eBox-AL261 Commercial and Industrial Energy Storage System - Product

The Star Charging eBox-AL261 commercial and industrial energy storage system can be widely used in photovoltaic, wind power, grid-connected, and industrial application scenarios. It can be integrated with other energy management products from Star Charging to build a smart energy microgrid. In the smart energy microgrid, the Star Charging eBox-AL261 commercial and industrial energy storage system professionally provides power storage functions, laying the foundation for emergency power supply during unexpected power outages, peak shaving and valley filling, surplus electricity sales, peak-valley arbitrage, and virtual capacity expansion. The highly integrated cabinet design makes the whole system more space-efficient, with higher energy density, and easier transportation, installation, and operation and maintenance.
