Installation & safety
AS/NZS 5033
Installation and safety requirements for photovoltaic (PV) arrays: DC-side layout, isolation, maximum array voltage, earthing and signage.
Ask Watt about AS/NZS 5033
Watt answers from the bench, so it can explain scope, boundaries and where this standard bites on a job. It cannot quote the standard, and it will say so rather than guess.
Applies to
The DC side of every grid-connected and off-grid PV array.
How it meets the others
- Sits underneathAS/NZS 3000The general wiring rules sit under the whole electrical installation; 5033 covers the PV array specifically.
- Where the line sitsAS/NZS 4777.15033 governs the DC side of the array. 4777.1 picks up at how the inverter-connected system is installed for grid connection.
- Applies alongsideAS/NZS 3008.1Cable selection and current-carrying capacity is worked out alongside the array requirements.
- Applies alongsideAS/NZS 5139A battery on the DC side sits alongside the array requirements.
- Product standard behind itIEC 61215Module design qualification is a product-level standard for the modules an array is built from.
- Product standard behind itIEC 61730 (Parts 1 & 2)Module safety qualification is a product-level standard for the modules an array is built from.
- Verified byIEC 62446-1Commissioning verification of the installed array.
- Applies alongsideAS/NZS 4509Stand-alone systems still build a PV array, so the array requirements apply off-grid too.
This page explains what AS/NZS 5033 covers and where it sits against the other standards. It does not reproduce the standard, and it is not a substitute for it. For the requirements themselves, work from the current published edition, available from the Standards Australia store. Compliance is determined by a licensed professional working to the current edition.
