Trina Storage launches new BESS solution at Energy Storage Summit EU


Trina Storage, the energy storage arm of major solar PV company Trina Solar, launched its new battery storage solution Elementa 2, to the global market at this year’s Energy Storage Summit EU.

The vertically integrated manufacturer’s new battery energy storage system (BESS) includes the company’s own 306Ah high energy density lithium iron phosphate (LFP) cell, enabling 4,073kWh nominal capacity in a standard 20-foot container.

As with the previous iteration of Elementa, which has been deployed in projects mainly in China and the UK, it is liquid-cooled and is compliant with international certifications, including UL1973 and UL9540A thermal runaway testing.

The company claimed Elementa 2 is highly integrated and flexible, to offer reduced Capex and Opex requirements over the lifetime of the system.

Fire safety components include fire resistant enclosure, and four levels of threat detection including a fire panel with heat and smoke sensors and integration of the Honeywell Li-ion Tamer gas detection technology, and an automatic aerosol-based fire suppression system as standard with an optional water-based suppression system which can also be added.

In an exclusive interview with, to be published in the coming days via ESN Premium, Trina Solar executive president Helena Li said that of more than 4GWh of shipments of the first Elementa since its launch two years ago, the UK has accounted for around 1GWh, in other words the vast majority of installations outside China where the company is headquartered.

Having announced the first commissioned project for Elementa in East England at the Energy Storage Summit in 2022, it made sense to come back for this year’s edition with the new model’s global debut, Li said. It follows a preview late last year at All-Energy Australia.

Additionally, within the UK, Trina Storage has served as system integrator as well as technology provider on most of those projects. Working at that detailed level in one of the world’s leading markets meant Trina Storage picked up a lot of know-how and understanding of what customers want, Helena Li claimed.
