power factor（cos phi）-The set value differs from the calculated result.

[jack chen]

I have a question regarding the power factor. I set the power factor（cos phi） to 0.9 in PVsyst Version 7.4, but the energy flow diagram in the calculation result report shows it as 0.894. I would like to know the reason for this discrepancy.

"I want to know whether such calculation results are normal and what the reasons for such differences are？
