For solar installers

You’re installing more distributed energy resources than ever before. As demand for residential rooftop solar, electric vehicles, and small-scale storage increases; the regulatory, policy, and operational frameworks that govern the electricity network need to adapt to the assets connecting to the electricity grid.

By helping to install these new technologies, you’re putting power and control in the hands of consumers.

But networks are still responsible for ensuring that power quality, security and reliability of supply is maintained for everyone. To do this well and to unlock the value of having localised generation assets, the market operator,  AEMO, manages a register of distributed energy resources, known as the DER Register.

Networks are required to collect detailed information on the make and model of all distributed energy resources, which is provided to AEMO to include in this register.

This helps AEMO and the networks make better decisions about how best to invest in and manage the National Electricity Market (NEM) so that we’re working in the best interest of customers.

Can we accept your inverter?

If you are connecting a rooftop solar or a battery system, we require a “smart inverter” that is part of that installation to meet the following criteria:

  1. Be compliant with Australian Standard (AS) / New Zealand Standard (NZS) 4777
  2. Be on the Clean Energy Council (CEC) list of approved inverter types
  3. Be configured so that the power quality response mode complies with the settings in our Model Standing Offer.

Inverters that comply with the AS/NZS 4777.2.2015 standard will only be accepted if they are connected to our network before 18 December 2021. The inverters must be configured with the Volt-Watt and Volt-Var power quality response settings as defined in our current Model Standing Offer.

Currently, we are also accepting inverters that comply with the new AS/NZS 4777.2.2020 standard. The inverters must be configured with the ‘Australia A’ default settings.

From 18 December 2021 onwards, only inverters that meet the new AS/NZS 4777.2.2020 standard will be accepted for connection onto our network. This applies to both new systems and existing systems where an inverter replacement is required. The inverters must be configured with the default ‘Australia A’ settings, which will be specified in our updated Model Standing Offer to be released in December 2021.
