The Deye MC-L522-2H2 is a commercial and industrial energy storage system combining 250 kW of rated AC power with 522.496 kWh of nominal battery energy. Built with 314 Ah LiFePO₄ cells and liquid cooling, this AC BESS supports energy management for commercial facilities and industrial sites.
Designed for peak-to-valley energy shifting, the system allows businesses to store electricity during lower-tariff periods and discharge it when tariffs rise. Liquid cooling manages battery temperature, while aerosol and water fire suppression provide additional protection. An IP54 enclosure and a corrosion protection grade of at least C4 support outdoor installation.
The MC-L522-2H2 supports 380/400 V three-phase connections at 50/60 Hz. RS485, Modbus TCP and digital I/O interfaces enable integration with site energy management systems. With compatible Deye equipment, it can support projects requiring solar integration, generator coordination and backup power, providing flexible configuration options for commercial and industrial energy storage applications.
