The state-of-the-art bi-directional DC-DC converter (DPS) is engineered to seamlessly integrate battery energy storage with both new and existing PV power plants on the DC side. Optimized for solar-plus-storage applications, the DPS enhances project efficiency and revenue with advanced features such as automated clipping recapture and low-voltage harvesting. Its DC-coupled architecture streamlines installation and minimizes regulatory complexities, making it a cost-effective solution. Designed for flexibility, the DPS operates across voltage, current, and power control modes, with the ability to switch dynamically between them in real time. Its scalable design allows for seamless parallel integration of up to six units, ensuring adaptability to a wide range of energy storage needs. The DPS is designed for solar-plus-storage applications, electric vehicle charging, and green hydrogen production.
