The new Sinvert PVS device line for medium sized and large photovoltaic power plants supplements the range of solar inverters offered by the Siemens Industry Automation Division. The three phase transformer less inverters with graded power outputs of 500, 1000, 1500, and 2000 kilowatts achieve an efficiency level up to 98,4%. The top efficiency of the new inverters enables plant operators to realise a higher yield when feeding into the medium voltage grid, for instance in the case of ground mounted PV systems and systems mounted on large roofs.
The new compact Sinvert PVS central inverters are also available in photovoltaic containers, complete with medium voltage components. Using the master/slave technique it is possible not only to increase plant availability, but also to attain a longer plant service life. Furthermore, the efficiency level is higher than that of a standalone system, as the inverters can be switched in and out as required, depending on solar radiation. The efficiency of the solar plant can thus be optimised, particularly in the case of partial load operation: the plant starts up even at low solar radiation, and reaches very high efficiency levels even in the lower performance range. As the inverter sub-unit with the fewest operating hours is always controlled as the master, this enables the operating time to be evenly distributed between the inverters, which will prolong the service life of the plant.
The new Sinvert PVS inverter series can easily be integrated into scada systems through standardised communication interfaces. A graphics display with touch screen enables user-friendly local operation of the inverters and visualisation of the performance data. The new devices comply with the medium voltage guidelines of the German Association of Energy and Water Industries with all requirements including FRT (fault ride through) and active power control.
