Power Electronics Secures JC Star‑1 Certification, Strengthening Cybersecurity for Energy Storage Systems in Japan

A New Benchmark for Digital Security in Japan’s Energy Transition 

Japan is accelerating the deployment of renewable energy and large‑scale storage systems, driving the need for advanced cybersecurity protocols, secure digital communication, and grid‑resilient equipment. In this context, JC Star‑1 Certification represents the most stringent local standard for cybersecurity compliance, ensuring that connected devices meet the requirements defined by Japanese authorities and utilities. 

By obtaining this certification, Power Electronics confirms that its solutions are fully prepared to safeguard critical infrastructure, guaranteeing operational continuity and data integrity in increasingly digitalized environments. 

Growing Presence: 23 BESS Projects Supporting Japan’s Grid Evolution 

Power Electronics continues expanding its footprint in Japan with a fast‑growing portfolio of 23 Battery Energy Storage System projects—10 already delivered and 13 scheduled for completion before September. This strong deployment momentum highlights the company’s long‑term commitment to the Japanese market and its alignment with local technical and regulatory expectations. 

Cutting‑Edge Technology for Stable and Secure Operations 

The company’s PCSK battery inverter stands out as a modular, high‑availability solution designed for utility‑scale applications. Featuring up to four Field Replaceable Units (FRUs), it enables rapid on‑site maintenance and minimizes downtime. Its advanced grid-forming capabilities support frequency stability and ensure consistent performance across Japan’s diverse grid conditions. 

Complementary solutions such as the MV Skid Compact streamline installation by reducing civil works, while the DC/DC converter enables DC‑Link hybrid architectures that maximize PV utilization in areas with export constraints. 

Meet Power Electronics at Smart Energy Week Tokyo 2026 

Power Electronics will present its latest storage and hybridization technologies—including the PCSK and DC/DC converter—at Smart Energy Week Tokyo, held from 17 to 19 March 2026 at Tokyo Big Sight, Booth E11‑50. Technical, applications and business development specialists will be available to discuss the company’s solutions and support stakeholders in advancing Japan’s next generation of BESS projects.
