Which gasoline generator is better inverter or standard?

Rating-2021: Top 10 best gasoline inverter electric generators

Hi there! Today we will talk about inverter generators. Compared to other stationary current sources, they are compact in size and high output signal purity, which allows them to be used to power equipment that is sensitive to voltage fluctuations. Operation and maintenance of such devices does not require special knowledge. most units require little or no intervention from the owners throughout their lifetime.

The price range presented in the market is very diverse. from inexpensive and simple models with limited functions to the highly sophisticated ones. With their help, you can supply electricity to household appliances that are sensitive to voltage fluctuations in the absence of electricity. For an untrained person it is almost impossible to immediately understand such a variety. For your convenience, we have analyzed the market and selected the seven best inverter generators you can buy in 2021.

Inverter generator or conventional generator. which is better?

The modern market of electrical equipment currently offers two types of generators, with the help of which, burning carbon fuel (gasoline, diesel fuel or gas), you can get electricity. This problem is urgent, because the work of domestic power supply organizations leaves much to be desired. And the occasional power outage, proof of that. So, in this article we will be interested in one question: inverter generator or conventional generator. which is better? To understand this issue, it is necessary to consider the principle of operation of the two types of generating equipment, the positive and negative sides of design and operation, and pay attention to some positions concerning the economic side of the matter.

Inverter generator

Classic alternator

The principle of operation of an ordinary generator is quite simple. Carbon fuel by means of a standard engine, arranged for a particular type of fuel, drives the shaft, which is directly connected to the alternator. The latter is an alternator that converts mechanical energy into electrical energy by means of the rotor winding and magnets installed in its design.

That is, no intermediaries, so it is very important that the rotation of the shaft, and therefore the rotor, occurs at the same revolutions. Decrease or increase the speed of rotation leads to a decrease in the quality of electricity. This is the main disadvantage of the classic generator, because over time, the rotating parts and components wear out, which leads mainly to lower rotation speed.

  • But that’s not all. There is one, if I may say so, negative economic point with the classic generators. If the unit will not be fully loaded (below rated), its fuel consumption will be high in comparison with the loading indicator. And especially if in this mode the generator will work for a long time. In order for you to understand what we are talking about, here is a simple example.

You bought a 5 KW generator and the power consumption of all appliances and lighting in the house is about 3 KW. That is, almost half of the generating set will work at idle. But at the same time it will “eat” the fuel for 5 kW. Therefore, before you buy this equipment, it is necessary to accurately calculate the power consumption in the house. And already under it to buy the device.

  • If a classic type generator does not operate at full load, soot begins to collect inside the internal combustion engine. And it will lead to a decrease in efficiency, that is, again, will directly affect fuel consumption. In addition to all this it is necessary to do the repair more often, which is also not a pleasure.

Many consumers, when buying a generating set, rarely look at the instructions or the passport. And it is in these documents that manufacturers warn that the operation of the generator below 25% load is strictly prohibited. Usually, there is also a specified period during which such load is allowed, because there are many emergencies in life. This term is indicated in hours per year. That is, exceeding this figure removes all responsibility of the manufacturer.

The classic gasoline generator

Warning! The most surprising thing is that a large number of complaints from consumers come from this very reason. That is why it is recommended to study the accompanying documents first, and then to purchase or operate a generator.

Despite the fact that the generators with the classic technology of generating electricity has so many disadvantages, they also have one fairly significant pole. it is a reasonable price of equipment in comparison with other varieties. Let’s add here a good reliability of the unit and a wide range of capacities. As for reliability and long service life, all this will be in reality, if the generator is loaded to its capacity and periodic maintenance is done.

Inverter generator

The inverter generator has a completely different way of generating electrical energy, although it is still the same alternator. It does not supply electric power directly, as it does with the classic model. There are several intermediate units in its design, the main of which is the battery.

How electric alternating current is generated?

  • At first, everything happens the same way as in the classic machine. That is, the internal combustion engine turns a shaft that is connected to an alternator rotor. The latter generates alternating current.
  • The current passes through the power electronics and is turned into direct current. It is used to charge the battery.
  • Now, in order to get AC current again, after the battery, an inverter is installed, which produces the current of the required voltage, namely, 220 volts with a frequency of 50 Hz.

Why do we need such a complex circuit, what is its advantage?? Again, everything rests on the consumption of hydrocarbon fuel. For such a unit there is no need to maintain a constant rotor speed, it can be small enough, and it will be enough to charge the battery. True, with reduced rotation will increase the charging time. But in this case it is not so important. It turns out that the lower the rotation speed, the less fuel is consumed.

In addition, it can be said that this parameter affects the size of the generator. It becomes compact and lightweight. The plus side is that it operates noiselessly.


  • Cost of equipment. It’s almost twice as efficient as a classic.
  • The constructive feature. the battery is an integral and indivisible part of the generator. That is, if the battery is out of service life, you will have to replace the entire unit.

Classic gasoline generator

The principle of operation of this model is simple. Carbon-type fuel goes into the classic motor, capable of running on gasoline or diesel fuel, which causes the shaft to move. The latter is combined with an alternator. This device is an electric generator, capable of converting mechanical force into electricity through the winding and magnetic elements.

An ordinary gasoline generator for home use is devoid of intermediaries, which allows you to rotate the rotor with the same revolutions. When the rotational motion falls or rises, the output of the gasoline generator and the amount of generated current increases or decreases. This is the disadvantage of the classic device, as the wear and tear of the moving elements is inevitable, which leads to a decrease in speed over time.

It is also important for buyers to remember that devices of this type have an additional economic disadvantage. So at low load, which is at a level below the nominal, begins overconsumption of fuel. This point is especially noticeable when a gasoline generator works in this mode for several hours.

What counts as an ordinary portable generator?

Speaking of a portable generator, people usually mean mobile gasoline or diesel generators. These are the most commonly purchased items.

An ordinary portable generator is basically a fuel-powered engine with an alternator that has electrical power. The three most common fuels used for portable generators are gasoline, diesel, and propane.

Some portable generators are hybrids. This means that the engine can run on more than one type of fuel. usually a combination of gasoline and propane.

Engine crankshaft speed and associated electrical power is a key characteristic of a typical portable generator. An ordinary portable fuel generator is rated at 3,600 rpm to generate 120 volts and a frequency of 60 hertz.

However, one of the main disadvantages of most portable fuel-powered generators is that the machine cannot maintain a stable 3600 rpm.

Constant changes in electrical power or high fluctuations are why portable fuel-powered generators don’t provide what’s called “pure electricity”.

Clean power is preferred for sensitive electrical devices such as laptops, cameras, cell phones, etc. д. The inability to hold constant voltage at 3,600 rpm is also the reason why portable fuel-powered generators are so noisy.

In portable fuel-powered generators, there is a relationship between its fuel tank, power, and run time. In most cases, the larger the fuel tank, the greater the power and the longer the run time.

Since some portable generators can produce more than 10,000 watts of power, you can imagine that these are pretty big and heavy generators. Despite their size and weight, most models are still portable. most conventional portable generator models have wheels and a handle.

Inverter generator

The inverter generator has a completely different way of generating electricity, but it is still the same alternating current machine. It does not produce electricity directly, as it does in the classic model. It has several intermediate units in its design, the main one being the battery.

How does the production of electrical alternating current take place??

  • At first it is the same as in the classic apparatus. That is, the internal combustion engine turns the shaft, which is connected to the rotor of the alternator. The latter generates alternating current.
  • The current passes through the power electronics and is converted into direct current. This is how the battery is charged.
  • Now, in order to produce alternating current again, an inverter is installed after the battery, which produces the current of the required voltage, namely, 220 volts at a frequency of 50 Hz.

Why is such a complex circuit necessary, what is its advantage?? Again, it all comes down to the consumption of hydrocarbon fuel. For such a unit there is no need to maintain a constant rotor speed, it can be small enough, and it will be enough to charge the battery. True, reduced rotation will increase charging time. But in this case it is not so important. It turns out that the lower the speed, the less fuel is consumed.

Advantages and differences

Inverter gasoline generators create a stable current of variable frequency, the quality of which is ensured by the built-in microprocessor. The genset works in economy mode, thanks to electronic regulation of the motor speed.

  • Stable output voltage;
  • Preservation of high-precision sensitive equipment;
  • No fuel problems;
  • Low noise effect;
  • Economical fuel consumption;
  • Compact dimensions.

Unlike diesel and conventional gasoline generators, which function on the principles of electromagnetic induction and can not create the necessary current characteristics, they do not need additional voltage regulators.Inverter-type gasoline generators fully provide the full power for the equipment connected to them.

Compact portable power plants are easy to fit in the trunk of a car, they can be transported and connected to work on their own. This is a great advantage over larger gasoline or diesel generator sets.

The inverter module is responsible for the economy of fuel consumption by coordinating the operation of the engine according to the power distribution depending on the load of the power plant. That is, an inverter gasoline generator does not operate at its entire capacity continuously, as other similar stations, but regulates the process, automatically reducing or increasing the speed.

The reduced noise level, thanks to the built-in cover, is another undeniable advantage of the inverter gasoline generators over similar stations. These generators can be installed directly in the workplace.

High degree of protection of power station housing allows placing them even outdoors without the use of a shelter. The machine is not threatened by water and dust inside. Thanks to these qualities, the inverter-type gasoline generator has become popular in the professional and domestic.

Quick overview on power tools. sold in Russia.

Inexpensive household tools that I could recommend for purchase.

Spoiler 1 : no adverts here. All brands are owned by different companies. I am not related to the industry at the moment.

Spoiler 2 : here I am being rebuked in the Комментарии и мнения владельцев. that I am a sofa theorist. That’s not true. I worked in a large trading tool company for 10 years, as I personally sold to customers. I was also the head of sales and purchasing. solved the quality issue, etc. So. Makita has sold over 1 million machines through me or my sales teams. Other than that. by virtue of his position. I had access to sales and statistics on defects throughout the Russian market, I personally visited many factories. manufacturers and RD centers. I’m not arguing that your particular experience with a particular tool. may be different from standard. but I believe. that the law of large numbers often works.

Once again I will emphasize. that part. We are only talking about DIY brands. If you need a tool for WORK. or for a large volume of tasks. better not save money and buy a Bosch / Makita / DeWALT / Hitachi / Metabo. and if finances allow. Milwaukee or Hilti.

Black and Decker. I’ve already mentioned him in passing. This brand belongs to DeWALT. Stanley. It is the only full-fledged global low-cost brand on the Russian market, not an STM. Full relaunch of brand was about 2 years ago, the biggest advantage. the tool is developed by engineers DeWALT. and not just take readymade models from Chinese factories. That’s why there are often a lot of interesting developments and tricks that increase usability. the tool most often has well designed for household tools ergonomics and weighting. tech specs are real. the price is humane, in case of problems with the service, you can always contact the representative office and resolve the issue in your favor. The brand values its reputation.

P.I.T. The first Chinese STM on the Russian market. No in-house production. But it is easier for the Chinese to negotiate with their own countrymen. The distributor is not greedy. the price tag is one of the lowest in the market. The tool is for everyday use. But it doesn’t fall apart in your hands.

Elitech. The brand is owned by Russia’s largest distributor. operating in the market for over 20 years. and distributor including Makita. Thanks to the well-established distribution network. the price is kept at a fairly good level, and the distributor lined service and does not deliver goods with a high percentage of defects. In addition to quite domestic goods. there is a product with a hint of semi-professional.

Patriot. The company is not just trying to order goods from factories. but also to improve it slightly (ergonomics. components. accessories, etc ). It turns out a little more expensive. You can decide if you want to overpay for it or not. The brand has built a good distribution network. That’s why the markups are often reasonable.

Caliber. One of the old-timers of the market. Naturally. All power tools are made in China. The brand is specific. that there is almost everything. that are made in China. The same small angle grinders can easily come from several factories. compete with each other within the brand and be completely different in quality ( which is why there can then be problems with service). For me the brand is interesting first of all because. that there are really unique things. Not imported by others. I would not buy popular categories of products under the Kalibr brand.

Enkor. The brand is famous for its machines. Among which you can find something worthwhile and worthy (just do not buy the cheapest product). as well as not bad household cutters. The tool is ordinary. No better. and not worse than other STM.

Important addendum. When I speak of affordable prices, I mean first of all. That the distributor keeps reasonable. There will always be like those stores. who will broadcast a low price to the customer to increase sales turnover. as well as those of. who decides to earn extra margin.

In the example below we see an example of. when the price of one and the same model varies by almost 1000 and the cost of a peorator less than 3 thousand

Links to previous parts I will not insert, otherwise the bayanometer begins to get angry. they can be found in the profile. Also bayanomomet rightly angry at the word short in the title, took it away 🙂

A Quick Quick Factsheet on Power Tools. sold in Russia.

Judging by the Комментарии и мнения владельцев. Some readers have the impression. That I am against own brands and local brands. Before. How to go further and begin to describe in more detail the remaining local brands, I would like to tell a little more about STM. And, I’ll stress right away. I feel pretty good about private label. Such a tool should be on the market, and for home use it is more than enough. I take it badly that this tool is sometimes sold at triple the price and characterized as professional.

So. The peculiarities of instrumental STM:

A brand can be registered in any country and in any year. It is not very difficult to buy a company in the same Germany, and there to buy an unused brand. registered 10-15 years ago. The price of the question is a few thousand euros. If you want to check the reality of the brand. try to find the official international brand site, and its products can be found on sale in major stores in the home country of the brand. The Internet allows you to do it in a few minutes.

STMs almost never have their own production. They order the power tools almost always in China, because that is where the main production base is concentrated now. Since there are so many large factories in China. specialized in a particular product category ( for example. peorators ), not so much. one plant makes goods for a dozen Russian brands. What is the difference for the customer ? Most often they do not differ in anything except name and price.

STM often do not have a full-fledged engineer on staff. Why? After all, factories are ready to modify tools for a specific customer only if they have very large volumes (which only few can afford). The best known STMs are Dexter. Husky and Cobalt. 2 last are found only in the USA). In other cases the СТМ will not differ from each other. or will differ in small details. or by certain components ( say. chuck. button, etc.)

The range of one STM is ordered from several factories. In other words. large angle grinders can come from one factory and be of good quality. and small. from another plant and be frankly a consumer product. I want to emphasize right away that even different batches of the same model can be produced at different factories. Say. The first drills were ordered from Factory A. But then factory B offered a cheaper price and ordered there. The model won’t change its name.

The Chinese manufacturers themselves, can easily replace some components with cheaper analogs. The customer will then get a 30% defect, but it is almost useless to sue. The bigger the company. the customer. the more prospects the plant sees in it, and the better quality and better he will try to fulfill its order. In addition, as I wrote earlier. The price of goods for CTM will depend very much on the size of the order and the strength of the brand. Because getting an order from a top brand for a manufacturing plant is the best advertising.

Specifications on your tool can be listed ANYWHERE. The factory makes the nameplate according to the customer’s request. The certification bodies in Russia do NOT check the declared characteristics. In addition, some of the specifications can be given as follows. To confuse the consumer. For example, the same screwdrivers always have two maximum torques measured: namely, when screwing into hard and soft material. These values can be very different. With CTM you can only have one torque. highest value. and the value itself can be taken from the ceiling. For example, on a platsik SDS-plus peorator. The warranty is that the machine is a Makita 2470 copied from a Makita 2470 made out of clay and sticks. it could easily be indicated by the impact force of 5 J. even though it is 2.7 J on the Makita itself.

The warranty is. Almost all STMs have entered the warranty race. read its terms and conditions carefully. The declared 5 years warranty may apply only to the housing, or it may be valid only under the conditions of use (as I have seen myself: the time of use of the peorator is not more than 2 minutes in a row. between 2 work intervals you need to let the tool rest for at least 30 minutes), Sometimes it happens. Manufacturer requires that in order to keep the warranty you have to undergo preventive maintenance every six months at the service center. or 5 year warranty consists of 1 year warranty and 4 years free repair ( that means you pay for the parts. and their price includes the cost of repair:).

И. in addition. Let me tell you about so-called “indigenous russian” brands, as well as tools of the former socialist countries.

Now the tools are not produced, except for Fiolent and some Interskol. is not produced ! All other brands. 100% China. Whatever the seller told you. look at the plant-manufacturer. it MUST be on the product or on the packaging. As for Fiolent and Interskol. even in manufactured products. part of components inside the tool is chinese.

Separately, I will tell about Sparky. it is one of the few instrument factories that are still alive and doing well after the collapse of the Soviet Union. The factories are famous for their angle grinders. which, according to the location of the plant and became known as “grinders. At one time ( in the distant 1960s) in Bulgaria was built tool factory. Bought Western equipment and purchased licenses for the models themselves ( yes. angle grinder Sparky first years of production. licensed AEG. which was good at the time). Now the plant produces in addition to the angle grinder almost the entire range of power tools. But of the whole range I can only recommend the angle grinder. polishers and mixers. In other segments there are more interesting options.

Links to previous parts will not be inserted, and then bayanomometer begins to get angry. they can be found in the profile.

I need to tell you about the fraud in the SC and the sales channels themselves ?

Inverter gasoline generator or conventional. what is better to choose?

During operation of a standard gasoline generator, the device generates current, the values of which often do not meet the specified requirements of energy consumers. For this reason the machine is not used in conjunction with ultra-precise machines. The user must constantly monitor the speed to keep it up to speed. This results in high fuel consumption.

Standard alternator generates rough power at the output, while inverter equipment is complete with regulators and inverters. For this reason, the AC voltage becomes constant and the regulator manages to correct the performance. The current is then converted back into alternating voltage, which has a cleaner specification. As a result, the slope of the sinusoid remains within 2.5%. Feedback is used to control the current, so the user is able to apply a stable frequency at a given voltage to power devices. Feedback is responsible for controlling the rotation of the motor, and the current generator is directly connected to the motor.

Another important advantage of the inverter gasoline generator is that the device adjusts to the current load indicator. So if you supply voltage to a single device with 1kW at the maximum power of a gasoline generator of 2kW, the latter enters the mode of operation with half the output. The result will be reduced fuel consumption, and when other devices are connected, the device automatically increases its speed again. The user who prefers an inverter unit can consume only the energy required to run appliances, saving the consumption of expensive fuel.

About standalone generators

Obtaining power in the field or in case of a power line failure is most easily done with an autonomous device. Structurally, it looks quite simple. it is an internal combustion engine, connected to the generator. The engine can be anything. gasoline, diesel, natural gas, 2 or 4 stroke, and designed for a variety of power outputs.

It rotates the rotor of the electric generator and the output is an alternating voltage whose magnitude and characteristics (voltage and frequency) are determined by the characteristics of the engine and generator. The number of windings and the number of windings in the generator during operation does not change. Thus, it turns out that combustion engine operation affects the quality of electricity obtained.

This is expressed by the fact that changing the number of engine crankshaft revolutions leads to changes in the generator output voltage. There is also an opposite relation. increase of load. For example, the inrush current when a new consumer is connected affects the combustion engine and, accordingly, the characteristics of the generated power.

A typical alternator works in this way. The quality of the electricity produced is usually suitable for powering many appliances. The incandescent lamp will shine and at this floating voltage, it will also have little effect on electronic devices, which use a switching power supply. However, there are certain requirements to the parameters of the electrical network 220 V 50 Hz. And many devices are designed for them. And the disruption of the characteristics of electricity leads to failure or premature failure of expensive products.

Comparing the advantages of inverter and conventional household generators

Today the modern industry in the field of electrical engineering offers a lot of different generator equipment, which differs not only in price, but also in the principle by which electricity is generated. Therefore, when it comes to the purchase or rental of mobile generating equipment, many may have a question about this, as well as the desire to compare the advantages of different types of equipment, in this case inverter and conventional generators, built according to the classical scheme.

An ordinary generator with a classical scheme of generating electricity is a device that uses hydrocarbon fuel as the main source of energy, which is mechanically converted into electrical.

Fuel (gas, gasoline, diesel fuel) is used to drive the engine, which is directly connected to the alternator (alternator). Alternator converts the mechanical energy of the engine into electrical energy through a system of permanent magnets and rotor winding.

The quality of the generated electricity directly depends on the stability of the engine, so it must rotate at a constant speed. This is the main disadvantage of this generator design. A conventional alternator can be very inefficient, depending on the mode of operation.

The main problem is the high fuel consumption at partial load, especially when operated for long periods in this mode. This fact should be taken into account, because renting a diesel generator or buying one, in the end, can be very expensive during operation. For this reason it is necessary to select the generator strictly according to the load capacity.

In other words, when you use a rental generator with a capacity of 7 kW in the country or a picnic to watch TV or listen to the music center, you spend a lot of fuel with incredibly low efficiency.

However, the problems are not limited to inefficient fuel consumption alone. There is another problem with conventional generators. Which is the formation of soot in the engine when operating the equipment at part load, leading to premature, irreversible engine failure.

Many manufacturers explicitly indicate in the instruction manual that it is strictly prohibited to load a generator less than 25%, also given is the time during which the generator can operate in such a mode (usually specified hours per year). It should be noted that this is the main reason for a large number of complaints from customers, which boils down to the fact that the household generator works for a year and a half, and then you have to buy a new one (not many people thoroughly study the instructions).

Despite the described disadvantages the generators of the classical scheme of power generation has a distinct advantage, which leaves far behind its more technologically advanced counterparts. This advantage is almost unlimited possibilities in a range of capacities, as well as incredibly high reliability and durability when used at full power and regular maintenance. At the same time the cost of an ordinary generator is much lower than of the inverter generator of the same power.

Features and advantages of the inverter generator

The inverter generator is also an alternator (diesel or gasoline generator), but its principle of power generation is significantly different from the classic scheme. The inverter generator does not produce electricity directly, but accumulates it in the battery, which is built into the design of the device.

The principle of operation of the inverter generator is as follows: first the alternator produces an alternating current of high frequency and converts it into direct current using the power electronics and charges the battery with it. The next step is to convert the battery power into alternating current at a desired voltage and frequency (220 volts/50Hz) with the help of an inverter.

Thanks to this scheme of obtaining electric power the inverter generators are extremely effective in terms of fuel consumption. The whole point is that this generator does not need to maintain a precisely defined engine speed. So it uses much less fuel for smaller loads. It also allows for a lighter and more compact design, since a smaller motor can be used. Another important advantage is practically noiseless operation of the device in comparison with usual generators.

The disadvantages of inverter generators include the price, which is significantly higher than the cost of conventional “classic” generators, as well as the peculiarity of design, which uses a battery installed without the possibility of replacement, and which has a capacity limitation.

The availability of a battery means that short-time connection of high-powered consumers (e.g. a microwave oven) or long-term connection of low-powered devices (e.g. light bulbs or a television set) can only be made to a generator with a battery of the necessary capacity: otherwise, the battery will not have time to recharge. Comfortable use of the “unsuitable” generator is not possible, because there will be a need to turn off the load and wait until the battery is charged again.

What generator to choose?

If there is a need for a constant power supply of high-power devices, then the best solution would be to buy or rent a regular diesel generator.

Also it should be noted that in the range of inverter models there are no devices with power higher than 6 kW. Therefore, if the total power of the connected load is close to or significantly more than this value (for example, an average cottage requires a diesel generator 30 kW), it is better to choose a normal generator with a capacity of. In this case, an uninterrupted power supply will be guaranteed.

If there is an urgent need for power supply of low-power devices and at the same time the mobility of generator is required, as well as low noise characteristics during operation of device, then the inverter generator is an ideal option.

Comparison of the characteristics of generators

Conventional models

  • Wide range of units in terms of capacity.
  • Reliability of generators. This is understandable. the simpler is the construction of any plant, the less problems occur with it.
  • Lower price in comparison with inverter analogues. For example, (depending on the manufacturer and series).

Instability of generated voltage with some (with time) decrease of its nominal value. The main reason is the gradual wear of parts, which is reflected in the rotor speed. It decreases. Therefore, when using a conventional generator, you need to periodically increase the speed, and this is an additional expense of fuel. These models require an optimal load

By the way, few people pay attention to this point, when choosing a generator in a conventional, traditional design. First of all, due to ignorance of the specifics of its work

If you carefully read the manufacturer’s instructions (and practically no one does this either at the point of sale or at home), it becomes clear that all its parameters correspond to certain operating conditions. Specifically, the minimum load is 25%. This is the limit. It is allowed only a few hours a year, that’s all. If it is systematically less, it reduces the useful life of the unit (no repair). And the fuel consumption will be higher than estimated.

For example, if the total power of your consumers on the line is 2,2 kW, and the generator itself has 4 kW, it will consume fuel at the rate of four. That is, almost half of the installation works idle. In practice, this is usually what happens. regular “underloading”.

The accumulation of products of combustion (soot) inside the engine also leads to increased consumption, that is again a problem of premature maintenance and repair.

It turns out that the wrong load on the usual generator is fraught with a whole “package” of problems. So, saving on costs, the owner loses on fuel and parts in the long run. And a part of your free time too. How justified it is, is for you to judge. Especially when you consider that the generator is purchased for systematic (or even continuous) use over many years.

The inverter models

  • Economy. No need to increase the speed of rotation of the engine shaft. It only affects the battery charge time. This leads to an optimised fuel consumption.
  • When changing the load, the output voltage remains constant. This stability is due to the electronic circuit of the converter.
  • Silence. For an inverter generator there is no need to choose a place as for a conventional model. Even installed in the adjoining utility room through a thin partition, it will not disturb the housemates.
  • Compactness and light weight. Inverter generator can be easily reinstalled within the house or plot, transported at a distance (for example, to the cottage). That is, unlike conventional units, these units are mobile.

And what do consumers say??

The Комментарии и мнения владельцев received by the inverter generator are very different. This is partly due to the fact that some people do not consider a certain purpose and specificity of the device: providing fastidious consumers of current with its high-quality variety. the unit is not designed for simple generation of electrical energy. For this there are standard generators. Reviews of specialists about inverter generators are always in the sphere of positive values.

The modern market of electrical equipment currently offers two types of generators, with which, by burning carbon fuel (gasoline, diesel fuel or gas), it is possible to obtain electrical energy. This problem is urgent, because the work of domestic power supply organizations leaves much to be desired. And the periodic disconnection of the electric current supply, the proof of that. So, in this article we will be interested in one question: inverter generator or a regular generator. which is better??

To understand this issue, it is necessary to consider the principle of operation of the two types of generating equipment, the positive and negative sides of design and operation, and pay attention to some positions concerning the economic side of the matter

Results of the review

When choosing an autonomous power supply, it is necessary to consider many factors:

  • operating conditions;
  • The total power consumed by the load;
  • seasonal period of operation of individual elements of the load;
  • the requirements for power sources for household electrical equipment;
  • What kind of fuel for the engine, gasoline, diesel or gas;
  • financial opportunities of the consumer and many other factors.

Separate examples of generator selection:

  • When the power consumption at the site exceeds 6 kW, it makes no sense to count on the use of inverter models. The manufacturers only make generators up to 6 kW. So, you definitely need to install the classic version.
  • In cases of long-term operation, when the load is balanced with the output power of the power supply (power consumption by the load must be equal to the maximum power produced by the generator), the use of a classic version will be more effective.
  • For medical facilities, research laboratories, facilities with communication equipment, where personal computers are used that require a stable power supply, for temporary operation in emergency situations, in the absence of electricity in industrial networks, it is better to use inverter generators.
  • For a private home, in the presence of finances, in the case of prolonged or permanent operation, one of the best options is the division of the load on different power sources.

Generator connection in the switchboard to different groups

Such a connection, separate power sources for different groups of power consumption, suitable for lighting networks, outlets to which are connected computers, TVs, household appliances. They need to supply power with stable parameters, which will provide inverter device.

In the heating system electric “underfloor heating” with a power consumption of 3 kW, which is used seasonally, it is reasonable to install a model of the classical type. The power of such a device should be approximately equal to the load power, this will ensure the optimal mode of its operation, fuel savings and trouble-free operation.

What does the connection of two generators look like?

The inverter unit is connected in the switchboard to the outlet and lighting groups. Classic generators are included on the network of heating cables, for floor heating. It is preferable that the engines of generators run on a single type of fuel, diesel or gasoline.

  • Consumers, for whom the price of generators does not matter, in emergency cases it is better to use the inverter type. This will ensure economical fuel consumption and prevent the breakdown of expensive equipment.

How to buy a gasoline generator correctly

When choosing a generator it is important to properly determine the capacity of your desired unit. Conventionally, they can be divided into three groups according to power:

  • up to 5 kilowatts. Structurally, it is made in a small suitcase that is easy to carry. Such a generator will provide power for household and lighting devices for a short time in the country house, when carrying out repair and construction works, it can be taken on fishing and even in a camping trip;
  • up to 10 kilowatts. Such units are much larger than the previous group and are mounted on wheels. They are used at sites with an average power consumption;
  • Up to 20 kilowatts. Such a unit is able to provide a large object.

The type of load for which the selected genset is intended plays an important role. If it is lighting, household appliances and power tools, then you can use a synchronous generator, if high-tech equipment (computers, computing or video systems, etc.), it is possible to use a synchronous generator.п.). an inverter type generator.

The most popular gasoline generators are: GMGen, Fubag, Prorab, Huter, Honda.
