Hi ionut, I'm glad to hear that. Regarding the database update, the manufactures enter their products into our database. Our database team updates the database approximately every two to four weeks. I can't say when specific products will be added because it depends on when the manufacturer enters them. For now, you can add the missing batteries to your personal user database. Here is a description how to add a new battery entry: https://help.valentin-software.com/pvsol/en/databases/components/batteries/#creating-a-new-entry Kind regards Mikio

Hi Tade, thanks for your explanation. I'm unsure which feature you mean. Could you elaborate your statement? Is it for a grid-connected or for a stand alone pv system? The battery systems in the database are composed of individual batteries from the database. Do I understand correctly that you want to connect a single battery to a hybrid inverter via DC intermediate circuit coupling? If so, you can do this by creating a new battery system with that single battery. To do that, please open the battery system database dialog via the top left menu "Databases > Battery Systems (grid-connected). Next click on "New": Than choose "DC intermediate circuit coupling" for the coupling type: In the "Battery" section please click on the database icon: This opens a battery database dialog where you can select the desired battery and confirm with "Select": Again, in the "Battery" you can set the number of batteries and stings to one and save the custom battery system: On the Battery System Page you can now select the custom system via the battery system drop-down menu (please first select the manufacturer under which you have saved the system): Now your battery system only consists of the battery you have selected. You can also view the circuit diagram on the "Plans and parts list" page: Does this answer your question? Kind regards Mikio

Hallo Solar_, vielen Dank für die Anfrage. Zu Ihrer ersten Frage: Ja, das ist der richtige Weg. Dafür gibt es leider keine direkte Möglichkeit in PV*SOL. Tatsächlich würde ich auch die Lösung vorschlagen, die Sie selbst beschrieben haben. Also die stündlichen Erträge aus der CSV Datei mit den Vergütungen zu diesem Zeitpunkt zu verknüpfen. Freundliche Grüße Mikio

Hi ionut, thanks for your interesting questions. I would like to answer them but I'm afraid I would need more concrete examples. Could you provide project files where your questions arise? You can post them in this thread or send it to me via private message. Many results vary strongly depending on the specific scenario with its individual parameters. For example what exactly do you mean by "production"? Do you mean the total energy generated by the pv system ("PV Generator Energy (AC grid)") or the amount of energy that arrives at the inverter? For now I'll try to answer the questions of which I think I have understood what it is about. Please be aware that this answers will not apply in general for any scenario. For systems with AC coupling I would expect that the production ("PV Generator Energy (AC grid)") don't change if you omit the battery but for the "Own Power Consumption" I would think, that it is higher in the scenario with the battery. However, for DC coupled systems it is likely that "PV Generator Energy (AC grid)" is lower with the battery because a part of the energy goes into the battery which leads to losses ("Losses due to charging/discharging" and "Losses in Battery"). Am I right in assuming that the question refers to a DC coupled system? If so, changing the number of batteries allocated to an inverter means changing the amount of energy the system can store on the DC side, which effects the value of "PV Generator Energy (AC grid)". E. g. increasing DC coupled batteries (in DC intermediate coupling circuit) can lead to higher "Losses due to charging/discharging" which causes lower "PV Generator Energy (AC grid)". This relates to your first question and can have various reasons. Simply changing the time of day at which consumption takes place can change the energy balance. If, for example, the consumption of a DC generator coupling system is halved and all other parameters remain unchanged, the value of "PV Generator Energy (AC grid)" slightly drops (if the battery was not already fully utilized beforehand) because if the consumption is lower, there is more energy 'available' for the battery so the battery is used more intensively and therefore there are higher losses due to charging/discharging. However, "PV Generator Energy (AC grid)" shouldn't change if the system is a AC coupled one. There can also be several causes for this. For example, if consumption is very low, more energy is available to charge the battery. On the other hand, if energy is mainly consumed during the day, there is less energy left to charge the battery. I hope that helps a little further. If anything is still unclear, please contact me again. Kind regards Mikio

Hallo SFoerster, vielen Dank für den Report. Ich habe das Projekt bekommen und melde mich so bald wie möglich. Viele Grüße Mikio

Hallo KWR, entschuldigen Sie bitte meine späte Antwort. Bitte melden Sie sich nochmal mit Ihrer Projektdatei per Mail bei unserer Hotline an hotline@valentin-software.com. Dann lässt sich sicher klären, warum die Antwort irgendwo verloren gegangen ist. Vielen Dank für Ihr Verständnis Mikio

Hi Iain, thanks for your post. I'm unsure if I understand your question correctly but maybe it helps if you choose the option "configure module areas together" on the left panel in on the configuration page. Therefor please hold down the control key, select both module areas with the mouse and click on the "configure module areas together" button. Does this help? If not please feel free to ask again. Kind regards Mikio

Hi Martin WALZER, thank you for the request. Unfortunately, the use of sting optimizers is currently not provided for in PV*SOL.in PV*SOL is not possible. Kind regards Mikio

Hello Audrius, hello Felix Galan, again thanks for your report. We could reproduce it and it will be fixed with the PV*SOL Premium 2024 R4 release. Kind regards Mikio

Hallo OWL-Solarkonzept, vielen Dank für die Anfrage. Ich habe sie an unser Datenbank Team weitergeleitet. Dieses wird den Hersteller bitten die Produkte einzutragen bzw. zu ergänzen. Wann sie in der Datenbank drin sein werden hängt davon ab, wie schnell der Hersteller reagiert. Deshalb kann ich dafür keinen festen Zeitpunkt versprechen. Die vier Wechselrichter sind höchstwahrscheinlich schon in unserer Datenbank enthalten, nur nicht mit der Bezeichnung "EF HD-P3-6K0-S1" sondern unter dem Namen "PowerOcean Hybrid Inverter 6kW" usw. Viele Grüße Mikio

Hi ionut, thank you for the request. I forwarded it to our database team. They will ask the manufacturer to add the battery into our database. I can't say when it will be added because it depends on when the manufacturer reacts. Kind regards Mikio

Hi Martin, our database team has contacted the manufacturer and asked them to add the product into our database. As Frederik mentioned, it depends on the manufacturer when the product will be added. In the meantime you can add the inverter to your user-bound database like following: 1. (in the 2D part of PV*SOL) on the top right menu click on "Databases" > "Inverters" 2. in the left "Look Up" filter for companies, search for the manufacturer company name and click on it In case the manufacturer is not listed, you can create a new company entry following this instructions: https://help.valentin-software.com/pvsol/en/databases/components/companies/ 3. in the right panel under "Actions" click on "New" 4. add the missing product according the datasheet and click on save You can now use your created database entry as usual. For further information please have a look at our according online help: https://help.valentin-software.com/pvsol/en/databases/components/inverters/ Kind regards Mikio

Hi ionut, thank you for the request. I forwarded it to our database team. Kind regards Mikio

Hi ionut, thanks for your report. I'm glad it worked. I forwarded your request to our database team. They will contact Huawei to add the battery to our database. In the meantime you can add the missing battery to your user-bound database like following: 1. (in the 2D part of PV*SOL) on the top right menu click on "Databases" > "Batteries" 2. in the left "Look Up" filter for companies, search for Huawei and click on it 3. in the right panel under "Actions" click on "New" 4. add the missing product according the datasheet and click on save You can now use your created database entry as usual. For further information please have a look at our according online help: https://help.valentin-software.com/pvsol/en/databases/components/batteries/ Kind regards Mikio

Hi Sam, yes there is also a replace button for mounted modules but it needs some additional steps. Just as with the roof parallel modules, the module to be replaced must have the same dimensions. To swap the mounted modules please follow these steps: 1. Navigate to the "Module Mounting" tab 2. In the section "Active Assembly System" click on your module and choose "Select/Edit Reference Module" 3. In the "Administration of Assembly System" dialog select your module and click "Edit Assembly System" and then click on "Create a Copy of the Assembly System" 4. In the "Edit Assembly System" dialog, again click on your module and choose "Select/Edit Reference Module" 5. In the "Administration of Reference Module" dialog right click on your module and click "Replace" 6. Select the new module 7. If the two modules do not have the same measures, you will see a message box telling you so Does that help? Otherwise I can add some screenshots. Kind regards Mikio

Hi Johan, thanks for your post. As far as I know it is not possible directly. However, it is possible to export the simulation results as .csv for further processing. Here is our help how to export the results: https://help.valentin-software.com/pvsol/2020/pages/presentation/#simulation-results Kind regards Mikio

Hi Bojan, thanks for your post. I think there must be one module too many at one of the MMP Trackers in the fifth configuration. It is strange that removing modules does not change anything. If the problem persists, you can post the project file here or sent it to me via private message on this forum so that I can have a look at it. Kind regards Mikio

Hi Felix Galan, thanks for your report. Your configuration sounds right to me. A colleague from our hotline told me, that this could happen if the number of MPP Trackers are higher than 20 but I wasn't able to reproduce this behavior. Is your project quit big? Kind regards Mikio

Hallo Sascha, vielen Dank für die Frage. Ja, die durch Eigenverbrauch des PV-Stroms nicht aus dem Netz bezogene Energiemenge fließt in den Cashflow und damit auch in die Berechnung der Amortisationsdauer ein. Warum die Amortisationsdauer etwas länger ist, lässt sich ohne die Projektdatei schwer sagen. Vielleicht sind die Investitionskosten hoch oder der Bezugstarif ist sehr günstig? Falls das nicht weiterhilft, kannst du auch gerne die Projektdatei per Privatnachricht in diesem Forum an mich senden und ich kann versuchen den Grund zu finden. Viele Grüße Mikio

Hallo j.walke, vielen Dank für die Frage. Das Benennen einzelner Module ist nicht möglich. Nur für Modulflächen können eigene Namen vergeben werden. Viele Grüße Mikio

Hi Fred Pacheco, thank you for your question. Unfortunately, the presentation in the "Simulation" table and in the "Energy Flow Graph" on the results page are not ideal for the visualization of net metering, because in the case of net metering the entire PV energy is actually fed into the grid and the PV energy is not consumed directly as the table/graph presents it. It is shown better in the "Financial analysis" section under "Energy supply account", where the savings in kWh correspond to the total electricity produced if the total consumption was higher than the electricity produced. If I understand the situation correctly you don't have to adjust any parameters. The consumption of the electric vehicle should be covered as much as possible by PV energy (first the general consumption is covered and what remains is consumed by the cars battery). However, the real process is indirect, because all the pv energy is first fed into the grid to be credited later. If there are still unclear issues, please feel free to send us your project file by private message in this forum so that we can take a closer look at the configuration and results. You can also find more information in our online help (below under the bullet point "Net Metering"): https://help.valentin-software.com/pvsol/en/pages/financial-analysis/ Kind regards Mikio

Hello ionut, thanks for your post. I'm unsure if I got your question right. Just to clarify, is this the configuration you are looking for? (please see attached circuit diagram) If so, you can achieve this with two battery system groups (this feature is available since version PV*SOL 2024 R1). First ensure that your battery systems coupling type is "DC intermediate circuit coupling". The type of coupling can be checked in the "Type of Coupling" column or via the "Info" button in the database dialog of the battery system under "Type of Coupling". Then you can copy the existing battery system group and set the connection to the inverter to the second inverter in the copied group. Please feel free to reach out if that doesn't answer your question. Kind regards Mikio

Hallo Planer12345, vielen Dank für die Anfrage. Wenn der Screenshot sich in der Zwischenablage befindet sollte er sich direkt über Strg + v einfügen lassen, nachdem Sie in das Texteingabefeld für einen Post geklickt haben. Eine andere Möglichkeit ist den Screenshot durch Klicken auf "choose files..." unter dem Texteingabefeld auszuwählen und hochzuladen. Nach dem Klick darauf sollte sich ein Dialog zum hochladen von Dateien aus Ihrem Browser heraus öffnen. Hier zwei Bilder, wie es bei mir in Firefox aussieht: Viele Grüße Mikio

Hallo FightZ, das verstehe ich, dass das kein zufriedenstellender Zustand ist. Tut mir leid, dass ich nur notdürftig weiterhelfen konnte. Schön, dass Sie dadurch zumindest den Knopf für's Ein- und Ausschalten der Sicherungskopien gefunden haben. Leider kenne ich außer den hier beschriebenen Wegen keine Lösung für die von Ihnen beschriebenen Probleme. Haben Sie schon bei unserer Hotline angerufen? Falls nicht, würde ich das empfehlen. Vielleicht lässt sich im direkten Kontakt eine Lösung finden, die auch die zu kleine Schrift wieder lesbar macht. https://valentin-software.com/support/technischer-support/ Viele Grüße Mikio

Hallo FightZ, vielen Dank für den Report. An sich ist uns aktuell kein neues Darstellungsproblem der 3D Menüleiste bekannt. D. h. die oben von Martin beschrieben Schritte sollten eigentlich weiterhin helfen. Ich habe aber von den Kollegen aus unserer Hotline noch folgenden Tipp bekommen, der eventuell helfen könnte: In den Optionen, die über das Sechskantschlüssel Symbol (das in Ihrem Screenshot zum Glück noch erreichbar aussieht) in der oberen Leiste erreichbar sind, gibt es das Kontrollkästchen "Hauptbuttonleiste vergrößern", durch dessen Aktivierung das Darstellungsproblem sich in vielen Fällen beheben lässt. Sollte das auch keine Besserung bewirken, melden Sie sich gerne nochmal. Viele Grüße Mikio
