Hi Paul,

Can SAM model the effect of system POI power limit on array voltage? Meaning can SAM show the inverter power tracking to raise array voltage due to AC power curtailment?

If not, is this capability planned for the future?

Much appreciated,
Ben

Hi Ben,

When the array DC power output exceeds the inverter DC power rating, SAM sets the inverter output power to the inverter AC power rating. It does not adjust the array voltage.

This approach ensures that the AC output power is represented correctly.

Please feel free to make a feature request on the SAM repository on GitHub.com: github.com/NREL/SAM/issues

If you prefer not to create a GitHub account, let me know and I will make the feature request.

Best regards,
Paul.
