Improvements

Voc Derivation Improvement (Version 12 only)
Previously, there were edge cases for certain modules in which the single diode model derivation of Voc would not converge under specific weather conditions. We have kept this Voc derivation process exactly the same. However, if the existing model does not converge, a new process is initiated which searches for a valid Voc with smaller voltage steps and increases the likelihood of finding a valid Voc. This update is applicable to V12 only.

Version 12 DC Field Nodal Data has been corrected to resolve an issue where the column data was not matching the column headers after column ‘AI’.
Corrected an issue in MapBuilder where the target DC/AC ratio from the UI was not being used correctly for partial array blocks when the Custom Array Editor is enabled. Going forward, the DC/AC ratio in the Custom Array Editor will be used for all full arrays and the target DC/AC ratio in the UI will be used for all partial arrays when the Custom Array Editor is enabled.
Disabled decimal rounding within the BESS Cycling Degradation input field.
Corrected data mapping for weather files retrieved from Solcast API. This was incorrectly implemented in release 12.11.0 when new features were added.

Integrated Pile Configurator Access
Users can now open the Pile Configurator directly from Terrain Pro. Project data is automatically passed to the configurator, and any edits made to pile properties are saved in real time. When users return to the configurator, their work is preserved—no more restarting from scratch.
Add CAD Data to Company Projects
Users can now upload and associate CAD files (e.g., DXF,PVCase BOM or csv extracted from CAD) within their company projects, enhancing collaboration and project documentation.

TT Axis Max Slope in Summary Reports
The maximum TT axis slope value is now correctly populated in both the on-screen Summary Report and the downloadable Excel file.

BESS Input Field Added
A new Battery Energy Storage System (BESS) set of inputs is now available, supporting energy simulations with BESS. The same BESS inputs from PlantPredict are mirrored in Design Pro.
Layout Cloning Enhancement
When cloning an existing simulation, the layout data is now carried over to the new simulation—eliminating the need to re-run the GCR-Capacity process.
