Anti-Islanding Test
Anti-Islanding Testing is essential in electrical power systems and renewable energy sources, such as PV solar systems, that generate power using inverters.
Anti-Islanding Test for Solar Systems in Australia
Is your solar system fully compliant with Australian safety standards? At Aussie Solar Tech, we offer reliable and certified anti-islanding tests for residential and commercial solar systems across Australia. Whether you’re installing a new system or updating an existing one, anti-islanding testing is a crucial part of grid connection compliance.
We make it easy for homeowners, solar installers, and businesses to stay up to date with network regulations and keep their systems running safely.
What Is an Anti-Islanding Test?
An anti-islanding test is a safety test performed on a solar inverter. In On-grid solar system, it checks that your solar power system can shut them off and the inverter disconnect them from the grid during a power outage. When a power outage occurs, your inverter must stop feeding electricity back into the grid. If it doesn’t, your system can create a dangerous situation for utility workers who might be repairing power lines. This is called Anti-Islanding, and it’s a serious risk. The anti-islanding function ensures your solar inverter disconnects automatically from the grid during a power loss. This test confirms that your inverter’s protection system is working as required in your on-grid solar system.
Why Is Anti-Islanding Testing So Important?
An anti-islanding test is not optional. It’s a mandatory safety requirement enforced by energy distributors and electricity providers. If your system fails this test, you could be disconnected from the grid or refused permission to connect your new system.
Here’s why this test matters:
- Protects lives – Prevents electrocution risk to lineworkers during outages
- Ensures compliance – Required by all DNSPs (Distributed Network Service Providers)
- Maintains system performance – Verifies inverter safety functions
- Supports approvals – Required during grid connection or system upgrades
- Avoids fines and delays – Stay compliant to avoid costly issues
When Do You Need an Anti-Islanding Test?
You may need this test in several situations:
- 🔌 Installing a new solar system
- 🔄 Replacing your solar inverter
- 🔧 Making changes or upgrades to your system
- ⚡ After system faults or failures
- 📄 When requested by your DNSP (such as Ausgrid, Endeavour Energy, Essential Energy, etc.)
- 📆 As part of a routine solar maintenance program
- In some areas, like the ACT, anti-islanding tests are legally required at specific intervals, such as every 5 years. We always recommend our customers to regular testing and maintenance of your system even if they not in Canberra.
If you’re unsure whether you need the test, our team can help you check your local DNSP requirements.
