Dear Sir,

From this viewtopic.php?f=19&t=485 topic I understand that, PVSYST can not give inverter output based on internal inverter temperature.

But is it possible for PVSYST to give inverter output based on ambient temperature?

Not in the present time.

Using this in the simulation would only be possible outdoor (otherwise we have to estimate the room temperature).
It would imply 2 additional parameters :
- The internal temperature increase as function of the instantaneous power
- The PMax power derate as function of the internal inverter temperature.

Did you ever see these parameters in the inverter datasheets ?
