Derivative State 1 error with a PV array

I am using a PV array and i keep getting an error :'' Derivative of state '1' in block PV/array/diode/Rsh/Bal/Transfer FCN at time 0.0 is not finite.
I use a average buck-boost model (current and voltage source instead of switch and diode). When i run it without these sources it works. When i run with them i have the problem described above.
What can i do about it please?

Hey Jordy,
I am getting the same problem. If you've already got the solution for this problem can you share it with me.

i also got this type of error
Derivative of state '1' in block 'flowermodelmppt/PV Array/Diode Rsh/BAL/Transfer Fcn' at time 7.5E-7 is not finite. The simulation will be stopped. There may be a singularity in the solution. If not, try reducing the step size (either by reducing the fixed step size or by tightening the error tolerances)

A capacitor needs to be connected in parallel before the inductor to counteract the differential link of the inductor. Just like this:

Man, thank you so much!! You have no ideia how you helped me in my undergraduate thesis. i've been struggling with this thing for the past days.
