Battery storage systems for any requirement

To overcome power supply challenges we can expect in the future, we will need different types of energy storage systems. Infrastructural storage systems compensate for fluctuating purchase and consumption volumes of the electricity generated. Industrial storage systems are often used to compensate for peak loads and thus reducing electricity prices. In addition, industrial storage systems are used as a backup in the event of a power outage. Residential storage systems are often operated in combination with private solar systems. This enables the electricity generated by the photovoltaic system to be consumed and the surplus energy stored in the energy storage system instead of selling the solar electricity to the grid operator at a low rate.

Utility-scale storage systems for grid services

The fluctuating volumes of electricity generated by renewable power generation plants and the expansion of charging infrastructure are posing major challenges for grid operators. Energy storage systems use and store temporary energy surpluses. Electricity is provided when the consumption quantity increases or the generation quantity decreases. Moreover, systems with electrical energy storage prevent power outages, because they allow a power failure to be bridged temporarily.

Energy storage systems in industry

Energy storage systems are used for various purposes in industrial applications. As blackout protection, storage systems can bridge short-term power outages. With it, systems and machines can continue to operate or are properly shut down. Unplanned machine downtime is now a thing of the past. Another important application of an energy storage system is a process referred to as peak shaving, also known as load capping. The storage system provides electricity for peak loads so that it does not have to be drawn from the grid. This has a direct impact on the purchase price and increases the economic efficiency of the system.

Solutions for residential storage

Home energy storage system

If you have a photovoltaic system installed at home, storing the solar power in your own battery storage system is much more economical than selling the solar power at a low rate to the local power provider.  Electrical energy is drawn upon as required and the electricity from the photovoltaic system is used within the household to operate a heat pump or to charge an e-car, for example. Electrical energy generated via the photovoltaic system reduces the amount purchased from the power provider and increases independence from the power grid. In addition, power outages can be bridged with the help of the energy storage system.
