Hallo Tim, vielen Dank für die Zusendung der Projektdatei. Es handelt sich um einen Bug. Unsere Entwicklungsabteilung arbeitet an einer Lösung. Kurzfristig hast du leider nur die Möglichkeit, den Schaltplan zu exportieren und die Kabelanzahl in einem Bildbearbeitungsprogramm anzupassen.

Hello, Thank you for your inquiry. You can configure multiple module areas on different roof areas together. First, define which modules should be configured together. Select the desired modules from the first module area, right-click on the selected modules, and choose "Add to 'Define Module Areas' Dialog." Then use the dropdown menu in the top menu bar to switch to the second building. Now select the desired modules of the second module area, right-click on the selected modules, and choose "Add to 'Define Module Areas' dialog." Then click the "Define Module Areas for Configuration" button: You can rename the module areas if necessary (right-click → Rename). Then click "Configure": In the inverter configuration window, select both module areas and click "Configure module areas together": Select both checkboxes for "Polystring configuration" and "Connect strings with the same number in series," and assign both module areas to string 1: String 1 now runs across two separate roof areas: You have already implemented the parallel configuration of two strings, each with 19 modules, on the same roof area:

Hello everyone, I am redesigning the string layout of an existing PV system after removing some modules. The physical module layout should remain as close as possible to the existing installation. In the new design, every string must have exactly 19 modules in series. I have two separate questions: 1. Some 19-module strings have to run across several separate roofs. The roofs have the same tilt and orientation. Is it possible in PV*SOL to define one electrical string whose modules are placed on different separate roofs? 2. Independently from that, some strings have to be connected in parallel, for example two separate strings with 19 modules each as one parallel string group. How should this be modelled correctly in PV*SOL? The strings crossing several roofs are not necessarily the same strings that are connected in parallel. My main question is: Can PV*SOL handle both cases in one project, while keeping the real physical module placement as much as possible? If this is not possible directly, what would be the recommended workaround for a realistic yield comparison? Thank you very much for your help.  

Hello, Thank you for your inquiry. On the "System Type, Climate and Grid" page, you can select the "Stand-alone PV System" (with and without a backup generator) system type. Planning stand-alone systems in PV*SOL is based on the SMA Off-Grid Configurator program, which we originally developed for SMA. This program contains the design rules that SMA has specified for us. These rules cannot be changed or deactivated. For example, only systems with AC-coupled battery systems can be planned; DC systems are unfortunately not possible. We understand that these rules may not necessarily apply to other manufacturers and may entail further limitations. For greater flexibility in component selection and improved transparency during the planning process, we recommend that you initially plan your stand-alone system as if it were a grid-connected system: On the "System Type, Climate and Grid" page, select a grid-connected system. Set the feed-in limit to zero; then no energy will be fed into the grid: The value under "Total consumption covered by grid" indicates the energy that cannot be covered by the PV system. This energy must be provided by the backup generator or (if you are not planning on a backup generator) "approach zero".

Hello, Thank you for your message. Registration on the Rexplorer website is not required. You can generate an API key within the PV*SOL premium 3D environment. If you do not yet have an API key for Rexplorer, or if you have not yet entered it in PV*SOL premium, only the button for managing the API key will appear. Clicking the button will take you to the window where you can manage the API key. In this dialog, you can manage your Rexplorer API key. If you don’t have a Rexplorer API key yet, simply leave the API key field blank. An account will then be automatically created on Rexplorer using the email address displayed above, and an API key will be generated.
