Product Overview
The Energy Storage Inverter Integrated Machine (ESI) is an integrated core energy storage device that combines a bidirectional inverter (PCS), distribution cabinet, BMS, EMS, lightning protection, fire protection, and temperature control. It is specifically designed for photovoltaic energy storage, wind power energy storage, industrial and commercial energy storage, microgrids, and grid frequency regulation projects. The device achieves efficient AC/DC conversion, supports grid connected, off grid, and islanded operation, and features energy management, peak shaving and valley filling, demand control, and backup power functions. Its integrated design ensures convenient installation, high reliability, and suitability for unattended outdoor operation, making it a core component of energy storage systems.
