Hi,
If I change the temperature in OND file of the inverter the production doesn't change at all. It should derate with respect to the derating temperature. In red it is written this strategy can be modified in the project area Miscellaneous Tools (inverter temperature tab). Can you please guide me where is this project area Miscellaneous Tools (inverter temperature tab).

Hello,

If the OND file was properly updated to include a temperature de-rate, please verify your weather file contains temperatures during production hours which are higher than your de-rate in order to see temperature-related clipping. Assuming this is an outdoor installation, the inverter temperature for nominal power evaluation should be checked to external ambient temperature (which is default) for grid-connected systems.

Miscellaneous tools is renamed to Energy Management in new PVsyst versions.
