New Control Options for Residential and Commercial Photovoltaic Systems

KOSTAL and PPC have implemented an advanced connection between the inverter and the CLS device, offering a pioneering expansion of control options for residential and commercial photovoltaic systems. With the latest software update (V. 3.04.01) for the KOSTAL PLENTICORE G3 in combination with the "CLS Adapter" from Power Plus Communications AG, customers can now meet the requirements of §14a EnWG and §9 EEG of German law. By implementing the use cases "Limiting the Power Consumption from the Grid" (LPC) and "Limiting the Power Feed-In to the Grid" (LPP), this represents a significant optimization for the smart control of energy networks.

Together with the KOSTAL Smart Energy Meter G2 (from firmware version 2.5.0) and the KOSTAL ENECTOR Wallbox, convenient functions for limiting grid consumption (LPC) can now be implemented. These innovations prepare KOSTAL users for the requirements of the Energy Industry Act (EnWG), which came into effect in Germany on January 1, 2024, by ensuring compliance with the conditions for digital power curtailment.

KOSTAL and PPC: Ready for Future Challenges

§14a of the German Energy Industry Act (EnWG) and §9 of the German Renewable Energy Act (EEG) establish key regulations for the flexible control of electricity consumers and generators. §14a EnWG aims to ensure that controllable consumption devices such as electric vehicles, heat pumps, and home storage systems operate in a grid-friendly manner to prevent grid overloads.

§9 EEG mandates that operators of decentralized generation systems, such as photovoltaic installations, reduce their feed-in power during grid overloads. With KOSTAL's new features, these legal requirements are fully met. The solutions enable system operators to manage energy flows flexibly and respond to grid requests in real time, which is crucial for maintaining grid stability.

The PPC "CLS Adapter" serves as a link between the grid operator and the customer’s system. By utilizing EEBUS-based communication, the customer system can be integrated securely and interoperably. Additionally, the digital control provides feedback to grid operators and energy suppliers.

Implementing Regulations Efficiently and User-Friendly


With the integration of the PPC "CLS Adapter" and KOSTAL’s innovative inverters and wallboxes, customers are well-prepared for future energy management requirements. These solutions facilitate efficient and user-friendly grid integration by enabling a flexible and automated adjustment of energy flows.

"Thanks to these future-proof solutions, our customers can keep pace with new regulations while maximizing the energy efficiency of their systems," says Dennis Hollenbeck, Product Manager for Energy Management at KOSTAL. "The intelligent combination of the PLENTICORE G3, the Smart Energy Meter G2, and our ENECTOR Wallbox ensures that our customers remain prepared for technological and regulatory changes in the long run."

With these innovative solutions, KOSTAL not only addresses current regulatory requirements in Germany but also lays the foundation for the future of digital energy distribution. "With this partnership and interoperability validation, we are driving forward the digitalization of the energy transition. We are enabling an intelligent and secure connection between customer installations, grid operators, and market participants," says Julian Zilg, Deputy Team Lead for CLS Products at PPC.
