A 19 kW / 61.4 kWh remote area power system (RAPS) has been installed almost 1,000 kilometres northwest of Adelaide in the remote Great Victoria Desert region, to carry the bulk of the Traditional Owner community’s energy needs.
Mt. Willoughby Station Traditional Owner representatives, the Tjirilya Aboriginal Corporation (TAC) has been relying on an ageing off-grid power system that depended heavily on a diesel generator to meet daily power needs, experiencing rising fuel use and ongoing reliability concerns.
Located 251 kilometres south of the Northern Territory (NT) border, the system is single-phase built around a Victron MultiPlus-II inverter/charger, delivering 15 kVA of power to support daily operations while allowing for future expansion as requirements grow.
Adelaide-based energy company and system designer and installer MyEnergy Engineering said it includes 40 roof-mounted JA Solar panels, installed using a Schletter mounting system and supported by 61.44 kWh of ZYC Energy battery storage to ensure reliable power availability.
The system was integrated into the existing infrastructure, including the existing generator, which now operates as backup only when required.
Key components include an SMA Sunny Boy 5 kW inverter, Victron SmartSolar MPPT RS 450/100-Tr, Victron SmartSolar MPPT RS 450/200-MC4 and Victron Ekrano GX.
The system was remotely designed, pre-built and fully tested at MyEnergy headquarters, housed within a large weather and vermin-resistant custom steel cabinet. This approach allowed for efficient transport to site and reduced installation time in the remote location.
TAC is responsible for land management across the region to conserve their munda (Country) for ecological, environmental and cultural heritage preservation, and the new system provides a dependable power supply to support day-to-day living and conservation operations.
Reliance on the generator has been significantly reduced, keeping it as a backup as needed.
