how can I overcome on algebraic loop in simulink

I faced error in simulink when I use PV-block that located in renewable library which developed by mathworks team- with inverter (power electronic) with powergui block (discrete mode time =1e-6) and the PWM in the inverter (5Khz)
I tried to install memory block and unit delay block around the error area which is in ( PV Array/Diode Rsh/Product5 ) but it doesn't work still the same problem
I tried to minimize the sampling time in powergui from 1e-6 to 1e-8 , it works but it takes very very long time even if the simulation stop time is 0.1 unit time
if anybody can helps me .... please i'm trouble

Basialy algebric loop error occure in simulink model whenever zero is come in denomenator part of any function.
To ovecome the algebric loop error in simulink model due to -: PV Array/Diode Rsh/Product5.
follow two steps;
In this way your problem will be solved.

- This issue might occur when you are using the integrator block with 0 initial condition, try changing the initial condition to 0.0000001 instead.
- Else, you could also try changing the Solver to ODE15s (stiff/NDF) under the Type : Variable Step in the Model Configuration Parameters/Solver/Solver Options
Hope it helps!
