Turnkey Delivery • Without low-voltage transformer: greater plant efficiency due to direct connection to the mediumvoltage grid • Complete with medium-voltage transformer and concrete substation for outdoor installation • Medium-voltage switchgear systems for a flexible structure of large solar parks • AC transfer station with measurement • Medium-voltage transformers for other grid voltages (deviating from 20 kV) Sunny Central for direct medium-voltage feed-in 400MV / 500MV / 630MV The compact station for safe grid management The station has got it: Equipped with an SMA central inverter of the new HE family and a medium-voltage transformer, the Sunny Central MV feeds directly into the medium-voltage grid. The advantage: By removing the need for the low-voltage transformer, the plant operator realizes greater yields and at the same time lower inverter costs. The Sunny Central MV is delivered as a “turnkey” concrete substation for outside installation. On top of that, the Sunny Central MV actively participates in grid management, and thereby fulfils all requirements of the Medium-Voltage Directive valid as of July 2010.

Remote controlled power reduction in case of grid overload In order to avoid short-term grid overload, the grid operator presets a nominal active power value which the inverter will implement within 60 seconds. The nominal value is transmitted to the inverters via a ripple control receiver in combination with the SMA Power Reducer Box. Typical limit values are 100, 60, 30 or 0 per cent of the nominal power. Frequency-dependent control of active power As of a grid frequency of 50.2 Hz, the inverter automatically reduces the fed-in of active power according to a definable characteristic curve which...
