  1. 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.
  2. For even number strings, it's easy enough: Nb. of modules in parallel = 2; Nb. optimizers in series = String length/2 For odd number strings, what would be the best way to model them in PVsyst? (2 modules per optimizer, with the last optimizer having 1 module) I can't add a subarray with Nb. of modules in parallel = 1, and then add the missing modules, as there must be 14 optimizers in series. More about the system: Modules - Hanwha Q.PEAK DUO L-G6.2 430 Optimizers - SolarEdge P860 Inverters - SE33.3K-US Any tips or tricks that have worked for people in the past?
