  2. Hi Juliana, the reason for the error is that the grid voltage is set to 254.03 V. Our 3D environment can't handle that. Change it to 254 V (or any other value) and it should work. And of course you are free to contact us on any channel that you prefer (mail, forum, phone), but please consider that it might cause double effort for us if you contact us on two channels simultaneously. Kind regards, Martin
  3. Die genaue Plazierung der Optimierer ist für Dokumentationszwecke erforderlich. Es wäre sehr hilfreich, wenn ich bereits nur eine Markierung im Stringplan setzen könnte, bspw. bei Modulverschaltung.
  4. Wir arbeiten mit SMA Wechselrichtern und setzen Tigos ein. Je nach Wechselrichter sind dafür verschiedene Tigo Typen notwendig. Eine automatische Kompatibilitätsauswahl wäre super! Hier die Kompatibilitätsliste zum Download für Tigos.. https://www.tigoenergy.com/downloads

  6. Hola, trabajé en una simulación y funcionó correctamente, luego quise editar el modelo 3d para visualizarlo y me sale ventana de error que no me. Permite acceder al mldelo 3D Hi! I was working in a simulation I done perfectly, but 5 hours after I opened and It appears with and error in the 3D editor. Thanks
  7. Hi Trond! Just import a 3d model into the 3d design and tick the "use as terrain model" box. The issue then becomes to define mounting surfaces on the terrain. You can either draw mounting surfaces or have them automatically determined (beta). You can also tinker with the auto-settings to perhaps get better results. Hope that helps.
  8. Dear all, this is a bug that was introduced with the latest version, PV*SOL premium 2021 R7. It will be fixed in the upcoming bugfix release, R8. It affects mounted PV systems with various orientations, like east-west systems, on flat roofs. We are very sorry for the inconvenience caused and try to publish the bugfix release as soon as possible. Kind regards, Martin
  9. Hi Jimmy. This is relevant quite often for me. How did you import a terrain model?
  10. This fault is actually not consistent either.... On this file I drew one more polygon and extracted building. Same procedure as the first; but now it worked. File to Valentin_2.pvprj
  11. We experience the same issue in our company. This is a bug that has come quite recently. And it goes for all users File to Valentin.pvprj It looks like the problem occurs when drawing a building from polygon. When adding building from menu, it works as expected.
  12. Hi Hubert, I answered your email already and hope it reached you. Best regards, Frederik
  13. Moin, es wäre noch schön, wenn man in der 3D-Auslegung verschiedene Montagesysteme abspeichern kann (und nicht lediglich eins als Standard). Und, wie mein Vorredner schon anmerkte, wäre ein Zurück-Button in der 3D-Auslegung sehr wünschenswert. Danke!
  14. Hallo, ich habe 2 Strings die seriell auf einem MPP Tracker verschaltet sind. Die Strings werden seperat zum Schaltkasten geführt und dort 'serialisiert'. Irgendwie kann ich das nicht im Kabelplan abbilden?! Ich verkable manuell die Module der einzelnen Strings und versuche den + und --Pol mit dem Schaltkasten zu verbinden. Ich bekomme aber immer den Fehler 'Kabelplan unvollständig'?! Gruß Wolfgam
  15. Hi Marin! Regarding your number 2, I imported a terrain model (I have no need for this myself at the moment, just wanted to try it) and got it to work kind of good in 10 minutes. I'm sure that someone else can make this much better than what I have done in this mock-up. Just wanted to show that it's possible to do and that it may be easier than step #2 if the environment is complex.

    Hi Martin, Thank You for the information. Best regards, Faruk

    Hi Faruk, in order to avoid grid feed in you can set the maximum power clipping to 0%: https://help.valentin-software.com/pvsol/en/pages/system-type-climate-and-grid/#ac-mains Hope that helps, kind regards, Martin
  18. Hi cjSPS199, if you are a manufacturer or licensed distributor and you wish to enter products in our database, you can contact our database team at database@valentin-software.com. Kind regards, Martin

  20. Hi I would like to help with the incorporation of the Victron Energy products. Who can I get in touch with?
  21. Hello, I am trying to simulate the redox flow battery "VoltStorage Smart" with the information provided above and by using the product's data sheet. However, the "level of self sufficiency" of 42.1 % seems too low compared to when I choose other battery systems with similar capacities (e.g. BlueSky or BYD with more than 50 %). Does anybody have an explanation? Maybe my model needs to be adapted? Kind regards Hubert h VOLTSTORAGE.pvprj VoltStorage SMART Technical Datasheet.pdf

    To whom it may concern, How to have situation where the surplus of PV energy does not go to the grid, but the loads are connected to the grid to be fed by the grid when there is no PV output? Best regards, Faruk
  23. Hi Endika, in PV*SOL, you can only import hourly data. Data with one-minute resolution can be synthesized from it afterwards, but you can't import your own, I am afraid. When you import hourly data, and PV*SOL shows a hint that "Input data and clear sky data are not sync", it means that you irradiation data and the calculated position of the sun do not fit together. Most likely it is because of the time zone or other timestamp-related issues. The data must be in local time, without daylight saving time switch, and right-justified. That means the timestamp from e.g. Jan 01, 11:00 refers to data between 10:01 and 11:00. You can easily check if you imported hourly data is in sync with the sun position when you look at the imported irradiation and the elevation of the sun in the diagram editor. Search for a clear sky day, where the irradiation follows a nice bell-shaped curve, and see if the elevation follows approximately the same curve: Here, as an example, these data are not in sync, since the peak of the irradiation comes approx one hour before the peak of the sun's elevation: Here, the data are in sync: Hope that helps, kind regards, Martin
  24. Dear Gerhard, in PV*SOL you can only simulate one whole year. However, you can look at the simulation results in a very high resolution and flexibility afterwards. Use the diagram editor to show the results you like, over time (so you can see every morning as well): Or use the carpet plot, to analyse all mornings of one year at once: Or you can export the simulation results and analyse the data in another tool, e.g. MS Excel or LibreOffice. Hope that helps, kind regards, Martin
  25. Thank you Martin. I finally have imported the file but now I've faced another problem. When I import minutal meteorological data and I try to simulate it minutely, I get the following error: "Error (MinuteSplitter: Input data and clear sky data are not sync.) I've tried importing the meteo data hourly (to simulate minutely) but I get the same message. I attach the meteorological data. Regards, Endika. PVSOL_MeteoGUNE_mm.dat
  26. Is it possible to only perform a simulation for a specific time slot. I would like to look at only the morning hours. I'm still learning.
  27. Dear Aljaz, you can simulate very large PV farms in the 2D mode, no problem. We recommend to make a pre-simulation in 3D with a subset of the modules, e.g. with 1000, depending on your PV farm layout and setup. Then simulate it and write down the yield reduction due to shading: Then configure your complete PV farm in the 2D mode and enter the shading loss from the 3D simulation as shading loss in 2D: Or, follow point 3) from this answer here, but at your own risk: Hope that helps, kind regards, Martin

    Large PV Farms

    Dear all, I have a question, if there is any possibility to simulate large PV Farms bigger then 7500 or 10000 PV panels? Thank you. Aljaz
