Product Overview
The BESS-T 125-271 is a grid-tied battery cabinet for commercial and industrial load management, peak shaving and solar self-consumption. The integrated PCS delivers 125 kW continuously and up to 137.5 kW for short-term overload, with a maximum efficiency of at least 98.5%.
The battery uses 314 Ah LFP cells in a 1P270S configuration with 864 V nominal voltage and 756-950 V operating range. The cabinet includes a two-stage BMS, a 7-inch touch screen, aerosol fire suppression and dry self-cooling in a 1,500 × 1,520 × 2,400 mm IP55 enclosure.
