Our top picks for 2026
Tesla Powerwall 3
The all-in-one default: 13.5 kWh, an integrated inverter, whole-home blackout backup, and the best app + VPP experience. You pay more per kWh, but it's the simplest single-product solution.
GoodWe Lynx Home F
The lowest cost per usable kWh of any tier-1 battery, especially paired with a GoodWe hybrid inverter. Modular from 5.4 kWh, so you only buy what you need.
BYD Battery-Box Premium HVS
Stackable in 2.56 kWh modules from 5.1 up to 22.1 kWh. Start with what fits the budget, add capacity when you get an EV or go all-electric.
Sigenergy SigenStor
Integrated inverter + battery that stacks to 48 kWh with whole-home backup, ideal for large or all-electric homes that want one tidy unit instead of separate boxes.
sonnenBatterie Evo
German-built with a 10,000-cycle warranty (the highest in market) and the sonnenFlat capped-rate VPP plan. The pick if you want maximum lifespan.

How to choose a home battery
- Size it to your evening use, most homes import 5–12 kWh between 4pm and midnight. A 10–13.5 kWh battery covers the typical family; oversizing just lengthens payback.
- All-in-one vs modular, if you don't have a battery-ready inverter, an all-in-one (Powerwall 3, Sigenergy) avoids buying a separate hybrid inverter. If you do, a modular battery is cheaper.
- Backup matters to you?, confirm whether it's whole-home or essential-circuits-only, and whether a gateway is included.
- Check the rebate stack, the federal rebate applies everywhere; NSW and WA stack a state rebate; a VPP adds ongoing credits.
Common questions
What is the best home battery in Australia?
For most households the Tesla Powerwall 3 is the best all-round home battery, 13.5 kWh, an integrated inverter, whole-home backup and excellent VPP support in one unit. The best choice for you depends on budget, whether you want to expand later, and whether you already have a compatible inverter.
What is the best value home battery?
The GoodWe Lynx Home F and Growatt APX offer the lowest cost per usable kWh among tier-1 batteries (around $700–$900/kWh installed before rebate). Paired with a matching hybrid inverter and the federal rebate, they deliver the cheapest usable storage.
Which home battery has the best blackout backup?
All-in-one units with whole-home backup, the Tesla Powerwall 3 and Sigenergy SigenStor, give the most reliable blackout protection. Modular batteries (BYD, Sungrow, GoodWe, sonnen) can do backup too, but usually need an add-on gateway and may cover only essential circuits.
How much does the best home battery cost?
Premium all-in-one batteries like the Tesla Powerwall 3 run about $12,500–$14,500 installed before rebates (around $9,869 after the federal rebate). Value-tier batteries start nearer $7,000–$9,000. See our full solar battery price guide for the breakdown.
