Hi Paradesi,

I have faced a similar issue, this seems to be a limitation of the “PV Array” block. I have tried simulating the block under the open cuircuit conditions by following the below mentioned steps:

• Double click on the “PV Array” block.
• Select the “Robust discrete model” checkbox on the “Advanced” tab.
• Set the cell temperature to “25”.

This should resolve the issue.

Hope it helps.

what if i want to change the temperature

Do you want change it during the simulation ?

[PARADESI]

yes

If you want to retain the "Temperature" input, one thing can be done is, instead of checking the “Robust discrete model” checkbox, you can uncheck the "Break algebric loop in internal mode", but it slows the model's simulation speed.
