Munich, Nov 18, 2025 – Trina Storage, the global leading energy storage solution provider, today announced the launch of Elementa Electra, an advanced integrated battery-to-grid energy storage solution designed for large-scale renewable and storage applications. As an AC-coupled BESS solution, Elementa Electra integrates the battery system with an AC-side unit that combines power conversion and medium-voltage step-up functions — enabling efficient power conversion, more coordinated performance between DC and AC subsystems and streamlined grid connection.
Built on Trina Storage’s vertical and horizontal integration capabilities - spanning in-house cell R&D, system-level integration, and localized engineering and services, Elementa Electra further strengthens the company’s full-stack approach to energy storage. By pairing the long-duration battery cabinet with the integrated AC-side power conversion unit, Elementa Electra provides high-energy density, long lifecycle performance, optimized DC-side design, and grid-forming AC-side functionality in a seamless, deployment-ready platform optimized for operational value.
“As the electrification of end-use energy continues to accelerate, energy storage has become essential for balancing renewable supply, improving grid reliability, and supporting the transition to cleaner power systems,” said Mr. Yang Bao, President of Energy Storage Division at Trinasolar. “With Elementa Electra, we are extending our innovation to the AC domain — delivering a fully integrated, battery-to-grid solution that enhances system efficiency, grid stability, and long-term reliability for our global customers.”
Ultimate Reliability
The system is engineered with a robust control architecture that enhances operational stability and long-term performance. Comprehensive fault self-diagnosis and dynamic tiered fault protection enable safer system operation, while advanced islanding detection maintains stable operation under changing grid conditions. With seamless transitions between operating modes, Elementa Electra provides strong operational flexibility and consistent, reliable performance.
Rapid Delivery
With 25 GWh of annual system production capacity across two manufacturing bases, Trina Storage delivers factory-tested, pre-commissioned systems that reduce site work and accelerate deployment. Elementa Electra is optimized for whole-unit transportation, which significantly reduces logistics costs. The compact side-by-side/back-to-back station layout reduces required land area by up to 52%, while factory pre-commissioning cuts on-site commissioning time by more than 50%, shortening overall delivery cycles by over 30%, helping customers achieve earlier grid connection and faster revenue realization.
Superior After-Sales Service
Supported by four R&D centers and global integration & engineering centers, Trina Storage has established a comprehensive service network, providing customized full lifecycle services from project consultation and design to installation, operation, and maintenance. Paired with an AI fault monitoring system, it enables 24/7 risk warning and digital-intelligent collaborative after-sales support.
In addition, Elementa Electra is actively undergoing comprehensive certification processes to meet the cybersecurity and grid-connection requirements of major markets, including compliance with Europe’s leading network and information security regulations. Designed for global deployment, it meets the technical and grid interconnection standards of diverse regions, ensuring reliability, interoperability, and long-term operational assurance.
The Elementa Electra solution enables turnkey project delivery within 80 days and supports long-term service agreements (LTSA) with warranties of up to 20 years, guaranteeing high asset availability and stable returns for customers.
By combining in-house battery technology with purpose-built power conversion, Trina Storage delivers holistic control of the entire BESS stack—from cells to AC-side integration—enabling tighter performance optimization and stronger cost efficiency. This integrated approach makes Elementa Electra a flexible, high-performance platform for applications such as renewable shifting, frequency regulation, grid forming, and black start, while supporting more competitive project economics for utility-scale deployments. The solution reinforces Trina Storage’s cell-to-system capabilities and accelerates the build-out of resilient, low-carbon energy infrastructure worldwide.
