If you are thinking about how to choose an electric generator for your company, here are some tips to keep in mind.

An electric generator is a device capable of creating electrical energy and supplying it to any installation. The use of these devices is recommended in those cases in which there is not the necessary infrastructure for it or there is damage to it that may cause a cut in the supply.

Electric generators convert the mechanical energy of a motor into electrical energy. Generally, those used at the business level are more powerful and heavier. They will be in charge of generating electricity in those places where there is no power supply for any reason.

How to choose an electric generator

There are a number of aspects to take into account when you have to choose an electric generator suitable for your business. You will have to consider whether you need a single-phase or three-phase generator, a conventional electric generator, Inverte or AVR or a diesel or gasoline generator, as well as the type of power you require and the noise level it can cause. It is also essential to know the lubricants and oils essential for a generator.

Brands such as Cummins, Hipower, John Deere, MTU, Perkins, Volvo, Yanmar or EPA are the best known and most popular in the United States.

1. Do you need a single-phase or three-phase electric generator?

Single-phase electric generators have an output voltage of 220V and their maximum power ranges from 15 to 20kVA. Therefore, they are more suitable for domestic supply.

How to choose an electric generator

Three-phase electric generators, on the other hand, have more power (above 15-20 kVA) and generate an output voltage of 380V. This type of generator is the most suitable for business use. Although in the case of having a single-phase current, if you connect a three-phase generator, its performance will be lower.

2. Is a conventional, Inverter or AVR electric generator better?

To know how to choose an electric generator, you must recognize the differences between conventional, Inverter or AVR electric generators:

  • Conventional generators: they do not have any output voltage regulation system, so the voltage is usually not very stable and with different peaks.
  • Inverter generators: they offer high current quality and a very stable output voltage and frequency; in addition, they provide improved consumption and lower noise levels.
  • AVR generators: incorporate an automatic voltage regulation system that guarantees a more stable voltage.

3. How to choose an electric generator based on fuel

It is also necessary to establish the differences between gasoline and diesel electric generators. The former are indicated for a more intensive and continuous use. They are very robust and durable and offer lower consumption and greater autonomy. However, they are also more expensive and noisier than gasoline generators.

Is better an electric generator diesel or gasoline

Gasoline-powered electric generators, on the other hand, are perfect for situations of little and not very continuous use. It is, therefore, the perfect solution for emergency cases. They work with an engine above 3,000 revolutions per minute and have a power of less than 15 kVA. On the other hand, they have a shorter service life and a higher consumption cost.

4. Think carefully about the power you need, do not waste or fall short

Another essential aspect if you are wondering how to choose an electric generator is to determine the power you need. Here you must take into account whether you are going to use the device continuously or only in emergencies. The ideal is to have a generator that suits your needs, without wasting too much, but without falling short.

If you buy a generator of lower power, it will be insufficient for the work you want to give it. But if you buy a generator of excessive power, it will not be profitable and the maintenance and consumption costs will be high.

Keep in mind that electric generators with capacities between 5 and 50 kW are mainly used for personal, residential or commercial use. Those with 50 kW or more are used for industrial use.

5. Think about what noise level suits your activity

Finally, consider the noise level when you have to choose an electric generator. Everything will depend on the place where it will be located. There is a wide variety of generators on the market, the quietest being those that are around 50 and 60 decibels. Gasoline electric generators, for example, are less noisy than diesel generators.
