The grid connection of commercial energy systems in Germany is subject to clearly defined technical and regulatory requirements. Especially for larger installations, battery storage systems, photovoltaic systems, and other energy generators must be integrated in a way that ensures grid stability, controllability, and compliance with applicable standards.
TESVOLT supports specialist partners and project developers in meeting these requirements—with validated interfaces, compatible system architectures, and in-depth technical consulting throughout the entire project lifecycle.
This ensures that battery storage systems can be reliably connected to the power grid and comply with all relevant requirements set by grid operators.
TESVOLT provides a standards-compliant interface for integrating battery storage systems into EZA-controlled installations with the TESVOLT Energy Controller Pro S (TEC Pro S).
The controller connects the higher-level master EZA controller with the TESVOLT battery system and ensures that all control commands are executed correctly.
Connecting large-scale energy systems to the power grid is not just a technical step. It is part of a complex interplay of:
To ensure safe operation, systems must be able to respond to grid signals—for example, requirements related to active power, reactive power, or grid stability.
In Germany, standards such as VDE-AR-N 4110 define the requirements for systems connected to the medium-voltage grid. Above a certain capacity, a central control unit is required to coordinate all generation assets.
This keeps the overall system logic flexible and allows it to be optimally adapted to the requirements of the respective grid operator.
The overall control of complex energy systems is a specialized field in its own right.
Therefore, the master EZA controller is selected on a project-specific basis by system integrators or specialized providers.
TESVOLT focuses on battery storage systems and provides the standards-compliant interface for integrating
No.
The design depends on many factors, such as:
Therefore, the EZA controller is typically dimensioned and configured on a project-specific basis.
The TEC Pro S provides a certified, standards-compliant interface between the EZA controller and the battery system.
It ensures that the grid operator’s control commands are reliably executed and that all functions of the TESVOLT energy management system can be fully utilized.
TESVOLT provides all components required for the integration of the battery storage system. These include:
This ensures that the battery storage system can be technically integrated into the overall system correctly.
The specialist partner is responsible for planning and implementing the overall control of the energy system. This includes in particular:
