G125K-LE260 Liquid-Cooled Energy Storage Cabinet is an all-in-one C&I battery energy storage system with an integrated 130.5kW PCS, purpose-built for peak-valley arbitrage, demand management, PV self-consumption and backup power. It combines 5 battery packs of 166.4V/314Ah in series (1P260S configuration), delivering a rated voltage of 832V, a rated energy of 261kWh, and a wide voltage range of 728~936V — a complete, plug-and-play DC-to-AC block that installs on site with minimal wiring.
At its core are 314Ah large-format LFP (lithium iron phosphate) cells with 157A standard charge/discharge current at a 0.5C rate, meaning a full 261kWh charge or discharge in about two hours — well matched to daily peak-valley cycling. The system delivers up to 8,000 cycles (EOL 70%, 90% DOD) — roughly 30% longer service life than conventional 6,000-cycle systems — significantly lowering the levelized cost of energy (LCOE) across its lifetime.
Unlike air-cooled cabinets, G125K-LE260 adopts intelligent liquid-cooling thermal management with an ethylene glycol / water (50%:50%) coolant loop. Liquid cooling keeps cell temperature difference within a tight band, supports stable operation from -20℃ to 50℃ at up to 95% RH, and slows capacity fade — a decisive advantage in hot climates such as the Middle East, Africa and Southeast Asia.
The IP54 enclosure integrates the battery cluster, 130.5kW PCS, BMS, aerosol fire-suppression system with temperature and smoke detection, and thermal management in a compact 970×1420×2320mm footprint weighing ≤3,000kg. Factory pre-assembled and tested, it requires only electrical connections on site. With RS485 / CAN communication, it integrates seamlessly with mainstream inverters and EMS platforms for remote monitoring and multi-cabinet paralleling for larger capacities.
