Grid Connected Home Batteries in South Australia, Australia

South Australia is a national leader in renewable energy, and home battery adoption is growing rapidly. The state now has 39,585 battery systems installed, providing a combined 234,832 kW of power capacity and 505,539 kWh of storage capacity. This means around 4.9% of dwellings in South Australia are equipped with batteries, the highest uptake in the country. The average home battery in South Australia delivers 5.93 kW of power and 12.77 kWh of storage, giving households the ability to capture excess solar energy and use it at night or during peak demand. This boosts energy independence, reduces reliance on grid electricity, and provides reliable backup power during outages.

Battery storage complements South Australia's world-leading solar adoption. With 52.6% of dwellings already fitted with rooftop solar systems — equating to more than 420,722 installations and 2,587 MW of solar capacity — adding batteries allows households to maximise the value of their renewable energy. From Adelaide's suburban homes to regional centres like Mount Gambier, Port Lincoln, and Whyalla, battery technology is transforming how South Australians manage their energy. Government support programs, along with falling installation costs, have helped accelerate adoption and made batteries more accessible to everyday households. As South Australia continues to push the boundaries of renewable energy integration, home batteries are playing a crucial role in building a more sustainable, resilient, and self-sufficient energy future.
