WHY IT MATTERS

One document almost every market requires — still drawn by hand.

Single Line Diagrams are required in almost every country and region, either to comply with local regulations or to obtain permitting documents and grid connection approval.

Creating them manually is usually time-consuming and error-prone — and a single missing detail can hold up an entire project.

  • 01Installation document

    Guides installers on-site on how to wire the system — which device connects to which component.

  • 02System manual

    A core part of the system manual, which must be available on-site at every installation.

WHY ETURNITY EXPERT

From project data to compliant diagram — automatically.

Because the diagram is generated from your existing project, there’s nothing extra to maintain, and nothing to forget.

A huge time saver
What used to take hours of manual drawing is generated almost fully automatically — a genuine step change for daily project work.
No separate software required
Skip the extra licence for dedicated SLD tools. One platform, one source of project data, one diagram that's always in sync.
Fewer errors, fewer iterations
Getting every detail right by hand is hard under daily pressure. Automation removes the small mistakes that cause delays and rework — including grid connection permits that stall on a faulty diagram.
One connected process, start to finish
Single Line Diagram, string plan and roof plans work together end to end — no time-consuming handover from sales to project manager or planner.
A huge time saver
What used to take hours of manual drawing is generated almost fully automatically — a genuine step change for daily project work.
Built for PV — not generic CAD
A symbol library focused on what a PV system actually needs, so you spend time on the project — not learning a CAD tool.
Ready when you need it
Generated from live project data — update the design, and your diagram updates with it.
Three steps from project to compliant PDF.

1. Your project data is already there

Modules, inverters, strings and components are already defined in Eturnity from planning — nothing to re-enter.

2. Eturnity draws the diagram

The Single Line Diagram is generated automatically, matching your most current project data — on a true drawing canvas, not a rigid template.

3. Fine-tune and export

Adjust freely where needed, then export a titled, submission-ready PDF for permitting, grid connection or the system manual.
Competitive advantage

Automated. Yet still flexible.

Most tools force a trade-off between speed and control. Eturnity’s Single Line Diagram is built on a true graphical canvas, so automation never comes at the cost of flexibility.
