Labelling a Grid Connected Battery Installation
AS/NZS 5139 and AS/NZS 4777.1 between them ask for a lot of labels on a battery system — and inspectors see them missing, wrong or in the wrong spot every week. This course shows you exactly what’s required, including systems with backup supply modes.
A missing or incorrect label won’t stop a battery working, but it will stop an inspection. Labelling failures are among the most frequent defects on battery installations, partly because the requirements are spread across two standards and partly because the situational labels — backup circuits, alternative supply, hazard points — are easy to overlook.
This course brings it all into one place. You’ll learn the mandatory labels for every grid-connected battery, when additional labels are triggered, how to label backup circuits, isolators and hazard points correctly, and how to keep the result clear, durable and professional without cluttering the switchboard. It comes with our free Battery Labelling Checklist to take on site.
What you’ll learn
- The mandatory labels for every grid-connected battery system under AS/NZS 5139 and AS/NZS 4777.1
- When additional or situational labels are required — and when they aren’t
- How to label backup circuits, isolators, alternative supply and hazard points correctly
- How to choose labels that stay legible and attached in the weather
- The labelling defects that most often fail an inspection, and how to avoid them
Course content
Why battery labelling matters
The two standards involved, and what inspectors are looking for.
Mandatory labels for every battery system
Danger, warning and system-identification labels, and where each one goes.
Situational labels
Backup and alternative supply, shutdown procedures, hazardous DC voltage and multiple-supply warnings.
Presentation, durability and common defects
Label quality, clarity without clutter, and the mistakes that get systems sent back.
This course includes
