Traceable topology
Eight strings of 17 modules, four strings per inverter, and one string connected to each MPPT circuit.
Technical drawing sample
Commercial rooftop PV single-line diagram
A controlled A3 drawing for the representative 74.8 kWp rooftop example. It shows the string-to-MPPT allocation, conversion equipment, AC collection, point of connection, monitoring path, and design hold points.
Representative concept - not a completed project. Not for construction, procurement, or energisation.
Drawing sheet
A reviewable electrical architecture with controlled limitations.
The complete representative power and monitoring architecture is presented together with its controlled design notes and project-specific hold points.
Drawing controls
What is fixed, excluded, and still required.
No parallel strings per MPPT
Two strings would produce 26.24 A at maximum-power current, above the representative inverter's published 26 A MPPT limit.
Ratings remain project-specific
Cables, protective devices, fault duty, earthing, RCD, SPD, export control, fire access, and grid settings require verified project inputs.
Project drawing support
Develop a controlled drawing package from verified project data.
Available inputs should include the site layout, equipment data sheets, point of connection, existing SLD, cable routes, fault level, and applicable local requirements.
