Energy storage systems as the storage medium for renewable energy

Energy storage systems enable the self-consumption of renewable energy, regardless of when it is generated. They therefore make a significant contribution to alleviating the load on power grids and support the integration of renewable energy into the power grid. Special connection technology optimized for use in storage systems is required to connect these storage systems quickly, safely, and efficiently.

Industrial storage
Energy storage devices have long been used in commercial buildings and factories to provide an uninterruptible power supply. New technologies extend the range of possible applications in energy management. For example, using energy storage devices to cap peak loads significantly reduces energy costs for companies.
Industrial storage
Utility-scale storage
Utility-scale storage systems are used to support the grid. For example, they allow high peak loads at fast charging stations for electric vehicles despite inadequate grid infrastructure. Another use of utility-scale storage systems is in the energy trade, i.e., the storage and provision of energy depending on the price of electricity.
Utility-scale storage
Residential storage
Coupled with a photovoltaic system, energy storage devices play a huge role in homes. The proportion of self-generated electrical energy used in the household’s own electricity consumption is increased significantly and continuous autonomous supply is possible in the event of a malfunction in the public grid.
