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)

This one may be your solution:

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

What should be the value of capacitor??

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.
