Connecting Battery Storage

This page is for battery only installations. If you are connecting solar or another form of electricity generation, please apply here

Step 1: Before you apply 
Check the inverter you are installing has been pre-approved for connection to our network. If the inverter you want to use is not on our approved list, your application may take longer to process. See our full list of inverters and technical requirements.

Step 2: Apply
Apply using our application form. Please email the completed form to: DGInfo.Applications@vector.co.nz. The application form must be completed by the home owner, or a person authorised to act as their Agent.

Within two business days of receiving your application, we will acknowledge receipt of your application (in writing) and send you a reference number.

Step 3: Application acceptance/delay
Within 10 business days of receiving your application we will review your application and advise in writing if your application is approved.

Your application may be delayed in processing if:

  • your inverter does not meet our technical requirements; and/or
  • the information provided in your application was not complete

If your application is delayed because of incomplete information, we will notify you. You will then need to provide us with the outstanding information within 10 business days.

Step 4: Testing and inspection for Certificate of Compliance
Within 10 business days of receiving our approval to connect your battery, the equipment must be tested and inspected by a suitably qualified person who can issue a Certificate of Compliance (e.g. a qualified electrician). You must also give us two business days' notice of the testing and inspection date as we may want to send a qualified person to observe. To find a suitably qualified person you can contact www.ecanz.org.nz/.

On completion of the testing and inspection, you must provide us with:

  • A copy of a signed Certificate of Compliance outlining the scope of the installation (including reference to compliance with AS/NZS 4777.1, AS/NZS 4777.2 and AS/NZS 3000); and
  • A documented schedule of the final voltage and frequency protection settings applied to each inverter.

Note - If your installation is unsafe, non-compliant, or your application is incomplete, we reserve the right to disconnect your point of connection to our network until the battery installation is either remedied or disconnected.
