Off-Grid, Multiple Building Mini-Grid System
Flinders Ranges, SA
Installed: Feb 2013
Off-Grid Energy is a designer and installer of high quality battery storage systems for a range of applications. We are a national company who pride ourselves on friendly and lasting customer service, sustainable business practices, and cutting edge technology.
The requirement for a renewable power solution for this project was primarily to reduce the on-going fuel consumption and maintenance costs of the remote facility. In addition, the promotion of clean and sustainable energy sources was a factor in the choice of the power system investment. At peak occupancy the property accomodates 40 people for a short time, but for most of the year there is only one or two people on site. The power system for this not-for-profit organisation would be funded by a private investment trust.
Property loads included pumps, workshop and office equipment, cooking equipment, fridges/freezers, and lighting. The desert-like conditions dicated a choice of reliable and robust soalr modules, and the pre-assembled
equipment container included passive cooling features.

Apart from the long-term financial and environmental benefits of the renewable mini-grid system, the property is now much quieter with reduced noise pollution removed, and cleaner with less fuel & oils kept on site. The diesel fuel savings from the installation of the system will have a payback of roughly four years.
