ZhAta Posted May 7, 2019 Report Share Posted May 7, 2019 Hi, I hope you can help me. I am trying to configure an east-west system, 778 JA Solar 270 W panels in total, 389 per side with Fronius ECO 27 inverters and I don't seem to be able to find the right string configuration. If I try to use the maximum number of strings, the MPP voltage too low and the current to high: Or if I try to reduce the number of strings, the open circuit voltage becomes too high: I have tried using different panels and number of panels per string or having a south-facing system, but nothing seems to work with this inverter. I seem to be in an impasse and any recommendation will be much appreciated! I am also attaching my design file for reference. Thanks for your help!
