1. Tesla Powerwall 3
~$16,100 installed | ~$11,650 post-rebate | 13.5 kWh | 11.5 kW continuous | IP67 | 10-year warranty
The Tesla Powerwall 3 is genuinely good value once you factor in what you’re getting. Unlike every other battery on this list, the Powerwall 3 includes a full solar inverter. For a new solar installation, you’re not paying $16,100 for a battery alone. You’re replacing the battery plus a separate inverter that would otherwise cost $2,500 to $4,000 on its own.
The headline spec is the 11.5 kW continuous power output. No other residential battery in Australia comes close. During a blackout, you can run ducted air conditioning, an induction cooktop, the fridge, lights, and still have headroom. That kind of backup capability matters in areas prone to storm outages.
The 89% round-trip efficiency is the lowest among the top-tier options here, and that does cost you something over time. Every 100 kWh you cycle through the Powerwall recovers 89 kWh; the Sungrow and BYD return 97 kWh and 96 kWh respectively. Over a year of daily cycling, the difference is roughly 100 to 150 kWh of lost energy.
Wait times have also been a legitimate issue, with some customers reporting 3 to 6 month lead times in late 2025. If you need a battery quickly, that’s worth confirming with your installer.
IP67 weatherproofing is the best in this class and makes the Powerwall 3 genuinely suitable for exposed outdoor walls, coastal locations, or flood-prone properties.
Best for: New solar builds, large households wanting maximum backup output, coastal or flood-risk installations.
2. Sungrow SBR HV
~$12,500 installed | ~$8,270 post-rebate | 12.8 kWh | 9.6 kW continuous | IP55 | 10-year warranty
The Sungrow SBR HV leads the market on efficiency at 97% round-trip. That means less of your solar energy is wasted in the charge-discharge process than with any other battery here. For households primarily motivated by energy savings, that efficiency advantage compounds meaningfully over a decade of daily use.
Sungrow is the world’s largest solar inverter manufacturer, and its Australian installer network is one of the deepest in the country. The SBR range is modular in 3.2 kWh increments, which means you can start at 9.6 kWh and expand without replacing the whole system.
The catch is real and you need to understand it before quoting: the Sungrow SBR only works with a Sungrow SH hybrid inverter. If your home runs a Fronius, SMA, SolarEdge, or any other brand, this battery is not compatible without swapping your inverter. For new builds going Sungrow from the start, that is no constraint at all. For retrofit customers, it often is.
At $8,270 post-rebate for 12.8 kWh, the Sungrow sits in an attractive price bracket for a quality system.
Best for: New Sungrow inverter installations, efficiency-focused buyers, households wanting expandable modular storage.
3. BYD Battery-Box HVM
~$13,600 installed | ~$9,046 post-rebate | 13.8 kWh | 8 kW continuous | IP55 | 10-year warranty
The BYD Battery-Box HVM is Australia’s most popular home battery, and the reason is simple: it works with almost everything. Fronius, SMA, SolarEdge, GoodWe, and Sungrow all pair with the BYD HVM. That inverter-agnostic approach makes it the default recommendation for homes retrofitting storage onto an existing system.
BYD manufactures battery cells for some of the world’s best-selling electric vehicles. The cobalt-free LFP chemistry is proven at scale in demanding conditions. At 96% round-trip efficiency, it’s only a fraction behind the Sungrow.
The 8 kW continuous power output is lower than the Powerwall 3 and Sungrow SBR, which means higher load scenarios during a blackout require a bit more management. For most households, 8 kW is still plenty. The 13.8 kWh capacity is generous, and the system scales to an extraordinary 66 kWh for large properties or commercial crossover use cases.
Best for: Retrofit onto any compatible inverter, 3 to 4 person households, large properties planning future expansion.
4. GoodWe Lynx Home F G2
~$11,100 installed | ~$6,876 post-rebate | 12.8 kWh | LFP | 10-year warranty
At roughly $6,876 post-federal rebate, the GoodWe Lynx Home F G2 offers the lowest entry price of any 12-plus kWh battery from a credible manufacturer in this comparison. GoodWe is a top-5 global inverter manufacturer with CEC approval and a growing Australian installer footprint.
The Lynx F G2 uses LFP chemistry and a 10-year warranty, which keeps it on par with the Sungrow and BYD on longevity. Detailed power output and efficiency specs vary by configuration, so confirm the exact figures for your planned system with your installer.
For households where budget is the primary constraint and a large-capacity, reliable battery is the goal, the GoodWe Lynx is a serious option. The price advantage over the BYD and Sungrow is significant.
Best for: Budget-conscious buyers wanting 12-plus kWh, GoodWe inverter owners, value-first purchasers.
5. Alpha ESS SMILE5
~$12,372 installed | ~$7,983 post-rebate | 13.3 kWh | 5 kW | LFP | Split warranty
The Alpha ESS SMILE5 sits at a competitive installed price and uses LFP chemistry with a 13.3 kWh usable capacity. At 5 kW continuous, it’s on the lower end for power output, which limits its usefulness for whole-home backup during outages.
The warranty structure is worth understanding before you commit. The inverter carries a 5-year warranty while the battery module itself is covered for 10 years. That split is less reassuring than a unified 10-year whole-system warranty. Inverter failures in years 6 to 10 are not unheard of, and you’d be covering replacement costs yourself.
Alpha ESS has a solid presence in Australia and a decent installer network. For households who want a mid-range price point and are not concerned about backup output or the warranty gap, the SMILE5 is worth considering.
Best for: Mid-range buyers comfortable with the split warranty, moderate evening energy use, non-backup-critical applications.
6. Enphase IQ Battery 5P
~$14,600 installed | ~$11,270 post-rebate | ~10 kWh (2 units) | 15-year warranty | LFP | AC-coupled
The Enphase IQ Battery 5P carries the longest warranty in Australian residential storage at 15 years. Each unit stores 4.96 kWh, so most households need two units for practical overnight coverage. That brings the installed price to around $14,600 for roughly 10 kWh, which is the highest per-kWh cost among all batteries here.
The 15-year warranty is genuinely valuable if you plan to stay in the property long term. No other battery in this roundup comes close on warranty length. The AC-coupling design means it works with any solar system, including existing microinverter setups.
The Enphase is the obvious choice for anyone already running an Enphase IQ8 microinverter system. Outside that ecosystem, the cost-per-kWh makes it harder to justify against the BYD, Sungrow, or GoodWe alternatives.
Best for: Enphase IQ8 microinverter owners, buyers prioritising long-term warranty certainty, incremental storage builds.
How to Choose
The single most important question before picking a battery is whether you have an existing solar inverter or are starting fresh.
For new solar builds, the Tesla Powerwall 3’s integrated inverter makes it a genuinely competitive all-in-one system. The Sungrow SBR HV is the alternative if you want maximum efficiency and are going Sungrow throughout.
For retrofits onto an existing inverter, the BYD Battery-Box HVM is the most reliable choice by inverter compatibility alone. The GoodWe Lynx is worth looking at if budget matters most.
For those wanting the longest warranty on the market, Enphase’s 15-year coverage is unmatched. Just go in knowing the per-kWh cost is higher.

How long do home batteries last in Australia?
Most LFP home batteries carry a 10-year warranty and are designed for 4,000 to 6,000 full charge cycles. Daily cycling over 10 years in Australian conditions is well within these limits. Enphase goes further with a 15-year warranty. Real-world degradation for quality LFP systems is typically less than 20% over the warranty period.
Can a home battery power my house during a blackout?
Yes, if the battery is set up for backup. The Tesla Powerwall 3 handles the most simultaneous load at 11.5 kW continuous, enough for air conditioning, cooking, and EV charging at once. The Sungrow SBR (9.6 kW) and BYD HVM (8 kW) can also back up a typical home, though you may need to manage high-draw appliances.
What size home battery do I need?
A household using 20 to 30 kWh per day typically stores 10 to 15 kWh in a battery and covers most overnight needs. If you want to reduce grid dependency significantly or support an EV, 13 to 16 kWh is a solid target. Homes with large evening usage or those in areas with frequent outages may benefit from 16 kWh or more.
