High Voltage Bidirectional AC DC Converter 62.5kW On-Grid And Off-Grid Type
62.5kW AC DC Bidirectional Converter On-grid and Off-grid Type for Energy Storage System
The 62.5KW group series energy storage converter is small in size and light in weight, and is suitable for grid-connected and off-grid applications. It can easily realize the parallel networking of multiple devices to form a small and medium-sized energy storage system, with strong adaptability of power grid and load. Excellent ease of use. A DC branch can be divided into a maximum of two branches for fine battery management
Features
- DC-side single-stage topology: 600 to 900V, maximum efficiency up to 98.2%.
- Can be used off-grid, with strong load adaptability, perfect for all types of load, including half wave load, impact load
- Perfect matching of power battery echelon utilization application scenarios
- Three level output, low harmonic, good power quality.
- 3U rack design, small size, easy to maintain.
