Inverter system with capacity up to 10kVA per phase

Use this form if you're installing an electricity generating system (such as solar panels) that will feed the Western Power network through inverters. 

You need to submit a new application if you want to add to, change or relocate your inverters or batteries, or add another generation source.

Who can apply?

As the electricity account holder, you are responsible for the connection of your system to the Western Power network. However, you may authorise your system supplier to apply for you, so please check with them to confirm what action you need to take.

How long will it take?

You will received a response typically within an hour of submission. Most applications are approved but some require more assessment - please allow 15 business days.

How much will it cost?

There is no fee for this application. However, your electricity retailer may apply a charge e.g. for updating your meter.

What will I need to complete this application?

• Retailer reference number: Discuss your plans with your electricity retailer. They will advise you on how your system will affect your electricity account and meter. Your retailer will provide the retailer reference number (RRN) you need when you apply to us.
  
  
• Technical details of your system: You will need to know the technical specifications of the equipment that you already have connected as well as the equipment that you now wish to add.
  
  
• If your connection is a shared connection, as is common for strata developments, shopping centres and commercial tenancies you will need to consult with your management body.

What is technical assessment?

Systems which meet certain criteria such as having energy storage; inverter capacity over 5kVA; generation other than PV panels or a non-standard connection point require further assessment. We will advise you if your application is sent for technical assessment and we may request additional information such as site or single line diagrams.

What happens if my system is approved?

• We will send an approval: When we approve your system we will email the applicant (you and/or your nominated supplier), and inform your electricity retailer. See Conditions of Approval
• Your electricity retailer will update your meter: Your meter may be replaced or re-configured. Ask your electricity retailer for information on how long this will take and what cost is involved. 

Is my meter set up for import/export?

Please contact your electricity retailer to confirm that the meter is set up for import/export.

When can I connect my system?

You need both the following before connecting your system:

• You (or your supplier) have our approval email
• Your meter is set up for import/export

A Notice of Completion must be submitted by the electrical contractor within 3 days of the system being connected.

How do I maintain my system?

Contact your installer or electrical contractor for information on maintaining, repairing or upgrading your system. The Clean Energy Council website also contains useful information.

My application was declined – what do I do?

If your application is not approved, we will provide information on alternative options. These options will help you decide whether to alter your proposed system or to modify your connection point before re-applying for approval.
