14 Best Gasoline Generators

Dear customers, we strive to make our online store as convenient, simple and, most importantly, understandable for you. Please read this text and you will be able to choose a generator for your dacha or a generator for work. We have analyzed your requests that come to us by mail and by phone, and decided to write this auxiliary text. Perhaps the most frequently asked question about generators is “Is this or that generator compatible with this or that equipment?”

What should you pay attention to first? Generator starting current . Many people forget about him. What is Starting Current?

When starting the engine (device), a starting current occurs. It occurs for a very short period of time, some fractions of a second, but in some cases it can be several times higher than the nominal value. Some appliances do not have a starting current, such as coffee makers or televisions. But for example, a submersible pump can have a starting current that exceeds the rated value by 7-9 times.

Example: A submersible pump has an operating requirement of 650 W. But at startup it needs a power of 5135 W (Multiply 650 by 7.9). It follows from this that the generator must be from 5000 W. Once started, the submersible pump will consume its stated 650 Watts.

Please, before choosing a generator, carefully read the instructions for the equipment you want to connect. It is worth recognizing that many manufacturers do not indicate the starting current value. In this case, you can always call us and we will sort out this “problem”.

Below we provide a table of starting currents for the most frequently connected devices. On the left is the type of equipment, on the right is the inrush current coefficient. Multiply the coefficient by the power consumption of your device.

Let's roughly divide the generators by their output power.

Generators up to 1000 W. – what can be connected to them? Floor fan (average power 15 W), TVs (CRT 50-80 W, LCD from 26 inches - 110-140 W, Plasma - depending on the diagonal from 200 to 400 W), Laptop (average 100 W), Desktop computer (25-45 W), you can also add to this category some Angle grinders, colloquially known as “Binders” (some of the models consume from 580 to 900 W), Hedge cutters (on average 450 W)

If you need a generator for this equipment, we recommend that you pay attention to the generators: HT 1000 L, DN 1000, DN 2100, ER 1000 I, ER 1200

Parameters for choosing a generator for a summer residence

When choosing an autonomous source of electricity, you need to pay attention to the following characteristics of the equipment:

Installation power

It is necessary to sum up the power of electrical appliances that the generator will serve simultaneously. When calculating for appliances with an electric motor (tools, refrigerators, washing machines), the starting power is taken into account. You must add 20% to the resulting value. As a rule, gas generators with a power of 2 kW to 5 kW or diesel engines with a power of 5 to 10 kW are used in a summer cottage.

Type of fuel used

Gasoline generators are not designed for long-term use. For permanent use, diesel or gas equipment is selected.

Alternator type

A synchronous generator is recommended for dachas where devices that are sensitive to voltage changes are used. Asynchronous - for a summer cottage, the owner of which is building a house, regularly uses a welding machine, erecting greenhouses and other structures.

Fuel tank capacity

The duration of operation of a diesel or gasoline generator without interruption depends on the volume of the tank. With low power equipment, the tank volume is about 5-6 liters. At average - from 15 to 30 liters.

Control mode

The following control modes are possible:

1. Manual - starting with the use of physical force (usually on low-budget models with low power up to 4 kW).

2. Electric start - start is carried out by pressing a button or turning the key.

3. Autostart - used for a backup generator that automatically goes into operation when the main power line is turned off.

The easier the launch, the more expensive the model. If you can pay for comfort, you should take a generator with electric start or automatic start.

Gasoline generator DN2100

Single-cylinder 4-stroke, gasoline. Maximum power, kVA - 2.1

Generators up to 2000 W. You can power them: Refrigerator (admittedly, refrigerators come in different varieties, both with freezers and even with two and ordinary ones, but there are many of them. Let’s take an average refrigerator, a modern one, at maximum load it requires 500-600 W.) Microwave oven ( at maximum load it will ask for 1300 W), a vacuum cleaner (let’s take a more powerful one, with the maximum possible suction power - 480 W)

For this electrical equipment you can choose from the following generators: ER 2000 i, ER 2800, ER 2800 I

Generator type

When deciding which generator is best to buy for a summer house, construction or field work, you should pay attention to the type of generator (alternator). All types of power plants are divided according to the type of electricity generation, which in turn affects the characteristics of service and the quality of the current itself.

There are three main types:

• Synchronous - they produce the most “clean”, stable current, which has a positive effect on the operation of energy consumers, but the presence of a brush assembly somewhat complicates the maintenance of the unit. From time to time it is necessary to change the brushes.
• Asynchronous ones have the opposite characteristics - they are easier to maintain, but along with an increase in load, the quality of the current also decreases. They have a closed body and are suitable for construction work on site, for example, welding.
• Inverter-type generators are suitable for powering equipment that is sensitive to the quality of current - acoustic equipment, PCs, in addition, they are quite compact, mobile and operate in an economical mode.

How to choose

The choice of any electric current generator for a private home should be based on the parameters. Selection criteria include fuel type, power and additional features that may be offered with the generator. As information, you can use reviews of generators, which will list all the advantages and disadvantages of a particular model.

Petrol, diesel or gas

The first factor influencing the choice is the type of fuel used to operate the device. On the market you can find gasoline, diesel, gas and inverter models. Each of them is adapted for use for specific purposes. Each type has its own advantages and disadvantages, so the same generator can be a good or bad choice.

Gasoline generator

The cheapest are gasoline power plants, the price of which starts from 15 thousand rubles.* The advantages of such models are the absence of noise during operation and their small size. It is because of the last plus that the generator is often used as a portable one, installed in a dacha only during the summer seasons, when people can live in the room. Despite their low price, gas generators are not the cheapest to maintain. It requires gasoline, the consumption of which will depend on the power of the device.

Inverter generators are a type of generator that also runs on gasoline. But the fuel consumption of such systems is lower. The downside is the cost, which is significantly higher compared to exclusively gasoline models. But the inverters have retained the main quality - compactness. During operation, the quality of the original current will not change from the original. If you have a large budget, it is recommended to purchase just such generators for temporary use at your dachas.

Diesel generator

Electric generators running on diesel belong to the category of more expensive models. Their starting price is 30 thousand rubles.* Compared to gasoline engines, they are a little noisy, but buyers note the efficiency and reliability of the device. Best suited for homes that require long, uninterrupted power from a generator. The device can only work well at temperatures from −5 degrees. If the temperature drops below this may cause the engine to stop working due to freezing.

The most expensive models are gas ones, since the price tag for such devices starts at 40 thousand rubles.* The choice of such an electric generator can only be justified if gas is already supplied to the site.

Important! Only specialists can connect the generator to the gas main. Carrying out such work independently is dangerous to health and life.

Gas main generator

If the line has not yet been laid, then you will have to use gas cylinders, which cause many problems due to the need to fill the containers with liquid. Since the device consumes a large amount of gas, the owner will have to refill the cylinder frequently.

Combination generators are a separate type of generator that includes models where two fuel systems are connected. For example, gas-gasoline or gas-diesel. These types of systems allow you to heat your home using two types of fuel at once. Switching between fuel types is carried out without the need to turn off the generator. Despite the fact that combined generators include two systems at once, their cost starts from 40 thousand rubles.*

Power

Before purchasing a generator, it is necessary to determine the power that will be required to heat the entire house when operating autonomously. To do this, you need to correctly calculate energy consumption.

Average electricity consumption figures

Despite the fact that a large number of devices with high electricity consumption may be installed in the house, you should not select a device that will supply power to the entire house at once. For autonomous power supply at home, devices from 10 kW are most often sufficient. More accurate calculations will depend on the number of residents and the number of devices turned on simultaneously.

It must be taken into account that if the house is rarely visited, then a generator will be required that will cover basic needs: TV, light, laptop. For such houses, a power plant with a power of up to 6 kW will be sufficient.

Coefficients for some devices

While it is quite easy to calculate the required power to power all devices, the main difficulty will arise with the size of the starting current. For refrigerators, microwaves, air conditioners and some other appliances, this figure is higher than nominal. It is the starting current that will determine how correctly the device will operate. This will require a higher power value. To obtain the correct value of the required power to power an electrical appliance with an increased number of starting currents, coefficients are used.

Note! Some devices may indicate energy consumption not in kW, but in kVA. To convert kVA to kW, you need to multiply the existing value by 0.8.

A clear example of the difference in consumption

The generator will receive the correct amount of required power only after taking into account the coefficients. You should choose a device with a power reserve of about 20%, which will avoid excessive network load.

Additional functions

Each power plant is individual. Therefore, it is necessary to take into account the available additional functions that may be indispensable for some buyers:

1. Generators are divided into single-phase and three-phase. The former are suitable for 220 Volt networks, and for premises with three-phase electricity consumers - 380 Volt.
2. Noise produced. The quietest are gasoline ones (no more than 74 dB). To reduce the noise level, the power plant is additionally protected with a casing, which allows you to set the maximum threshold to 70 dB.
3. Protective cover. This addition cannot be found in every configuration. The same applies to noise suppressors.

Generator housing

1. Volume of the tank. Fuel must be constantly topped up, so you should take care of this in advance. But you need to take into account that the volume of the tank will directly affect the weight of the device due to the amount of fuel being filled. The situation is simplest with gas generators that are already connected to the gas main, since along with the fact of connection, the need for a fuel tank as such disappears.
2. Protection against short circuits or voltage surges. Despite the fact that this option is a necessity for any generator, not all models have it. Safety devices directly affect the service life, as they prevent potential emergency situations.
3. Cooling. Most often, devices use an air system, but if the buyer wants to get the best model, then he should pay attention to devices with liquid cooling, which is found only on expensive models.

Cooling system

1. Launch type. The device can be started from a cord (the cheapest option), from a starter (middle price segment) or using an autostart system (the most expensive). The use of generators with an automatic reserve input system provides additional information on the screen - the number of hours of further operation on the available amount of fuel.

An additional factor for selection will be the availability of a service center for the purchased model. If the repair point is too far away, this will cause problems with the speed of problem solving. An additional unpleasant factor will be the need to independently order spare parts to repair a broken device.

Gasoline generator ER 7800/3 E

The three-phase gasoline alternator Ergomax ER 7800/3 E is a fairly close analogue of the ER 7800/3 model.

Generators up to 8000 W. People buy such generators to connect power to a private home. Such generators have wheels for ease of movement and you can connect not only small equipment to them, but also welding machines with a current consumption of 35 A. That is, a person can safely weld even with an electrode with a diameter of 6 mm. Such models also have another variety, that is, both standard models with an output voltage of 220 V, and with an output voltage of 380 V (three-phase). Three-phase is very common in small businesses and factories, road services and others that have three-phase equipment.

Suitable for these needs: DY 8000 LX and DY 8000/3 LX

Methods for connecting devices to the generator.

Economical way to connect.

The devices should be connected in series. Please note that first you need to connect the most powerful reactive* device and only then, in decreasing order, the remaining reactive loads, and only after that the active* loads. It is this connection method that will allow you to optimize the power of the generator.

Uneconomical connection method.

Simultaneous connection of all reactive loads to the generator. It is necessary to sum up all reactive loads, while remembering the inrush current.

* Resistive load is when all the energy consumed is converted into heat. As examples, these could be kettles, lamps, irons, heaters, electric stoves, air heaters.

* Reactive load - All other devices that have motors or capacitors. These could be microwaves, refrigerators, air conditioners.

Kinds

Generators come in several types.

By fuel type

The generator can run on diesel, gasoline or gas. There are also models that include two systems at once, which are designed for different types of fuel. The type of fuel used will not affect the final output of the generators.

Diesel generators

Diesel generators are designed for uninterrupted autonomous operation.

Diesel generator

Despite the existing disadvantages in the form of noise and sensitivity to temperatures, it has become widespread due to its efficiency, because diesel is cheaper than gasoline, and refueling is much easier than its gas counterpart.

Gasoline

The most budget models run exclusively on gasoline. But this comes with a major disadvantage - the cost of heating, since gasoline is extremely expensive compared to other types of fuel. But a model with such a fuel system is perfect for homes where the use of a generator is rare.

Gas generators

The high price is compensated by the low cost of gas. Fuel can be supplied directly from the main line, eliminating the need to constantly replace cylinders. Models may differ, since the main line generator is not designed to operate on liquefied bottled gas.

Combined

If the buyer does not know which electric generator to choose, then he can use combined versions.

Combined generator

Such devices include two fuel supply systems at once, between which you can switch at any time. Good models will cost more than gas ones due to the need to combine fuel types.

Depending on current and power output

Electronic devices installed in the house have different parameters. Some cannot tolerate even minimal voltage drops, while others operate regardless of the type and characteristics of the supply generator. To select a suitable power supply, you will need to decide on the type of alternator that is installed in the device.

Synchronous generator

A synchronous generator includes a rotor, a starter and a control unit. The device works in such a way that the motor rotor rotates, which causes the magnetic field to rotate. The output power will depend on the rotor speed.

Synchronous generator device

To avoid changes in voltage during improper operation of the device, the generator is equipped with a control unit. This is the only way to achieve the required accuracy of power output.

Most models are equipped with this method. This allows you to obtain high-quality current, and the device itself will be protected from voltage surges. But to maintain the operation of such a device, you will need to constantly replace the brushes and clean the entire generator.

Asynchronous

Models of this type consist of a starter and a rotor. The starter design is identical to that of synchronous models. There is no connection between the rotor and the rotor via electricity; it is impossible to control voltage and current.

Asynchronous models are considered cheaper due to their structure. The advantage is the closed housing, which is why the device can be used even in rooms with a lot of dust.

Asynchronous generator device

The generator's resistance to short circuits allows it to be used for welding machines. If you need to connect devices with electric motors or split systems to the network, then it is better to pay attention to power sources with a different method of generating current.

Inverter

This type of generator sends current through the network through a rectifier and battery, rather than directly like other types. They are considered the best models on the market due to their low noise level and output current characteristics. A negative aspect is the high cost of inverter devices.

A gasoline engine model is the best power plant for the home if the generator will be used for a minimum amount of time only as a backup power source. Diesel and gas models are purchased to obtain constant electricity in places of residence where electricity may be turned off for more than a day.
