The Karlsruhe Institute of Technology developed and installed an innovative AC-linked pilot storage system at KIT Campus North together with industry partners. Surplus solar energy can be stored in the li-ion batteries and therefore is available at times of peak load and at night. The KIT-developed central control unit (CCU) represents the higher automation level for long-term and strategic energy flow control, taking into account external variables. The system is self-sufficiently controlled depending on the operator’s load profile and measured system data, and the CCU ensures a smooth operation of the system in order to maximize battery performance.

System components: PV system of 37 kWp with DC/AC converter, one li-ion battery of 25 kWh, central control unit (CCU), bidirectional DC/AC converter of 30 kW

Due to its modular design the capacity of the storage system
is expandable.
