thanks a lot!

Ok, I know, then , for a correct simulation in PVSyst, is it possible to use "optimizer" to connect modules with different orientations and connect them to a single MPPT? More, using mixing orientation means to connect different orientations modules to the same MPPT? This point it is not clear for me. Many thanks

Thank you, I understand that I can't simulate my system, correct?

Thanks for your reply. If I understand well, you are using 2 strings with equal lenght (2 x 9). My setup is different, 5 orientations with several string lenght. Any chance to accomplish a realistic simulation of following: Many thanks for your help!

Hallo, we have the following case: The inverter has 2 MPPT, and we have 3 different orientations. Then we would use optimizers in PVSyst. But,when we try to go into "power sharing", there we have inverter with 2 MPPT and 3 subarrays/orientations. How could we manage this situation, i.e. simulate 3 orientations with a 2 MPPT inverter? Thanks a lot

this is the situation about power sharing using optimizer option for the first 2 strings

Clear, but I have 5 orientations and 4 inverter MPPT. Then, must I use optimizer? And in this case, how I can assign two different orientations (with modules optimizers) to the same MPPT ? Tnx

ok, right, now I set 1 MPPT for each subarray, always 5 orientations. How could I go ahead to fix the system? Many thanks

Ok, thanks. I tried an inverter with lower power. Now, the sum of my subfields is 44.16kWp and my inverter is 40kWac rated power. Anyway, I don't understand how to assign the various strings to inverter inputs using "power sharing". Now, I have 5 strings with 5 different orientations, as per attached image. Within red lines the problems I'm facing. Could you suggest any solutions, please? Many thanks

Hello, I'm working on a system that has serveral orientations using an inverter with a sufficient number of MPPT, but... I have 5 orientation, inverter that I have to use has 10 MPPT. Then, using power sharing I had to change MPPT number in inverter model because PVSyst don't allow empty MPPT. Power sharing is ok, but PVSyst returns an error message about inverter ovesized. I would use a single 100kW inverter with 10 MPPT (I changed to 7 MPPT) for all the "Tetto" subarray. How can I solve this issue? Many thanks
