These values are typically published by manufacturers on the inverter specification sheets. If you do not have such a sheet then you can use the example data file and scale the input voltage and power to the range of input voltage and power that you need. Inverters tend to be quite efficient (around 95%) except when the input power is below about 5 to 10% of the rated input power at which point their efficiency drops quite a lot.<br>Kind regards,<br> David<br><br><o:p></o:p></p><div><p class=MsoNormal>On 7/18/2013 02:28, Sotiris Papantoniou wrote:<o:p></o:p></p></div><blockquote style='margin-top:5.0pt;margin-bottom:5.0pt'><p class=MsoNormal>Hello Trnsys users,<o:p></o:p></p><p class=MsoNormal> <o:p></o:p></p><p class=MsoNormal>I am trying to model a pv-system with inverter.
