Information 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 facilitating the adoption of these new technologies you are 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 all consumers. To do this well and to unlock the value of having localised generation assets, the market operator, AEMO, will start managing a register of distributed energy resources, known as the DER Register.

Effective 1 December 2019, networks will be collecting detailed information on the make and model of any distributed energy resources as part of this register. We will pass this information on to the market operator. This will help AEMO and the networks make better decisions about how best to invest in and manage the National Electricity Market (NEM) so that we are working in the best interest of customers.

Also from 1 December 2019, all Victorian Network Service Providers are mandating the use of “smart inverters” that have power quality response mode settings (i.e. ‘Volt-Watt’ and ‘Volt-Var’ applied), for new solar installations. With the increase in localised, rooftop solar installations, smart inverters will ensure that customers experience less trip offs as a result of power quality fluctuations. This change will also support the increase in uptake of solar by helping to maximise the amount of solar by feeder.
