Instructions for the organization of backup nutrition of a country house - devices and a diagram. Backup power supply at home: UPS, generator, autorun generator for reserve power supply of a country house

The review may be useful for all kinds of dacms and users of country houses (and may not only be rustic), in places with frequent disconnection of electricity ...


Currently you can buy inverter directly from the factory somewhat cheaper than by the specified link in the review header - the link will be laid below.


Instead of preface
For several years, I moved to the cottage (just like it), and faced the problem of periodic disconnection of electricity. The reasons were put forward a variety of and shortage of power transformer in SNT (knocked out) and a variety of works, etc.
It is clear that these problems did not please me, especially if we take into account that both most daches have water from the well, and when it is turned off the electricity, it simply does not have it: (well, in the cold season, there may be a boiler without a power supply, these all lanterns are tired / Candles ...
He began to look for options for solving this problem.
The first options were the installation of solar panels / windmills (collected info) ... but quite scared the price + payback of this enterprise. Rather, to say such a solution to currently not accessing network electricity at all, while expenses make sense, as commensurable with connecting to network sources. In my case, regular shutdowns for several hours, it turned out too expensive and unprofitable.
The option with benzo and diesel generators was considered (most of the neighbors use a similar option), but has a number of minuses, in comparison with the born idea, use only "part" from the system of home solar energy! Well, i.e. Use instead of solar batteries available network 220V for battery charge, and spend the charge in the absence of the main batteries.
Well, in short, the final version of the scheme turned out to be completely distant from the power scheme solar energy :) But it is much cheaper and easier, and even cheaper even benzo and diesel generators


The scheme successfully worked for more than one year!
Diagram elements
Inverter with UPS and Control / Charging External Battery (In my case, the inverter 1500W (peak 3000W) - in some Chinese sources figured the figure 3000W of the peak load up to 4 minutes, did not check I do not know :) Rather, to say the type of verification (by chance), it turned out, but how correctly it is not necessary to judge to judge - I will describe the details below.

The inverter will be found below in the photo (a neighbor is bought) and mine at 1500W, so they will appear different stickers with power.
Actually overlooked from all sides :)


Front two control shooter indicators (there are modifications) with a 220V network display (on output), level 12B and operation mode indicators (charge / network operation; "Faule" - "Accident" mode This mode is activated briefly when switching and problems in the network, after which it returns to normal; signaling the inverter power on).
It may be worth noting that when the inverter is disconnected through it, the network transmission continues. And one more feature (I would say "jamb") - in the process of work, noticed that the display is 12V, this is not always the battery charge indication. If you make the initial inclusion without the battery at all - 12V will be supplied from the internal converter and therefore the readings will still be 12V, although the battery does not happen. In short, it is from 12V that the indication is not entirely clear , now asked the representative of the plant that he could answer.

This is the supplied kit ...

In theory, everyone chooses the power of the inverter according to its alleged load, I repelled from the average monthly consumption of recalculated, taking into account the possible peak at the time of starting the pump engine. It should be borne in mind that all the electropotters do not make sensebecause A couple of hours you can safely suffer the lack of water heating by heaters, washing, refrigerator (it does not catch off per day)


The smaller the total power, the less power requires an inverter and a smaller battery (at the same time) - this actually allows you to significantly reduce the cost of creating emergency nutrition.


In my case, an inverter is used with a modified sinusoid (it is somewhat cheaper). In the case of a connection (for example) a refrigerator, boilers for heating (pumps, it is necessary to read the documentation) and other devices requiring clean sinusoids (usually there are devices having asynchronous motors) it is necessary to choose the inverter somewhat more expensive, outstanding the "clean sinusoid" (not forgetting about the functions UPS and charge, if you are interested in an automatic transition to emergency food and back).

The pump on the well also "loves" a clean sinusoid, but I proceeded from the fact that he was with a hydroaccumulator (24l tank), and the inclusion in its work is relatively short-term. During this time, the pump does not have time to heat up and go into defense (to the word to say the thermal protection seems to be installed now).
In practice, once the pump went to defense, when the pump was constantly included in the summer (the garden was poured) and the wife did not notice that the emergency food was turned on :) how much time he worked until the protection was unknown :) Special experiments I did not hold.

It is also no need to forget about a very high current passing by 12V, so the connection of the inverter with the battery should be produced very large (it is easy to estimate that in my case it can exceed 100a with full load).
In general, I would advise you to choose an inverter on 24V and squeeze from two batteries (to reduce currents) to users that calculates to use a significant load!

Car battery (I bought with a reserve - for 190 a * h).

As it turned out during operation, this container is too excessive for me - in real life, almost 5 hours of work from the battery, the firmware of the battery voltage meter has not changed noticeably. At the same time, coverage in a pair of rooms, street and two televisions on 24 "and 38", laptop 17 ", (water was needed if necessary) and perhaps something else ... + It was possible to operate with various hand power tools.


Buy special accumulators (whether traction or gel) I decided inappropriate, because The inverter has a battery charge control, and unlike "solar technology" does not produce it below the "normal discharge", and the price is noticeably different.
In confirmation of my assumptions: I did not measure the new (almost sure that when measuring there it would not be 190 a * h, but recently decided to check the residual capacity after the year of use and was pleasantly surprised :)




For a more optimal connection, I divided the entire cottage wiring into two parts (in an electrical box):
- One part goes directly from the network, and is not reserved by an emergency source - water electric heaters, washing machine, refrigerator and other sufficient energy-intensive consumers without which you can easily "live" for several hours.
- The second part is connected from the box through the cable to the ordinary plug, so that, if necessary, it can be included in the existing rosette (inverter and battery easily excluded from the circuit), this may be needed, for example, when the inverter, battery or for their maintenance.
At the same time, the inverter at the output already has a pre-installed outlet standard, to which a plug with consumers requiring backup power is connected.
It happened about it.

Need to keep in mind (on the mind) Some safety technique when choosing a placement and installation (Not quite like mine - it was done rather for testing, but so far it remains, as they say there is nothing more permanent than "temporary" :))

The scheme triggers when 220V (or change the parameters above / below the valid) - switches to power from the battery, with a small noise from the fan of the inverter cooling (depends on the number of consumers connected at the moment) and the display of the operation mode on the front panel is lit. Inverter. When the network appears, it is reverse to the network 220 and the fan noise increases, during the battery recharge time. Almost "jolts" in the house is not noticeable, I do not feel any discomfort from the loss of the network and I can not immediately say (when the neighbors on the TLF call asked) - is there "light" or not :)

Placing a sinusoid, etc. Technical nuances in this review, I consider it optional - because Overview Rather for practical application, rather than studying processes ...
Below the photo inverter's insides.

Comparison of "My" backup power scheme with similar on gasoline and diesel generators:


+ Little cost
+ No Noise
+ No smell
+ Automatic backup power transition
+ There are no problems at launching in no summer in winter (especially relevant when launched by women)
+ There is no need for a separate storage room (and possible use) - on the veranda takes one shelf.
+ there is no need to purchase, bring, store fuel

Limited continuous operation, depends on the load and capacity of the battery.

± controversial items, this is the alteration of wiring and disconnecting some consumers, because You can connect all and remake anything, but it may be necessary to have a more powerful inverter (possibly with a "clean" sine), a capacious battery (most likely the use of two sequentially and inverter to 24V to reduce low-voltage circuits).

Conclusion: quite working scheme, I (and my wife) are at least satisfied well.

As promised, about working with overload.

I left the NG to Peter to friends, and the "guard the farm" remained an adult son. I have a heating of firewood (a furnace with glass, etc. specially put). The son "in the process" could not find a "common language" with her and he lacked heat. As a result, he turned on the oil radiator at 1.5-2kw into the socket, which was powered through the inverter. Well, on the most NG, several hours were interruptions with electricity (then the voltage was ascended, it disappeared and appeared, in short, there were switches).
It obtained the load on my 1500 (3000) inverter 1.5-2kW of the electric heater, light, TV, water pump 800W (when turned on several times excess), light, etc.

Well, a long-term such mockery inverter could not support :) But as it turned out later, only the contacts of the relay were struggling - after replacing everything earned again :)


In the process of "mastering" the circuitry of this inverter, it turned out to "exit" to the manufacturer who kindly provided the scheme-logic to find faults in this inverter.
Posted on your site, because There was no choice of file storage Link to archive

Well, as promised at the beginning of the review Where to buy cheaper such an inverter (and there are others there too) Link to the manufacturerwhich begins to work with shipping for the retail sale of such an inverter and another electronics produced by them. Buying this link is somewhat cheaper, because without intermediaries

Nothing can be worse than turning off the light in winter. Any of the country inhabitants sooner or later faces the situation when the light bulbs are extinguished, the well pump ceases to swing water, and the batteries of the heating system are cooled in front of the eyes. Time to use backup nutrition!

But there is another solution to the problem with electricity interruptions: the backup system of the house or abbreviated - PSA.

To properly select such a power system, it is necessary to understand what it differs from the autonomous power system (SAP).

Andrei Aa, New Moscow.

SRP is used in the case when the main power grid. When the main nutrition is disconnected, the backup power supply "picks up" of the main consumers of electricity: a borehole pump, a boiler, a refrigerator, a computer, TV and other electrical equipment. SAP is the main power supply system for the home used with the complete absence of the main power grid.

Go to the selection of the backup power system. According to Andrey-AA, There are 4 main types of backups for home.

• If the network is turned off for a while, but total per month for more than 10 hours, the optimal will be the system consisting of an inverter, charger, and a block of batteries charged from the network.

The inverter is a direct current converter from batteries into an alternating single-phase voltage of 220V, which runs the equipment in the house.

• If the network is turned off in less than 10 hours per month, then more profitable system from an electric generator with an internal combustion engine (DVS) equipped with an automatic starting system.
• If the network is often disconnected and for a long time, or when the voltage in the network is too low, then the optimal is a system consisting of a generator, a block of batteries, a charger and an inverter.

According to a similar principle, the autonomous power supply systems are also built, but higher capacity requirements are presented to them.

• If the required power can be limited to 1-1.5 kW, then you can use a car with an inverter connected to it as a backup system.

Let us dwell on the third version. User with nickname galexy456.offers a step-by-step plan for creating a budget system for home.

1 Two cables from the utility room are becoming the electric shield. The first cable is necessary to submit electricity to the inverter. The second is to pass electricity from the inverter to the house.

galexy456.

I have a small shield on my street, which implements the automatic reserve entry scheme, or abbreviated ABR

AUR is an automatic switch of one load into two feed lines - the main and backup.

2 In the utility room we set the inverter, batteries and switch all devices.

Inverters are two main types - with sine at the output (optimal option) and with the so-called "modified sine". If the inverter issues a "modified sine", then some devices when connected to it can fail due to high levels of frequency harmonics in the power supply - 150Hz, 250Hz, 350Hz, etc.

In case of turning off the electricity, such a system works as follows. ABR alone and quickly - so that the devices do not have time to disconnect, switches the power from the main on the backup.

Now all connected energy consumers continue to work from batteries and inverter. If the power supply is missing more than 5-6 hours, then, without waiting for a complete discharge of batteries (the service life is strongly reduced), to continue uninterrupted power, it is necessary to manually start the generator.

There are backup power systems with automatic launch of the generator installed in heated utility room and equipped with the forced tap of exhaust gases. The main drawback of such PS is their high price.

galexy456.

After starting the generator, the inverter translates the load on the power supply from it and at the same time begins to charge batteries. Thus, the system of operation of the system is extended and the generator motor is saved, because It works not in constant mode.

It must be remembered that the generator should be run after the use of batteries by approximately 30-60%.

Any, even the most advanced and expensive backup power system, first of all, teaches save energy in the house, because From this directly depends on the operation of the backup power supply system of the house.

Forum users advise:

• replace all the bulbs in the house on energy saving;
• make the second, backup line of the power grid, to which, in case of disconnection of electricity, you can connect the most necessary equipment in the house;
• how to warm the house to reduce heating costs;
• during the operation of the backup system, you do not use powerful electrical appliances: iron, electric kettle, vacuum cleaner.

Andrey-AA

The inclusion of a hair dryer, a kettle or an iron for 3-7 minutes will not defuse the batteries, but ironing or working with powerful power tools is better not allowed.

To build a PSA, the load in the house can be divided into three parts:

1. Heating.
2. Water heating appliances.
3. Instruments requiring mandatory backup power, namely:

• lighting;
• circulating heating pumps;
• borehole pump and pumping station;
• a computer;
• refrigerator, TV, Internet.

Also, a car can also be used as a backup system. For this you need:

1. Purchase an inverter with a sinusoidal output by 12-220 in a capacity of up to 2 kW with overcurrent protection or power.



Users of the site forumhouse can find out how to make a power system yourself. All information on the calculation is collected in this diary. Automatic "From A to Z" is described in this topic.

And in this video, it is described on how the inverter and battery pack can increase the electrical power in the house.

In the work of the power supply of the cottage or country house, power interruptions often occur, especially with a large distance from megalopolises. To ensure autonomous backup power supply, there are many effective efficient devices and schemes that protect consumer equipment and high-tech equipment sensitive to the voltage drops. It is easy to imagine how they feel in the outback of the owners of houses in the cold season when the electricity is disconnected, especially if there is a system of autonomous heating and all electrical appliances. To solve this problem, it is worth installing a backup power supply in the house.

Ways to eliminate interruptions in the electricity supply system

Turning off the power line carries a lot of inconvenience, and to prevent many problems associated with the disconnection of electricity, there are quite a few options. Experts recommend not to deny themselves in all the benefits of civilization, especially since nothing needs to be inventing - the home reserve power supply devices are on sale. They are designed to become an alternative source that will provide electricity in volume, which will ensure the operation of the main electrical appliances for a long time:

• security and fire-fighting systems;
• forced ventilation and air conditioning;
• launch of a solid fuel boiler;
• pumps for water supply and sewerage;
• household electrical appliances and other equipment.

All of them cannot work without a power grid, therefore, an effective backup power supply scheme is so important. Many country buildings do not always guarantee a reliable operation of a centralized supply of electricity. Due to the unstable voltage characteristics on the network and frequent non-planning power outages for several hours, and even days, such systems or sensitive electrical appliances fail. Country house should not be a place for solving constant problems, and an excellent place to relax. Uninterrupted autonomous power supply of the cottage or country householding should function steadily - for the operation of all livelihood systems.

There are several options for solving power interruptions. For example, the installation of an autonomous backup source of uninterrupted type power supply, which can be purchased with the battery kit (batteries). They are capable of working autonomously for some time, depending on their power and total load.

Batteries for a backup power system guarantees uninterrupted supply of consumer electricity with long-lasting network shutdowns or in the absence of external power grids in remote areas.

Project of reserve power supply

The draft reserve power supply includes all documentation where the total capacity of all autonomous sources is taken into account. The system of reserve autonomous energy supply of a country house can also include ultra-modern mini-power stations, and traditional sources of electricity. The more power supply sources are supposed, the greater the effectiveness. However, all indicators of generators and battery capacity should be made to such a project.

The design capacity of autonomous backup power supply, including the inverter, is calculated so - the total power of the working devices is plusing and multiplied by 3. This is caused by the fact that when the technique is started, the maximum amount of energy pulls. This indicator is taken into account in order for the autonomous network to cope with the highest possible load on the design capacity. The calculations include the needs of the power supply to be powered by the diagram:

• active heating (plate and electric kettle, incandescent bulbs);
• inductive (refrigerator, washing machine, TV, microwave, etc.)

Their power consumed is summarized (by table or according to the attached instruction) and add 20-25% of the maximum value, in case all electrical appliances work simultaneously. That is, a small cottage with minimal lighting, a TV and a refrigerator will work according to the backup power supply scheme of a country house with a capacity of 2 kW. If you use the power tools and other devices, then add another 5-6 kW.

Varieties of generators

Today, the most common autonomous backup sources of power supply:

• uninterruptible power station;
• diesel generator;
• wind generator;
• gasoline generator;
• inverter.

1. The gasoline electric generator is considered one of the most efficient, although they won't call it economical. But for it is enough with power consumed about 6 kW. Such energy sources are appropriate where there is no other alternative, and gasoline can be transported without problems. For example, if a country house stands somewhere in the track or not far from the benzocolone.

Main advantages:

• almost silent work;
• well starts in winter;
• can be used as a backup source.

2. In a large home ownership, energy consumption is quite greater, especially if there are many lighting devices and there is no other heating, except for electrocamines. With power consumed, more than 6 kW specialists are recommended to purchase a diesel generator. However, there will not be no significant financial investments here too. But it works practical in any conditions.

3. The wind generator, or in the spacious "windmill", is quite effective, but it can be installed in the area, where quite strong winds are always blowing or pulling seasonal drafts.

4. Among the backup sources of power supply of the new generation are also often used pulsed capacitors (ICE). An excellent alternative to other autonomous power supply systems, practically innovative equipment that can be purchased in the finished form. These portable models offer improved uninterruptible power supply characteristics that can operate autonomously or in a backup power supply system. They suggest such a kit:

• voltage transformer;
• switching relays from the network to the battery;
• charger.

When connecting to the inverter scheme and autonomous batteries, the mini-power station with sufficient power is also obtained.

Inverter system based on solar panels

Worldwide, installation on the roof of solar panels is not new, but the usual thing. The truth is worth it is expensive, but investments pay off at time. The energy of the Sun is easily converted into an alternating current, but it is not enough in each region enough to charge powerful batteries and a full provision of a whole residential building.

In summer, to charge the battery for backup power supply, it may be enough to accumulate it to work in the electric grid in the evening - within a few hours. With a drogh side, such panels are justified when there is a second source of autonomous power supply, such as a diesel generator or an inverter.

The main equipment for working on the energy of the energy of the Sun and the conversion into electricity:

• solar panels mounted on the roof of the house or elsewhere;
• electrical charging controller;
• automatic continuous / alternating current protection;
• set of large capacity batteries;
• inverter unit of the required power.

It turns out a small home power station on the territory of remote large cities of the cottage. It can be supplemented with an effective inverter scheme, where energy sources are designed to effectively complement each other.

The inverter type system is ideal for ensuring uninterrupted power in the complex with solar panels. The generator can be turned off while the battery charges from the energy of the Sun, significantly increasing its life.

Inverter

The inverter is an important component of the autonomous power supply of a country house or cottage. It allows you to periodically disable the generator to minimize fuel costs. Abroad, as an alternative electricity supply scheme, inverters are considered an integral part of the autonomous power supply. They are universal and in the case when there is no way to use the energy of the wind and the sun.

This apparatus is supernamed, functions according to the scheme "Inclined and Forget". Modern inverters guarantee uninterrupted backup power not only real estate objects, but also the "mobile" housing type trailers, yachts and auto trailers, etc.

To protect against power supply when the electricity is disconnected, an inverter is well coped to the backup power supply of the house. At voltage of 220V, it is capable of providing the supply of electricity, with minimal service costs. At the same time, it provides the ability to connect batteries that give a long reserve supply with electricity. Inverters refer to the line of the most enduring UPS to use domestic electrical appliances and sensitive to voltage changes.

Important inverter advantages:

• silent functioning;
• the possibility of installation in any room;
• minimum care and maintenance;
• high reliability;
• long-term manufacturer's warranty;
• excellent quality;
• stable supply of electricity;
• automatic transition with connecting to a backup power supply scheme.

The inverter when the power is turned off the power line on the street or in the settlement until the day - out of competition. Uninterrupted cottage or country area power supply using the inverter with a frequent disconnection is more profitable to work with the generator.

Tip: as an option - Generator plus inverter. Here they are summarized by their "pluses" and "minuses" are leveled. The inverter is capable of running the generator if batteries are discharged, and then turn off without need. The generator is noise, so it is advisable to include it during the day, while being at work or outside the house, and in the evening go to the silent inverter.

Features of the electric generator

Electrical generators work on different sources of energy and produce:

• 1-phase current - for powering devices by 220 W;
• 3-phase current - by 380 W.

The generator for reserve power supply is very effective, and its power can exceed 16 kW, so it is quite suitable for the full autonomous support of the country house. As an option - to support uninterrupted power, with frequent electricity shutdowns.

Open execution generator comes with:

• automatic ventilation system;
• shield to ensure work;
• system of exhaust gas
• module automatic fuel refueling;
• automatic flame extinguishing system (fire fighting measures).

Cons of the generator:

Without changing filters, candles and oil, the generator fails, as well as it is required:

• ventilation room;
• canisters for transporting diesel fuel or high-quality winter diesel engineering to work in the cold season;
• background noise and claims of neighbors in inconsistent inclusions;
• the smell of the processed diesel fuel;
• the need for periodic rewinding, refueling and controlling work;
• compliance with the schedule for replacing consumables.

Although these problems are not so much to abandon its use, but it disrupts peace and a normal holiday in a country house. And although it guarantees backup power supply and uninterrupted food at home, it is better to use it in a complex with other systems and in the absence of home.

It is for this reason that diesel electrical generators are most often used as a reserve source of supply of electricity. Today, the domestic market offers a lot of varieties of diesel generators used for backup power supply of country houses, as well as for heating and supplying water. Modern diesel power plants go in the modular and classic (open) option.

With the need to organize backup power facing almost every country property owner. And there are several reasons for this: the worniness of communications, intensive development in the neighborhood, the inconsistency of the substation characteristics of the increased needs and a number of others. This causes systematic (sometimes long) to disconnect the voltage, its constant throws or phase skews. The problem is familiar to many.

In such conditions, it is not that we are talking about the guaranteed period of operation of various (and sometimes very expensive) household appliances; Many of them do not turn on at all. For example, an imported gas boiler, which is quite popular from "private traders", is very demanding of the quality of the voltage. "Overseas inventors" and in the head can not come that with electricity there are such misunderstandings. And if the defense works and it will "rise", in winter, with our frosts, then this is the most present state of emergency.

With the feasibility of power supply redundancy, everything is clear. But how best to do it and what to take into account, we will look at detail.

Here is meant, for what period it is necessary to organize an independent power supply of the site. Some devices are designed for long-term continuous operation (, water-cooled gasoline engines), others require a systematic stop (the same gasoline with air cooling).

By the way, some specialized firms offer connectivity services directly to LPP (bypassing the local substation). Sometimes it is simply impossible to organize an energy supply in a different way. To do this, use or cable laid in the trench, or an air line stretched to the site. If this organization has an appropriate license, and it takes on all concerns about the design of permits, then this is an excellent option.

The disadvantage is the cost of work, as you have to install your own substation. Although there is a way out - "cooperate" with neighbors who experience the same inconvenience in power supply. But there is a tangible "plus" - the stress interruptions are excluded, and its quality will meet all regulations.

What devices need to be "powered"

Approximate power

From this will depend on the further criteria for selecting the source of energy. It should be navigate, naturally, on those that should work constantly. For example, the same boiler, refrigerator, freezer. Each owner must compile a list of all products that must be constantly included.

Type of voltage

Most residential units consume 1-phase 220 V. But there are also those necessary for 3 f. It must be taken into account if they are also constantly used. But such products are quite rare.

Power source

According to experts, it is necessary to navigate the maximum of 20 kW. For a country house (if it is not a palace, with various devices) is quite enough. But this is for the option "all inclusive." Perhaps enough aggregate and 4 kW. For example, if the boiler (along with the pump), a refrigerator and TV + lighting will be operated at the same time, then no more than 2-2.5 kW will be needed. If the water supply system is autonomous, then the pumping station will be turned on periodically. Its power also needs to be considered.

In addition, it is necessary to take into account that some household appliances are characterized by a large launcher. For example, the electromazor is exceeded with a nominal value of 6 to 7 times. In addition, there must be a calculation to the perspective. Perhaps something will be purchased yet, and also with mandatory constant inclusion. It is necessary to make "stock" for the generator itself, as it should not work at the limit. Optimal loading - no more than 80%.

Summarize. As you can see, there are quite a few nuances. Therefore, all the "products" should be defined (including the lighting devices on the adjacent territory, automation, signaling, and the like), which should be provided with uninterrupted power at any time and calculate their cumulative power. The resulting value must be multiplied by 1.5. That is the parameter and select power installation.

Type of fuel

It can be gas, diesel fuel (solarium), gasoline. Everyone determines himself, with which it is more convenient (and cheaper) to work.

Place Installation

It defines both the size of the power supply and its design features. For example, diesel more smokes, so high-quality "extract" is necessary. Ungregates without casing - "noisy", therefore, they are more suitable for accommodating in housekeeping (extensions).

If it is provided for the installation of a backup unit on the street, then you need to pay attention to the way it is launched (manual or automatic, from AKB).

Features of backup power sources

Gas generators

If the house is gasified, then this is the most optimal option. Fuel for such a device is the cheapest. The power of most such products begins from 7 kW, which is quite enough for a country house with periodic disappearance of voltage in the network.

Approximate cost - 180,000 rubles. But if you consider how much it will be saved on fuel (compared to gasoline or solarium) for the entire period of operation, the price is quite acceptable. In addition, there are almost no harmful exhaust.

Benzogenerators

The most common type of device for backup email. In part, this is because we are better dealing in exactly such engines than in diesel. After all, many owners of country houses have a personal car, therefore, at least a general concept about the principle of operation. In addition, they are easier to maintain.

Diesel units

Under this name is meant several types of similar "techniques" - diesel generators, diesel stations, and so on. Indelible dignity - the possibility of long-term (without stopping) operation. In addition, there are no gasoline vapors that require special fire safety measures.

We have brought only the most common devices for organizing reservations. But there are a number of others that, although applied less often, but also worthy of attention. For example, UPS, solar panels, systems in inverters.

Output

Practice shows that regardless of how to solve the problem of reserving the power supply system, it is necessary to have a spare generator. According to the reviews of most owners of country houses, more comfortable both from the point of view of operation and repair are gasoline aggregates. For example, they can always be removed directly from the car's tank.

Solving the organization of reserve power supply, should not be guided by someone's opinion, focus on friends or neighbors. The main "tip" is its own home and property in it (first of all, technical devices and the location of lighting devices). They determine the feasibility of acquiring a particular unit.

It is necessary to consider that the UPS, the solar panels have limited use in both time and by connected devices (diagrams). Their kit includes AKB, and they require constant attention (monitoring condition, recharging). In addition, modern batteries (in contrast to the "old" models in which individual banks could be replaced) is not subject to repair.

In the presence of funds, it is advisable to mount a more complex, but reliable combined redundancy scheme. For example, the inclusion of emergency nutrition from the UPS followed by automatic launch of the diesel engine. This is more expensive, but the power supply interruptions are excluded.

To create uninterrupted electricity supply and organization of a highly efficient heating system, it is necessary to buy an UPS for home (uninterruptible power supply for home). There are several types of uninterruptible diet blocks for home, which differ in their work.

Purpose UPS for home

The main purpose of the UPS for the house is considered to be the supply of electricity of residential premises when it is turned off or emergency de-energization of the center line. When you receive a voltage to the main network line of the UPS for a private house in automatic mode, power supply again, the power supply can occur all consumers or selectively. Data of uninterruptible diet for home is equipped with special protection against voltage fluctuations in the network and allow it to stabilize it.

UPS types for home

1. Backup uninterruptible power supply for home - the price of the device is distinguished by affordable. High efficiency is guaranteed, but the heat transfer is small. The shortcomings include slow down switching from the power supply on the battery, low-quality input and output filters from interference, turning off the power supply at small voltage jumps.
2. Linear interactive BP source - switching fast with automatic voltage control mode on the network. You can already buy such a uninterruptible at home at a higher price, since all its blocks and nodes are made of high-quality material.
