SOLAR CONNECTIONS

 

AusNet Services supports customers looking to connect Inverter Energy systems (IES) including battery and photovoltaic (PV) at their installation within our electricity distribution network (across north and eastern Victoria). 

 

We are also responsible for maintaining a register for embedded generators with our electricity network. In order to fulfil this obligation, AusNet Services requires that all customers who intend to install PV, battery or an IES to complete and submit the relevant form(s) found below according to the size of their installation.

 

Please note that AusNet Services accepts no responsibility for costs incurred if a customer installs a solar system that exceeds the minimum requirements. Read AusNet Services' minimum system requirements

 

Step 1: Total rating of all PV panels less than (or equal to) 4.6kVA

Step 2: Upgrading your existing solar connection 

Step 3: Total rating of all PV panels exceeds 4.6kVA

Step 4: Application Assessment

Step 5: Engage retailer work request to perform the metering change

Step 6: Electricity retailer work request to perform the metering change

 

Step 1: Total rating of all PV panels less than (or equal to) 4.6kVA

Customers are required to complete the AusNet Services Embedded Generator (EG) Connection Agreement up to 30kVA and return it to AusNet Services via email or mail (refer to contact details below).

 

Please note that systems connected to a Single Wire Earth Return (SWER) network must comply with AusNet Services' minimum system requirements, in particular the limitations for systems connected to a Single Wire Earth Return (SWER) and single phase electricity distribution transformers.

 

On 1 July 2013, AusNet Services (formerly SP AusNet) implemented a new process whereby the Licensed Electrical Installation Worker will conduct anti-island testing, complete the AusNet Services Embedded Generator (EG) Connection Agreement up to 30kVA (including test results) and forward to AusNet Services. This process removes the requirement for a truck appointment for both standard inverters and Micro Inverters. For more information regarding this new procedure please click here. The test will need to be conducted as per AS/NZ 4777 and the Appendix A inverter test procedure.

 

Please return a copy of the Embedded Generator (EG) Connection Agreement up to 30kVA via:

 

Email - send a scanned copy to solar.connections@ausnetservices.com.au

 

Mail - Locked bag 14051, Melbourne City Mail Centre, Victoria 8001 Australia

 

Proceed to Step 5

 

Step 2: Upgrading your existing solar connection

If you have upgraded your existing solar installation and your installation does not exceed 4.6kW, you are required to complete the Alteration or Upgrade of Inverter Energy System Form and return it with a copy of your certificate of electrical safety to AusNet Services.

 

If your installation exceeds 4.6kW, you are required to complete the Embedded Generator Pre-approval form (refer to step 3) to enable the technical review to be conducted.

 

Email - all required forms and single line drawings to preapprovals@ausnetservices.com.au

 

Step 3: Total rating of all PV panels exceeds 4.6kW

Before the solar power installation commences at your premises, a technical review is required to assess the impact of the installation on AusNet Services network when the total rating of the PV panels exceeds 4.6kW.  This is to ensure your solar power installation does not adversely impact the AusNet Services network or other customers.

 

Solar installers are required to provide details of the installation including if you are upgrading your existing solar installation and the total rating of all PV panels will exceed 4.6kW.  The solar installer must complete the Embedded Generator Pre-approval form including a single line diagram and the pre-approval assessment fee (refer to step 4) to enable the review to be conducted.

 

 Samples of single line diagrams:

  1. Single phase installation
  2. Two phase installation
  3. Multiphase installation with 1ph inverters
  4. Three phase installation with 3ph inverters

 

Email - all required forms and single line drawings to preapprovals@ausnetservices.com.au

 

Step 4: Engage your solar installer to commence installation

 

FEES

Maximum net capacity of embedded generating unit

Fees (excl.GST)

Systems less than 4.6kVA - solar connection form agreement Nil
Pre-approval of PV and small generator installation fee (4.6kVA to 15kVA) $145.01
Pre-approval of PV and small generator installation fee (15kVA to 30kVA) $192.24
Project fee* for systems 30kVA - 200kVA $2,000

  * Project fees are additional to the initial pre-approval fee and only payable following the initial pre-approval fee and only payable following the initial pre-approval assessment.           

 

Step 5: Engage your solar installer to commence installation

All inverters must comply with AS4777 (Grid Connection of energy systems via inverters). A list of approved inverters is available on the Clean Energy Council website.

 

Once the solar system has been approved and installed, the solar installer should arrange for the electrical inspector to assess the installation and send a copy of the AusNet Services Embedded Generator (EG) Connection Agreement up to 30kVA to AusNet Services.

 

Step 6: Electricity retailer work request to perform the metering change

To record the solar energy from your system, an interval meter with the capability to record exported energy is required.

 

Customers will need to direct their electricity retailer (the company you receive your bills from) to do the following:

 

  1. Send AusNet Services a copy of the Certificate of Electrical Safety and Electrical Works Request
  2. Send AusNet Services the Service Order

 

Once all documentation is received, AusNet Services will arrange for the PV capable meter to be installed. 

 

If access is required to the meter or switchboard, please advise your retailer for an access appointment to be noted on the service order.

 

Refer to the Single phase AMI re-programmed meter document to learn how to read your solar meter.
