Hi Rex,

From the error message you have shared, I assume you are performing photovoltaic modeling using blocks from the “PV Array” library in Simulink and encountering the specified error during model simulation. The most common reasons for this error could be:

• The model equations are forming a positive feedback loop that diverges over time. This could be due to a modeling error, or the system modeled is actually unstable.
• If using a fixed-step solver, the step size might be too large to accurately capture the system dynamic.
• There is a division by zero causing a “Inf/NaN” to enter an Integrator block

You can refer to this blog post for more details and tips to debug this error:

Hope this is helpful.
