Hello, I hope you are well. My question is, I wanted to expand an existing solar system, at the moment there are 8 , 480Wp modules with a 6 Kw inverter with only one string used. I now wanted to expand the system with newer 580Wp modules up to the maximum of this inverter. But I don't understand how I do this in the software, inserting 2 different modules for the same inverter. Thank you
