Dear Greg, If you don’t want to import energy from the grid, it’s considered a stand-alone project. I suggest running your simulation as a stand-alone system. In a grid-connected project, the grid supplies energy when the system can’t meet the user’s demand. See my screenshot below: Regards,

Dear RahSolar, Can you please send us your project along with the 3D scene you are using to support@pvsyst.com so we can better understand the issue? I suspect that you are using a 3D file with a larger PV area than what you declared in the system window of the software. Regards,

Dear Carlos, I don’t recommend importing a detailed 3D forest file into PVsyst. The more detailed the 3D scene is, the longer it takes to calculate the shading impact on the PV tables. For the horizon line, you can already import the mountain line in PVsyst using the horizon feature. In the 3D scene, if there is a forest at the edge of your terrain, I suggest drawing a wall to represent the last row of trees. Regards,

Dear JNutter, It’s difficult for us to understand why you are encountering this issue. Could you please send us your project at support@pvsyst.com so we can examine it? Also, please explain the issue in your email. Regards,

Dear Andrés, Can you please send us your .ond file at support@pvsyst.com so we can examine it? Also, could you explain your issue in your email? Regards,

Dear Alex, Is it possible for you to send us your project at support@pvsyst.com so we can test it and compare the results between V7 and V8? In your email, could you also explain the procedure you followed that led to these differences? Regards,

Dear Nikoloz, It seems that the inverter you want to use is a central inverter with only one MPPT. This means all strings connected to it must be identical. So, you don’t need to worry about the MPPT definition. In PVsyst, just select the configuration “PNom sharing within the inverter” (see below). Then, you only need to specify the number of inverters. Regards,

Dear Ishan, First of all, the Unlimited Tracker represents an idealized PV table layout, with all rows having exactly the same length. Most likely, your 3D scene doesn't follow this idealized representation. Could you please send us your project by email at support@pvsyst.com, so I can check it and explain why you're seeing these differences? Regards,

Dear Oli, Unbalanced inverters are not designed for power sharing. Regards,

Dear Arisk, Unfortenately, this is not possible. Regards,

Dear Ville, Unfortunately, with a central inverter in PVsyst, it's not possible to perform what you want to do. You can try to modify the OND file by allowing multiple MPPTs, but this will not reflect reality. Regards,

Dear Edwin, Thank you very much for your feedback and for taking the time to report this bug. Could you tell me how this situation occurred in your case, where the Medium Voltage panel remains visible even though you selected HV transformers? I need to reproduce this bug on my side in order to fix it. Regards,

Dear, I can’t help you with AutoCAD or how to convert the topography to a CSV file. Maybe just make sure to check the X, Y, Z coordinates in the CSV. With version 8, we can import topography from the internet — it might also be useful for you. Here’s how to do it: In Near Shading, click File > Import > Download a satellite ground image and/or ground data Then, don’t forget to check “Also import topography data” Regards,

Dear Cleyson, I created the PAN file based on the datasheet and didn’t get any error messages, see below: Click on the "Model parameters" tab and select the default value for series resistance, as shown below: Try using exactly the same settings and let me know if anything changes for you. Regards,

Dear, We update the database using the requests of the manufacturers, and publish it with each new issue of PVsyst. We can't of course follow all the new products of all manufacturers in the world. Therefore, please ask your provider/manufacturer to take contact with us for updating the database. Nevertheless you can easily create your own components by yourself. The easiest way is to choose a similar existing device in the database, modify its parameters according to the manufacturer's datasheets, and save it under a new name, therefore creating a new file in your database. You have a tutorial for that on youtube: Regards,
