The PV Supernode controller offers advanced energy storage control functions, enabling precise management of energy flows between the photovoltaic installation, the energy storage system, local loads, and the power grid. The system dynamically adapts storage operation to changing market conditions, the facility’s consumption profile, and grid operator requirements, supporting energy efficiency, reduction of operating costs, and stable integration of renewable energy sources.

Energy storage control enables optimal management of energy charging and discharging processes, increased self-consumption, loss reduction, and active response to changes in energy prices and power grid operating conditions.

The system uses historical data, real-time measurements, and market signals to forecast energy demand and the availability of renewable generation. Based on this, it automatically controls charging and discharging processes of the energy storage system, performing energy arbitrage and optimizing costs in real time. Full automation of energy management processes allows dynamic adjustment of consumption and production to changing conditions such as energy prices, facility load profiles, and current availability of renewable energy—without the need for manual operator intervention.
