliances can a generator run simultaneously is determined by its power output (starting/peak and RMS/continuous power). The power of these generators will range from 1000 to 7500 watts. Choose a generator based on your power requirements. Usually, basic needs (like lighting or charging devices) require a generator with lower wattage, whereas, running multiple high-power appliances like ACs, or refrigerators, look for generators with higher wattage.
  • Fuel Efficiency – The runtime and operation cost of the generator depends on its fuel efficiency. Being a dual-fuel  (gasoline & propane) generator, they perform differently based on the type of fuel used. For example, gasoline provides higher power output, whereas propane burns clean and offers longer runtimes. So, opt for a generator with a fuel efficiency offering 8 – 10 hours of runtime at 50% load without often refueling.
  • Noise Level – Mostly, these generators are used in residential or recreational areas, so the noise level is an utmost consideration. Look for a generator operating at a noise level of 50 – 65 dB, resembling a conversation at home. Thus, it provides comfort and peace during its usage, especially in camping or RV settings, where a quieter operation is foremost required.

Factors To Consider When Choosing The Best Dual Fuel Inverter Generators

Whether for home backup, recreational activities, or work sites, making an informed choice will ensure reliable, efficient, and safe power delivery for years to come. However, selecting a perfect dual-fuel inverter generator isn’t that easy, you should carefully consider various key factors along with your power requirements and align them with your usage environment to find your perfect power companion.

Now, let’s get into the details of factors to be considered…

1. Power Output

The power output of a generator is the most important thing to be considered, as it determines its handling capacity of your devices and appliances. It is typically measured in watts (W) and is usually divided into starting watts (required to handle surges during start-up) and running watts (powers the appliance as an average for continuous operation, RMS). The running watts are, however, more critical for the safe and efficient operation of your devices, rather than starting/peak watts.

Usually, most common household appliances, such as lights, a refrigerator, and smaller electronics, would require a generator between 2000 and 4000 running watts. Meanwhile, some more heavy applications, such as powering ACs or multiple large appliances, would need a generator of at least 5000 to 7500 watts. Therefore, one should calculate the total power requirements before buying a generator to prevent overloading or underpowering the system.

2. Fuel Efficiency (Gas Vs. Propane)

The fuel efficiency of a generator directly impacts its convenience of usage and overall operational cost. We all are aware that these dual-fuel generators operate on two main types of fuels – gasoline and propane. Gasoline, in general, has the highest energy density and can offer slightly longer run-time per gallon compared to other fuels like propane or diesel. On the other hand, propane fuel burns cleaner, emits fewer greenhouse gases, and is more inexpensive than gas in some locations. Some modern generators have very impressive fuel efficiency, as they run over 12 hours at 50% load on gasoline and around 9 to 10 hours on propane. It is always ideal to check their specific fuel consumption rates and buy a model offering a perfectly balanced efficiency on both these fuel types.

3. Noise Levels (dBA)

It is vital to consider the noise level (sound emitted during the generator’s operation), especially while using in residential, camping, or outdoor activities. These inverter generators are built specially for quieter operation as opposed to conventional ones. Therefore, while running, their noise level will be 50 – 60 decibels (dBA) at 25% load, which resembles normal conversation noise. So, these generators will certainly ensure reduced disruption for you and your neighbors. Also, go with the most up-to-date models that come with more advanced muffle systems or eco-mode features, wherein engine speed adjusts to the load, thereby assisting in a quieter operation.

4. Runtime

You are supposed to know, as a user, how long the generator would run on a single fuel tank. Exceedingly useful in outdoor usage and in some emergencies such as extended power outages or holding some outdoor events wherein running a generator for a long time is necessary. This dual-fuel inverter generator mostly comes with a runtime of up to 8-12 hours at 50% load. So, buy a generator with a bigger fuel tank or enhanced fuel efficiency to reduce the number of tank refills, which lets you enjoy greater convenience and peace of mind.

5. Portability And Weight

Do you relocate your generator regularly or use it mainly outdoors? Then just ensure that you check its weight and portability. Mostly, these dual-fuel inverter generators will weigh from 50 to 200 pounds depending on their power capacity. Besides having a better space, it is important to opt for a compact and lighter generator under 100 pounds, with ergonomic features like built-in wheels and sturdy handles for easy transportation and handling.

6. Safety Features

Check out the safety features provided by the generator, be it user protection or the longevity of the generator and the connected devices. This will ensure it has those essential features, such as low oil alerts to avoid damage to the engine (or) automatic shut-off systems activated in case of oil or fuel shortages. Another great value-added feature is the surge protection of appliances connected during voltage fluctuations. An investment in a generator with high safety features would ensure that the equipment operates smoothly with reduced risks, even for its extended usage.

FAQs:

1. Are dual-fuel inverter generators better than single-fuel generators?

Yes, they are more versatile, convenient, and better options than single-fuel generators. They offer flexibility in fuel choice (either gasoline or propane). Single-fuel generators might have a slight edge in efficiency due to specialized optimization for one fuel type. The best choice always depends on the user’s specific needs and priorities.

2. Is it easy to switch between fuels in dual-fuel generators?
