SAMSUNG SDI unveiled its latest containerized NCA battery-based BESS with up to 6.14 MWh of capacity at RE+ 2025
The company also debuted its LFP battery-based BESS, featuring 2 container-based configurations
It aims to manufacture these products in the US and make them commercially available by the start of 2026
SAMSUNG SDI, a South Korean battery energy storage system (BESS) manufacturer, exhibited its latest products for the US market at RE+ 2025.
BESS for Utility
Aimed at the US’s utility-scale storage projects, the company showcased its latest containerized BESS, SBB 1.7, an abbreviation of SAMSUNG Battery Box 1.7 series, at the show. Housed in a 20 ft container and combined with multiple rack-based NCA (Nickel, Cobalt, Aluminum) battery units, safety devices, and heating, ventilation, and air-conditioning (HVAC) systems, it can absorb or deliver up to 6.14 MWh of energy. According to the company, this capacity represents a gain of up to 16.5% compared to SBB 1.5, its predecessor.
The company also debuted a lithium iron phosphate (LFP) battery-based BESS – SBB 2.0. Unlike the former model, it is designed with two 20 ft containers. With this system, the company has included LFP cell technology in its ESS portfolio for the first time. This cell adopts a prismatic form factor and operates based on electrode technology. Compared to its NCA counterpart, it helps offset LFP’s lower energy density while maximizing inherent advantages such as safety and low cost, stated the company. However, its rated storage capacity is not yet publicly available.
Both products share a common safety feature, called ‘Enhanced Direct Injection (EDI) Technology’, where fire extinguishing agents are sprayed onto the battery modules for fire suppression.
The company plans to manufacture these displayed products in the US and make them commercially available starting in 2026.
