Sunny CenTral for direct medium-voltage feed-in 400MV / 500MV / 630MV The compact station for safe grid management
Thestationhasgotit:EquippedwithanSMAcentralinverterofthenewHEfamilyandamedium-voltagetransformer,theSunnyCentralMVfeedsdirectlyintothemedium-voltagegrid.Theadvantage:Byremovingtheneedforthelow-voltagetrans-former,theplantoperatorrealizesgreateryieldsandatthesametimelowerinvertercosts.TheSunnyCentralMVisdeliveredasa“turnkey”concretesubstationforoutsideinstallation.Ontopofthat,theSunnyCentralMVactivelyparticipatesingridmanagement,andtherebyfulfilsallrequirementsoftheMedium-VoltageDirectivevalidasofJuly2010.
