Trina Storage's Landmark Project in Japan

Trina Storage, a leading provider of energy storage products and solutions, has recently achieved a significant milestone by introducing its first large-scale industrial battery, the Elementa 2, at two power generation facilities in Gunma Prefecture, Japan. The project concluded successfully on June 4, 2025, after thorough adjustments at both locations.

This ambitious initiative marks Trina Storage's first delivery of a grid-connected storage system specifically designed for the Japanese market. The Elementa 2 units consist of a fully integrated storage solution that prioritizes safety, energy efficiency, and ease of maintenance. These systems fully comply with Japan's high voltage requirements and are adaptable to various electricity trading systems, including wholesale and demand response markets.

Innovative System Integration

The Elementa 2 follows an advanced system integration model, covering everything from battery cell manufacturing to power supply systems. The newly installed systems include critical components such as battery containers that house self-developed and manufactured battery cells. Furthermore, Trina Storage provides comprehensive long-term operation and maintenance services over a 20-year period. This ensures quick and accurate responses to customer needs while enhancing operational efficiency through stable parallel operations.

Insights from Trina Solar Japan’s Leadership

Li Na, president of Trina Solar Japan, expressed enthusiasm about the simultaneous delivery of two systems in this initial project. She noted the engineering team's exceptional preparation, enabling them to complete all processes—including installation, trial operation, and grid interconnection—in under three weeks. This achievement is a testament to Trina Storage's locally-driven capabilities and reliability. Li Na thanked the customers for their trust and cooperation, promising continued efforts toward promoting clean energy in Japan through innovative technology and strong service.
