Simulink PV array block output NaN

I am trying to simulate MPPT using a fuzzy logic controller. I am new to simulink and I tried to use the PV Array block from Simscape/Electrical. The problem I have with this block is that when I run the simulation, the voltage and the current at the output of the PV Array are NaN, except for a very short period of time at the beginning of the simulation.

I tried to simulate the PV array block alone and I get the same problem, even if I connect a voltage measurement at +- terminals the result is still NaN. I also checked the box for breaking the algebraic loop but my problem is not solved.

If anyone has an idea how to solve this problem I would be grateful, I have not found someone with the same problem so far.

Thank You!

Any answer for this problem? i got the same issue

I have the same irritating problem. For me using variable time step solver is not an option.
