Step-down DC-DC converter

step-upinverter

The new SMA DC-DC converter allows designers to increase their PV power plant’s yields by oversizing the DC array without compromising energy losses. This is accomplished with the new DC-coupling option and the generous DC–AC ratios of the Sunny Central EV inverter series. The inverter can intelligently control the flow of power for many different use-cases, including clipped-loss capturing. The stored energy can be fed in at attractive times, for example, in the morning or at night, to achieve a better price-point for the energy. Grid operators are able to benefit from grid services, such as frequency control or time-based feed-in schedules. Up to six DC-DC converters can be connected and operated simultaneously on the Sunny Central inverter. This minimizes battery short-circuits currents for high energy applications and avoids the need for additional and expensive protection measures inside the battery container. Benefits of DC-coupled system layout Retrofittable (storage solution can be integrated anytime) Step-up/step-down converter with battery charge/discharge function Limits high short-circuit currents of the battery Intelligent power flow control of the system in the Sunny Central Coordinated protection concept with Sunny Central High efficiency at different DC voltages as well as partial and full load Enables new business models Optimum integration Plug N´Play Connection No external controller required Full tested and certified solution Fast Installation No additional combiner needed Use of storage independant of PV Retrofittable & Future Proof
