tecnun Posted February 3, 2021 Share Posted February 3, 2021 Hello, good dayI have a problem with a common configuration: 15 strings per inverter with a 12 MPPT (24 input) string inverter (Sungrow eg). It shows up a message like this : <<9278 inputs with 1 string and 2966 inputs with 2 strings, consider disabling "use Multi-MPPT feature" for ensuring power sharing on each input>>2 involved problems:1- It takes 90 minutes to simulate whilst without this Multi-MPPT activation it takes less than 30 seconds2- It applies more than 9% of overload lossesIs there something wrong? These configurations are usual, as it results quite "lucky" that you can fill out all the 12 MPPT with 2 inputs per MPPT (24 inputs)Please we need some feeback or related question if you guys need more detailsBR Jose (Madrid,Spain) Link to comment Share on other sites More sharing options...

Linda Thoren Posted November 2 Share Posted November 2 The warning message in orange suggests considering disabling “use multi-MPPT feature” for ensuring power sharing on each input. With all the strings being the same there is no need to activate the multi-MPPT feature. In this case, the number of inverters is 1020.3 and thus do not reflect a correctly sized system in reality.
