Lazare Fesnien Posted October 2, 2023 Share Posted October 2, 2023 The error message in red is normal. You have defined a PV power on your main input well below its nominal power (55 KWac). You need to increase the number of strings on this main input Link to comment Share on other sites More sharing options...
