The Deye MC-L522-2H3 is a liquid cooled energy storage system delivering 250 kW of rated AC power and 522.496 kWh of nominal battery energy. Built with 314 Ah LiFePO₄ cells, this AC BESS combines battery storage and power conversion in a cabinet designed for commercial facilities and industrial sites.
Liquid cooling actively manages battery temperature during charging and discharging. The system supports an operating temperature range of -30°C to 55°C, with power derating at 40°C and above. An IP54 enclosure and a corrosion protection grade of at least C4 support outdoor deployment, while the cabinet measures 2,000 × 1,400 × 2,440 mm.
Aerosol and water fire suppression provide additional protection. For daily energy management, the MC-L522-2H3 supports peak-to-valley energy shifting, allowing businesses to store electricity during lower-tariff periods and discharge it when tariffs rise.
The system connects to 380/400 V three-phase networks at 50/60 Hz and provides RS485, Modbus TCP and digital I/O interfaces for site integration. Its combination of liquid cooling, outdoor protection and 522 kWh-class capacity makes it a practical option for projects requiring a cabinet-based battery storage solution.
