Dear Sama Ashraf, There is a procedure you have to follow in SketchUp before you import it into PVsyst. Please send us an email at support@pvsyst.com, and I will send you the tutorial PDF where we explain how to import a 3D scene from SketchUp. Regards, Muhammed Sarikaya

Dear Waiphyo, You can simulate a single string in an inverter with 2 MPPT inputs. You can follow these steps: If you don't check the box "use multi-MPPT feature," it doesn't mean that the simulation will not find the maximum power of your PV array. PVsyst will always find the maximum power. In this situation, PVsyst will only use the power for the calculation and will not take into account the number of entries on your inverter. Regards, Muhammed Sarikaya

Dear Aaron Polo Can you please tell me how you have defined your load profile in the button "user's needs"?

Dear Nahel, Indeed, using millimeters might not be the best choice. Do you know which unit of measurement you are using in your 3D software for drawing your 3D scene project? Regards, Muhammed Sarikaya

Dear Nihal Meena, Try changing the input size to millimeters, as the input size in your 3D software might not be set correctly. If you have any more questions, please don't hesitate to contact me. Regards, Muhammed Sarikaya

Dear Andel In PVsyst, you can simulate an unlimited shed or unlimited trackers only with a bifacial system. Regards, Muhammed Sarikaya

Dear Nikoloz, I'm sorry, but I can't provide an answer without more details about your project. Could you please share a screenshot of your system? Regards, Muhammed Sarikaya

Dear Vera, This is precisely what you need to understand: For this inverter to function, there is a minimum voltage requirement. The 'operating voltage' range is listed as 684-1450 V. It's important to note that temperature affects voltage; the higher the temperature, the lower the voltage. That's why we base our calculations on a module temperature of 60°C. I suggest increasing the number of modules or opting for an inverter with less power. If you need any assistance, please don't hesitate to contact me. Regards, Muhammed Sarikaya

Dear Michalis Angeli, This is not a problem with the trial version. You need to follow my tutorial precisely, as outlined below. To activate the button, click on the surface of your roof. After that, you can proceed with my tutorial. Regards, Muhammed Sarikaya

Dear Michalis Angeli, I understand that creating your project in the 3D scene can be a bit challenging at times. Allow me to introduce another method for constructing your project. Here's how to do it: Right-click on the menu bar where "point of view" is located, and then click on "normal to face." This will reveal the "normal to face" button in the menu: Afterward, your 3D scene should be set to the realistic view for rendering. Following this, you need to click on the surface of your roof. In my example, I clicked on the left roof. To verify if the roof is selected, you'll notice that the color is slightly different from the rest of the building: After clicking on "normal to face" in the "point of view" menu, you'll notice that the view has changed to align with the normal of your selected face: Then, you can create a single PV table by using the "Draw" button located in the "Tools" menu. Following this, draw a rectangle of the size you desire on the surface of your roof. You can later modify the created zone to align with your table. To do this, double-click on the created zone table and make the necessary adjustments. You can also view in basic parameters to check the orientation of your table. If you require further assistance with this topic, please don't hesitate to reach out to me. Regards, Muhammed

Dear Hrira, Please avoid adding too many details to the 3D scene as it makes the simulation more complex and increases the calculation time. For trees, you can easily incorporate a template that we provide into the 3D scene in PVsyst. Here, I'll demonstrate how to do it: In 3D scene, click on : - Create - Elementary shading object - And then select Tree in shape type Then you can modify the dimensions of the tree as you desire. Additionally, after adding it to your 3D scene, you can copy and paste it as many times as needed. If you require further assistance with this topic, please feel free to reach out to me. Regards, Muhammed Sarikaya

Dear Gilberto Borges, With PVsyst, you can simulate a system with self-consumption and grid unavailability. There is a video tutorial that can help you to understand: And a help page also: https://www.pvsyst.com/help/gridstorage_weakgrid.htm I suggest you to watch this tutorial, if there is anything you don't understand, don't hesitate to write me. Best regards, Muhammed Sarikaya

Hello Dear OlliP, I think that the date format is not correct. I noticed in the CSV source file that the month is represented as 'Jan.' and it's likely that PVsyst cannot interpret it correctly. Could you please open your CSV file in Excel and try to change the date format so that the month is represented in numerical form? Regards, Muhammed Sarikaya

Dear Elisdown, You have to contact SMA if your modification will take into account the power sharing between each MPPT. If you want to connect only 3 MPPTs out of 12 MPPTs, PVsyst will not allow it. In reality, you should contact SMA to inquire whether it's possible to configure only 3 MPPTs and if it's allowed. Regards, Muhammed Sarikaya

Dear Mohamed1298, We don't have option for calculating Auxiliaries loss using excel. In detailed loss, you have the definition "Auxiliaries" You have some information in the help : https://www.pvsyst.com/help/auxiliaries_consumption.htm#:~:text=The auxiliaries consumption is the,be sold to the grid. Also, you can defin night auxiliaries losses in the second box. If you have other questions, don't hesitate to ask me. Best regards, Muhammed Sarikaya

Dear Michalis Angeli, It depends of your need, of your project and of the grid manager. Sometimes you have to add power factor and sometimes you don't need. Regards, Muhammed Sarikaya

Dear Michalis Angeli, Thank you for your explanation. In PVsyst, the option self-consumption allows you to simulate the ratio between what you can consume regarding your load profile and what you inject in the grid. Regards, Muhammed Sarikaya

Dear user, I don't understand "With no PV" Can you give me more details about your project? Also, in PVsyst, you most define a load profil if you want to simulate a stand alone project. Regards, Muhammed Sarikaya

Dear Michalis Angeli, I don't know the Net Metering Systems. In the option Self-Consumption, you must use a load profile. You can visualise some example in the folder : \PVsyst7.0_Data\Templates The template is a CSV file and follows a precise pattern: If you have at least hourly values, you can use it in the simulation. Regards, Muhammed Sarikaya

Dear Katinka89, Currently, we can't design your system in PVsyst in detailed. I suggest you to define your system by using one big length, for example take 7,84km in the account. You can also do a calculation to obtain the voltage drop for each portion of the distances you mentioned and then put as a global Loss fraction at STC. I think if your cables have a reasonable section, after simulation, you will not have a big difference. If you have any other question, don't hesitate to write us. Regards, Muhammed Sarikaya

Dear LAUR For the battery database : we use to include the batteries by ourselves. However as our Battery model is rather sophisticated, we need as detailed as possible datasheets of the basic cell used in the products. The specification of the basic cell should include: - The manufacturer and model name, - The chemistry, sizes, weight, etc - The operating limits (min/max voltage, charging/discharging currents, temperatures, etc) - Charge/discharge curves at different rates and different temperatures - The number of cycles and other infos about the lifetime The for each block model, we need : - The model name, - The basic cell model used - The number of basic cells in series and in parallel. - Sizes and weight You may also define assemblies of blocks (racks, etc…) by - The number of blocks in series and in parallel - Sizes and weight If AC input/output devices (charger and inverter) are fully integrated with the products, these cannot be included in PVsyst as such in the present time. PVsyst treats these IN/OUT devices in a generic way, and we need the DC operating conditions of the battery pack itself. Regards, Muhammed Sarikaya

Dear Katinka, I don't understand how you can connect MVPS in series? In your case, I need to know if all your MVPS have the same length to injection point? Regards, Muhammed Sarikaya

Dear abcpvpv, When you import in the 3D scene, in the "import result windows" click the box "apply 180° rotation" Here an example with the highlight: Regards, Muhammed Sarikaya

Dear Nikoloz, You will have only one problem and it's the "overload loss". Depending on your PV module requirements and your PV project, you may be able to accept overload loss, but to know your exact amount, you have to do your simulation first and check at the end of the loss diagram what is the amount of "Inverter Loss over nominal inverter power" Regards, Muhammed Sarikaya

Dear RAF80, We don't have exercises to improve your practice and knowledge. The only thing I can suggest, is to look the different Demo projects we provide within the software. If you click on load, you will find: For Grid connected systems: Demo_Residential Demo_Comercial Demo_Sevila Demo_Utility Also, there are some other demos that you can check out and learn from.
