Strang- und Hybridwechselrichter zusammenschalten + Batterie
developer_bh replied to MJ_Tom's topic in PV*SOL
Hallo Tom, ja dies dürfte machbar sein. Wenden Sie sich am besten an die Hotline zur weiteren Klärung. Beste Grüße, Ben -
Hello Ryan, the difference is caused by the minimum SOC and maximum SOC values of the battery system (90%, 20% = 30% "loss" overall, means 70% usable energy). If you calculate the overall energy (460.8 * 53) and multiply it by the value (0.7) you will get the amount displayed in the bottom left corner. Best regards, Ben

Hello @Nanta Ragavander, peak shaving is already covered via time controlled charging. Specific limits can be set for the charging period. What is not currently implemented is a limit on the overall power that can be drawn from the grid. Such a function would be technically more challenging to implement, as it could potentially lead to shortages that would have to be taken into account. Best regards, Ben

Hey CarlSEL, there are two ways to read your question: Do you mean what is the accuracy of the hourly GHI values from Meteonorm in comparison to the minute values? Or do you mean what is the accurarcy of Meteonorm 8.2 overall? The second question is hard to answer, because the evaluation is not simple. Meteonorm offers TMY's, which means they don't represent a specific year (which you could evaluate if you have the exact weather data + output data of that location), but a represantative year of at least 10 years. On top of that, Meteonorm uses a special synthesis method of satellite data which is part of their business secret. But we evaluated the meteonorm 8.2 files internally in regards to plausibility, similiar to NREL studies [1]. MeteoNorm 3x3(COV).bmp You can see that the meteonorm data for germany has a really low COV, which is a very good result and means that it's very plausible.

Dear Miro, Thank you very much for your enquiry and the good pictures. I will forward them to the right address. I am pretty sure that we will have more skylight objects in the new 3D environment and that you can set a height above 0.5m. We cannot give a date yet, but in case of your requirements I'm quite optimistic that it will be part of the new 3D. Best regards, Ben

PV-Sol-Datei lässt sich nach dem verschicken nicht mehr öffnen
developer_bh replied to Markus H's topic in PV*SOL
Hallo Markus, das ist wirklich ungewöhnlich, denn das Dateiformat (pvprj) sollte normalerweise von PVSOL erkannt werden. Es ist auch normal, wie Tripe-S schon sagt, dass man die Datei auch als Archiv öffnen kann und dann die einzelkomponenten sieht, wie du eingangs gezeigt hast. Hat die Datei vielleicht noch eine andere Endung? Wenn du rechtsklick darauf ausführst, dann auf "Eigenschaften" klickst und dann auf "Details", was wird dort als Name und Typ angegeben? Wenn du magst kannst du mir die Datei gerne einmal per PN senden. Viele Grüße, Ben -
Hello, I translated your message with DeepL. I hope I got it right. Please consider asking in english next time. Could specify which shortcuts you would expect for which action and name some references where this is applied? You can find tutorials in english on our youtube channel https://www.youtube.com/@valentinsoftware/videos We also offer free webinars (in german and english) on our website. https://valentin-software.com/en/training/webinars/ We are trying to improve our performance. If you encounter a bug sending a bugreport helps us identify the weak spots and bugs. We are currently working on a completely new 3D environment which will also perform better. ------------------ Hej, du, Jeg har oversat din besked med DeepL. Jeg håber, jeg gjorde det rigtigt. Overvej venligst at spørge på engelsk næste gang. Kan du specificere, hvilke genveje du forventer til hvilken handling, og nævne nogle referencer, hvor dette anvendes? Du kan finde vejledninger på engelsk på vores youtube-kanal https://www.youtube.com/@valentinsoftware/videos Vi tilbyder også gratis webinarer (på tysk og engelsk) på vores hjemmeside. https://valentin-software.com/en/training/webinars/ Vi forsøger at forbedre vores performance. Hvis du støder på en fejl, kan du sende en fejlrapport, som hjælper os med at identificere de svage punkter og fejlene. Vi arbejder i øjeblikket på et helt nyt 3D-miljø, som også vil fungere bedre.

Please start a version for Mac. This would be such an improvement
developer_bh replied to Njigba's topic in PV*SOL
Hey Njigba, Unfortunately I cannot give you any specific feedback on this wish other than that this topic is not on our schedule at the moment. This does neither mean that it will never be realized, nor the opposite. Some users figured out how to use PVSOL via wine on mac/linux. While there is no official support, this might be interesting for you. I cannot guarantee that this works of course. You could also try emulating windows on your mac with parallels f.e.. Best regards, Ben -
Probleme mit Darstellung von Sperrflächen im Übersichtsplan
developer_bh replied to Steven's topic in PV*SOL
Hallo Steven, in der neuen 3D Umgebung an der wir momentan mit Hochdruck arbeiten wird es die Möglichkeit geben Sperrflächen für jeden Plan anzuzeigen oder optional auszublenden. Viele Grüße, Ben -

Hello! The (altitude) data is retrieved from external sources. In the program there is no official way to edit the altitude at the moment. However, I will provide you with a script that allows you to change the altitude of a given weatherfile (.wbv). Please follow these steps Download the ps1 script (powershell script, windows) from the attachment of this answer Copy the WBV (f.e. "Berlin.wbv") you want to change in the folder of the script (f.e. Desktop/WbvBackups) twice ("Berlin.wbv" - file to change the altitude, "Berlin_backup.wbv" file as a backup of the old state) Delete the WBV in MeteoSyn via Listview context menu (Headsup - this will delete the file, so make sure you have the backup from step 2) Open a shell in the folder (f.e. Desktop/WbvBackups). You can do this in the explorer by navigating to the destination folder and typing "cmd" in the path, then press Enter. Activate the script by the following command : powershell -File "PATH_TO_THE_SCRIPT" -filePath "PATH_TO_WBV" -newValue ALT_VALUE powershell says it will open the powershell (you usually need administrator rights for that) the string after -File directs to the script path the string after -filePath directs to the WBV path the number after -newValue is the new altitude Import the changed file in meteoSyn Check if the new altitude is correct. Do a simulation with the new file to make sure it works as intended. If everything succeeds you may delete the backup from step 2. I hope this is a good work around for now!? I will forward the feature request to the team to make this process easier from within the program, but cannot give you a specific date for the implementation. Best, Ben change_wbv_altitude_value.ps1

Usinge measurement data of diffuse and direct irradiation
developer_bh replied to demanding_client's topic in PV*SOL
Hello, you can change the used model to get a better accuracy depending on the situation in the simulation options. You can also adjust other parameters in that dialog. You will find detailed explanations here : https://help.valentin-software.com/pvsol/2019/calculation/irradiation/diffuse-irradiation/ https://help.valentin-software.com/pvsol/2019/calculation/irradiation/irradiation-onto-inclined-plane/ Here is a quick overview of some models. Erbs model: This model uses empirical correlations to derive the diffuse radiation from the total radiation. It is often used for hourly or daily data and is well suited for mid and low latitudes. Liu-Jordan model: A simple and widely used model based on the assumption that the diffuse radiation is evenly distributed from the sky to the solar modules. It takes into account the solar constant and the zenith angle of the sun to separate the components. Hay-Davies model: The Hay-Davies model takes into account both the direct radiation and the diffuse radiation components caused by scattering in the atmosphere. This model differentiates the diffuse radiation into isotropic and anisotropic components, with the latter being preferentially scattered in the direction of the sun. Perez model: The Perez model is an advanced model that divides diffuse radiation into several components, including isotropic sky diffusion, anisotropic scattering by clouds and reflected radiation. It is particularly suitable for accurate simulations under different atmospheric conditions and is often used in complex PV simulation software. The Hofmann model is usually a good choice. You find more details about it f.e. here https://www.mdpi.com/1996-1073/10/2/248 At the moment you can only use models based on GHI data. Best regards, Ben -
Hello Luis, We are working on the new 3D environment, which includes functions such as Undo-Redo. Unfortunately, I can't give you a specific release date yet. Best regards, Ben

Hallo Dirk, wir arbeiten hart um unsere Software zu verbessern. Kürzlich gab es eine große Verbesserung mit der Einführung der Google-Solar API. Parallel dazu entwickeln wir, wie Sie wissen, eine neue 3D Umgebung. Zusätzlich gibt es weitere Verbesserungen, so können Sie beispielsweise bald eine neue Klimadatenquelle erwarten. Als Lizenzeigentümer haben Sie vollen Zugang zu allen Verbesserungen. Mir ist aus der Historie bewusst, dass Sie gewisse Punkte schon seit längerer Zeit erwarten. Wir nehmen das ernst und sind bestrebt dies umzusetzen. Ich habe Ihre Wünsche nochmals an das Team weitergeleitet. Aufgrund der Vielzahl an Kundenwünschen und der großen Anzahl bereits gebundener Ressourcen kann ich allerdings keine festen Zusagen machen. Viele Grüße, Ben
