About this gig
Is your solar or off-grid system missing clear, professional documentation? I design accurate wiring diagrams in draw.io that are ready for real installation not just pretty drawings.
I work with systems based on Victron, SMA, Renogy, Fronius, and other major brands.
I can help you with:
- DC and AC wiring diagrams for solar, RV, and off-grid systems
- Inverter, battery, busbar, and MPPT layouts
- Cable sizing, fuse selection, and protection devices
- System upgrades, redesigns, and troubleshooting documentation
You will receive:
- Clean, easy-to-read diagram drawn in draw.io delivered as PDF + editable .drawio file
- Practical, installation-ready layout
- Correct component sizing and safe design
Why work with me? I have 6+ years of hands-on experience in electrical installation and PV systems. Every diagram I deliver is based on real-world knowledge not just graphic design.
I use draw.io to deliver fully editable diagrams so you or your installer can update them at any time.
