261kWh LIQUID COOLING C&I ESS

PSB125/261L-E is an all-in-one liquid-cooled commercial and industrial energy storage cabinet rated at 125 kW / 261 kWh. Built with 314 Ah LFP cells, it integrates the battery system, PCS, BMS, EMS, intelligent liquid cooling and fire protection. The compact integrated design reduces footprint and lowers installation and O&M costs. Intelligent zone-based thermal control keeps cell temperature variation within 2 °C, system cycle life exceeds 8,000 cycles and round-trip efficiency reaches up to 90%. Multi-level safety monitoring and fire protection cover the cell, pack, rack and system. Up to 32 units can run in grid-tied parallel and 6 units off-grid, with cloud-based remote monitoring and smart O&M.

Ideal for industrial parks, factories, commercial buildings and distributed energy projects — peak-valley arbitrage, peak shaving, PV self-consumption and energy dispatch.
