SMA has introduced a new DC coupled storage solution for utility-scale PV projects. The DC coupled storage solution is built for new PV plants, but it can also be used to retrofit existing PV plants for those operators who want to enjoy the benefits of solar-plus-storage. In many utility-scale applications, DC coupling can offer significant operating cost and efficiency advantages over AC coupled systems. The DC coupled storage solution consists of SMA's Sunny Central EV-US line of inverters with a DC coupling ready option and up to six 500 kW SMA DC-DC Converters.
