Notes

Siemens SINVERT Select V2.5.1.1_0.3.4603.22450 Page 1 of 4

*Important note: This economic data comprises estimated values based on calculation models. Siemens does not accept liability for any deviations between the specified economic data and the actually achieved values. Deviations may be the result of various factors such as the actual weather situation, technical tolerances of the plant components or soiling of the modules. In all other respects we refer to the technical performance description of the software.

As stipulated in the BDEW Guideline "Generating Plants in the Medium-Voltage Grid", a power factor (cos phi) of 0.95 and a line voltage of 95% UAC need to be taken into consideration with regard to active power when dimensioning the PV array of the inverter. For the line voltage the data sheet values with regard to rated power and max. current have to be taken into account.
