Guide for Choosing Top-tier Solar Battery Storage Solutions
Home battery storage systems are becoming increasingly popular, particularly in homes with solar panels. These systems, which allow excess solar energy to be stored for later use, could become commonplace within the next five to 10 years.
One of the most common types of home batteries uses lithium-ion chemistry, such as lithium nickel-manganese-cobalt (NMC). Brands like Tesla and LG Chem use this technology. However, it's important to note that LG storage batteries are currently being recalled due to the risk of overheating and catching fire. If you have a solar storage battery from any of the listed brands, it's advisable to check the product recall details on the ACCC's Product Safety website.
As of July 2025, there are no current recalls reported for LG home solar batteries in Australia. LG solar products in Australia are known for their 25-year warranty coverage on parts and labor, demonstrating confidence in their durability and quality control.
Other types of batteries, such as hybrid ion (salt water) batteries, molten salt batteries, and graphene supercapacitors, are not yet common in use.
When considering whether a battery makes sense for your home, it's essential to factor in the feed-in tariff, home insurance, and the potential impact of a blackout on your system. Government rebate schemes and energy trading systems can also make batteries economically viable for some households.
Lithium batteries, the most common type of home storage batteries, should be more than 90% efficient for every kWh of charge put in. They can give several thousand charge-discharge cycles, can be discharged heavily, are suitable for a wide range of ambient temperatures, and should last for 10+ years in normal use.
Lithium iron phosphate (LiFePO, or LFP) is another common chemistry used in home batteries, said to be safer than NMC due to a lower risk of thermal runaway. It is used in batteries made by BYD and Sonnen, among others.
As of 2024, more than 250,000 home storage batteries have been installed in Australia, with approximately 57,000 installed in 2023 alone. Off-grid systems are usually more complex and expensive than grid-connected systems and are only suitable for remote properties without access to a grid connection.
Joining a Virtual Power Plant (VPP) scheme can improve the economics of a battery installation. A battery captures unused solar power generated during the day for later use at night and on low-sunlight days.
For many homes, the payback time for a battery may be longer than the warranty period of the battery. However, batteries can be worthwhile for homes with high power consumption and for those who value independence from the grid.
Some electricity retailers offer plans that price electricity based on the wholesale market price at 15-minute intervals, which can be profitable if you are prepared to monitor prices and adjust your home energy usage accordingly.
In summary, home battery storage systems are a growing trend for energy-conscious consumers with solar panels. While there are currently recalls for some batteries, LG home solar batteries in Australia have no known recall issues or safety alerts as of July 2025. It's always advisable to check with the manufacturer or official consumer safety authorities for the most up-to-date safety alerts and recall notices.
In the renewable-energy industry, a growing number of households are considering finance options for home battery storage systems, particularly those with solar panels. When making a choice, factors such as feed-in tariff, home insurance, and potential blackout impact should be taken into account.
Despite current recalls for some types of batteries, LG home solar batteries in Australia are known for their 25-year warranty coverage on parts and labor, and as of July 2025, there are no reported recalls. Therefore, these batteries could be a viable and long-lasting option for many homes.
