Power Electronics Achieves JC Star-1 Certification, Meeting Cybersecurity Requirements for Japanese Energy Infrastructure

Power Electronics, a global leader in inverter products for photovoltaic and energy storage systems, has obtained the JC Star‑1 certification, confirming compliance with the highest cybersecurity standards required for equipment connected to Japan's power grid.

This certification underscores the company's active efforts in the Japanese market and its commitment to providing solutions that offer high levels of safety, reliability, and operability for the rapidly evolving energy environment.

New Standards for Digital Security Supporting Japan's Energy Transition In Japan, the introduction of renewable energy and large-scale energy storage systems is accelerating, leading to a rapidly growing demand for power equipment that ensures advanced cybersecurity measures, reliable digital communication, and robust operability.

Against this backdrop, the JC Star‑1 certification guarantees compliance with the most stringent cybersecurity standards set by Japanese regulatory bodies and power companies.

With this certification, Power Electronics has proven that its solutions appropriately address the cybersecurity requirements of critical infrastructure, ensuring operational continuity and communication reliability even in an increasingly digitalized environment.

23 BESS Projects Supporting Japan's Grid Evolution Power Electronics is also expanding its business scale within Japan, currently deploying a total of 23 Battery Energy Storage System (BESS) projects.

- 10 projects have already been delivered - An additional 13 deliveries are scheduled by September

These delivery achievements demonstrate the company's long-term commitment to the Japanese market by reliably meeting its technical and regulatory requirements.

Cutting-Edge Technology for Reliable Plant Operations The company's PCSK battery inverters offer high reliability and operability based on a modular concept optimized for grid interconnection.

- Composed of up to four Field Replaceable Units (FRUs), allowing for quick on-site replacement in case of failure - Minimizes downtime and maintains highly reliable operation - Enhances frequency stability with advanced grid-forming capabilities - Delivers superior performance tailored to Japan's diverse grid conditions across different regions

The utilization of MV Skid Compact facilitates plant design and minimizes civil engineering work, leading to shorter construction periods. Furthermore, in areas with output restrictions for solar power plants, the co-location of storage systems with DC/DC converters enables a DC-linked hybrid configuration, thereby resolving generation losses.
