Solar single-line diagram maker
Build a simplified solar single-line diagram: panel strings, combiner box, inverter, distribution board and metering in a linear layout, with voltage and circuit-type labels. Great for learning, quoting and presenting an idea; the official single-line diagram of the project remains the job of a qualified professional.
Ready-made on-grid, off-grid and hybrid templates
Start from a template and adapt it to your case: on-grid system, off-grid system, hybrid inverter with battery and home backup. Each template has a page that explains how the system works. See all templates.
