developer_mh Posted July 24, 2017 Report Share Posted July 24, 2017 Hi Abraham, thanks a lot for your question. The thing is that the ABB Trio 27.6 kW inverter has to MPP trackers. If you connect 20 Jinko PV modules with 315 Wp on each of them, you will have a DC side power of only 2 * 20 * 315 Wp = 12,6 kWp, whereas the inverter has a rated power of 27.6 kW. The inverter will be underdimensionened by more than 50%, which one try to avoid because of the relatively high inverter losses. But anyways, you can configure the system as you wanted: Just choose the Jinko modules on the PV module page and enter a total number of 40 modules there. Then switch to the inverter page and enter your inverter manually. When you click on the red cross or green ticks left to the configuration table, you'll see the configuration check in order to verify what is wrong with your system: You see that for the MPP voltage and current limits everything is fine, but when you look at the inverter level (marked with a red cross in the tree view), you'll see that the dimensioning factor is only 45 %, while it should be around 100 %: I hope that helps, kind regards, Martin Quote Link to comment Share on other sites More sharing options...
