How to choose a generator?

Under the generator means any alternative source of electricity generation, working offline. Today there are several types of generators, while each of them has its own characteristics. They differ mainly in the type of fuel that is necessary for their work. On the market nowadays there are a large number of models, which are represented by different manufacturers. This allows the buyer, among a wide selection, to choose the most suitable. However, this also creates a problem of choice. For example, it is better to choose which generator for the house and what needs to be taken into account when searching for the required electric generator.

Generator power

Before you choose a generator, you will need to determine the power of the device. It directly, first of all, depends on the tasks assigned to it. First, you need to calculate the total capacity of all electricity consumers that you will use at the same time. First of all, they are sources of lighting, a refrigerator, a TV, or other commonly used electrical appliances.

Thus, having calculated the power of all the devices, you will need to add to the received figure about 20-30%. The final figure will be decisive in the power of the generator. For example, for giving where construction and finishing is often carried out, 6 kilowatts will be enough for you, but a larger cottage will require a 15 kilowatt generator.

The number of phases of the generator

Before choosing a generator for the house, you will need to decide on the number of phases, as this is also the most important criterion for choosing your autonomous source of electricity. If you use only single-phase electrical wiring in your house, then you will need to purchase a single-phase generator. Three-phase models will be required in the case when the devices you have are in different phases of work.

Synchronous and asynchronous generators - which one to choose

Although this characteristic is less popular, it is also no less important than the power of the generator. For example, in order to use a generator for emergency power supply of summer cottages, construction sites may be equipped with synchronous generators, which allow connecting devices with a reactive power of 65% of the nominal value.This property does not have asynchronous models, the limit of which is 30%.

Types of engine when choosing a generator

Some are interested in the question regarding which generator to choose: diesel, gasoline or gas? You can get the answer by answering the question of the operating conditions of the generator.

A gas generator that runs on A92 gasoline is considered a very effective option. It is inexpensive, compact, while it works quietly. The main limitations of this type of generator are power and continuous operation time, since it should not exceed 24 hours.

The petrol generator is great for a small cottage, where it will provide quite comfortable living and will provide the energy necessary for temporary powering the devices. For home gasoline generator is suitable as an emergency source of electricity.

Diesel generators are more expensive than their gasoline. But they are designed mainly for longer work. In addition, they have a powerful lifespan and are considered more economical. Note that diesel fuel is also considered the safest, which also becomes a weighty argument when purchasing a model that will work on a diesel engine.Therefore, if you have a question about which generator is better, diesel or petrol, then we will definitely answer diesel.

There are also gas generators, which are distinguished by their quiet operation and increased efficiency during use. The gas generator is considered to be twice as economical, unlike the gas generator, even when operating from a gas cylinder. The power range of such generators is very wide, ranging from 1.5 kW to tens of thousands. The only drawback of such a generator is the inability to start the engine at low temperatures.
