How to Choose a Low Noise Gasoline Generator?

In an effort to buy a generator for generating electricity, most buyers are interested in such points as size, type of motor, power. Along with this, in some cases, the characteristic of external noise arising during the operation of the unit is of primary importance. Especially this question worries people who buy a generator for use in a country house.

There are no generating units that do not emit noise at all.... At the same time, low-noise generators have been created, which exclude the possibility of creating discomfort for their owners. For example, gasoline powered vehicles are not as noisy as their diesel counterparts. In addition, low-noise gas generators are mainly equipped with with a special soundproof shell (casing). By well balancing the motor, vibration is reduced and this also makes it possible to make the unit quieter.

By the number of phases and the magnitude of the electric voltage at the output, gas generators are single-phase (220 V) and 3-phase (380 V). At the same time, it is necessary to be aware that single-phase energy consumers can also be supplied from a 3-phase unit - by connecting between phase and zero. In addition to 3-phase 380V units, there are also 3-phase 220 V. They are only practiced for illumination. By connecting between phase and zero, you can get an electrical voltage of 127 V. Some modifications of gas generators are capable of delivering an electrical voltage of 12 V.

By design, gasoline units are synchronous and asynchronous. Synchronous are also called brush, and asynchronous - brushless. The synchronous unit carries a winding on the armature, where the electric current flows. By changing its parameters, the force field and, consequently, the voltage at the output of the stator winding change. The regulation of the output values ​​is carried out by means of current and voltage feedback, made in the form of a conventional electrical circuit. As a result, the synchronous unit maintains the voltage in the mains with greater accuracy than the asynchronous type, and easily withstands short-term starting overloads.

Have brushless an anchor without windings, only its residual magnetization is used for self-induction. This makes it possible to make the design of the unit simpler and more reliable, ensuring that its casing is closed and protected from moisture and dust. The only cost to this is the poor ability to withstand the starting loads that appear when starting equipment with reactive energy, for example, electric motors.

Motors of gasoline units are 2-stroke and 4-stroke. Their discrepancy is due to the general structural properties of 2 and 4-stroke engines - that is superiority of the latter in relation to the former in terms of efficiency and service period.

2-stroke generators have smaller dimensions and weight, they are used exclusively as spare power supplies - due to their small resource, equal to approximately 500 hours. 4-stroke gasoline generators are intended for the most active use. In accordance with the design, their service life can reach 4000 and more engine hours.

In the domestic market of silent gasoline generators, there are now essentially all eminent brands of gasoline generators that differ from each other cost, capacity, weight, including Russian and Chinese production. You can choose a modification taking into account the needs and capabilities of consumers. In the budget segment, they are in great demand Elitech (Russian trade mark, but gas generators are made in China), DDE (America / China), TSS (Russian Federation), Huter (Germany / China).

In this segment, there are all types of gas generators, including 10 kW with automatic start. Average price range represented by trademarks Hyundai (Korea), Fubag (Germany / China), Briggs & Stratton (America).

In the premium category - gas generators of brands SDMO (France), Elemax (Japan), Honda (Japan). Let's take a closer look at some of the more popular samples.

Is an inverter single-phase station with a maximum power of not more than 1 kW. Its small size makes it possible to operate it in a variety of hard-to-reach areas, take it with you on long journeys. The station is provided for 12 hours of battery life.

The generator weighs more than 50 kilograms. Power of 2.4 kW is enough to provide electricity for a not very large country house for several hours.

The maximum capacity of the gasoline power plant reaches 3 kW. Weight over 60 kilograms. This modification has two built-in 220 V sockets. Built-in wheels make it easier to move around the territory, the sound-insulating casing reduces noise. The battery life is a little over 7 hours. The area of ​​use is almost akin to the previous modification.

Is itself a powerful 3-phase gasoline low-noise generator, the cost of which is more than 100 thousand rubles. It can be installed both permanently and moved on wheels. The power of 6 kW meets the needs of most household energy consumers. In addition, the gasoline power plant can be operated when organizing repair and construction work.

The presented list of the quietest gas generators will allow you to make an impartial assessment. However, the final decision is made depending on the specific target destination. In certain situations, dimensions or weight. Autonomous power stations based on gasoline engines are sold cheaper, they run even in the cold. This equipment functions reliably in difficult conditions without unnecessary noise.

The following characteristics are essential:

1. Motor type. According to consumer reviews, modifications with Honda GX engines are the most reliable. They are tried and tested, simple to operate and do not need any special maintenance.
2. Protection... If the gas generator will operate without stable monitoring, then auto shutdown should be taken into account in it. For home use, a modification with oil sensors and protection against excessive heating is enough.
3. Start method. In inexpensive versions, there is an exclusively manual start. An electric starter is present in more expensive and powerful units. The main advantage of auto-start generators is that they can be started effortlessly in cold weather.
4. Power. It depends on the amount of equipment connected to the gas generator. For a backup supply of energy to the suburban area, a unit with a capacity of no more than 3 kW is sufficient.If construction equipment or a tool will be connected to the unit, then it is advisable to purchase equipment with a capacity of 8 kW or more.

And remember, to extend the life of the unit, each gasoline generator regular maintenance required... In the device, it is necessary to systematically change the oil and add fuel, as well as constantly clean the air filter.
