Power portable electric generator – how to choose yours?

The first step in choosing the ideal power generator is determining what type of fuel it should use. These machines are powered by gasoline or diesel and the choice of one or the other can make all the difference. It can be said that if you intend to use the generator for mild to medium works, mainly for outdoor parties, indoor uses, or to power a small office, it is best to opt for Westinghouse igen4500, a portable inverter electric generator that runs on gasoline. But if it is used every day for a longer time, then opt for the model that runs on diesel.

Gasoline Generator

Gas-powered power generators tend to be more affordable than diesel-powered equipment, around 30% less. Regarding noise, gasoline models are quieter. On the other hand, gasoline usually has a higher price than diesel. This means that if you want a generator to use diesel fuel frequently it is the most affordable for your pocket.

Diesel Generator

Besides the price, another advantage of diesel power generators is that they are much more robust. In other words, they are more resistant than gasoline equipment. In this way, they compensate those who want to use it constantly. After all, diesel is cheaper and the equipment will last for much longer.

Voltage Regulator (Voltage) – AVR x Capacitor

In order to choose a power generator, it is also important to understand the concept of voltage regulator. It has the function of stabilizing the energy that reaches your company or residence, in order to allow it to be permanent. In this way, it is possible to connect the most varied types of equipment, even those that are more sensitive. The electric energy generated through a combustion engine has a lot of oscillation. Therefore, the generator also needs to have a voltage regulator, to allow machines and others to be connected to it safely.

Capacitor: The capacitor is a simpler model of energy regulator, since it cannot remove all oscillation from the voltage output. Thus, it is dangerous to connect anything that is sensitive to the power generator.

AVR: AVR stands for Automatic Voltage Regulator. It is an accessory that must be present in the power generator if you do not intend to connect more sensitive equipment. This model is more modern and allows the energy produced by the generator to look the same as the power grid.


Another essential step when choosing the power generator is how to size it. For this, it is necessary to consider the consumption of all the devices and machines to be connected, which must be done in watts. In general, this data appears on the product itself or on its label. If you can’t find it, you can find the information in the manual or on the manufacturer’s website. It is essential to take into account a safety margin.

This tip is even more important if you are not sure of the equipment consumption. So if the sum of consumption of the devices was 1,900 watts, prefer a generator of 2,500 watts. This avoids the risk of overloading, which could damage the power generator, besides the devices connected to it.

Connecting UPS to Power Generator

There is also the possibility of connecting the power generator to the UPS. In this case, it is necessary to pay attention to its technology, the most suitable being the double conversion or triple conversion models. Thinking about the energy that comes from a power generator, it really is a concern that you should have when selecting a UPS. It is important to say that a power generator does not work in the same way as the UPS. Therefore, even with an ATS panel, it is normal for the equipment connected to the generator to be without power for a few seconds.
