Before You Buy a Dual Fuel Generator:

The Size of the Generator

Before buying a dual fuel generator, you need to consider and decide the size you want. Generators come in different sizes, each designed to provide custom energy without being excessive.

Besides the power output, the size affects the running time, maintenance requirements, and price. Generator sizes are measured in inches and often include the height, width, and length of the model. Most generators weigh between 100-250 pounds and 22-30 inches.

The size directly affects the weight; hence, you should consider the weight, especially if you plan to frequently move the generator. If the machine is too big, you may have difficulty fitting it into your trunk or even maneuvering the unit.

However, if the size is too small, it can cost you the power output. Hence, consider your power and mobility needs before buying the generator.

Wheel Kit and Portable Design

If you prefer a portable generator, you should look for features that aid in moving from one place to another. Note, portable does not always mean small; instead, it means you can conveniently move the generator from one place to another without much difficulty.

Since dual generators can be difficult to carry, manufacturers make up for this by providing wheel kits to facilitate moving to different locations.

However, some products don’t come with these kits. Instead, they are sold separately. By implication, you can buy them and add them to your existing unit. Therefore, you need to decide whether you want a generator with a portable transport option or want to buy the kit separately.

The Cost of the Generator

It would be best if you were very careful when shopping for a dual-fuel inverter generator as you must try to strike a price-quality ratio. Most people concerned about the unit’s price either end up with a cheap or an expensive generator that is not worth their time. The deal is this; overly-cheap generators are not worth much, and the same can be said for the ones that are too expensive.

True, the more expensive the machine is, the functional features you’ll get; however, you don’t need to break the bank before you can buy one. There is always a functional generator at every price level. All you need to do is create a budget of how much you are comfortable with parting with and finding a generator at that price level. The big idea is not to look too low or too high along the price chain before buying a generator.

Maintenance of the Generator

What is the best dual fuel inverter generator maintenance process? Certain dual-fuel generators are easier to maintain than others. For example, generators that use gasoline as a fuel source require more maintenance than diesel. In most cases, larger units are more difficult to maintain than their portable counterparts since they include more components. Although it should not always affect the size, you need to consider it nonetheless.

It would be best if you also chose a generator that offers the appropriate running time you desire. This can be a function of the tank size, physical size, or fuel type.

What to Consider When Buying dual fuel inverter generator?

Power Ratio of the Generator

The power ratio or output of generators is measured in Watts and is usually indicated as peak and running power output. The peak power is the maximum watts the generator can provide during operations, and the running watts is the average power it can produce during operations. Dual-fuel generators produce between 1000-12000 watts depending on the size of the generator.

Depending on the manufacturer, the watts may vary between the two fuel sources. For example, gasoline may provide more wattage than propane. We recommend you make a comprehensive list of all your tools, appliances, and electrical device you want to power. List their wattage and add them all together to give you an idea of the minimum watt requirement the generator must be able to power.

Control Panel of the Generator

The control panel lets you conveniently monitor fuel level, runtime, wattage, and other generators’ status. In most cases, the control panels feature indicator lights and LED displays; however, the quality is usually in the control panel’s intuitive design.

Not just this, but also in the number of information it displays. The control panel should be integrated into different protection systems like the low oil shutdown to protect the generator. Other protection systems include overheating protection, circuit breaker, overload protection, manual shutdown, and voltmeter. Proper integration notifies you of any emergencies so you can take action immediately.

Starting Mechanism of the Generator

The standard way to start a dual-fuel generator is either through an electric start switch or a recoil cord. The electric start device is easy to use and convenient. By storing extra electricity in an internal battery, the generator automatically starts when you flip a switch or a button on the keypad. This ignition method is the most convenient as it only requires the electricity stored by the generator. However, it cannot work when the internal battery is not charged.

On the other hand, a recoil cord requires you to steadily and quickly pull the recoil cord to start the engine. Although old, this technology is reliable but takes some effort. It may also require a few pulls to get the generator started. The advantage is that you can start the generator at any time, regardless of how long it has been sitting unused.

Neighborhood-friendly Design 

Noise-level-indicatorThe operational noise level refers to the acceptable noise level that won’t disturb your neighbors. Any operating tool will produce sound; however, the unit can still power your devices without making too much noise. Since the noise level is measured in decibels, you need to shop for inverter generators with the lowest noise levels.

Inverter generators don’t make more noise than conventional generators; however, a dual-fuel inverter generator combines the function of two into one. The noise level often depends on the generator size, the fuel used, and the power output. We recommend you shop for quiet inverter generators.

Receptacles of the Generator

Check the type and number of receptacles in the generator before buying. Most models come with standard 120V outlets, enough to power most household appliances. However, you may require the automotive 12V DC terminals or 240V outlets. We recommend you check each unit’s specification and details and compare them to different models before buying.

Fuel Capacity of the Generator

You also need to consider the fuel capacity of the generator as it directly affects the running time. The capacity ranges from 2-10 gallons depending on how large the tank is. Generally, a larger gasoline fuel tank provides more power and runtime.

However, it is not always the vase with propane since the gas is stored under pressure in canisters and attached to the generator via a hose. If gasoline is one of the fuel sources, we recommend checking to make sure the tank capacity will be enough for your needs.

Lift hook bar 

The lift hook bar is a handy part if you intend to use your inverter generator on job sites. The bar lets you attach the generator to a pulley and hook the system to lower or raise the machine. Instead of carrying it up and down ladders and stairs, you can attach a pulley system to the bar and conveniently lift the generator.

How Do Dual fuel generators Work?

Why are Inverter Generators So Quiet? Pros Cons Conclusion

The engine design is responsible for the quiet performance of an inverter generator. The technology it uses to produce power is significantly different from conventional generators because of the technology used. The technology converts a high-frequency AC into DC and then into AC. This conversion process ensures a constant noise level and creates a stable sine wave that keeps the noise level acceptable.

The design also provides more control over the voltage, frequency, and power the machine supplies. Apart from this, manufacturers also add a muffler to reduce the noise created by the generator. Plus, the design reduces internal shaking to keep the engine at a constant level and reduce noise.
