FICHTNERINDIA Posted November 1, 2017 Share Posted November 1, 2017 How to design string inverter in PVsyst? String inverter shall have minimum efficiency of 97%.Design Ambient temp. is 50 deg C.Suppose 25 modules are in series in a string and 10 strings are in parallel. Then, 1 inverter is required. However, I am confused how to design string inverter for each of the 10 strings. Please help! Link to comment Share on other sites More sharing options...
linkeshd Posted January 18, 2018 Share Posted January 18, 2018 If I understand your question properly, you will have 10 strings in parallel.Choose a module, and note it's power rating (say, 300W).Decide how many modules you are going to use (say 100). Then decide the strings (10). Your total power is 300x100 = 30kW. So you need inverters enough to cover 30kW. You can select one 30kW inverter, three 10kW inverters, or any other combination that works.Good luck! Link to comment Share on other sites More sharing options...
