Overview
1.1 Product Features
The three-level medium-voltage high-power energy storage converter independently developed by our company integrates the converter, switchgear, and step-up transformer in an optimized design. It features high single-unit power capacity, flexible application, and easy installation and maintenance. The system can be directly connected to the grid at 10 kV / 35 kV, reducing complex high-voltage system design work, shortening the system design cycle, and lowering overall system costs.
