Now that we have reviewed the top 7 best dual fuel generators for houses, let’s discuss a few things about these generators;

What Are the Different Types of Generators You Can Consider?

Gasoline generator

Commonly referred to as gas generators, gasoline generators are the most popular generators in the market. They are easy to use and are powered by fuel resources that you can readily access. Besides their ease of operation and fuel usage, another thing that makes them popular is their affordability.

Gasoline generators are pocket-friendly and designed to be as portable as possible. This makes them ideal for camping and hiking as their compactness makes it easier to carry them around.

On the downside, they produce more emissions than other types of generators and create a lot of noise when running.

Standby generators

These generators can be defined as electrical powering systems that work automatically without needing a manual start. Mainly used as emergency backup units, they use the same mechanism as gasoline generators and use diesel. However, they do have a larger external tank for fuel than gasoline models, which means they last longer.

On the downside, the larger tank makes them bulkier. They are used in specialized devices such as fire protection, detection system, life support devices, and standby lighting.

Diesel generators

These run on a combination of electrical generators and diesel engines but they work best on diesel fuel. If you are looking for a durable generator for your outdoor adventures, then diesel models are the best today. In addition to having a sturdy exterior and design, they need low maintenance.
In terms of affordability, diesel engines are a great alternative.

Portable generators

These are majorly known for having a combustion engine and are specially designed to be used in case there is temporary electrical power. These generators are either powered by diesel or gas. They may not produce enough power for many hours but can light up necessities such as TV, small freezers, and lights.

Solar generators

If you want to go green and still get a reliable source of energy when you are off-grid, then a solar generator will fit the bill. This generation uses radiation from the sun and converts it into energy. They vary in size and you can get one that suits your power needs.

Inverter generators

These are the most noiseless and portable generators around. They come with an engine that has an alternator that produces AC current. The AC is then converted to direct current. They are more fuel-efficient than standard diesel and gasoline models.

These are the 6 main types of generators.

In terms of generating power, we will discuss four important parts;

  • Engine: The generator engine creates mechanical energy, which is later sent through the conductor using a magnetic field to generate electric currents. The engines in portable models are quite small but they still provide the right amount of energy.
  • Alternator: This generates electric output, an important aspect in helping with electricity generation. This component has a needle or ball bearing.
  • Fuel system: Fuel passes through various pipes, pumps, and lines to turn on the engine and power the whole system so that it can generate power.
  • Panel: These control the model. It has outlets and switches, which provide users with crucial information.
    Understanding these various components of dal fuel generators and how they function helps you understand how these generators work.

Every dual fuel generator has a specific way illustrated by the manufacturer. Therefore, make sure that you read the user manual that comes with your fuel generator.

When using any dual generator, you should observe the following safety measures;

  • The fuels used in these generators are highly flammable and thus you should be very careful when using them
  • Carbon monoxide is one of the by-products of dual fuel generators. This gas is highly poisonous. Therefore, make sure the generator is in the open or in a separate room that has good air circulation
  • Diesel fuel is bulkier and heavier to handle and thus put this into consideration when going for hikes

  • Clean the filters annually. If you normally use your generator frequently, it is bound to accumulate a lot of particles that may clog up the fuel lines and fuel filters. Therefore, clean them up frequently.
  • Keep an eye on the battery’s capacity. The first thing to lose its capabilities in a generator is the batteries. Therefore, always check the power of the batteries now and then as a malfunctioning battery can wear out your generator extremely fast
  • Give your generator a thorough test run frequently and see if the electrolyte levels of its batteries are well balanced.
    With these maintenance tips, you will be able to use your generator for a long time.

Inverter Vs. Portable Generator- Which is Best?

Both inverter generators and portable generators produce AC power- the same power that comes from wall outlets. Although the mechanisms with which both inverter and portable generators operate are different.

Generally, the best dual fuel inverter generator models are designed to be lightweight and compact, and this applies to portable generators as well. However, in terms of noise, inverter generators are better since they produce lesser noise. This can be an advantage to people who are in congested areas.

On the other hand, portable generators tend to have bigger fuel reservoirs than inverter generators making them better if you want a generator that can run for quite some time. This makes portable dual generators better, especially if you are going outdoors.

This means that if you want more power for a long time, you need to get the best dual fuel portable generator.
