Chasing a single best battery is the wrong question. A great battery for a small townhouse is overkill for one home and undersized for another. The smarter move is to match a few key features to how your household actually uses power, then pick a reputable brand within budget.
The features that actually matter
- Usable capacity (kWh). How much you can actually store and use. Most homes suit 10kWh to 13.5kWh.
- Backup capability. Whether it keeps your home running through a blackout. Worth it if outages are common in your area.
- Warranty. Look for a 10-year warranty and a stated end-of-warranty capacity (how much it will still hold).
- Round-trip efficiency. How much of the stored energy you get back. Higher is better, and the leading brands are all strong here.
- VPP readiness. If you want to earn from a Virtual Power Plant, check the battery is compatible with programs in your state.
- Inverter fit. A hybrid or AC-coupled setup depending on your existing solar. Your installer confirms this.
Brands Australians install most
A handful of brands dominate Australian installs, all with solid track records. The right one comes down to availability, price and what your installer recommends for your setup.
- Tesla Powerwall 3. 13.5kWh with a built-in inverter and whole-home backup option.
- Sungrow. Flexible, well-priced modular storage that scales with your needs.
- GoodWe. Stackable Lynx storage paired with well-regarded hybrid inverters.
- BYD. Battery-Box stackable modules with strong value for money.
- Enphase IQ. Modular microinverter-based system, easy to expand over time.
- AlphaESS. Tidy all-in-one systems that are VPP-friendly.

We stay brand-neutral. Your matched installer recommends what genuinely suits your roof, usage and budget, not whatever they have the biggest margin on.
Match the battery to the rebates
Whichever brand you choose, the federal Cheaper Home Batteries discount applies to eligible models, and your state incentive stacks on top. The after-rebate price is what really matters, and it is what a free rebate check returns.
