Gasoline generator for home and garden: device and characteristics of the unit
If an unplanned power outage occurs periodically in a private house, at a dacha or on a construction site, then you need to think about buying a generator. This device is capable of providing autonomous power supply to any object. A gasoline generator for the home is popular, characterized by ease of operation and a number of additional advantages.
5 kW gasoline generator: prices, which is better for a private house
If you do not pay attention to the additional functions and the manufacturer’s trademark, then it should be noted that the power has the most direct impact on the cost of the generator. The higher this figure, the more expensive the device will eventually cost. When choosing a generator, in no case should you start only from its price: experts recommend calculating the power of the device.
If you save money and purchase a device with low power indicators, then it will not be able to cope with the tasks assigned to it: either the electrical appliances in the house will not turn on, or the generator will be forced to work at the limit of its own capabilities. It won’t lead to anything good. The decision to buy a generator for a house with too high power indicators is also not quite right. Such a model will cost too much. In addition, an additional problem arises: fuel consumption remains significant even when the unit is not fully loaded.
Stages of generator power calculation:
- a list of electrical appliances used in the house is compiled;
- their rated power is indicated (it is specified in the passport or on the tag);
- the devices are divided into groups according to the degree of importance;
- there are devices that are used constantly;
- a power reserve is left (about 20%).
To choose the ideal inverter gasoline generator, you should additionally pay attention to the inrush current coefficient. Manufacturers often indicate the relevant information in the technical data sheet or directly on the device itself. The essence of this concept is that more power is needed to start any generator than to ensure its stable operation. Therefore, the initial power indicators should be multiplied by the corresponding coefficient.
Gasoline generator for home: classification of devices
In order not to be confused with the power indicators, it is recommended to study in detail the main classes of these devices. Technical specifications will help you figure out which is the best 3 kW gasoline generator, the price of which may vary significantly. These devices are suitable for lighting a small private house or cottage. The power of the device is sufficient to ensure the operation of the water pump and refrigerator.
Useful advice! When using the generator temporarily, it is better to turn off the devices that consume the most power. We are talking about a vacuum cleaner, an electric and microwave oven, a washing machine, as well as an electric kettle. On the other hand, a laptop, a fluorescent lamp and a TV consume little power.
To ensure a comfortable stay in the house, it is better to buy a 5 kW gasoline generator, which will allow you to watch TV, work with a computer and even cook food on an electric stove.
In order to provide electricity to a house with a large area, it is not enough to buy a 5.5kW gasoline generator, because in this situation it is preferable to rely on more powerful models. In this case, the residents of the house will be able to enjoy a working air conditioner, constant heat and hot water heated by an electric boiler. From time to time, you can connect secondary devices, for example, a vacuum cleaner. Such a device can be suitable not only for a large house, but also for an office or administrative institution.
Statistics show that a gasoline generator of 1 kW will quite cope with providing electricity to a small country house. For such structures, there is no point in acquiring too powerful models that consume a large amount of fuel.
Prices of gasoline generators for home
As in any technical device, the cost of generators directly depends on their functionality and basic characteristics. You can choose not only between single-phase and three-phase models. In recent years, universal devices have become increasingly popular.
To understand how much a generator costs, you need to familiarize yourself with its characteristics. Single-phase devices are best suited for a cottage or a small private house. Inverter generators will cost an average of 50 to 80 thousand rubles. A distinctive feature of three-phase analogs is the presence of two sockets on the panel at once. One of them is single–phase (220V/16A), and the second is three-phase (380V/16A). As a result, such a device is able to provide electricity to consumers without problems.
Quite at an affordable price, you can buy a gasoline generator for a universal type cottage. Such a device equally successfully provides electric power to both single-phase consumers and three-phase devices. The first group includes household appliances, as well as tools used in construction activities. In general, we can say that universal models are more practical. Thanks to their advanced functionality, they are able to provide users with maximum comfort. At the same time, they can work in different modes.
Gasoline electric current generator for a private house with three phases
Experts do not recommend purchasing three-phase generators for use in a private home. This statement can be easily argued. We are talking about full-fledged power plants, which have exactly one third of the total capacity for each phase. An important point is the so-called “skew” of the load. This means that each phase cannot exceed the mark of 25% of the power compared to the remaining phases.
A lot depends on the devices themselves. If only single-phase devices are used in the house, then there is no point in purchasing a three-phase generator. This will lead to an irrational use of power and maximum fuel consumption. It should also be understood that the repair of gasoline generators can be quite a time-consuming process.
Useful advice! It is quite possible to use a three-phase power plant in conjunction with three-phase automation, although all power lines need to be carefully calculated. Then they should be shifted again, taking into account a certain “skew” of the phases.
What to buy a gasoline generator for the country: price and main advantages
Gasoline-powered generators can be used in private homes and cottages. In the best way, these devices have proven themselves as a backup energy source. If the house is located in an area where there is a periodic power outage in the network, then the generator will be a real salvation.
The main advantages of gasoline generators:
- silent operation;
- compact dimensions;
- light weight;
- reasonable cost.
Modern 4.5 kW gasoline generators are optimally suited to meet the needs of a private home. For a small country house, you can select less powerful analogues.
To provide electricity to offices, shops, enterprises and various retail outlets, it is necessary to buy an electricity generator with more significant power capabilities. Power up to 7 kW in this case will be optimal. It is logical to note that the cost of such devices increases against the background of an increase in power indicators.
Gasoline generator: which is the best way to choose a start-up method
The simplest and most affordable type of generator start is a manual starter. The power unit in this case is started by pulling on a special cable. This method is very simple, but it is suitable only for household models. Any gasoline generator for a home with autorun is characterized by high power indicators and an impressive list of technical capabilities.
Generators equipped with electric starters are popular today. In this case, the start is made by simply turning the key previously inserted into the ignition lock. This method allows you to start a power plant quite quickly if necessary. The performance of the electric starter is provided by a built-in 12V battery. Due to this circumstance, the mechanism works even in the cold.
If desired, you can purchase models of generators with remote start of the electric starter. The device comes with a remote control equipped with an antenna. The power plant is started remotely. To do this, it is not necessary to leave the house. The final price of electric generators additionally depends on the way it is started.
Modern generators can be equipped with automatic reserve input (ATS). This solution is ideal for shops and retail spaces that need constant access to electricity. The corresponding devices automatically start working if the mains voltage disappears. This is very important in the summer for grocery stores that have refrigerators and freezers installed.
Initially, the price of a 5 kW gasoline generator with autorun may scare consumers away, but we are talking about very powerful devices that have excellent operational capabilities. On the other hand, it makes no sense to purchase such a serious unit for a small store or cottage.
Useful advice! Many factors affect the cost of generators. But you should pay attention to the fact that on average the cost of a diesel unit is twice as high as that of gasoline models. For this reason, consumers are advised to pay close attention to the second option.
Gasoline generator: which case is better to choose
The corresponding device has different housing options. Open-body generators are more popular. The open design allows you to place the power unit and alternator inside the most durable metal frame. This type of frame is made of pipes characterized by a circular cross section.
Country house heating options: boiler selection
Options for heating a country house: choosing a boiler by power and type of fuel. Water heating from a wood-burning stove. Features of various units.
The need to buy an open-type gasoline electric generator arises because of its functionality. He is able to cope with the following tasks:
- damping of the resulting vibration;
- stability during installation and operation;
- protection against mechanical damage and shock;
- convenient transportation.
Such a 220 W gasoline generator has a number of advantages. The main one is the fastest possible cooling. For this reason, it is open power plants that are most often used under prolonged and rather intense loads. In such conditions, there is a high probability of overheating of the equipment. The open case of the generator will not allow it to fail.
Closed-type models also have positive qualities. The housing of these generators is covered with a special noise-proof casing, which guarantees the protection of the device in case of impacts. Such a generator for a home with autorun will not be exposed to the negative effects of moisture and dust. When using a reinforced cooling system, the probability of overheating of the device will decrease. This function is especially important for professional units that have to endure significant loads for a long period of time.
Prices of gasoline generators for 220 watts
Practice shows that it is the gasoline models of the corresponding units that are the most financially profitable. All of the above characteristics affect the cost of products. Additionally, the brand and production features are taken into account. Consumers should pay attention to the warranty. Basically, it is valid for 3 years.
The price of the devices may vary significantly. A high-quality 2.2 kW gasoline generator with a voltage of 220 watts and an output current of 10 A will cost consumers about 13 thousand rubles. This device is perfect for working with a variety of single-phase tools, as well as household appliances.
About 17 thousand rubles will have to be paid for a gasoline generator with autorun, the power of which is 2.8 kW. The output current of this device is 12.2 A. The tank volume is 15 liters, so that the generator is able to work for an average of 9 hours without interruptions.
Useful advice! When selecting generators, it is necessary to take into account the type of alternator. An asynchronous type is a simple option, but it does not have a winding on the rotor. The synchronous version has a copper winding in the equipment, although the structure of the alternator itself is more complex.
More expensive is a 5 kW gasoline generator, the price of which starts from 30 thousand rubles. The output current in this case is 24 A. The tank is designed for 25 liters of fuel, and the power unit is four-stroke.
Compact 2 kW gasoline generators: prices, which is better
Such single-phase devices perfectly cope with providing electricity to a variety of household appliances that are actively used in the country or in a private house. An electric generator with average power indicators is very convenient in terms of operation and maintenance. With the help of appropriate devices, it is possible to solve problems associated with an unexpected disconnection of the main electrical supply very effectively.
Due to the presence of an automatic voltage regulator, such devices are able to guarantee the stability of the output voltage. A very convenient function is to instantly turn off the engine when the maximum power values are exceeded. In this case, the service life of the device will be quite long.
A high-quality 2 kW gasoline generator is characterized by a stable voltage. This feature called AVR is an important advantage of any device. This system is responsible for voltage equalization. This function is primarily needed by modern electrical appliances. We are talking about starting blocks for high-quality gas boilers, as well as a variety of computer equipment.
Additional device functions
Experienced consumers understand even the smallest details concerning generators, an important function is performed by the power outlet located on the device panel. In most cases, it is single-phase at 220V/16A. Three-phase generators are equipped with two sockets. The first of them is designed to power a variety of single—phase devices, the second is used to connect already three-phase devices.
The final price of welding gasoline generators also depends on the current strength. Among the additional factors affecting the cost of the device, you can highlight the display and the hour meter. Before buying generators, it is necessary to pay attention to the indicators displayed on the display. The user must not only see, but also control various parameters during operation. Among them, the same current strength, voltage, frequency, etc. should be highlighted.
The hour meter is a sign of the high quality of the device. The data recorded by this device should be displayed on the front panel of the generator. All previously worked hours must be under the control of the user. This allows you to constantly know the current technical condition of the engine. If necessary, to restore the performance of the power unit, various actions can be carried out according to the type of oil change or brush.
Useful advice! In order to fully control all processes related to the operability of the device, it is necessary to give preference to models with the most functional display. All parameters should be clearly visible even at night.
Another useful function is to preheat the engine. Today you can buy a generator for a summer cottage with heating provided by a battery. This function is provided by heating the coolant. As a result, the engine in an idle state will still be in a stable temperature regime. This allows for trouble-free start of the power unit in any operating conditions.
Summing up, it should be noted that even the most insignificant, at first glance, details and functions can affect the cost of gasoline generators. It is not always profitable to purchase the most expensive model. It is quite possible that it will have more power than the one that the room needs. Because of this, the fuel consumption will be maximum, and you can forget about the efficiency of the generator.
The popularity of the manufacturer also plays an important role. First of all, the brand must be reliable and stable. Responsible manufacturers provide a long-term warranty on their own products, which should already inspire confidence in their high quality.
