Sofar Inverter DRM0 Commissioning Guideline for TMAC GSD
Introduction
What is the GSD?
From 6 February 2023, all new and some replacement inverter energy systems (like rooftop solar
PV) in Queensland, with an aggregated capacity of 10kVA and above, will require a generation
signalling device (GSD), to enable the inverter to receive a signal to switch off via DRM0. The
signal is sent to the GSD from Ergon Energy Network and Energex's powerline signalling system,
known as Audio Frequency Load Control (AFLC). For larger sites with multiple inverters, including
embedded networks, installers have the option of using a GSD on each inverter or installing a
single GSD connected to a Demand Response Controller. Some exclusions apply to the
requirement to install a GSD – including inverter energy systems where the inverter is solely
supplied by a battery, and any inverter energy systems installed at a location that is not serviced by
the AFLC system.
