Top 10 Best Solar Batteries in Australia (2025 Guide)
How Much Do Solar Batteries Cost in Australia? Typical Price Range for 10kWh–15kWh Batteries. Payback Period and Long-Term ROI. What Impacts the Cost of
A decent-sized (10kWh) solar battery starts at about $7,000 before installation. The table above shows the hardware retail price 1 for most home batteries in Australia as of May 2025. The prices include the Federal Battery Rebate. This cuts the cost of installed batteries by around $330 per usable kWh and is available throughout Australia.
The average price for a 10 kWh solar battery ranges between $8,000 - $10,000. While the uptake of solar panels in Australia is really strong, the same cannot be said for solar batteries. A newer technology, battery storage has been viewed as expensive – especially when comparing the payback of a battery system against its expected life.
Lithium-based batteries are the way to go if you're after low maintenance and maximum durability. Models like MANLY's 10kWh LiFePO4 battery or Tesla Powerwall 3 have been built to deliver consistent performance for over a decade, making them a solid investment despite the higher cost of solar battery systems. 3.
The cost varies depending on how many appliances you want to backup. As a guide, solar battery backup can add between $1,500 - $3,500 to the cost of a battery. Not all solar batteries are made from the same materials. Some batteries have Lithium Nickel Manganese (NMC) whereas others are Lithium Iron Phosphate (LiFePO4) or (LFP).
