GSD Installations and DRM0 Compliance

We are pleased to see the rising installation rates of Generation Signalling Devices (GSDs) within Queensland. However, recent audit findings have highlighted the recurring issue that Demand Response Mode for Zero Production (DRM0) is not always correctly enabled in inverters during installation. As DRM0 is a core mechanism that allows emergency backstop to function effectively, if it is not correctly enabled, the system operator cannot reliably limit solar exports during network emergencies.

To ensure you have correctly enabled DRM0 on a particular inverter model, we encourage you to contact the inverter’s manufacturer directly for guidance. Manufacturers can provide clear instructions and resources to support compliance.
