Choosing a home solar battery in Australia can feel overwhelming. Compare trusted brands and find the right system for your home with VoltX Energy.
With rising electricity costs and more frequent outages in Australia, it’s no surprise many people are going solar. The problem is, switching to solar can be quite tricky. Whether you’re new to solar or upgrading your existing system, choosing the right battery to pair with it can be overwhelming.
Many homes face the same problem—too much information and every brand claiming to offer the best home battery in Australia. If you’re one of them, know that the smartest way to choose a home battery system is to match your budget, usage, and setup.
VoltX Energy makes this easier with a curated range of trusted brands like VoltX Energy Whale, Hinen, Pylontech, AlphaESS, and OliPower. Finding a good solar battery has never been simpler.
Why Every Aussie Home Needs a Smart Home Battery System
Home batteries have shifted from a nice-to-have to a mainstream investment. Three trends explain why more Australians are choosing to store their power.
Batteries Have Gone Mainstream
Australians installed around 221,000 home battery systems in 2025—roughly triple the year before—according to analytics from SunWiz. About 4.6% of homes now have one, and average system sizes have almost doubled as households size up for whole-home backup.
Grid Power Is Still Expensive
Electricity remains a major household cost. After steep rises in 2025, typical annual bills sit around $2,000 or more in many networks, according to Australian Energy Regulator figures, and households on default plans can overpay hundreds of dollars a year compared with the cheapest available offer.
Stored Solar Is Worth More Than Exported Solar
Feed-in tariffs have fallen to just a few cents per kWh, while grid power in the evening peak can cost 30–45 cents. Using your own stored solar at night beats selling and buying it back later. See the state-by-state detail on solar export tariffs in Australia.
Not sure what to look for? Capacity, chemistry, efficiency, warranty, and price all matter, and we work through each in our home solar battery guide.

Frequently Asked Questions
Think about three things: how much power you use each day, which appliances you'd want running in an outage, and where your budget sits. From there, look for a battery with enough capacity to cover your essentials, and ideally one you can expand later as your energy needs grow.
It depends on the battery’s size and how much energy your home uses. Most systems can power basic appliances for several hours, while larger setups can last overnight or even longer.
Size it to your evening and overnight load rather than your whole day, since solar covers most daytime use directly, then add a buffer of around 20 to 30%. Our battery sizing guide walks through the full calculation.
Yes, VoltX Energy batteries are designed to work with most solar systems and inverters. Our team can also help make sure everything connects smoothly and safely.
It mostly comes down to your power setup and how much you want to store. Smaller, single-phase homes are well suited to single-phase options like Pylontech or AlphaESS. Larger, three-phase households are better suited to higher capacity three-phase systems.
