Dear David,
Thank you for your reply. Using the plug-in and characteristics found on the web we managed to add the required parameters in type 194. However, information for the inverter are required as well. I suppose that the converter’s characteristics are loaded from the dat external file. Where can we find similar data for other converters?
Thank you a lot
Sotiris

Sotiris,
Please keep in mind that there are two different parameters that ask for information about series configuration. The first (parameter 10) is the number of cells that are wired in series within a module. The second (parameter 11) is the number of modules that are wired in series in the array. The first, will probably cause little change in results and really should not be changed unless you are also changing the other parameters that describe the module performance (short circuit current, open circuit voltage, etc.) The second of the two parameters (parameter 11) should affect the array voltage but not necessarily the array power (so long as the total number of modules stays the same). Make sure also that you are looking at the array maximum power point power.
In order to change the parameters of Type194 you can use the plugin (icon in the lower left hand corner of the parameters tab). You might also consider using Type94, which is a simpler model that requires parameters that can typically be read directly from a manufacturer's specification sheet.
Kind regards,
David

Dear TRNSYS users,
I am a new user of TRNSYS software and I encounter some difficulties with the type 194 (PV- inverter). The problem was occurred when I try to change the N-series and I didn’t watch any difference in the results. First of all, I would like to know whether the example of photovoltaic in Trnsys17 runs without a problem if I don’t change or add any of parameters or not. How can I put my parameters in this type? Is there any user who can help me or have another example?
Thanks and Best Regards
Sotiris
