Hi S.A.Basit, the usage of the cable plan in 3D is documented here: http://3d-help.valentin-software.com/pvsol/en/#t=html%2Fen%2F3d%2FEinfuehrung_in_den_Kabelplan.htm If you need further information, please don't hesitate to ask. Kind regards, Martin

Hi Ricardo, this is an interesting case! Could you please provide the project files (the big one and the three small ones), so that I can have a look what is happening there? You can either send them here directly or by private message. Thanks a lot, Martin

yes, R7. But right now we don't have a release schedule for that, sorry. Kind regards, Martin

Hi Ries, there was indeed an error in summing up the areas of the module surfaces that are connected to one inverter. Thank you for calling our attention to that. It happens in cases when not all modules from one module area are connected to one inverter. Actually a case that occurs not so seldomly, and it was correct in versions before 2019 R1, but we refactored parts of our code base where this bug came in. Again, thank you for finding this. We will release a bug fix in the next bugfix release - but not in the upcoming R6, since this is already on the way. Kind regards, Martin

Hi Tim, thanks for the question. Right now there is no option for wind turbines, but we will add it to our list of feature requests. Thanks and kind regards, Martin

Hello Hayder Ali, thank you for your question. I am afraid that this is not possible at the moment. But we will put it on the list of feature requests. Kind regards, Martin

Hi Magnus, yes, I will forward this request to our database team so that they can contact Ja Solar in order to have their newest products inserted into our database. If you want, you can also contact the manufacturer directly (as they are responsible to update the database entries) or send a notification to our database team at database@valentin-software.com Kind regards, Martin

Hi Ries, could you provide a project file, please? This would make it easier for us to see what is going on there. You can either post it here directly or send it to me via private message. Thanks a lot in advance, Martin

Hi Jack, if the desired inverter is not in our database (which is filled by the manufacturers), you have two options: Enter the inverter yourself Contact the manufacturer to enter their inverter Ideally, you could do both, so that you can start planning your PV system with the inverter right away and you have the manufacturer notified of the missing entry. The easiest way to enter the SE50K manually is to create a copy of the SE33.3K and change the values according to the datasheet (https://www.solaredge.com/sites/default/files/se_commercial_three_phase_inverters.pdf) I will inform our database team so that they as well can contact SolarEdge to have the new products entered. Thanks and kind regards, Martin

Hi Tim, if you combine SolarEdge (SE) power optimizers with non-SE inverters, one difference will be the DC voltage range. SE inverters usually have a fixed DC voltage, other inverters have a rather wide range of several hundreds of volts where they can track the IV curves and find the maximum power point (MPP). The output will be slightly different, yes. The best way to find out these differences is just to simulate different systems and compare the results Kind regards, Martin

Hi Kristian, I am afraid that this is not possible at the moment. Right now the starting SOC of the batteries in stand alone (offgrid) systems is determined by the average SOC that is roughly to be expected during operation. For that we take the SOC control parameters of the diesel generator: Considering the time and the SOC thresholds we determine an "average" SOC that is used as a starting point. This behaviour was desired by the SMA engineers to avoid untypical system behaviour in the beginning of the simulation (the offgrid simulation part of PV*SOL was design for SMA in the first place, some years ago). But we will put this feature request on our list, thank you. Kind regards, Martin

Hi Low Carbon Exchange, thank you for your feedback! We will look into that for the next release. Kind regards, Martin

Thanks for the project. For me, this looks fine. The nominal output current of the Enphase inverter is max. 1.5 A (350 W / 230 V), usually it will be far less since you only have the 320 Wp from the module when the irradiance is at 1000 W/m². But even if you have 1.5 A output from the inverter, your ohmic power loss is only about 0.4 W (P = I² x R). The resistance of your cable is 0.18 Ω ( ρ*l/A, 0.018 Ω·mm²/m * 25m / 2.5mm²). So the relative losses on the AC side in your worst case are 0.4 W / 350 W = 0.12 %. In the DC side, you have 9.6 A MPP current (under STC, like above) and a cable resistance of 0.018 Ω·mm²/m * 2m / 4mm² = 0.009 Ω, so a power loss of 0.83 W (or relative 0.83/320 = 0.36%). So, when comparing ohmic losses, be sure to always have an eye on the currents. Cheers, Martin

Hi Sander, could you provide us with a project file so that we can investigate your test case better? You can either post it here or send it over by private message. Thanks a lot, Martin

Hi Sander, thank you for the post, it is interesting to see that Huawei now also provides power optimizers. From the datasheet and their website it is not clear, however, in which optimizer mode they really operate. See an explanation on the operation modes here: https://help.valentin-software.com/pvsol/2019/calculation/power-optimizer/ To include them into our database, we have to make sure we get the optimizing mode right. I will inform our database team so that they can contact Huawei to ask for more information. In the meanhwile you could either ask them directly or you could just enter the device as a SolarEdge device (full mode), if you want to accept the risk of choosing the wrong optimizing method. Kind regards, Martin

Hallo Sepp, ich habe das gerade hier nachvollzogen und kann es leider nicht nachstellen. Das heißt, bei mir ist das Logo auch auf anderen Rechnern als meinem zu sehen. Welche Version von PV*SOL benutzt du denn? Ist das Logo evtl schreibgeschützt oder in einem geschützten Bereich (Netzlaufwerk oä?). Evtl. könnte Abhilfe schaffen, das Logo zuerst auf den Rechner zu kopieren, auf dem auch PV*SOL installiert ist und es dann in den Benutzer-Optionen neu auszuwählen. Über eine kurze Rückmeldung, ob das geholfen hat, würden wir uns sehr freuen. Viele Grüße, Martin

Hi João, No, sorry. But you could simulate the 3D environment without tracking, save the shading losses from the results and enter them as a shading percentage of your 2D simulation with tracking system. This will only cover the shading by far objects (homogeneous shading), however. A detailed shading analysis with mutual shading of the trackers for example, is not possible. But if the tracking systems have sufficient distance from each other, this won't be problematic. Hope that helps, kind regards, Martin

Hi Tim, thank you for the interesting question. I guess it is neither a real issue nor a limitation of our software If you select SolarEdge power optimizers with inverters of different manufacturers you will get a "warning" from PV*SOL, stating that the optimizers may only be used with inverters from SolarEdge. This is because SolarEdge says so (not sure why), but since it is only a warning in PV*SOL, you can simulate the system anyway. We heard from other planners that they combine SE power optimizers with other inverters as well. But perhaps check again with SolarEdge what their opinion is on that topic. Kind regards, Martin

Hi matko89, please only write one post per issue, thank you. This will keep things easier to follow up for you and for us as well. Did you get positive feedback on the deactivation form? If yes and the problem persists, please contact our technical hotline at hotline@valentin-software.com. Kind regards, Martin

Hi matko89, did you get positive feedback on the deactivation form? If yes and the problem persists, please contact our technical hotline at hotline@valentin-software.com. Kind regards, Martin

Hi João, could you provide us with the project files so that we can analyse the comparison? Without seeing the PV system and the meteo data it is impossible to tell where the difference in PR and yield comes from. Thanks a lot in advance and kind regards, Martin

Buenas dias Felipe, let me give an English translation of your Spanish question first: So, the answer would be to try the following work-around: That is: Install the newest version of PV*SOL premium (right now it is 2019 R5) Run it once and close it, so that you find the file PVSOL.ini in this folder: C:\Users\USERNAME\Documents\Valentin EnergieSoftware\PVSOL premium 2019\PVSOL.ini Open it in a text editor and search for the element <MainPagerWider>0</MainPagerWider> Change it to <MainPagerWider>-1</MainPagerWider> and save the file Start PV*SOL premium  In Espanol: (Traducción realizada con el traductor www.DeepL.com/Translator) Instalar la última versión de PV*SOL premium (ahora mismo es 2019 R5) Ejecútalo una vez y ciérralo, para que encuentres el archivo PVSOL.ini en esta carpeta: C:\Users\USERNAME\Documents\Valentin EnergieSoftware\PVSOL premium 2019\PVSOL.ini Ábrelo en un editor de texto y busca el elemento <MainPagerWider>0</MainPagerWider>. Cámbielo a <MainPagerWider>-1</MainPagerWider> y guarde el archivo Iniciar PV*SOL premium Hope that helps to finish your project! Martin

Hi flak and others, there are no updates, I am sorry. We will keep you posted. Kind regards, Martin

Hi Ricardo, you can extrude the 3D object from a non-rectangular polygon and apply the inclination afterwards. Just right click on the object, select "Edit", then choose the edge that should act as rotation/inclination axis and enter an inclination value: Hope that helps, kind regards, Martin

Hello cedric, you can install PV*SOL on the new computer, then revoke the serial number on the first computer and enter it in the PV*SOL installation of the new computer. Keep in mind however that you can't swap your license infinitely. You can do this twice a year. After that you will need to use our form "Software Reacitivation Request" here: https://www.valentin-software.com/sites/default/files/downloads/sonstiges/en/request-reactivation.pdf Kind regards, Martin
