Please note - if you have a three phase connection and are replacing a single phase inverter with one greater than 3kVA, you now need to apply for approval. This is because, the new inverter will not operate at optimal efficiency.
Cyclone Seroja update
You need Western Power approval if:
you are installing a new solar system, or relocating an existing solar system, or changing or upgrading an existing system or replacing an inverter.
But if you are doing like-for-like maintenance work or only changing PV* panels, then no application is required.
Like-for-like maintenance work means it has the same maximum power rating, same phase, same quantity and/or has a Western Power approved battery (current CEC approval and volt var, volt watt, IEC 62116).
For all other work you will need to apply via our application page.

*PV stands for Photovoltaics otherwise known as solar panels
