How to choose a gas generator depending on your needs

Which model should you choose?

When choosing between models running on diesel or gasoline, you need to take into account the power of the consumed electricity. So, to provide a country house or a summer residence with electricity, diesel options are suitable. Their cost is higher, but the price of diesel fuel is lower than that of gasoline. Therefore, the use of such devices quickly pays off.

The Makita gasoline generator will do for working with power tools on construction sites where there is no permanent power source, as well as for fishing trips, picnics, trips to the country.

Devices of this type are able to work without refueling for up to 7 hours, they are more compact, cheaper and are guaranteed to start at temperatures up to minus 15 degrees.

What else to pay attention to:

1. On the engine material. Aluminum models are low-powered, but cheaper. Cast iron are designed for high power and long-term use, but their price is significantly higher.
2. By the number of engine strokes. If you need to generate a large amount of energy, you need a device with a four-stroke engine, for a backup source, a two-stroke one will suffice.
3. Phase. Units are single-phase and three-phase. Only single-phase household appliances are connected to the first. Three-phase devices are capable of servicing a wide range of complex devices - from power tools to pumping stations.
4. On the cooling system. Gasoline generators of the Makita brand are equipped with reliable air filters. Such systems can be closed or flow-through. The former provide longer cooling and the possibility of continuous operation without overheating.

Consideration should be given to such indicators as synchronicity and asynchrony.

If you plan to connect equipment that is sensitive to voltage surges, you need to choose the last type of devices.

But the most important criterion when choosing Makita gasoline and diesel generators is power. According to this indicator, they can be divided into two types:

• 2000-3000 W - for trips to nature, recreation in the country, as a reserve;
• 3000-6000 W - for working on a construction site and providing electricity for a small house.

But in order to accurately calculate the power of the purchased device, you need to know the number of devices that will be powered from it, and their starting current coefficient.

Data for each device can be found in the instruction manual. The necessary coefficients are usually indicated there. But on average for household appliances and tools, it is 1.6. And for devices with a reactive load (welding machines, refrigerators, freezers) this indicator is from 3 and higher.

The calculation of the power of a suitable stand-alone generator is very simple to find out: multiply the power of each device by the appropriate factor, add up the resulting figures and increase the amount by 10-20 percent.

What are gas generators

The main difference between different gasoline power plants is the power they are capable of producing. The power of the gas generator is calculated in kilowatts. Its size also depends on the power of the gas generator. The smallest gas generators are lightweight and can be carried with one hand. They produce several hundred watts of energy. Such generators are not suitable as a full-fledged power source for the home, and can only power one or two device. Medium-sized generators generate 2-5 kilowatts of power. There are enough such generators to fully supply the premises with electricity. The power is comparable to that supplied from a conventional network. These generators consume a lot of fuel and are large and heavy.Many manufacturers make generators with frames and wheels to make them easier to transport. The most powerful generators are designed to provide electricity to large areas such as workshops. They are bulky and heavy, consume a lot of fuel and are completely unsuitable for home use.

The main difference between different gasoline power plants is the power they are capable of producing.

The engines of different gasoline power plants differ in their cycle time. There are two-stroke and four-stroke engines on sale. The former are less reliable and powerful, delivering energy up to one kilowatt. Designed for rare use exclusively as a backup power source. When constantly working, they wear out quickly. Four-stroke engines are more powerful and more stable. They are many times better than two-stroke ones and are more practical and durable. Suitable for serious tasks.

Gas generators have different types of generator device. There are asynchronous and synchronous generators. Synchronous generators are preferable, since during their operation there are fewer voltage surges, which reduces the risk of failure of some electrical appliances. Such generators are ideal for home use, but they have a significant drawback - they are sensitive to the external environment: moisture, cold and dampness. Asynchronous generators are bad for jumping voltage, but they are made in a sealed case, which is why they can be used in harsh conditions: in rain, severe frost and snowfall.

We should also mention the inverter gasoline generators. These are generators that are distinguished by stable voltage, compactness and better performance (quiet, emit less harmful fumes). Such generators are primarily used to power servers, computers and other electronic systems, but they can also be used for domestic purposes, if they are not confused by their relatively high cost.

Types of generators

Gasoline power generators are divided into several types depending on various criteria.

By the number of phases, they are:

• Two-phase generates an electric current, the voltage of which is equal to the voltage of the household electrical network, that is, 220-230 V. For connection, such devices have only 2 phases.
• Three-phase generates a higher voltage current, which is 380 V. They are used to maintain the operation of equipment with high energy consumption (for example, some types of tools). They have 3 phases for connection.

Depending on the type of generator, the devices can be:

• Synchronous models are the traditional version, the design of which provides for the presence of windings on the rotor. The electromagnetic field on this part is created by supplying electricity to them.
• Asynchronous appliances have no rotor winding. Sources of constant magnetic radiation are installed on it (as a rule, magnetized plates made of ferrite or other similar material).

An asynchronous generator is more reliable than a synchronous one, since it does not have brush contacts. It also has no risk of rotor winding burnout. However, this type of technique is less efficient. In addition, the devices do not withstand high starting loads.

There are 2 types of equipment depending on the purpose:

• Household models are compact and lightweight, capable of supporting power up to 4-5 kW and running uninterruptedly for about 5 hours.
• Professional equipment is much more powerful (up to 30 kW) and is able to function offline longer (up to 10-15 hours). It is often large and heavy.

What kind of gasoline generator would you buy yourself?

FramePortable

By form factor, generators are divided into:

• frame - a steel frame is used as a basis.
• portable - more compact and resemble a small suitcase.

Other usefulness

Few people know, but such machines can not always be appreciated exclusively externally. Thus, the dimensions of the model do not in all cases reflect its performance. Some products from different manufacturers may have similar dimensions, but they will differ in the capacity of the fuel tank. The larger it is, the longer work will continue without refueling. This should be taken into account if the machine is used not as an alternative source of energy, but as the main one.

If the problem of generator noise is still critical, you should pay attention to those that have a soundproof casing in the package. It will not only be a good barrier for extraneous sounds, but in some cases will also protect against undesirable weather conditions, such as precipitation and wind, directing dust directly to open structural elements. 13

An important aspect of the use of machines is the availability of power outputs in the form of terminals and sockets. The former will come in handy when connecting car batteries and other accessories with a voltage of 12V, while the others will come in handy with the constant operation of all kinds of devices from power tools to floodlights. Some of them will require a 220V connection, while others will require 380V. Some of the models in the assortment will have two or even all three connection options, in some cases even duplicated several times, but their cost is often unreasonably high. Therefore, it is worth deciding in advance whether it will be required to connect electrical appliances with a three-phase power supply, or whether a single-phase one can be dispensed with.

Control elements over the operation of the unit, such as a voltmeter, a voltage switch button, sockets, terminals, operation indicators are placed on the front panel

conclusions

Speaking about the features of such a technique, one cannot fail to mention its shortcomings. Chief among them is the running time. For each model, it is limited not by one, not two, but by a combination of factors. Manufacturers indicate it in the instructions, and sometimes on the device case, so that the user does not forget to turn off the devices in a timely manner. At the same time, part of the range has automatic shutdown functions, allowing you to operate the device without a twinge of conscience and not worry about maintenance.

The spread in the maximum operating time in the nominal mode will differ significantly even within the line of one manufacturer. Some machines will work only 3-4 hours, while others about 11 hours. But not everything is so simple.

Remember safety. It is not recommended to turn on the unit near any room, so that exhaust gases do not penetrate a window or door.

With an incorrectly selected load, the generator can show malfunctions - make incomprehensible sounds, work in jerks, which ultimately will lead to the need for repair

That is why it is important not to select a model with an excessive performance headroom.

Finally, pay attention to the indicators of convenience and attractiveness of the appearance. Regarding the first - take care of a comfortable launch. So, using a manual starter becomes a real hard labor when the model has a sufficiently high performance.

Therefore, it is advisable in this case to choose a similar device, but with the launch using a key

At the same time, a certain part of the audience still trusts Japanese quality more. In addition, there is always the opportunity to use the services of a service, to replace the necessary parts. Users note that generators work without breakdowns for a long time, and additional options make operation more comfortable and safe.

If you read the reviews, we can conclude: Hitachi gas generators are quite reliable, they quickly pay off the investment.

Criterias of choice

For the successful selection of a suitable generator that will be used at home or summer cottages, it is preliminarily determined with the following questions:

1. Required power of the device. It is determined by a preliminary calculation of the expected load, which is calculated by summing the capacities of devices (up to 10 or more) that can be connected to the station at the same time.
2. Output voltage (220 or 380 V). It is determined depending on the requirements for the equipment or tool that will power the station.
3. What electrical appliances will power the generator (the stability of the output parameters matters).
4. How often will it be operated. When using the device as a backup power source, and when working for a relatively short period of time, it is better to stop at a gas generator. A diesel device can also easily cope with this, but for short-term switching on it is less preferable.
5. What resource the device has. Generators with a small resource (500 hours) are lightweight, mobile and have a low price. It is quite suitable if its inclusions are short-lived. When operating the device for more than 7-10 hours, you should choose an engine with a large motor resource. Usually, for continuous operation of the device for a long time, and when sufficient power is required (more than 10 kW), a diesel generator is installed, which has a long service life, reliability, efficiency, and a stable output voltage.
6. How important is the noise level during the operation of the device.

If a generator is required only to compensate for the lack of light several times a year, then its purchase will not be advisable from the standpoint of cost savings. In such cases, food in a summer cottage can be cooked on a camping gas burner, the phone can be charged from a car cigarette lighter, and food can be stored outside (blackouts occur mainly in winter), or you can purchase a cheap inverter option.
