Show Cable route

Show the PV string cable

After clicking the tool, the bottom left corner prompts to select the power block.

After selecting the power block (wait a few seconds), the cable wiring of the power block will be displayed, as shown in the following figure:

If you need to show the cables of a single string, simply click on it. Click on the blank area to return to view all strings cables.

The red cross indicates the cable's voltage drop exceeds the threshold, which can be adjusted through cable routing or combiners/inverters's position.

Show the devices's cable

After entering the interface shown in the figure, click on TABLE to switch to the level.

Cables that voltage drop exceeds the threshold will be marked with * * before their tags.

Check the third level combiner cable (if any)

After entering the interface shown in the figure, click TABLE twice to switch to the third level.

Modify string and combiner device tags

When showing cables, left click to select string/combiner device, right-click menu "Modify number".

Force along cable path

When the cable takes too many detours along the user-defined cable path, it will abandon the cable path. If you need to force following the cable path, One or two of the following two parameters can be increased in "User settings" or "Cable related weight set" in the right-click menu:

Communication 485 Cable

Click on the "Show cable route" tool and press the TABLE key to switch to the "485 Cable" level to view the automatically calculated 485 cables.

The right-click menu allows you to modify the "hand in hand" relationship between devices:

• Right click menu: Modify 485 cable.
• Move the mouse over the connection between two devices, and the connection will turn bright. Right click to delete the connection to remove the "hand in hand" relationship between the two devices.
• Click on two devices with the mouse to create a "hand in hand" relationship between them.
• Press the ESC key to return to view the entire 485 cable of the power block.

MPPT distribution

Electrical connection 3 (String inverter -- Transformer)

• Under the Cable Tools, String - String Inverter level, the right-click menu can distribute the strings of each inverter to a specific MPPT. Main principles:
• Prioritize the allocation of MPPT based on different string types (different module model and qty. of modules per string).
• Allocate MPPT according to the face normal of the string.
• On the basis of prioritizing the above two points, MPPT can be considered for cable length allocation in the string.
• When the string type of an inverter is the same and the orientation difference is within 1 °, if the user chooses not to consider cable length when allocating MPPT, the software will only evenly allocate the string to MPPT.
• After distributing MPPT inputs, three columns of data will be added to the cable list, including MPPT tag, real tilt and azimuth of the string.

Electrical connection 4 (DC combiner -- Power station)

Under the view of cable tools, DC combiners - transformer level, the right-click menu can distribute each DC combiner to a specific MPPT. Main principles:

• Try to evenly distribute the capacity of the combiners to each MPPT in order.
• After MPPT grouping, the results can be viewed and manually adjusted on the legend.
• After MPPT grouping, the device tag can include the MPPT tag (optional in user settings).
