Meet SMA SMA, founded in Germany in 1981, makes a battery that plugs straight into its own inverters.
- Made for your SMA inverter
Home Storage plugs into SMA's Sunny Boy or Sunny Tripower Smart Energy hybrid inverter, so one brand runs the whole system.
Needs an SMA Smart Energy inverter. SMA says it is exiting Australia's home solar market; ask your installer about ongoing support.
- Sets itself up on the day
Preassembled cables plug the modules together, and the system sets itself up automatically, leaving less to get wrong on the day.
- Grow in 3.28 kWh steps
Add identical 3.28 kWh modules: up to four on SMA's single-phase inverter, or two to five on its three-phase one.
Extra modules can only be added within 2 years of installation.
- 10-year warranty, registered
Register it in the first 30 days and the warranty runs 10 years, SMA's Australian page says.
Ask your installer to register it before they leave; without registration the factory warranty is 2 years.
IP65 rated, so it can go on an outside wall.

Is SMA right for your home? Fit and warranty checks
A good fit if…
- Households already choosing an SMA hybrid inverter who want the matching battery rather than a third-party pairing
- Three-phase homes, which can use the deeper stack the single-phase inverter cannot reach
- Buyers who value a long-established manufacturer and straightforward, self-commissioning hardware
- People who know their final capacity now and will not need to revisit it after the expansion window closes
Consider the limitations
- You want the largest possible battery, because the range tops out well below what several competitors offer
- You want to keep or choose a non-SMA inverter — Home Storage runs only on SMA’s own hybrids
- You expect to expand capacity years from now, after the two-year window has closed
- You weight the end-of-term capacity floor heavily, since SMA commits to a lower figure than much of the market
- You want a deep body of Australian owner reviews, which barely exists for this product yet
The SMA range
Sunny Boy Smart Energy
Single-phase hybrid inverter
Takes a smaller stack than the three-phase unit because of a voltage ceiling on the string.
Sunny Tripower Smart Energy
Three-phase hybrid inverter
Takes the deeper stack, so three-phase homes reach the top of the range and single-phase homes do not.
SMA specifications and source documents
SMA has been building solar inverters in Germany since the 1980s and the Sunny Boy is one of the most recognised products in the industry. Home Storage is its battery answer, and it is deliberately narrow: one module type, stacked, DC-coupled, running only on SMA’s own Sunny Boy Smart Energy or Sunny Tripower Smart Energy hybrid inverters. It reached the Australian approved-product register in 2025, years after most of its competitors. Buying SMA here is really a decision to buy an SMA inverter system and take the matching battery with it, which is a reasonable thing to want and a poor reason to expect a class-leading battery.
- Current SMA line-up in Australia: SMA Home Storage HS-BM-3.28-10 module (3.28 kWh usable), Two-module stack (6.56 kWh usable), Three-module stack (9.84 kWh usable), Four-module stack (13.12 kWh usable), Five-module stack (16.4 kWh usable). Source
- SMA is DC-coupled: the battery and inverter are one system, so on a retrofit the existing solar inverter is replaced rather than kept. Source
- Usable capacity runs from 3.28 kWh to 16.4 kWh. Source
- Capacity can be added later without replacing the inverter. Source
- The manufacturer warranty is 10 years, with 60% of original capacity guaranteed at the end of it. Source
- It works with SMA's own inverters only. Source
- Listed models are on the Clean Energy Council approved battery list. Source
- The SMA Home Storage module is on the Clean Energy Council approved battery list, but one module on its own falls below the federal Cheaper Home Batteries Program, which covers systems from 5 kWh to 100 kWh of usable capacity: a qualifying SMA system therefore starts at two modules. The program pays its full rate on the first 14 kWh of usable capacity and tapers above that, a boundary the deeper three-phase stack crosses and the single-phase stack does not. Source
SMA questions, answered
- Is SMA a good battery brand, or just a good inverter brand?
- Those are genuinely different questions. SMA has decades of respected inverter engineering behind it, and its battery is newer, narrower and later to market than most competitors — SolarQuotes calls the company a laggard on home batteries and describes the specification as underwhelming against current options. If you want an SMA system, the battery is a sensible companion. If you are shopping for the best battery on its own merits, look wider.
- Is SMA eligible for the federal battery rebate?
- The SMA Home Storage module is on the Clean Energy Council approved battery list, which is the hardware gate for the Cheaper Home Batteries Program, and a stack of two or more modules sits comfortably inside the program’s usable-capacity band. The install still has to qualify on the usual conditions: solar connected, an accredited installer, and no earlier claim at the address.
- Can I add more capacity to an SMA battery later?
- Only for a limited time. SMA states that additional modules can be integrated into an existing system within two years of the initial installation. After that the stack you have is the stack you keep. It also says separate storage systems cannot be connected in parallel, so there is no way to add a second stack alongside the first. Decide your ceiling before you install, not after.
- Why does registration matter so much on this brand?
- SMA’s Australian page describes a short factory warranty that is extended by a further eight years only if the owner registers the product in its online service centre within thirty days of commissioning. That is most of the warranty you thought you were buying, contingent on a step that takes minutes. Ask the installer to do it before they leave and to send you the confirmation.
- Can I use an SMA battery with the inverter I already have?
- No. SMA states Home Storage is compatible with its own hybrid inverters, the Sunny Boy Smart Energy and the Sunny Tripower Smart Energy, and nothing else. On a new solar-and-battery install that is simply the system you are buying. On a retrofit it means the existing inverter is replaced, which should appear on the quote as a clear line rather than folded into a single total.
- Does single-phase or three-phase change what I can buy?
- Yes, and more than on most brands. The single-phase Sunny Boy Smart Energy accepts a shallower stack than the three-phase Sunny Tripower Smart Energy because of a voltage limit on the battery string. So a single-phase house cannot reach the top of the published range at all. If your capacity target is near the upper end, establish which inverter you are getting before anything else.
- Will an SMA system run my house in a blackout?
- The battery has an integrated black-start function for backup supply when paired with an SMA hybrid inverter, and full-home backup uses an additional external box rather than coming built in. Which circuits stay live and whether that extra hardware is included are both quote-stage decisions, so ask for the backed-up circuits by name and check the backup box is itemised.
