Reserve power supply country house It remains a topical question at any time. Many owners of private country houses Faced with situations when electricity suddenly disappears. The correct solution of this problem is to provide electricity at home due to the organization of backup power.
The autonomous power supply system can ensure the uninterrupted operation of the entire equipment of the house. In case of a failure of a stationary power grid, the backup power supply will be able to provide the necessary power supply to the operation. Power supplies that provide an independent power supply to the main supply of the house are different between themselves and are presented in a wide variety.
To ensure the electricity of a private country house with an unplanned disconnection of energy often apply:
The main function of modern sources of backup power supply of the house is the implementation of uninterrupted supply of the house with electricity.
Backup uninterruptible power supply performs the following functions:
When the values \u200b\u200bof the supply system have critical parameters or electricity is absolutely no, the automation connects the inverter, which takes the current from the rechargeable battery.
For generator engines need:
From the correctness of the selected equipment for the backup power supply system of the house depends the duration and quality of devices. Suitable for the choice of the backup source of electrical power should be responsible.
For a private house, the following devices usually choose:
Modern backup uninterrupted power supply of a private house is possible with solar panels. The battery system is an eco-friendly method of producing electrical energy to power the network. Elements solar battery Consist of photovoltaic modules that are covered with glass. This glass has a defined texture and allows you to absorb a lot of sunlight.
The wind generator can be used as an electricity source only in the territory where there is a wind. Now this source of energy is rarely used as a backup power supply of the country house due to the conditions unfavorable for the work.
Gas generator power plants for electricity supply
Gas generator power plants can work on natural and liquefied gas. They are connected to K. gas system. The cost of these power supply sources is usually significantly lower than other generators.
Gas generator power plants have:
Most often, the power plants are designed for uninterrupted long-term operation in authorship with the ability to control remotely. Harmful emissions from these devices are less.
The benzenerator is used to generate electrical power of low power and can work for a while. These sources are with an air and water cooling system.
Gasoline Autonomous Generator:
The benzogenerator is often used to power private houses where there is not long-wire supply with electricity from the main power grid. For long work, it does not fit.
The diesel generator is more powerful and depending on constructive features It may be designed for a long work.
It is supplied:
However, a diesel generator, like gasoline, discarded when working harmful products Combustion and creates a lot of noise when generating electricity. This requires the adoption of various technical measures in order to reduce adverse effects.
In the work of the power supply of a private house often, power supply interruptions often. To ensure the autonomous operation of power supply to date, many different devices and equipment are offered, but one can make an alternative source of power supply on its own, which is not so difficult.
You need to purchase an inverter and perform the following actions:
A large selection of backup power sources of various power allows you to choose the most optimal power supply system for use in country house. So that the power grid is reliable, you need to consider various nuances Both when creating a project and when installing. In addition, it must be remembered that the system should be safe.
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 go out, borehole pump It 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.
For right choice Such a system must be understood as 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.
The inverter is a direct current converter from batteries into an alternating single-phase voltage of 220V, which runs the equipment in the house.
According to a similar principle, the autonomous power supply systems are also built, but higher capacity requirements are presented to them.
Let us dwell on the third version. User with nickname galexy456.offer step-by-step plan creating a budget backup 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 instruments when connected to it can fail due to high level Harmonic frequency in nutrition - 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.

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:
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:
Also, a car can also be used as a backup system. For this you need:
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.
To create uninterrupted power supply and high-efficiency organization 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.
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.
All uninterruptible power sources for home differ in the type of execution.
If the UPS is low-power, then small batteries are located together with the inverter and the charger. The advantage of the models is small-sized and mobility, and the disadvantage - the replacement of the batteries should be produced to similar, which are rarely found on sale.
UPS with an external battery - batteries can be easily moved to the room with a constant temperature, since the battery does not withstand the temperature fluctuations.
All uninterruptible power sources for a private house contain certain blocks:
Work uninterrupted source Nutrition for the house lies in such actions:
In order to properly choose uninterrupted food for a private house, you must add all the power used devices and add 20%. So you can get the maximum power consumed. Even if not all appliances At the same time turn on, it is still better to select uninterruptants for the house with a reserve for the future.
When the UPS is installed in the house for all consumers, it is not necessary to purchase a separate uninterrupted boiler. The UPS price is quite high, so not everyone can buy uninterrupted home. In such cases, you can purchase the UPS specifically for gas boiler. When purchasing it is necessary to follow the above criteria, as well as to pay attention to the capacity consumed by the boiler and pump.
Cottages and cottage owners are often faced with power failures. The system of reserve power supply of a country house will be helped to solve this problem. They will protect high-tech equipment, household appliances and any electrical appliances from stopping work and breakage.
Today, uninterruptible power supply stations on batteries, gasoline, wind and diesel generators are used as a backup power supply system.
Uninterrupted systems based on Bineos inverters are considered universal equipment. Such backup food of the cottage works according to the "Switch on and Forget" scheme.
Gasoline models have a small power. As a result, the number of devices that can withstand such an aggregate is minimal. Another minus is the problems when overheating the engine. Gasoline generators for the cottage have a small period of continuous operation.
Diesel devices are sufficiently noisy, so their installation in the house and recreation areas is not recommended. They are distinguished by high cost and large service costs. In winter, launch a generator working on a diesel engine is very difficult, as the fuel thickens.
The company "Light on" offers backup power supply and uninterrupted food at home through an inverter and ankb, which is more profitable and reliable acquisition than a regular generator for giving!
Periodic shutdowns of electricity are able to deal with the entire heating system and affect household appliances. Organization of backup food at home only at first glance is a difficult task. In this article we will tell you how to independently organize a backup power supply at home.
Virtually any farming, you can find a number of devices that would be nice to provide backup power. Here you can attribute a refrigerator, waterproof equipment, heating boiler, computers and telephony devices. Suddenly interrupted power supply or voltage jumps reduce the operation of the engines, it is possible to fail the power supply units of electronic devices.
There are two ways to reduce the influence of the urban power grid on the rhythm of their life. To do this, use or uninterruptible power supplies (UPS), or emergency electrical generators.
Almost all modern desktop computers Equipped with uninterruptible power supplies to protect against data loss. Similar to the device devices, but more powerful class, can be used to feed home appliances during emergency de-energization. The specifics of their use extends to the organization of battery storage facilities capable of providing the entire electricity house within one to two days.
And yet, the most widely used by the UPS, protecting a separate consumer or several, combined into a selected line, to which boiler or duty lighting can also be connected. This is radically changing the power plan of the house, it may be necessary to lay an additional wiring.
Inverter uninterruptible power supply system: 1 - network; 2 - battery inverter; 3 - rechargeable bank; 4 - consumers
Before the acquisition of the UPS, you should draw up a list of emergency consumers and calculate their power consumed for the longest period to which energy is possible. At the same time, it is necessarily taken into account both the mode of operation of the equipment and past idle experiments without electricity.
For example, in reserve nutrition need:
Thus, it is possible to determine the overall consumption of instruments: 2.4 + 2.28 + 2.04 + 0.8 \u003d 7.52 kW / h per day. To take into account and compensate for the temporary degradation of UPS batteries, it is necessary to add 30% to this value, as a result, the necessary daily capacity of the UPS battery will be almost 9.8 kW / h. Making an amendment for the time of emergency work, you will receive the necessary power of the device. Consider that the devices of this class of power are very expensive and make an additional power supply not always needed: because the UPS will not work under full load, the calculated container is enough completely.
If necessary, organize backup power to one or two consumers, it is reasonable to use local UPSs. So the alteration of wiring in the house does not need, you only need to correctly select the place of installation of the device, and it is quite cumbersome.
In general, with a load over 3 kv / h, it makes sense to set one backup power device for all consumers by organizing a dedicated line for them. Purchase of one powerful UPS is more profitable for several less powerful, in this case the cost of installing new wiring is fully justified.
Another plus of high-power UPS is the ability to independently determine the mode and characteristics of the output current for longer autonomous work. The built-in charge controller in such devices significantly extends the life of the batteries and maintains them in full readiness even during long downtime. Most devices have a communication interface with a PC to track the log log and diagnostics, and the built-in voltage stabilizer will exclude voltage jumps and network interference.
There are two ways to increase battery life: increasing the park of batteries and the use of an autonomous source of electricity. The first option is more expensive and use it only in those conditions where the installation of the FEF generator is impossible, for example, in apartments or offices. A controversial question arises: why do IPS need a generator?
Practice shows that parallel use of these devices has its advantages:
In some cases it makes sense to use generators with autorun function. At the time of passing to power from the emergency generator and in case of abnormal situations (the ruling generator, the fuel is over), the power switches to the UPS. In the normal mode of the generated electricity, it will be enough to support the full charge of batteries and the inclusion of all consumers to work.
Hybrid uninterruptible power supply system: 1 - network; 2 - inverter; 3 - generator; 4 - rechargeable bank; 5 - consumers
Comfort from the use of the UPS is quite high so that many owners think about the backup nutrition of the entire power grid, and not individual consumers. For this, there are also several ways to solve.
If it is impossible to install the generator, the reserve power function takes the assembly of sufficient capacity batteries. The type of battery is determined by the mode of operation: heliums have the highest cyclicality and are designed for frequent inclusions, lead-acid AGM batteries are cheaper, they are optimally used to work in bypass mode.
The rechargeable park is assembled from several parallel connected maintenance-free batteries with a capacity of 100-200 A / h. The total capacity of the park must correspond to the general power consumption in terms of low voltage, that is, in the consumption of devices from the 230 V, the consumption of instruments from the network 230 V was 9.8 kW / h or kva / h. At a voltage of 12 V, this is equivalent to a total consumption of 816 A / h, so determines the total capacity of the park. When assembling, it is also necessary to take into account the own energy consumption of the system and losses in low voltage wires, this is approximately 5-7% of the initial power. All functions for managing uninterrupted nutrition takes over the inverter with electronically control. The cost of a proper quality device (Meanwell) per 1 kW of peak power is 400-600 $, from 3 to 5 kW - 1200-1400 $. By the way, comprehensive devices with the same parameters cost at least 2-3 times more expensive.
Backup system with AVR block: 1 - network; 2 - generator; 3 - rechargeable bank; 4 - automatic reserve entry shield (AVR); 5 - multifunctional inverter; 6 - consumers
If there is a generator, the battery park can be significantly reduced to one or two hours of uninterrupted work. But it will be necessary to install the AUR device with the generator startup function. The simplest shields are suitable. domestic production, such as GHMPG-3-1-50 "Techenergo" (~ 20,000 rubles) or assembly of ABR independent execution.
