Pv model error simulation Nonlinear solver: Linear Algebra error

I have a problem with my pv model,here is ths model :

 when I run the simulation i got this error : Nonlinear solver: Linear Algebra error. Failed to solve using iteration matrix. Initial conditions solve failed to converge. Equations of one or more components may be dependent or inconsistent. This can cause problems in transient initialization. Here is the set of components involved: 'modelcell1/Current Sensor1'

Please can anyone explain to me what to do to solve this problem. Best regards
