Generate and open the circuit plan

The circuit plan turns the planned components (modules, strings, inverters, optimisers, batteries, wallboxes, meters) into a customer-facing single-line schematic. Once the PV system is correctly strung in the 3D editor (inverter chosen, strings assigned to MPP trackers), Reonic generates a default circuit plan. From there you refine it in Configure (preconfigure) or free-edit mode and export to PDF or image. The saved plan also embeds automatically as an image in the offer PDF the customer receives.

Who this is for

• Installer admins finalising the electrical wiring view that goes to the customer and to the grid-registration submission.
• Account managers reviewing the diagram before sending the offer.
• Anyone who needs the schematic for a residential PV system, with or without a battery, wallbox, or country-specific protective components.

Before you start

• The PV system must be strung in the 3D editor: modules placed, strings created, inverter chosen, strings assigned to the right MPP trackers. The circuit plan reads this state to generate the default schematic.
• Battery, wallbox, heat pump, or any other AC-side component must be planned on the offer if you want it on the schematic. Components missing from the offer don't appear in the generated plan.
• Confirm the offer is still draft / unsigned if you intend to edit. Once a variant is signed, the circuit plan on that variant is locked along with everything else.

When the circuit plan is generated

The first time you open the circuit plan on a variant, the editor builds it from the planned components, so there's no separate "generate" step to run. Each subsequent open shows your saved state. The planned modules, strings, inverters, optimisers, battery, wallbox, and meters map to a single-line schematic automatically.

The diagram is a single-line schematic, not a wiring tray plan, cable-route plan, or structural drawing. It's what the customer sees on their offer PDF and what the installer references when submitting to the grid operator.

Open the circuit plan

From the offer's planning view, open the 3D editor and switch to the strings view (the string-wiring overlay). The Circuit diagram button there opens the generated schematic in a full editor window.

If the diagram doesn't appear, check that the PV system is strung in the 3D editor first. The circuit plan draws from the planned state, so it needs an inverter chosen and strings assigned before it can render anything.

What the schematic contains

The editor renders the components you've planned on the offer as a single-line schematic with:

• Strings with module counts per MPP tracker.
• Inverter with its MPP tracker handles and AC outputs.
• Battery / battery system wired into the inverter (AC- or DC-coupled depending on the inverter and battery selection).
• Wallbox / EVSE tied into the consumer side, with optional integrated load management.
• House connection (point of common coupling) at the grid-side edge.
• Meters: feed-in, consumption, bidirectional, or energy-flow direction sensors.
• DC isolators, AC disconnect, RCDs, surge protectors, circuit breakers as you add them while editing the circuit plan.

Export to PDF or image

The finished circuit plan exports to:

• JPEG: for embedding in custom PDFs, emails, or grid-operator submissions.
• PDF: for direct download as a standalone schematic page.
• Direct save to project files: the diagram is stored as a file attached to the offer's project, reachable from the project's documents tab.

The saved circuit plan also embeds automatically as an image in the offer PDF's summary section. That's the customer-facing render, independent of the manual export above. Save the plan before generating the offer PDF so the diagram the customer sees is your latest version. Resolution depends on the canvas size at export time, so maximise the editor window before exporting if you want a high-resolution export for printing or large-format submission documents.

Hide strings in the preview images

Composing the 3D-planning preview snapshots (hiding strings or other overlays before clicking Add view) is part of the 3D editor, not the circuit plan. See the 3D module-planning guide for that flow.

Note: The circuit plan is a residential feature. Commercial projects do not have a circuit-plan surface, so there's no path to generate, download, or create a circuit plan on a commercial project.
