Why Off-Grid?


In South Australia, going off the grid with solar has many benefits. One of the largest advantages is reduced energy costs, as rural households are generally charged excessive grid connection fees by utility companies.


If your building is unable to connect to the local power grid, an off-grid solution may be your best alternative. If you wish to obtain energy independence, it is also possible to withdraw from the power grid.


Off-grid solar energy systems are great for remote worksites, homes, businesses, and other rural operations, specifically for those who use diesel fuel for power generation.


There are many additional reasons to install an off-grid system, including:

  • Protection from power outages
  • Reduction in diesel generation usage and costs
  • No expensive grid connection charges
  • Scalable up to 76 kW (IEC) or 61kW (UL)
