We are currently in the market for solar-powered DC to DC EV chargers with a capacity of at least 400 kW. We're particularly interested in a solution that utilizes solar energy as its primary power source. Our goal is to find a reliable product that not only meets our high-performance standards but also contributes to our sustainability initiatives. In addition to capacity, we'd appreciate details on specifications such as efficiency ratings, charging speed, and any advanced features that may enhance the user experience. It would be great to understand the scalability of your solutions and available options for customization. Looking forward to discussing potential partnerships and the innovative solutions you can offer in this space.
