Launch: New power conversion system for energy storage takes center stage at the smarter-E Europe 2025

At the 2025 smarter-E Conference in Munich, I was happy to be part of the unveiling of our latest innovation in battery energy storage technology - the liquid-cooled and high-power density Power Conversion System (PCS). Exhibition attendees even had the opportunity to get a firsthand look at this next-generation PCS by visiting our booth, where we showcased a life-size model of one complete power module from the new converter.

As energy systems worldwide shift toward electrification and decarbonization, innovative power electronic solutions like our new converter are emerging as the unsung heroes of the modern grid. Power converters have a vital role to play in the energy transition by enabling grid flexibility, stabilizing intermittent renewables, and unlocking value in the expanding Battery Energy Storage System (BESS) market. Thats why the continued development of solutions designed to make renewable integration faster, more reliable, and more efficient are so important.

Built on a Solid Foundation

Evolving from our trusted central converter line, this PCS brings forward reliability and performance that’s already been proven in the field. Backed by more than 30 years of Hitachi Energy’s BESS field experience, this converter is engineered for dependable performance in the harshest and most dynamic grid environments, for example in Chile’s Antofagasta desert.  

Leveraging this experience towards creating a unified platform approach to design and manufacturing simplifies the supply chain, reduces engineering overhead, and supports consistency for developers, battery OEMs, and integrators. This solid technological foundation ensures that our solutions not only connect renewables to the grid but also provide the flexibility needed to respond to a global array of application requirements.

Designed for What's Next

Engineered to thrive in the modern energy ecosystem, our PCS levels up flexibility and intelligence. Modular and adaptive, this converter meets evolving performance standards and diverse use cases enabling us to address the needs of system integrators and project developers as well as utilities and end users. And when enhanced by Hitachi Energy’s wider digital offering, the PCS brings advanced digital features like remote diagnostics, cybersecurity, and seamless cloud integration that all work together to future-proof the system for long-term value.

Modular, Scalable, Ready

Built to scale, this converter also supports a wide array of applications and adapts to strict regulatory landscapes across both performance and market requirements.

Whether it’s a standalone installation or a multi-site deployment, the PCS ensures broad applicability and consistent performance. In parallel in BESS, hybrid systems, or emerging energy hubs like hydrogen, our converter delivers reliable performance across use cases and has been developed, built and tested on the same hardware and unified control backbone. This flexibility in both product and portfolio allows us to serve the diverse needs of our customers effectively as well as rapidly.

A Key Piece of the MV Package

As part of a medium voltage package, this converter plays a central role by integrating various technologies and its fully integrated liquid-cooled design boosts power density to ensure stable reliable performance even in challenging environments. This technological integration highlights the power of connection, bringing together different elements to create a robust and flexible solution.

Hitachi value multiplied

Leveraging the entire Hitachi value chain, our solution maximizes system-level benefits through integrated technologies. From transformers to in-house developed advanced control systems, this solution taps into the strength of the entire Hitachi value chain. With high design margins and field-tested architecture, the new PCS reduces failures and maintenance, ensuring a better total cost of ownership. These flexible solutions meet the needs of system integrators, developers, utilities, and end users, and illustrate our commitment to leveraging the full force of Hitachi to drive the energy transition and deliver a more sustainable, electrified energy future.

Hitachi Energy's power conversion portfolio is designed to streamline the integration of renewables and energy storage systems, making the transition to a sustainable energy system faster and more efficient. Our solutions offer value stacking through system integration, providing flexibility, resiliency, and enhanced grid strength. Key features include noise level management, grid compliance, and proven performance in harsh environments. With a leading global service footprint, advanced modeling capabilities, robust cybersecurity measures, and efficient lead times, our portfolio is equipped to meet the demands of the evolving energy landscape.

By leveraging these features, Hitachi Energy positions itself as a key player in the global transition to sustainable energy.
