As of 1 July 2017, the Standards Australia has mandated that all PV solar systems 30kVA and greater must install secondary protection relays and comply with the standards outlined in AS/NZS 4777:2015. Responsibility is placed on the owner of the PV solar system to comply with the new protection requirements. Duty of care falls with solar companies and installers to carry out secondary protection injection testing for their customers to ensure their secondary protection relays are functioning to meet their obligations to distributors so they can stay connected.
