The challenge
Compliance has never been harder
EV charging is booming — but so is regulatory pressure.
In the DACH region, staying compliant is no longer optional: German standards like VDE-AR-N 4100, 4105, and 4110 require controllable devices like EV chargers to be grid-integrated and curtailment-ready. Austria’s TOR rules add equally strict requirements. And with 850+ Distribution Network Operators (DNOs) in Germany alone, each with its own "Technische Anschlussregeln" (TAR), Charge Point Operators face a maze of specifications.
For CPOs, this means:
Rollout delays due to fragmented technical rules
Increased engineering & connection costs
Risk of non-compliance blocking new sites

The lack of standardization slows roll-out and puts scaling ambitions at risk.
The Solution
Our service: Grid Control
This innovative service leverages our GATEWAY local controller, included in our new FLEXBOX. It ensures seamless communication between your EV charging infrastructure and Distribution Network Operators (DNOs).
Here’s how it works:

GATEWAY Integration
The GATEWAY local controller, which is a key element of the NETBOX, is deployed at your charging site, providing a secure and reliable interface for DNOs to manage load limits. It supports multiple communication protocols, such as DNP3, IEC 61850, and Modbus, ensuring compatibility with various DNO setups.
Real-Time Load Management
During periods of high grid demand, DNOs can remotely adjust the power consumption of your EV chargers to prevent grid overloads. The Gateway Connect receives commands from the DNO and dynamically reduces the power drawn from your chargers, ensuring continued operation without risking grid stability
Automatic Compliance
The Grid Control service automatically adapts to the specific requirements of each DNO, ensuring that your operations remain compliant with all regional grid regulations. This reduces the complexity of managing different technical standards across multiple sites.
Effortless Scaling
Whether you’re managing a single site or a network of charging stations, our Grid Operator service scales effortlessly, allowing you to maintain consistent, compliant operations as you expand.
