Grid compliance & market readiness everywhere
Comply with international interconnection standards for rapid network connection and seamless operation across regions and grid codes. Flexibly configure for diverse energy and ancillary service markets, with plug-and-play integration to aggregators, optimizers and VPP platforms.

Fast response time with maximum level of accuracy
Fast response time, well under 200 ms, using highly adjustable algorithms like: PID, feed-forward, and filtering.

Steady, reliable, redundant control
Failsafe inverter control with duplicated PPCs and network redundancy for reliable operation and seamless transitions during grid or meter outages.

Secure & compliant architecture
Certified on ISO27001 and ISO27019.
Our solution meets leading cybersecurity standards and supports compliance with NERC CIP, NIS2 and IEC62443, ensuring secure and reliable project operations.

High availability & distributed control
Redundant, fault-tolerant servers ensure minimal downtime through load balancing, active-active failover, clustering, and backup systems. Distributed control with common and individual setpoints, primary-secondary setups, and HV substation control with sub-plant autonomy.

Vendor-independent & universal compatibility
Interoperability through standardized protocols and interfaces enables integration with any device or OEM, supporting IEC 60870, IEC 61850, DNP3, Modbus TCP/RTU, and more. The system is fully adaptable to evolving grid code requirements and plant modifications, with configurable digital and analog I/O.
