SMA Solar Technology AG 500 kW at 1000 Vdc 550-1500 V DC-DC DC-DC Converter

The 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 UP 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.

Features
