Inverter generator or conventional generator - which is better? Difference between inverter and conventional generator

Sometimes situations arise when electricity is urgently needed, but it has been turned off, or there is no way to connect to the network. For these cases, a special generator has been created to supply energy. Designs of this type are presented in a wide range. This could be an inverter gas generator. There are also petrol models.

Features of inverter generators

The portable inverter power station generates stable voltage due to the built-in microprocessor. You can connect it to the mains. This device is an inverter type generator. To understand how an inverter generator differs from a conventional one, you need to understand the classification of such equipment. Such units are divided into several options:

1. Gasoline. Used on construction sites and in domestic conditions. Operate from 4 to 8 hours continuously, after which the engine must be cooled. This is the answer to the question of what a gasoline inverter generator is and on what principles it works.

2. Diesel. They act as an emergency power source. Designed for long and intensive use. The engine is designed in a special way and includes a liquid cooling system. That is why the operation of this device can be continuous.

3. Gas. The most environmentally friendly and economical option. The device runs on liquefied gas cylinders. It can also be connected to the main line. When connected to a central water supply, an inverter generator provides a constant supply of energy.

Basic operating principles

To determine what an inverter generator means, you need to understand why it is used. The key difference between such a device and a standard one is the ability to produce perfectly clean voltage. The point is that a simple generator set provides a crude electrical signal. Not all household devices can adapt to it. Inverter device designed so that its operation involves a converter and a voltage regulator. They work simultaneously.

As soon as the engine is turned on, alternating current is supplied to the converter. Due to this, it becomes permanent. After this, the specified value is processed by the regulator. It levels all indicators to normal levels. The energy thus obtained is again transferred to the converter, where it takes on the role of alternating current. The electrical current at the output point is controlled by a feedback circuit. It is also responsible for engine speed, while a regular one is simply connected to the motor.

Inverter units also differ from standard devices in that, thanks to a microcontroller, they can adapt to the current load. For example, if you need to service a household appliance with a power of 1 kW today, while the device itself is designed to supply 2 kW, the installation automatically reduces the operating power by half. This allows you to reduce fuel consumption.

Launch type. Manual generators start with a certain effort, and this is not always possible from the first turn.

Similar models with automation successfully cope with this task and do not cause any inconvenience.

Inverter generators. What are they needed for? Their features and advantages. 24.06.2014

What are inverter generators?
Inverters are devices with a gasoline, diesel or gas fuel system that make it possible to convert, using a semiconductor rectifier, the input 220 V AC network current into 12 V DC, and after smoothing out its ripples with capacitive filters, transform back the DC voltage current into an AC current with specified parameters on the load . Due to this conversion method, it is possible to obtain an output electrical signal characterized by high voltage and current accuracy.
These devices are generators of periodic voltage, which in shape is most often as close as possible to a regular sinusoid. Theoretically, they allow you to obtain an output current that has any necessary parameters that do not depend on the input voltage. In this case, it is possible to obtain not static current parameters, but adjustable current parameters of various frequencies and voltages. A constant voltage of 12 V is generated by the supplied batteries.

What are inverters used for?
One of the most popular ways to use an inverter is to use it as an emergency or backup source of electricity to power household appliances and devices that consume 220 V AC. Most often they are used to connect kitchen and office equipment, a TV, a refrigerator, as well as high-frequency equipment in a country house or country house when the power is suddenly turned off. Depending on the total power of the load connected to it, this equipment will be able to work autonomously for at least several hours. Also, with the help of inverter stations, power tools (power saws, drills, planers) are connected for carrying out repair and construction work in places where there is no 220 V supply. Such units are no less in demand among fishermen and hunters.

Basically, inverter stations are designed for occasional operation during spontaneous power outages. They are purchased once and last for many years. The long service life is explained by the reliability of the mechanism of these devices, ensured by the following factors:
the presence of a special ignition system at the heart of these devices, which guarantees quick start of the inverter;
control of devices using an automatic control system, which contributes to economical fuel consumption, the indicators of which are reduced by 40%.

Two types of inverter power plants
Depending on the shape of the output signal, these devices are divided into two groups that differ in cost. The first includes units with a pure sinusoidal output voltage, the second includes devices that provide a simplified output signal (trapezoidal sine).

Which inverters are better: pure or modified sine wave?
The advantages of models characterized by pure sinusoidal voltage are:
1. extremely low harmonic distortion of the output current waveform;
2. ensuring faster operation of inductive motors included in microwave ovens and other household appliances, due to which this equipment heats up less;
3. lower level of “noise” in devices such as audio amplifiers, game consoles, faxes, fluorescent lamps, hair dryers, etc.;
4. reducing the likelihood of personal computers freezing, fewer errors when printing;
5. more reliable operation of the following types of household, office and other equipment that are not able to function normally when powered by voltage from a modified sinusoid;
6. laptop computers;
7. laser printers and other copying equipment, magneto-optical disk drives;
8. digital clock;
9. sewing machines, characterized by variable speed motors;
10. equipment with microprocessor control;
11. fluorescent lamps;
12. some medical devices (such as, for example, oxygen concentrators);
13. transistor-based power tools with variable rotation speed;
14. charging devices for cordless power tools.

From inverter generators, the output signal of which is a modified sine wave, most modern electrical equipment is able to function normally. Therefore, if you are faced with the task of providing autonomous power supply to standard household electrical appliances, such as a refrigerator, TV, lighting lamps, etc., then the most optimal and economical solution would be an inverter that generates a modified sine wave, and it is better to choose models with “pure sine” for more sensitive equipment.

Basic operating modes of inverters:
1. Long-term operation: provides for the operation of the inverter at rated power levels.
2. Overload mode: most of these units allow operation for no more than 30 minutes at maximum power, the value of which can be 1.5 times higher than the rated power. Such a large but short-term overload can occur when the refrigerator is turned on.
3. Start-up mode: within a few milliseconds, the power plant releases increased instantaneous power necessary to ensure the normal start of the device and overcome capacitive loads.

Which is better to choose an inverter or a generator?
Many users will quite rightly note that it is quite possible to use a conventional generator to organize independent power supply for electrical equipment. However, devices with an inverter system have a number of advantages, including almost silent operation, light weight and small dimensions, which is very important when used in domestic conditions. In addition, inverters do not contain moving parts in their design, which makes them more reliable and does not require periodic maintenance. In autonomous power supply systems for large facilities (for example, large cottages), inverter stations are often used in conjunction with an additional generator designed to charge batteries and increase battery life.

Advantages of inverter generators
The most important advantages of inverters are their wide capabilities, expressed in the conversion of electric current, as well as their high speed. Due to this, they are rightfully considered the best sources of independent power for welding equipment. In addition, they are perfectly compatible with a wide range of electrical appliances. These devices are equally suitable for household appliances, power tools and electronic equipment. Thanks to the replacement of bulky electromechanical circuits with semiconductor boards, it was possible to achieve the most compact dimensions of inverters, as well as significantly reduce their weight compared to transformer generators and semi-automatic devices.
The use of more modern element base and automation could not but affect the price of such devices in the direction of its increase compared to units made according to the classical design. But, despite this, the benefits that inverter generators provide, consisting of greater opportunities in terms of current conversion, efficiency and mobility, are much more important than one-time savings. In addition, the maintenance of such power plants is much simpler, not as costly and labor-intensive as that of analogues of other types, due to the absence of an electromechanical part in them. Consolidating all of the above, the most significant advantages provided by inverter power plants can be characterized by the following theses:

lightness, compactness and mobility (according to these indicators, they are several times superior to other types of generators), which allows them to be considered portable sources of autonomous electricity;
high efficiency due to accurate calculation of engine speed in accordance with the applied load;
silent operation due to the presence of a double soundproof housing and special mufflers;
the presence of models operating on bottled fuels (diesel fuel, gasoline), which is very convenient and practical;
high reliability and durability, which was achieved through excellent adaptability and resistance of internal parts and connections to external loads, as well as adverse factors affecting the external environment;
generating electricity of the highest quality.

Summing up
The features and advantages of generators with an inverter circuit listed in this article allow us to confidently declare the high functional, technical, as well as operational characteristics and performance of this equipment. In this connection, their use in educational and medical institutions, offices, private homes and country houses is absolutely justified to ensure the autonomous operation of household appliances, computing and multimedia equipment, security alarms, power tools, production devices and other equipment that requires a constant supply of electricity. .
Inverters are valued because they are able to generate adequate quality electricity to power the above-mentioned equipment, ensuring their safe operation. Once you buy such a device, you will once and for all forget about the problems of spontaneous power outages, surges and drops in mains voltage. In addition, the long service life of inverter stations helps to minimize the funds spent on repair work or the purchase of a new generator. Do not forget that in most cases, for the vast majority of household appliances, supplying voltage with a simplified form of the electrical signal is quite sufficient, and the “correct” sine wave is important only for high-precision telecommunications, laboratory, measuring, medical and various professional equipment (HI-FI, HI -END audio and video equipment).

The difficulties of country life and construction are often associated with ensuring uninterrupted power supply. These problems, as a rule, have to be solved by purchasing an autonomous power source - a generator. The purchase of complex equipment is justified not only in cases of problems with a stable supply of electricity. A backup power source may be needed completely unexpectedly. And then, even in the event of a sudden power outage, the main systems of the house continue to function.

At the moment, there is such a variety of models and options of generators on the market that it is really difficult to figure out which one is suitable for solving a particular problem.First you need to decide how much power the house consumes. It is clear that each homeowner will have his own figure. On average, a country house needs at least 10-15 kW to maintain supply systems. A small country house or change house consumes 2.5-5 kW.

It is much more difficult to determine, without experience of use, which type of generator to choose: inverter, regular gasoline or diesel.
Let's look at the pros and cons of each option.

Conventional generators.
Essentially, it's a small power plant in your garage - fuel is burned, the engine turns a generator, mechanical energy is converted into electrical energy.
Pros:

Large selection of generators of different capacities. From “crumbs” of 1 kW to serious machines of 8-10 kW or giants of 20-40-100 kW, intended for industrial use.
Ease of use and relative reliability subject to operating conditions.
Low price compared to inverter analogues. On average, the cost of a 4.5 kW generator will range from 25-45 thousand rubles.

Minuses:

The generator must operate at a constant load. Using a generator with a load of less than 25% leads to its premature failure.
High fuel consumption at partial load.
Noise when the engine is running. A working generator should be located as far as possible from living quarters or in a soundproof box.

In such generators, the quality of the generated electricity directly depends on the optimal load chosen for the engine - it must rotate at a constant speed. That is, the main problem of such machines is not frequent breakdowns, as users sometimes complain, but illiterate use.When the generator is operating at rated powerand with regular maintenance it will serve for many years without complaints. Another problem that may arise when using such a generator is changes in the output voltage when the engine speed increases or decreases. For home lighting and some appliances, small changes in voltage are not critical, but for some expensive systems - refrigerators, circulation pumps, smart home systems or gas boiler controllers, any change in power quality can lead to equipment failure or premature breakdown.

When choosing a generator, you need to pay attention to the additional capabilities of modern models:

a protection system for critically low oil levels, which automatically stops the engine if the oil level is below the minimum.
overload protection system that will turn off the generator in time
voltmeter to monitor output voltage
wheels for transportation

Inverter generators.

The operating principle of an inverter generator differs from the classical scheme in that electricity is not supplied directly to the network. First, when fuel is burned, high-frequency alternating current is produced, then it is converted to direct current and accumulated in the battery.

Pros:

Stable characteristics of generated electricity.
Reduced fuel consumption, since there is no need to constantly operate the engine at a certain speed. As the load decreases, fuel consumption also decreases proportionally.
Inverter generators are always more compact than conventional generators of similar power. This allows you to use them not only permanently in country houses, but also to take it with you on a picnic or fishing.
Inverter generators are almost silent.

Minuses:

High cost of the generator. On average, a 3.5 kW generator will cost more than 50 thousand rubles, while a regular gasoline generator of the same power will cost about 20-30 thousand rubles.
The structural complexity of the inverter unit and the impossibility of its element-by-element repair, only replacement as an assembly.
Power restrictions. Inverter generators with a capacity of more than 6 kW are not found.

An inverter generator will be an ideal solution for providing uninterrupted power supply to sensitive devices that are afraid of voltage surges: heating boilers, laptop chargers, computers, and complex electronic equipment.

That is, it turns out that if there is a need to constantly provide electricity to premises, buildings, construction sites, and to solve the problem of emergency lighting, then it makes sense to consider a conventional diesel or gasoline generator. Working at full load, it will last a long time and will not require repairs or additional investments for a long time. Timely oil changes and the use of high-quality fuel increase the service life of the generator.

In case of emergency power supply to a residential building, literally crammed with electrical appliances, it is better to use inverter-type generators. Replacing and repairing numerous equipment that burned out due to a sudden power surge will cost more than the most expensive generator.

If you need to solve both problems at the same time, then you can choose a combined option, using both inverter and conventional generators at the same time. The plot, lighting of the garage, house and bathhouse can be provided with energy using a conventional generator, for example. this model is 6.5 kW.

But the heating boiler, complex kitchen appliances, it is better to connect the pump in the well to an inverter-type generator, which can be chosen from several 3.5 kW models, such as this

or 2.5 kW, which can be viewed at link.

The operating principle of the inverter generator is based on the use of an inverter system. It primarily involves pulse width modulation control, which is capable of producing very good quality electricity. All this became possible thanks to the adjusted output voltage with a stable frequency.

The operation of an inverter generator begins with the operation of a rectifier, which generates direct current from alternating current. Next, the pulsation is purified, which is stabilized by special filters. Then alternating current begins to appear in the bridge circuit with the help of transistors, as well as special switches. Some power plants additionally use thyristors. Output current parameters are controlled in all areas. As a result, the frequency will always be stable. The parameters of the feedback circuits are controlled by the inverter generator system.

Internal organization

The multipolar inverter type generator consists of two parts. The first block includes a rotor with a three-phase network, which acts as a permanent magnet in the system and additionally has a stator. The second part of the multipolar generator is called the inverter block. It consists of a rectifier, a filter, and a converting circuit that produces an alternating voltage. The process is monitored by a microcomputer.

Generator operation

When the generator starts, the rotor immediately begins to quickly gain speed. Rotation occurs directly near the stator. As a result, three-phase alternating current is generated. Next, it is sent to the inverter unit, where it passes through a rectification circuit, which equalizes the voltage and stabilizes its output. The converting circuit makes the voltage sinusoidal. As a result, alternating current is output from the inverter unit. The microcomputer is responsible for the current frequency signal and provides voltage parameters.

Inverter generator: reviews and benefits

Inverter gasoline power plants have a number of advantages. First of all, this is saving resources. The ignition system installed in inverter generators can significantly save fuel. This happens thanks to a well-thought-out control system that is fully automated. As the load on the generator increases, the engine speed will increase. When the loads are small, the power plant reduces speed and decreases. As a result, the economical mode can protect the system from overloading the inverter generator. Reviews about this function are only positive.

The second advantage of inverter generators is the type of connection between the system and the engine. Direct connection to the generator motor eliminates the need for additional installation of a flywheel. Ultimately, this affects the weight and size of the power plant. Without a flywheel, the generator weighs significantly less, which makes it easier to transport, and the small size of the device allows it to be installed almost anywhere.

All modern inverter-based gasoline power plants have an air-cooled engine. Thanks to it, the motor can withstand heavy loads for a long time. The noise reduction casing allows the inverter generator to be installed in close proximity to people.
