Hi Everyone, I am experiencing a configuration issue while simulating a system with multiple inverters and MPPT inputs in PVsyst. Here are the details: - System Configuration: Inverter 1: 5 strings of 20 panels in series and 5 strings of 18 panels in series, totaling 10 strings. The inverter has 12 MPPT inputs. Inverter 2: 4 strings of 20 panels in series and 4 strings of 19 panels in series, totaling 8 strings. The inverter also has 12 MPPT inputs. - Issue: The error message states: "The sum of the MPPT inputs in the sub-arrays is not a multiple of the number of inverter MPPT inputs." PVsyst interprets the configuration as using 1.5 inverters instead of two separate inverters if I did not used MPPT Sharing. Could you please provide guidance on how to configure PVsyst to accurately reflect the use of two inverters, each with their respective string configurations and MPPT inputs? Thank you for your assistance.

I am doing a project where I tried to do the simulations with the power-sharing to distribute power equally among the MPPT but I am getting below error "The sum of power shares is larger than 100%". I have attached the images for your reference. First snip shows the list of sub-arrays and system equipment. Below snip is after the power-sharing defined No error in the system after power sharing is done. I can simulate the system without any error But when I go back to the project page I get the error "The sum of power shares is larger than 100%" Please see the below snip. Now, if I go to power-sharing again percentage is changed for each MPPT, and Pnom ratio is uneven instead of equal or near to equal. Now If I uncheck and check, power sharing works fine but sharing is not retained after simualtions. As of now, I have done the simulations with partial sharing but can you please suggest a solution? I can provide more info if needed.

I want to design a solar system (15.48 KW =36 Modules x 430 w per module) on two roof (28 panels on one roof and 8 on other) having tilt angle of 30 and 20 degree respectively at location of 41°18'06.0"N 0°59'17.8"E. I selected Pv module of 430 W and a hybrid inverter (8KW) of Fronius_Symo_Gen24_8_0_Plus.OND (Fronius International) having 2 MMPT inputs. During Design, I configured 18 module in series for 1 inverters and the same for other. Each inverter have 2 MPPT so i have following confusions. 1. Do i need to configure 4 strings (each of 9 module in series) with 1 string for each MPPT or to connect 18 module with one mppt? (Please review snap) 2. Location is Northern hemisphere, so panel should be faced towards south having azimuth angle of 180 degree. But when i select 180 degree, Loss due to Optimum goes upto 42% (snap attached) while it comes 10% when azimuth angle of 0 degree. Why it is happening? 3. What will be azimuth angle in my configuration ? 4. What can be the best configurations ( No of strings and MPPT inverter)? Valuable Expert opinion and prompt response will be highly appreciated, please.. 3.

im only using 4 out of 5 mppt, and in "number of inversor" is just 0.8, not even a full inversor, does it make diference on the simulation??
