Release notes 4.0.1

Update Date: 2026-01-12

Update highlights:

1. Create zones - Automatically create zones: allows for the creation of new zones based on existing arrays, which can be used in situations where no PV zones have been set up after reverse import

2. The new algorithm for auto connection of RS485 cables ensures a hand-in-hand connection, while supporting control of the Qty. of devices per 485 circuit within a specified quantity range

3. Cable list: The margin factor for low voltage cables can be set segmented according to length

4. When placing the first Middle Voltage Point, the azimuth angle can be modified. When placing consecutively, the system will automatically capture and place the Middle Voltage Point with the same azimuth angle according to the X and Y interval distances

5. Add the function of adjusting the height above ground of the combine device for the selected, this block, or all blocks

Update Description:

1. Project settings

Special characters are supported for input in Item Remark, and the left and right spaces will be removed when submitting the longitude and latitude

2. Create terrain

Satellite map interface - Imported KML supports areas composed of Ovital Paths (previously only supported regions)

3. Create zones

Auto create zones - newly added based on existing arrays

The "Delete" button in the Layout zone list can also be used to delete the Layout zone where the arrays has been placed

4. Array layout

Fix error: When there is half-string arrays in the array imported in reverse, it may lead to the loss of combine information

When conducting alignment in a single Layout zone, the maximum threshold for initiating Optimization has been expanded from 4000 Arrays to 40000 Arrays

When the main array is set to Tracking, horizontal N-S axis, if you select variable pitch, a tip will be displayed indicating that it is not supported and the operation will be returned; if you select fixed pitch, the pitch will be calculated based on the average slope angle and aspect of the layout zone, as well as the rotation angle of the Tracking, horizontal N-S axis at the start and end times (without considering backtracking)

After checking "Azimuth according to slope direction", in some cases, when the terrain aspect is not within the set azimuth range, there is a bug that the arrays are not placed according to the azimuth closest to the set range

5. Pairing half string

Relevant bug fixes

6. Combine Divide Tool

The right-click menu has been enhanced with the ability to adjust the height above ground of the Combine device for the selected block, this block, or all blocks

The Combine device is positioned vertically and no longer follows the array base slope

7. View cable tool

RS485 Cable auto connect adopts a new algorithm: ensuring a hand-in-hand connection, while supporting control of the number of 485 devices per round according to a specified quantity range

In the Edit 485 cables tool, add menus for Re-calculate this block/all blocks 485 cables, Clear all connections of this block, and 485 devices per 485 quantity, optimize display and manual editing operations

Modify the bug where the PV cable does not follow the path in special cases

8. MV cable Combine

When placing the first Middle Voltage Point, the azimuth angle can be modified. When placing consecutively, the system will automatically capture and place Middle Voltage Points with the same azimuth angle according to the X and Y interval distances

When AUTO wiring, the newly added grid point is placed according to the azimuth and pitch setting values of the existing points

9. Flexible Rack

Some known bugs have been modified

10. Cable list

The margin factor of low voltage cables can be set segmented according to the length

When exporting the Cable list, check the 485 cables of each block and provide a Tip to modify them

11. Yield Calculate

When the arrays have no associated PV module, let user enter the Temper. coeff. of Pmpp

Correct the issue of excessive shading loss in wind turbines and houses

12. Candela3D Shading Object

Fix the issue where no collision occurs when placing a Tree/Cube, but error message pop-up

13. Adjust E-W space of arrays

When there is a slight deviation in the Array azimuth, the issue of not being able to adjust the E-W space arises

14. Move/copy power blocks

After moving/copying power blocks, immediately update the legend in the top left corner

15. Synchronize with CAD

Solve the problem of discontinuous polylines imported from CAD

16. Other

Prevent the app from crashing when the button is clicked before loading is complete

User settings - Fix issues related to modifying the Device size of the Combine device
