The effectiveness of energy storage systems is very important for today’s energy systems, especially taking into account the growing sources of renewable energy. Such solutions for energy storage allow the energy supply and its demand to be matched more reliably, hence wind and solar energy can be easily integrated. Thanks to modern technologies, energy storage systems are designed in such a way that energy is not wasted but is used right when and where it is needed most, thereby lowering the cost of operation. Continuous research and quality development allows us maintaining a strong position in this market as a manufacturer of energy storage systems which are able to satisfy customer requirements in different regions.
