Sunpal - 500 kWh Containerized Battery Energy Storage System
Sunpal offers a 20ft Containerized Battery Energy Storage System (ESS) with a capacity of 500 kW output and 1075 kWh storage, catering to commercial and industrial environments. Constructed with a modular design, the system allows capacity adjustments from 500 to 1075 kWh, making it suitable for applications such as peak shaving, grid response, and emergency backup. The system uses advanced LiFePO4 battery modules known for stable discharge and extended cycle life. Technical features include an independent charge/discharge control, real-time monitoring via cloud-based EMS, and IP65 enclosure supporting harsh outdoor usage. The ESS is compatible with smart grid operations, offering remote dispatch and power adjustment, while emphasizing safety through enhanced BMS protection and fire suppression measures. It is designed to integrate with existing renewable systems, providing an efficient energy strategy and reducing operational costs, presenting an ideal solution for businesses to improve energy management and reliability.
