Solar inverters improve the profitability of photovoltaic power plants

The Siemens Industry Automation Division is further expanding its product portfolio in the power plants segment by introducing the central inverters Sinvert PVS600, PVS1200, PVS1800 and PVS2400.
These four new models cover the 600 to 2400 kilowatt (kW) output range and enable operators of photovoltaic (PV) power plants to tune their inverters precisely to the capacity of the modules employed in the plant. In this way, the yield and efficiency of the entire PV plant can be optimized.
The planning process is supported by Sinvert Select, the cost-free Siemens software application, which is capable of calculating suitable combinations of inverters and PV modules. Sinvert PVS inverters have a peak efficiency of well over 98 per cent, making …
