Electrical layout view

The Energy system designer offers two views of the same design. Use the view selector at the top of the canvas to switch between them:

• 3D view — the interactive 3D scene with drawing tools, terrain, and shadows. See Using the 3D map document.

• Electric layout — a schematic single-line diagram of the plant's electrical hierarchy. Covered in this article.

Both views show the same design. Any change you make in one is reflected immediately in the other, and in the main navigation menu.

Note: The Electric layout has no drawing tools. Segments, restricted areas, and shading objects are created in the 3D view.

Reading the diagram

The diagram renders your plant top-down, from the grid connection to the arrays. Node symbols follow IEC 60617-style convention, so the diagram reads like a schematic your engineers already recognize.

Reading order, top to bottom:

1. Grid connection

2. Power transformer(s) — omitted when the design has none; inverter transformers then connect straight to the grid busbar

3. Inverter transformer(s)

4. Inverter setups (individual inverters)

5. MPPTs and the arrays they serve

Node labels

Each node carries its key parameters inline, so you can audit the design without opening every component.

Selecting and editing components

Selecting a node opens its properties in the panel on the right — the same panel you use in the 3D view, with the same settings. Every change updates the diagram in real time.

Right-click any node to open its context menu.

Reconnecting a component

Reconnect lists every valid parent with its voltage and rating, and marks the current one with a check. This is where you connect an inverter setup to a different inverter transformer, or an inverter transformer to a different power transformer — including bypassing the power transformer and connecting straight to the grid.

1. Right-click the component and hover Reconnect.

2. Select the target from the list.

Note: You can do the same from the properties panel — the Electric Layout section has a Connected to dropdown.

Reconnecting triggers a full recalculation of the affected branch. Transformer ratings set to adaptive are resized, and cable lengths are recalculated to match the new connection. A progress message appears while this runs, and Save is unavailable until it finishes.

Important: All inverter transformers connected to one power transformer must have the same age. See Transformers and grid connection.

Moving a component

Move repositions the component physically on site — it does not change where the node sits in the diagram. Because the Electric layout has no map to drag on, position is entered numerically.

1. Right-click the component and select Move (M).

2. Choose a Shift method:    

   • Deltas — enter dX and dY in metres, relative to the current position.

   • Polar — enter distance and angle.

   • Coordinates — enter the target latitude and longitude in degrees.

3. Click Move to apply, or Cancel to discard.

After the move, the component's Position switches from Adaptive to Manual and shows the new coordinates.

Note: If auto-update design is switched off in Settings, an UPDATE DESIGN button appears after the move. The diagram, cable lengths, and transformer ratings are recalculated only once you click it.

Working with large plants

On a plant with hundreds of identical strings, repeating inverters and MPPTs would make the diagram unreadable. Consecutive components with an identical configuration are therefore collapsed into a single grouped node, labelled as a range — for example A.1 – A.7 or MPPT 2 - 3. Components that differ stay separate: in the example below, A.8 is shown on its own because its DC/AC ratio and string count differ from A.1 – A.7.

Use the expand button above the canvas to show every grouped node in full detail. The button then switches to collapse, returning the diagram to its grouped form.

Tip: Expanding affects all groups at once. On a large plant the expanded diagram is wider than the canvas — pan and zoom to navigate it.

Voltage mismatch indication

When a connected component's output voltage doesn't match the busbar it feeds, the busbar turns red. You don't need to check across the whole tree — the diagram flags the error as you build.

To clear it, correct the voltage — either set the component's Output voltage back to Adaptive, or enter a matching value manually. The busbar returns to black as soon as the voltages agree.

Note: Voltage consistency is also checked by Energy system validation, which runs automatically on every save.

Saving the diagram as SVG

Use the Save electrical layout as SVG button above the canvas to export the diagram as a vector file — sharp at any zoom level, and ready to drop into a presentation, a report, or another tool.

Note: No project activation is required for this export. It is also available from File > Export > Electrical layout (.svg).

Limitations

• Not a permitting-grade drawing. This view shows the electrical hierarchy as a decision-support diagram. Full IEC 60617 protection symbolics (disconnectors, breakers, earthing switches) are not part of this view.

• Individual inverters and MPPTs cannot be selected. Selecting either one selects the whole related inverter setup, including any grouped nodes it spans.

• Grid connection, power transformers, and inverter transformers cannot be duplicated — only one of each can exist in a design.
