Installation Tips
- Mount panels on roof — Use Z-brackets for rigid panels
- Wire in series — Keeps voltage low, amps high
- Fuse everything — 10A fuse between panel and controller
- Use 6mm cable — For runs under 5 metres
- Label all wires — Critical for troubleshooting
- Seal all roof penetrations — Dicor sealant recommended
