Bidirectional Energy Storage Converter 62.5kW CQC 3L PE Wiring
62.5kW AC DC Bidirectional Converter On-grid and Off-grid Type for 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 The 62.5KW small size and lightweight energy storage converter is suitable for both grid-connected and off-grid applications. It is easily for realizing parallel networking of multiple devices to form a small and medium-sized energy storage system. The DC side single stage voltage is 600 to 900V, and can be reach to 98.2% high efficiency. off grid available, strong load adaptability and our bidirectional converter is perfect for all types of load, which includes half wave load and impact load. Three level output, provide low harmonic and good power quality, 3U rack design, small size and easy to maintain.
