A power outage is a fairly common occurrence in new buildings, old houses, and especially in the private sector. Substations fail, line breakage occurs, safety devices do not withstand. Modern electrical energy storage devices allow you to comfortably and without damage to household appliances to survive these troubles.
Principle of operation
The principle of operation is that in the presence of an external power supply, the inverter transmits voltage to consumers, while the built-in charger in it recharges the battery. When the mains disappears, the inverter instantly switches to battery operation and converts their constant voltage into alternating voltage.
According to their purpose, energy storage devices are divided into 2 categories:
- uninterruptible power supply (UPS) for the operation of home electrical appliances;
- uninterruptible home for the event of a power outage.
Products vary in composition, size, power, cost and duration of the discharge. They can be located both in the building and outside it in separate buildings.
How to choose a battery for home
If turning off the light becomes a permanent occurrence, you should think about purchasing an energy storage device for your home. The battery for the computer does not solve the problem, as it has a limited resource. Devices are needed that can ensure the normal functioning of people for several hours, or better - for a day. Such a technical helping hand will come in handy for large-scale accidents on the line.
The selection criteria are as follows.
- the complexity of installation and commissioning;
- shipping costs and special services;
- resistance to changes in temperature and humidity;
- Efficiency, in modern devices it reaches 98%;
- service life - 5000-10000 m / h;
Uninterruptible power supply SVEN RT-500 - overload capacity (load withstanding when starting the generator) - 200-300%;
- automatic turn-on time - a good energy storage device for the home, when the power is turned off, the conversion process begins in 10 ms;
- ability to work at low loads;
- autonomy - a tank designed for a day of engine operation;
- current quality - high-quality energy storage devices generate current with a deviation from industrial values of not more than 2%;
- the number of charge-discharge cycles - not less than 500;
- capacity - based on consumers with a margin of 30%, but not less than 6 square meters;
- noise generated - inverters operate silently.
Modern high-power electric energy storage devices can provide a house with energy for 1-2 days. When restoring power, they do not need to be turned off, everything happens automatically.
Large home battery
A large Russian-made home battery Ekomotors is an inexpensive and effective analogue to the Tesla PowerWall drive. The product is used for backup power supply of private houses, summer residences, offices and other objects that can be disconnected from electricity at any time. It can also be installed in residential vans, cabins and mobile dining rooms. The device stores energy at low rates at night. It has compact dimensions, mounted on the wall in a vertical or horizontal position.
Specifications:
- capacity - 7.8 kW / h;
- battery voltage - 24 V;
- power - 7.2 kW;
- dimensions - 1000 × 500 × 250 mm;
- weight - 100 kg;
- number of cycles - 7000.
Monitoring the operation and status of the device is carried out using an Android tablet with the ability to display information on a PC or cell phone.
Home Energy Storage
Storage systems for a private house are able to provide power for 24-48 hours. This indicator depends on the completeness of charging, the number of consumers and the battery capacity.
The following battery types are used:
- Lead acid. Inexpensive, hold a charge well and quickly reach full power.
- Li-ion. They are characterized by low weight, low self-discharge and high capacity.
The choice is determined by their own needs and financial capabilities.
Drive device
Electric energy storage devices for houses and summer cottages are a system consisting of two functional units that perform a specific task:
- Battery pack. Designed to store energy from an industrial network, fuel or wind generator, solar panel or water turbine.
- Autonomous inverter. In standby mode, it charges the battery to a predetermined value. In the event of a power failure, it switches to the mode of a DC-to-AC converter (220 V or 380 V), supplying it to the internal housing network.
At the location of the device are divided into built-in, freestanding, floor and wall.
Standard solution and modernization
Depending on the needs and frequency of current shutdown, one or more elements are purchased that are connected in series or in parallel.
To install the structure indoors, it is better to take the AGM and gel models. They are airtight, tolerate full discharge well and do not require maintenance.
Products with liquid electrolyte emit acid fumes that are hazardous to health. They can only be installed outdoors. Such models wear out quickly with frequent discharges.
The company "Ekomotors" is constantly working to improve its products. At the same time, it is produced both commercially and on order.
The client can purchase goods with such upgrades and characteristics:
- power;
- capacity;
- current strength;
- voltage;
- duration of work;
- number of phases.
Based on the changes made, the final price is determined.
The use of energy storage
Household and industrial drives can be used to increase power, uninterruptible power supply in emergency situations and autonomous power supply of objects not connected to the network.
These may be:
- house;
- dacha;
- Cafe;
- workshop;
- slave;
- boiler room;
- water station;
- warehouse;
- garage.
Inverter devices are independent of environmental conditions, but can be recharged from external sources, including during operation.
