mmakatri Posted December 7, 2019 Report Share Posted December 7, 2019 Hi , In the attached picture , How I can use PV*SOL to planning my project ? Thank you in advance Quote Link to comment Share on other sites More sharing options...
developer_mh Posted December 9, 2019 Report Share Posted December 9, 2019 Hello mmakatri, on the page "System, Climate and Grid", choose the System Type "Grid-Connected PV System with Electrical Appliances and Battery Systems". Then you can select battery systems on the Battery Systems page. There are three types of systems, as described here: https://help.valentin-software.com/pvsol/2019/calculation/battery-systems/#type-of-coupling Yours would be a "DC intermediate" or "DC-link" coupling. Hope that helps, kind regards, Martin Quote Link to comment Share on other sites More sharing options...
mmakatri Posted December 12, 2019 Author Report Share Posted December 12, 2019 Thank you developer_mh but what about the converter from DC to AC shown in the picture bellow ? Quote Link to comment Share on other sites More sharing options...
developer_mh Posted December 19, 2019 Report Share Posted December 19, 2019 Dear mmakatri, I am not sure if I understand your question correctly. What do you mean by "what about the converter"? Kind regards, Martin Quote Link to comment Share on other sites More sharing options...
mmakatri Posted December 24, 2019 Author Report Share Posted December 24, 2019 Dear developer_mh Thank for your answer, In my system I do not have DC/AC inverter connected to the grid because we do not have a grid , So how I can use this system type, The system will take in consideration the DC/AC inverter (Wiring , Cost, drop etc) Thank you in advance Quote Link to comment Share on other sites More sharing options...
mmakatri Posted December 24, 2019 Author Report Share Posted December 24, 2019 Dear developer_mh, Our system is more like this image but I did not find this type in the PVSOL Quote Link to comment Share on other sites More sharing options...
developer_mh Posted January 6, 2020 Report Share Posted January 6, 2020 Dear mmakatri, if you don't have a grid, i.e. a "stand-alone" (or "offgrid") system, the only two system types that you can use are the last two from the list: For stand-alone systems, we don't have DC/DC coupled battery systems at the moment, I am afraid. But you can do the following to approximate your system: Set the grid voltage to your DC bus voltage (12 V or 24 V, or whatever you use in your system) Also set the mains voltage of the PV and the battery inverter to the same voltage modify the DC/AC efficiency of the PV inverter and the AC/DC efficiency of the battery inverter so that the "PV to battery" , the "battery to load" and the PV to load" energy paths are met as precisely as possible On the cabling page, just set the cable lengths of the AC side as your DC bus cables The results will be very close to a real DC coupled offgrid battery-PV system. Hope that helps, kind regards, Martin Quote Link to comment Share on other sites More sharing options...
