Electricity storage is a modern solution that allows you to store the collected electricity and use it later. They allow you to manage energy better and reduce costs. How are energy storage built and what parameters should you pay attention to when looking for the right solution?

How is an electricity storage facility constructed?
Energy storage devices used today are made of several basic components. Although specific models may differ in detail, the core is usually similar.
One of the basic elements are modules responsible for storing energy. Currently, various variants are used, which differ in the technology used. Among the most commonly used are lithium-ion, lead-acid, sodium-sulfur batteries, but also supercapacitors, water tanks, or compressed air storage.
Each warehouse also has battery management systems. Their task is to monitor the status of the warehouse, i.e. parameters defining the battery charge level, warehouse temperature, voltage and current. Constant control of parameters protects electricity warehouses from overheating, damage and excessive discharge. An efficiently operating energy storage system allows for the optimization of the warehouse operation, improving its efficiency and service life.
The next element are inverters, or so-called inverters, responsible for converting direct current, which is in the batteries, to alternating current. If energy storage for photovoltaics is used to collect energy from the network, then the principle of operation is reversed and the alternating current is converted to direct current.
Due to the nature of the device, proper and efficient cooling systems are also necessary. They are the ones that make it possible to manage the temperature and maintain its stable and optimal level. Passive or active cooling allows you to keep the batteries in good condition for a longer period of time.
The individual elements are enclosed in a fitted casing that protects the interior from mechanical damage and difficult weather conditions and moisture. The whole is equipped with appropriate safety systems, protecting against fire and overvoltage, among other things.
Additionally, communication and control systems are used in energy storage facilities. Modern technologies allow for remote and convenient monitoring of storage parameters and its integration with other appropriate systems. An example of this would be renewable energy sources, such as wind turbines or photovoltaic installations.
What parameters should you pay attention to when selecting an energy storage device?
The possibility of storing energy is a very practical solution, but for the device to actually fulfill its role, its parameters must be adapted to the needs of the installation. How to choose an energy storage? It is best to pay attention to the following parameters before buying:
- energy storage capacity (expressed in kWh);
- rated power (kW);
- battery type;
- energy efficiency;
- depth of discharge;
- charge and discharge time;
- service life (number of charging cycles);
- operating temperature;
- size and weight;
- type of battery management system.
It is worth considering the potential for expansion if it turns out in the future that energy needs are greater. Expanding an existing system may be more beneficial than replacing it with a new, larger electricity storage facility.
Energy storage facilities at the Onninen wholesaler
Onninen offers various energy storage variants, so you can choose a model tailored to your needs, e.g. a photovoltaic installation. An example is the V-TAC VESTWOODS energy storage . A low-voltage model with a capacity of 5.12 kWh, with a lithium battery. A big advantage is the large number of charge/discharge cycles, because according to the manufacturer, it is as many as 6,000 cycles.
Another solution is a proposal from VOLT Polska — the VOLT ULTRA energy storage . It is ideal for photovoltaics. It allows you to store energy and then release it when the installation does not produce the appropriate amount of energy, and the demand for energy exceeds the current ability to produce energy by photovoltaics. The VOLT ULTRA home energy storage is equipped with lithium-iron-phosphate batteries, thanks to which the device will operate efficiently for a long period of time.
The offer also includes solutions such as the V-TAC VESTWOODS energy storage . V-TAC provides a 10-year manufacturer's warranty for the device, which is a great advantage on the one hand, and certainly a sign of quality on the other. A low-voltage model with a capacity of 14.33 kWh, characterized by a high number of charge/discharge cycles (up to 6,000). The device is ready for wall mounting. A great advantage is the possibility of monitoring using a dedicated application.
