Single line diagram

Solar single line diagrams, drawn from your design

From the PV array to the grid connection, solarVis turns your 3D design into an editable diagram. Electrical checks run as you draw, and the sheet ships with your title block as PDF or DXF.

Everything the electrical sheet needs, drawn from the design

The single line diagram is not a separate drawing job. It is built from the 3D design you already finished, checked against the inverter limits as you edit, and laid out on a sheet ready to hand over.

  1. 01

    Generated from the 3D design

    Finish the 3D design and the diagram builds itself: PV array, MPPTs, inverters, battery and the grid connection, already wired. Nothing the design already knows has to be drawn again.

  2. 02

    Electrical checks as you draw

    String Voc above the inverter input limit, Vmp below its minimum, MPPT current over the limit, unconnected components and strings with no path to the grid are flagged on the sheet, along with the busbar 120% rule.

  3. 03

    Around 40 electrical symbols

    Fuses, isolators, breakers, RCDs, surge protection, combiners, meters, busbar, generator, export limiter and more. Every connection point carries its domain (DC, AC, earth, measurement, comms), so an incompatible wire cannot be drawn.

  4. 04

    A real drawing sheet

    A4 or A3, landscape or portrait, with a title block, a legend of the symbols on the sheet, notes, a revision table, and PV module, inverter and system summary tables. Caption height is checked against ISO 3098.

  5. 05

    PDF and DXF export

    Print the sheet to PDF for the grid application file, or export a DXF and keep working in your CAD tool.

The design changes, the diagram follows

Swap an inverter or restring a roof and the sheet is marked out of date, then regenerated from the design. Components you added by hand stay where you put them, so a design change never means redrawing the whole diagram.

From 3D design to a sheet you can hand over

· 01

Catch the wiring error on the sheet, not on the roof

Every string is checked against the inverter it is wired to while you edit. A string whose Voc exceeds the input limit, an MPPT carrying more current than it accepts, or a component left unconnected shows up as a finding on the diagram. When everything is in order, the sheet shows that the checks passed.

  • String Voc and Vmp checked against the inverter voltage window
  • MPPT current checked against the input limit
  • Unconnected components and strings with no path to the grid flagged
  • Busbar 120% rule on the AC side

Your title block, on every drawing your team sends

Build your company title block once: logo, project, document, date, revision, drawn by, approved by, customer and address. Split cells into rows and columns, set the font per cell, and mark one template as the default. Templates are shared with everyone in the company, so every engineer sends the same sheet.

  • Logo plus free and auto-filled fields
  • Cells split into rows and columns, font per cell
  • One default template for the whole company
  • Revision table and notes on every sheet

Hand it over as PDF, or keep working in CAD

Print the sheet to PDF for the application file, or export a DXF with the text styles of each typeface preserved, and continue in the CAD tool your office already uses. Mark changes with a revision cloud and add notes directly on the sheet.

  • PDF print of the full A4 or A3 sheet
  • DXF export with text styles per typeface
  • Revision cloud and free text notes
  • Custom component for anything outside the symbol set

Questions about the single line diagram

A single line diagram (SLD) shows the electrical path of a PV system with one line per circuit: strings, protection devices, inverter, metering and the grid connection. Installers, engineers and grid operators use it to see how the system is connected.
