Solar batteries and prices in Australia

Updated January 2025

If you’re thinking of buying a solar battery for your home, our helpful article on real solar batteries and prices in Australia in 2025, you might be wondering how much it will cost and what size you need. In this educational blog post, we’ll give you some guidance on how to compare solar battery prices and sizes in Australia based on battery capacity, brand, and the state in which you live.

Solar battery prices vary depending on the storage capacity, which is measured in kilowatt-hours (kWh). The more kWh a battery can store, the more electricity it can provide for your home when the sun is not shining. The average solar battery price in Australia is approximately $700-900per kWh of storage, excluding installation costs. We think that is still much too expensive, our batteries are usually around 20-50% lower in price, yet better quality in most cases.

The price of a solar battery in Australia usually ranges from $3,500 to $15,000 or more, depending on the specifications. Below is a general breakdown based on capacity:

Prices include the battery unit but usually not installation. Installation can cost an additional $1,000 to $3,000, depending on the complexity.

Tesla’s Powerwall 2 and 3 costs around $13,500 for a 13.5 kWh battery ($1000 AUD per kwh), while SunGrow’s SBR096 costs around $8499 for a 9.6 kWh battery (about $900AUD per kwh).

However, the solar battery price also depends on the brand and model of the battery. Some brands, such as Tesla, LG Chem, and Sonnen, are more expensive than others, such as SunGrow and Growatt. Several factors are at play in this pretty new market.

1. Brand
2. Intelligence of Software
3. Quality of components
4. Inbuilt inverter (tesla)
5. Warranty period
6. Who you buy your solar system from

You should compare different brands and models to find the one that suits your needs and budget.

Some of our batteries offer a cost of approximately $384 AUD per kwh. Such as the our Lifepro 15.5kwh off grid battery which starts at $5999!

Paired with a High Quality CEC Inverter our battery can give you high end features, at a fraction of the cost.

Why? We are a small business with far lower operating costs. We dont need to support expensive sales people, or large numbers of accounting staff.

Why are brand name batteries so expensive?

Its a walled garden, a well established channel of sales funneled through existing distributors and supplers. this allows most solar companies, to sell you what they profit most from, and nothing else. It’s very anti-competitive and very much about profit margins for the owners and salespeople of these companies.

Another factor that affects the solar battery price is the state where you live. Some states, such as South Australia and Victoria, did offer rebates and incentives for installing solar batteries, which could reduce the upfront cost significantly. Other states, such as Queensland and New South Wales, have higher electricity prices, which can increase the savings from using a solar battery. You should check the eligibility criteria and availability of rebates and incentives in your state before buying a solar battery.

Performance: The performance (lifespan) of a solar battery depends on its efficiency, depth of discharge (DoD), cycle life, and backup capability. Efficiency is how much energy the battery can deliver compared to how much energy it receives from the solar panels. The higher the efficiency, the less energy is wasted during charging and discharging. LiFePO4 excels with efficiency. Especially compared to Lead based batteries. Anyone spruking Lead based batteries, really has very little knowledge of total cost of ownership and performance, and therefor should be immediately ignored.

Depth of discharge is how much of the battery’s capacity can be used before it needs to be recharged. The higher the DoD, the more energy you can use from the battery. Cycle life is how many times the battery can be fully charged and discharged before its capacity drops below a certain level. The longer the cycle life, the longer the battery will last. Backup capability is whether the battery can provide power to your home during a blackout or when the grid is down. Not all batteries have this feature, so you should check if this is important to you.

To sum up, solar battery prices and sizes in Australia depend on several factors, such as storage capacity, brand, model, and state. You should do your research and compare different options to find the best solar battery for your home.
