Trina launches 5 MWh energy storage system

Chinese PV giant Trina Solar has introduced a 5 MWh energy storage system across strategic regions including Europe, Asia-Pacific, and the Middle East & Africa.

Dubbed Elementa 2 Pro 5 MWh, the system uses 314 Ah cells with a 15,000-cycle lifespan.

“The Elementa 2 Pro utilizes EV-grade cells that undergo rigorous abuse testing to ensure intrinsic safety,” the company said. “A triple-layer electrical protection system, combined with an emergency stop function, provides comprehensive safety across the cabinet, power conversion system (PCS), and energy management system (EMS), guaranteeing stable operation in diverse environments.”

The systems are IP55 and IP67-rated and come in a standard 20-foot cube container setup, with dimensions of 6,058 mm x 2,896 mm x 2,438 mm and a weight of 40.5 tons.

The batteries use liquid cooling and can work at ambient temperatures between -30 C and 55 C. They can also work at altitudes of up to 2,000 meters. Typical operational duration is 2-8 h.

“Its compact side-by-side and back-to-back design significantly reduces footprint, addressing space constraints in urban and industrial environments,” Trina said. “Additionally, state-of-the-art noise reduction technology lowers operational noise to just 70 dB, making it an ideal choice for noise-sensitive locations.”
