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.
- 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.
- 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.
- 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.
- 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.
- 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.
Swap an inverter or restring a roof and the sheet is marked out of date, then regenerated from the design.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.

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
The legend, the notes, the tables and the title block stand in this strip; the drawing takes the rest of the frame.
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.
From the 3D design. Once inverters are configured and the strings are assigned in panel placement, the Single Line Diagram button opens the editor with the diagram already generated. If the design has no inverters or strings yet, the editor asks you to finish that step first.
Five findings on the drawing: string Voc above the inverter input limit, string Vmp below the inverter minimum, MPPT current above the limit, an unconnected component, and a string with no path to the grid. A sixth check applies the busbar 120% rule.
The sheet records what it was drawn from, such as inverter models, MPPT counts, string lengths, the panel model, the battery and the grid connection. When any of that changes, the sheet is marked out of date and regenerated. Components you added by hand are kept.
Yes. Save title block templates with your logo and fields such as project, date, revision, drawn by and approved by, and set one as the default. Templates are shared with everyone in your company.
PDF, printed from the sheet, and DXF for CAD. DWG files cannot be imported: the diagram is generated from the design, not traced from an existing drawing.
No. Ratings such as breaker current or battery capacity are values the engineer enters on each component. SolarVis checks string voltages and MPPT currents against the inverter limits, but cable sizing and protection selection stay with the engineer.
No. It is a standalone drawing sheet, exported on its own and kept separate from the customer proposal.
It is included from the Grow plan upward, with no separate add-on. See the pricing page for plan details.
