Custom 261kWh Industrial Commercial Liquid-Cooled BESS Solar Battery Storage Cabinet Manufacturer
The GSL-BESS-261K is a high-performance lithium iron phosphate (LFP) energy storage system specifically designed for commercial and industrial (C&I) applications. With a nominal capacity of 261.2 kWh, a standard voltage of 832 V, and a wide charging/discharging voltage range of 728–936 V, it employs Grade-A LFP cells and offers a 10‑year warranty. The system operates reliably from -20℃ to 60℃ and complies with IEC/EN safety standards. Its compact integrated design (1300×1300×2340 mm without inverter) facilitates easy installation. It is ideal for microgrids, backup power, off-grid peak shaving, virtual power plants (VPP), and other scenarios, helping industrial parks, office buildings, shopping malls, and charging stations achieve cost efficiency and green energy transition.
