The best batteries in Australia

By My Energy Mate Editorial · Last updated

Quick Answer

The best battery for most Australian households in 2026 is the Sigenergy SigenStor (scored 8.8/10), with the Tesla Powerwall close behind. For pure value the GoodWe Lynx Home F G2 12.8 kWh leads at about A$820 per kWh. Rankings weigh specs, installed pricing and verified installer feedback.

  1. 1. Sigenergy SigenStor

    8.8/10

    Sigenergy's SigenStor is a modular, stackable battery-inverter system (8 to 48 kWh) that has become Australia's best-selling battery in 2026. Installed prices start around A$9,000 for 8 kWh. It wins on flexibility, an excellent app and integrated EV-charger options, though the brand is young and its long-term support record is unproven.

  2. 2. Tesla Powerwall

    8.6/10

    The Tesla Powerwall 3 is a 13.5 kWh integrated battery-and-inverter system costing roughly A$12,500 to A$15,500 installed in Australia as of August 2026. It suits households wanting whole-home backup and a polished app, but its fixed size and premium price mean modular rivals often deliver cheaper storage per kWh.

  3. 3. Sungrow SBH/SBR

    8.4/10

    Sungrow's SBR and newer SBH batteries are modular LFP systems (9.6 to 40 kWh) from one of the world's largest inverter makers. At roughly A$900 to A$1,100 installed per usable kWh they balance price, proven reliability and wide installer familiarity, making them the default safe choice for many Australian homes.

  4. 4. BYD Battery-Box

    8.2/10

    BYD's Battery-Box Premium HVS/HVM towers are modular LFP batteries (5.1 to 22.1 kWh per tower) from the world's biggest EV maker. Proven over a decade in Australia and compatible with many third-party hybrid inverters (notably Fronius), they cost roughly A$900 to A$1,000 per usable kWh installed.

  5. 5. GoodWe Lynx

    7.9/10

    GoodWe's Lynx Home series are modular LFP batteries (6.6 to 28.8 kWh) that pair with GoodWe hybrid inverters at some of the lowest installed prices in the Australian market, from about A$7,500 for 6.6 kWh. A solid budget-to-midrange pick, with fewer premium features than Sigenergy or Tesla.

  6. 6. Alpha ESS

    7.7/10

    Alpha ESS builds all-in-one and modular storage systems (SMILE range, 2.9 to 30+ kWh) with an Australian office since 2016 and a large installed base. Pricing sits in the value tier at roughly A$850 to A$1,000 per usable kWh installed. A dependable mid-market choice, though efficiency and app polish trail the leaders.

  7. 7. Fox ESS EP/ECS

    7.2/10

    Fox ESS sells aggressively priced modular LFP batteries (EP and ECS ranges, 5.2 to 40+ kWh) that undercut most rivals at roughly A$750 to A$900 per usable kWh installed. The hardware is capable, but surge output limits, a young brand history and patchy support reports make it a price-first rather than peace-of-mind choice.

Methodology: expert score weighs hardware capability (40%), value per unit (30%), warranty and support record (20%) and software (10%). No brand pays for placement.
