TrinaStorage’s Elementa 3 series ESS, featuring 587 Ah LFP cells, stores up to 6.25 MWh of energy
The company’s Elementa Flex series ESS is placed inside a single cabinet and stores up to 1.56 MWh of energy
These products can maintain cell-to-cell operational temperature delta within 2.5 °C
The Elementa 3 ESS platform (containerized and single-cabinet-based) from TrinaStorage, the storage arm of Trinasolar, has been named a finalist for The smarter E AWARD 2026 under the ‘Energy Storage’ category.
The containerized product uses 587 Ah lithium iron phosphate (LFP) cells with an energy density of 417 Wh/L, replacing the previous model’s 314 Ah cells. The company claims it results in up to 12.3% higher battery pack energy density, enabling the fitment of 24 packs within a compact container with a maximum capacity of 6.25 MWh. In comparison, its immediate predecessor accommodated 32 units totaling 5.025 MWh within a 6,058 × 2,438 × 2,896 mm (L × W × D) space. It has applications for large-scale utilities.
The cabinet-based peer, Elementa Flex, also uses 587 Ah LFP battery cells with a lower storage capacity of 1.56 MWh. According to the company, this 13-tonne ESS can be transported by a truck and deployed on irregular terrain with space constraints within a 5 m² installation footprint.
Both products feature battery packs with IP67-rated ingress protection. These packs feature insulation layers that are thin at the nanometer level. The company claims that this feature ensures stable performance in high-temperature environments. It also adopts a circulating cooling mechanism that is inspired by biological (living) systems and maintains the cell-to-cell temperature delta within 2.5°C. These cells have a maximum guaranteed 12,000 charging/discharging cycles throughout their lifespan.
