Manufacturers
In the domestic market of silent gasoline generators, there are essentially all eminent brands of gasoline generators, differing in cost, power, weight, including Russian and Chinese ones. You can choose a modification taking into account the needs and capabilities of consumers. In the budget segment, Elitech (a Russian trade mark, but gas generators are made in China), DDE (America / China), TSS (Russian Federation), Huter (Germany / China) are in high demand.
In this segment, there are all types of gas generators, including those for 10 kW with automatic start. The middle price range is represented by the brands Hyundai (Korea), Fubag (Germany / China), Briggs & Stratton (America).
In the premium category there are gas generators of SDMO (France), Elemax (Japan), Honda (Japan) brands. Let's take a closer look at some of the more popular samples.
Gasoline generator Yamaha EF1000iS
It is a single-phase inverter 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.
Gasoline generator Honda EU26i
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.
Honda EU30iS
The maximum power of the gasoline power station 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.
Caiman Tristar 8510MTXL27
It is 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. Power of 6 kW meets the needs of most household energy consumers. In addition, a gasoline power station can be operated by organizing repair and construction works.
Subtleties of the assortment
One of the main features of the generator installed in the power plant is its type. There are only two of them, but despite this, even they should be understood. The first type is the most common - synchronous. It is useful for a number of household needs, but unfortunately, it is not suitable for high-precision devices, as well as heating boilers. For such cases, asynchronous models come in handy. If you delve into the subtleties, then it is they that give a pure sine wave, which is so important for the high-quality operation of precision electrical equipment.
Synchronous and asynchronous device types
Some manufacturers manage to compensate for the shortcomings of the sinusoid in the first version of the design thanks to the use of additional technical devices.
Other structural elements such as motors should also be treated with caution. They are + of two types, namely:
- two-stroke;
- four-stroke.
Design and operation of a two-stroke engine
Duty cycle of a four-stroke engine
The former are less noisy, but costly in terms of maintenance, since they operate exclusively on a mixture of gasoline and oil and at the same time have low productivity.The latter are more suitable for long-term work, but will require installation in a separate room or on the street, from where their noise will be less audible.
Don't forget about the cooling system. It is especially important in continuous continuous operation. Most cars in this case have a classic air cooling system, but there are exceptions to this series, which are supplied with elements with a circulating coolant, most often water.
The air cooling system is used in semi-professional units, the alternating current of which is up to 6 kW. Therefore, they are designed for short-term operation.
Gas generator FUBAG BS 6600 A ES
The generator system allows the device to automatically reconnect when the power supply is cut off. The generator is capable of delivering power up to 6.5 kW.
FUBAG BS 6600 A ES advantages
- The cost of this model is ideally suited to the characteristics that it has.
- It is possible to transfer the start from manual to automatic mode. Even the simplest configuration already has a starter that can be started with a key.
- The device works well at low temperatures, up to - 25 degrees. The battery can start even if the generator has been idle for a long time.
- The entire structure is attached to the platform through rubber pads that prevent vibration.
- There is a control panel where you can monitor the operation of the generator.
Disadvantages of FUBAG BS 6600 A ES
- This device is very noisy and reaches up to 90 dB. When using it, you will have to solve the problem with noise isolation.
- The generation to which the design belongs also matters. Not all updated models have automatic start.
- This generator requires additional ventilation to operate smoothly.
How to reduce the noise level
Diesel generators are traditionally considered the noisiest among similar models. To optimize them, soundproof casings, mufflers and specially equipped rooms are used, in the decoration of which materials that muffle sound are used.
Different manufacturers work with their own soundproofing systems. On various models, both a conventional metal casing and a whole system made of a variety of noise-insulating materials can be installed, as a result of which the noise from the generator disappears almost completely.
The ideal option is to equip a separate building for a noisy and powerful generator. But this is not always advisable. In most cases, a quiet diesel generator is sufficient.
Rating of the best gasoline generators
The key parameter for its compilation was power, since it depends on it how many devices can be supplied with power without the risk of overheating the device. It is on this principle that the rating of the best gas generators was divided. All models included here were selected based on an analysis of cost, build quality, usability, country of origin and brand popularity.
The following characteristics also influenced our choice:
- Number of outlets;
- Output voltage;
- Noise level;
- Degree of protection;
- Station start-up type (manual, electronic or automatic);
- Fuel tank volume;
- Fuel consumption;
- Additional options (control of oil and gasoline consumption, hour meter, etc.);
- Duration of continuous autonomous work;
- Weight and dimensions;
- Equipment;
- Alternator type;
- The number of phases of the output electric current.
Analyzing the reviews, we studied the frequency of complaints about breakdowns, the high cost of consumables, the availability and ease of repair.
Overview of some generator models
Among the best generator manufacturers are Hüter, Eisemann (Germany), Briggs & Stratton (USA), Kubota (Japan). Among the Russian producers, you can see the Vepr. Manufacturing of many brands has been moved to China due to cheap labor. Until now, it is considered to be a disadvantage.
There are many vague arguments in favor of this, but here is another argument in favor of China. While in Europe they still beat each other on the head with clubs and walked in skins, the Chinese were already making silk and carving incredible things from bone. Even if generators from China are inferior in quality to the originals by 5-7%, their cost is several times lower.
HÜTER DY5000L
This generator has 4 kW at 11 HP. The engine is gasoline (AI-92), but it can also run on gas. Fuel is consumed no more than 400 g per kilowatt-hour. The tank holds 22 liters of fuel. The unit can be supplied with wheels. Starting is done manually or with an electric starter. This feature allows you to use the ATS: and turn the generator into a backup power source. Of course, everything is a little simpler than it was described in the previous section, but for 40-50 thousand rubles this is not so little.
Eisemann T 15010 DE
This model (made in Germany) with a power of 12 kW, with an integrated automatic transfer switch, has a water-cooled diesel engine and is designed for continuous operation. From it you can get an electrical power of at least 8 kW, which is quite enough for a private house. Fuel consumption is about 3.2 l / h when filling the tank with 210 l.
The generator casing and its exhaust system are good at reducing noise. The generator has three phases with a linear (between phases) voltage of 380 V, and phase voltages of 220 V. So it turns out 3 lines of 220 V. It is advisable to distribute this load evenly between the phases.
Briggs & Stratton G 110
Manufactured in the USA (not China). The generator's engine is gas, can run on methane and propane, including liquefied ones. Air cooling of the engine. Power 11 kW. Electric start. The container protects the environment well from engine noise. The generator is synchronous, single-phase. Especially for the European market, it was released for a voltage of 230 V 50 Hz. (In the US, 115 V 60 Hz.)
This range of models has been specially designed for noise reduction. 66 dB at a distance of 7 m is a very good figure for installations with internal combustion engines. The unit comes with a three-year warranty.
Practical Americans in commercial affairs did not embed the ATS in the unit, which would make it more expensive for all buyers. But those who wish can purchase it in the Russian version with original “smart filling” and a contactor.
There is an extensive set of functions in addition to ATS and condition monitoring. With the help of a GSM modem, you can control the generator from anywhere, both by SMS and via a web server on the Internet.
Kubota J112
This generator has a power of 12 kW. The manufacturer promises a power factor (cos phi) very close to unity. Diesel engine, liquid-cooled, fuel consumption 3.75 l / h. Voltage 230 V, single-phase generator. The tank holds 79 liters of fuel. Starting from an electric starter, which means that it is possible to use an external ATS.
Vepr ABP 10-230 VH-BSG AVR
This generator is Russian-made, frame, at least for sure. Honda GX630 engine. Tank 25 l, fuel consumption 4 l / h. Power 10 kW, 230 V 50 Hz, single phase. Start from an electric starter, ATS can be used. The generator is synchronous.
