When does voltage drop actually matter in cable sizing?

For most solar and battery installations, the answer depends on cable length. Based on conservative calculations against AS/NZS 3008.1.1:2025, AS/NZS 5033:2021, and AS/NZS 4777.1:2024, here are the thresholds you need to know:

- PV DC cables: under 40m ✓
- Battery DC cables: under 10m ✓
- Single-phase inverter AC cables: under 5m ✓
- Three-phase inverter AC cables: under 15m ✓

Below these lengths, operational current takes precedence and voltage drop won't govern your cable size selection. Exceed them, and you need to run the numbers.

We've broken down the full methodology, including the worked calculations for each cable type, in our latest technical article.

Last 26 May, we were at the Solar Juice Roadshow, presenting to a room full of solar installers and industry professionals on grid-connect PV systems.

It was great meeting everyone on the day and having such engaging conversations. The energy in the room was a great reminder of how passionate this industry is about getting things right. 🤝

If you're on the Sunshine Coast, we'll be there today! Come along and say hi. 👋
