Russia is a huge country and every territory of the Russian Federation has its own climatic conditions. It's one thing when you live in the south of Russia, here if I'm cold, then a short and short term. And if you live in the middle band, or in the north - here without the artificial heat you will not live. However, the climate is changing and in the south there are periods when, after an icy rain, there are accidents in the electricity networks and you can remain without electricity for a long time. You can stay without electricity not only in winter, but at any time of the year because of squall wind or hurricane. And while the emergency team will eliminate the malfunctions, dismantle the rubble and splice the torn wires, it will take a long time and not to remain without power for this time, you need to have a backup supply and for the private house this problem can be solved independently. To properly select the right equipment, to choose the right backup power source, you need to consider and consider in detail the situation, which can get the owner of the house.

Reserve source, for how long is it necessary to reserve power supply
Based on the practice, depending on the duration, time, power outage, the terms of the shutdown can be divided into four groups.
Each group has its own peculiarities:
-fast or micro-disconnection of power supply due to short-term voltage drop. Due to the fact that the power supply is turned off for a few seconds or minutes, and then the power is restored, this trip is called micro-trips. Although even a micro-trip can cause the settings of volatile memory in the equipment to malfunction, circulating pumps can be switched off, the burners are switched off in the boilers, the control panel can be turned off by heat generators, etc .;
-because of large overloads on the power lines, fuse-links may burn out, short-term power failure may occur, or they may disconnect the line for short-term work. This shutdown can last from one hour to twelve hours. And these are all short-term outages;
-a short-term outages, there are also medium-term outages. This shutdown is usually in emergency situations, possible due to high voltage power line accidents, due to damage to the high-voltage cable, this happens during excavation. This accident is being tried quickly, but the amount of work is quite large and liquidates the accident within twelve to twenty-four hours;
-The most dangerous is a long-term power outage due to unforeseen natural disasters (power lines and complex transformer substations are massively damaged due to a hurricane, ice rain, flood, etc. The destruction is very large and it takes a very long time to eliminate the consequences of such destruction , up to a month.
The landlord, if he thinks about backup power, must decide on the choice of the desired device, depending on the above situations.
Reserve power supply, which stand-by source of power supply to choose
Choosing a backup source of electricity, it is necessary to take into account for how long the central power supply is turned off.
Let's consider in detail which power source is suitable for each specific case:
-If in your house electricity is turned off for a micro period, i.е. from a few seconds to several minutes, and in the house there is a heating boiler with automatic, a circulation pump, etc., in which case you will be rescued by an elementary uninterruptible power supply with a rechargeable battery. But, this simple uninterruptible power supply will have to hold the load above the equipment listed, at the output this power source must ensure the normal operation of the circulation pump and modern boiler automation;
-if your house falls under short-term outages for up to 12 hours, you need to purchase a system with an uninterruptible power supply and several rechargeable batteries of decent capacity. This backup system must supply power to your equipment for up to 12 hours. The uninterruptible power supply must be able to be charged and fed from external batteries, the total capacity of these batteries should be within 200-400 A / h;
-if your household falls under the medium-term outage (24 -48 hours), a gasoline or diesel generator will come to the rescue. This is more complicated equipment, since it must withstand the work for a long time, it is appropriate to have an emergency transfer unit from the main power to the reserve one, LLC Gesla Phone: 8 (800) 100 19 83, specializes in these units http://gesla.ru;
- If the power supply is often lost for a long period of time, the same gasoline or diesel generator will come to the rescue, but it is necessary to have the necessary fuel stock.
In this case, you can use a backup power scheme in the form of an uninterruptible power supply with a battery and plus the operation of the generator.
This system of backup power supply has an undeniable advantage, since the work is more economical than with a constant power supply from the generator.
Private house backup power project
We recommend, for the correct choice of the source of backup power supply, it is necessary to have a detailed project, which will take into account the total aggregate power of electricity consumers.
When choosing a backup power source, its power is calculated in this way, the total power of the electric consumers is multiplied by 3, because when the reserve power source is started, a short-term power increase occurs several times, which leads to an increase in the starting current.
