What is anti-islanding and why do you need to test if your inverters anti-islanding protection is working?
In electricity distribution terms, “islanding” is where part of the mains grid is isolated from the normal supply and powered by another source.
Uncontrolled islanding creates dangers for electrical workers since areas they assume are safe to work on may become energised.
Uncontrolled islanding also can create hazardous situations when the supply is reconnected. Low power quality in the island can also damage electrical equipment connected to the island
All inverters installed in Australia must have anti-islanding protection.
If the inverter detects that the grid is not within normal parameters, it will stop sending electricity into the grid in order to prevent the formation of an uncontrolled island.
How will my system be tested?
We are Clean Energy Council accredited PV solar system installers and therefore are qualified to undertake the periodic anti-islanding testing requirements outlined by Evoenergy.
The normal operation of the inverter will be verified, and then the inverter will be disconnected from the grid
The inverter should detect this condition and stop sending electricity into the grid. The electrician will monitor the output voltage of the inverter to confirm that it is not energised once the grid is disconnected.
We’ll capture all the necessary data and lodge the required Evoenergy paperwork.
The standard price for a residential solar system anti-islanding test within the ACT is $150.00 (GST Inclusive) per solar inverter. Other pricing will be negotiated if you have more than one solar inverter.
