Choosing a home battery in Australia means navigating a market with a dozen credible options and a lot of marketing noise. This guide cuts through to the practical strengths and weaknesses of the leading brands.
Tesla Powerwall 3
Capacity: 13.5 kWh usable | Warranty: 10 years | Chemistry: NMC lithium-ion
The Powerwall 3 is the most integrated residential battery available — inverter, battery, and EV charging capability in a single unit. Its backup power capability is class-leading, with seamless transition and whole-home backup capacity.
The premium price is the main downside. At $14,000–$18,000 installed, it costs significantly more per kWh than LFP alternatives. The NMC chemistry is also less thermally stable than LFP (though still safe in residential use).
Best for: Households that prioritise backup power, want EV charging integration, and are willing to pay a premium for a polished product.
GoodWe ESA
Capacity: 5–20 kWh (modular) | Warranty: 10 years | Chemistry: LFP
GoodWe has become one of the most popular battery brands in Australia, offering competitive pricing, LFP chemistry, and flexible sizing through a modular stack system. The ESA series pairs with GoodWe's hybrid inverters and is well-supported by Australian installers.
Best for: Cost-conscious buyers who want LFP chemistry, flexible sizing, and a large installer network.
Sungrow SBR
Capacity: 9.6–25.6 kWh (modular) | Warranty: 10 years | Chemistry: LFP
Sungrow is one of the world's largest inverter manufacturers, and the SBR battery benefits from that scale. The modular design allows configurations from 9.6 kWh to 25.6 kWh in 3.2 kWh increments, making it versatile for different household sizes.
The SBR is available in three-phase configuration and pairs with Sungrow's widely-used hybrid inverters, which many Australian homes already have.
Best for: Larger homes, three-phase properties, and existing Sungrow inverter owners.
Enphase IQ Battery 5P
Capacity: 5.0 kWh per unit (stackable) | Warranty: 15 years | Chemistry: LFP
Enphase is unique in using AC coupling and a microinverter-based architecture. Each IQ Battery contains its own microinverter, making the system highly modular and compatible with any existing solar setup. The 15-year warranty is the longest in the market.
The downside is cost — Enphase is among the most expensive per kWh. The modular approach also means that to get 10+ kWh you need multiple units, which adds installation complexity.
Best for: Households wanting maximum modularity, a long warranty, and easy compatibility with non-Enphase solar systems.
BYD Battery-Box HVM
Capacity: 8.3–22.1 kWh (modular) | Warranty: 10 years | Chemistry: LFP
BYD is the world's largest battery manufacturer and brings significant manufacturing scale to the residential market. The Battery-Box HVM uses blade LFP cells — the same technology in BYD's electric vehicles — and is available in flexible configurations.
BYD batteries are inverter-agnostic and work with a wide range of compatible hybrid inverters from SMA, Fronius, SolarEdge, and others.
Best for: Households with an existing hybrid inverter that isn't tied to a proprietary battery, wanting good value LFP chemistry.
How to choose
The "best" battery depends on your home's phase configuration, your existing inverter (if any), your backup power requirements, and your budget.
