125K Series Liquid-Cooled Commercial & Industrial ESS

The 125K Series is an all-in-one liquid-cooled cabinet-style commercial & industrial energy storage system offered in three capacity variants: 125K209 (209.0 kWh), 125K261 (261.25 kWh), and 125K418 (418.0 kWh), all equipped with unified 125 kVA rated output/UPS power. Custom-built for industrial parks, manufacturing factories, shopping malls, residential blocks and medical hospitals, this integrated ESS delivers core application values including peak shaving, valley filling, on-site emergency backup power, grid load optimization, short-term power regulation, distributed energy trading and transformer capacity upgrade to slash industrial electricity expenditure.

Adopting advanced intelligent liquid cooling technology, the unit works reliably across an ultra-wide temperature span of -40℃~60℃ (derating above 45℃), effectively resolving heat dissipation pain points for high-load industrial energy storage. The embedded inverter supports up to 250 kW maximum PV input via 10 independent MPPT trackers to realize seamless PV-storage hybrid operation, with ultra-high conversion efficiency: 98.7% max AC efficiency and 98.1% max DC efficiency. It features adjustable power factor from 0.8 lagging to 0.8 leading, THDI below 3% and DC injection current less than 0.5In for strict grid-compliant output.

Powered by durable LiFePO4 (LFP) lithium iron phosphate batteries, the battery packs achieve ≥8,500 design cycles under standard test conditions (25±2℃, 0.5C charge/discharge,70% EOL). The intelligent BMS supports up to 4 parallel battery groups and CAN communication, alongside comprehensive multi-layer safety protections covering over-current, over-charge, over-temperature, cell over/under voltage and deep discharge prevention.
