The three-phase photovoltaic (PV) inverters will help solar plant operator boost
profits during infeed into a medium-voltage system, Siemens says. In addition,
system costs can also be reduced with the option of a voltage window increased
from 900 to 1000 volts.
The new Sinvert inverters are suitable for applications in medium and
large-scale PV power plants.
Depending on the degree of incoming solar radiation, the necessary inverters are
energised or de-energised by a process that increases the efficiency of the PV
plant, especially in partial-load operation. Only the required number of
inverters is operated subject to light intensity.
