Realizes bidirectional conversion between DC and AC, enabling efficient charging and discharging. It is the core power conversion device of the energy storage system.

Recovers regenerative energy from elevators and feeds it back to the grid, reducing energy consumption and heat generation.

Automatically switches to backup power when the mains supply fails, drives the elevator to level and open its doors, ensuring passengers can safely exit.

Integrates batteries, power conversion, and energy management to achieve peak shaving and valley filling, backup power, and renewable energy consumption.
