Meet Growatt Growatt's APX battery lets you add modules later, even mixed with the ones you have.
- Add modules years from now
Growatt says APX can mix new and older module batches, so topping up later doesn't mean replacing what you have.
Your installer should confirm the inverter and firmware support the extra modules.
- Every module gives its all
Growatt says its modular energy optimisation lets the system fully use every module's energy.
- Five to 30 kWh, your call
One to six 5 kWh modules make a 5 to 30 kWh battery, sized to what you use after dark.
Two APX systems can be linked if you need more.
- APX S2 AU on the list
Growatt lists a 10-year warranty, and the 5 to 30 kWh APX S2 AU models are on the approved list.
Look for an 'AU' model on your quote. Non-AU APX S2 listings end 30 Nov 2026.
Link two APX systems for more capacity.

Is Growatt right for your home? Fit and warranty checks
A good fit if…
- Homes already running a Growatt inverter, where the pairing is straightforward
- Budget-conscious buyers who still want one manufacturer across the system
- Households planning to expand in 5 kWh increments over time
- Off-grid and hybrid builds that need a low-voltage option in the ALP range
Consider the limitations
- You want a storage-first brand with a long dedicated battery record
- You are keeping a different brand’s inverter and want it left alone
- Ecosystem polish and app experience are high on your list
- Your virtual-power-plant program does not support the model
The Growatt range
APX (high voltage)
5–30 kWh, extendable further in multiple columns
The newer high-voltage platform, cobalt-free cells, cable-free module stacking.
ALP (low voltage)
5–40 kWh in 5 kWh units
The 48 V family — off-grid, hybrid and larger stacked builds.
Growatt specifications and source documents
Growatt came to batteries from inverters, and the range reflects it: storage families that pair naturally with Growatt’s own inverters, in both high-voltage and low-voltage forms, sized in roughly 5 kWh steps from small systems up past 40 kWh. Few brands cover that much of the map. The company has been selling into Australia for well over a decade, which puts it in an unusual position — a long local presence in inverters and a much shorter one in home storage.
Growatt questions, answered
- Growatt is known for inverters — is the battery side proven?
- The two reputations are different ages, and it is worth keeping them apart. The inverter business has been in Australia for well over a decade at real volume; the home-storage range is a more recent extension of it. That is not a mark against the batteries, and the shared manufacturing and distribution genuinely help, but it does mean you should judge the storage on storage evidence — installer experience with the exact model, and the support answer for year four.
- What is the difference between the APX, ARK and ALP ranges?
- Voltage class and vintage, mainly. APX and ARK XH are the high-voltage families that suit modern grid-connected hybrid inverters, with APX the newer platform. ALP is the 48 V low-voltage family, the traditional shape for off-grid and certain hybrid builds. Your inverter and your install type determine which is appropriate, so the useful thing is not to pick one yourself but to make the installer explain why they specified the one they did.
- Can I add a Growatt battery to another brand’s inverter?
- Sometimes, but it narrows the options considerably and needs checking against the supported compatibility list rather than assumed. The range is designed around Growatt’s own inverters, and that pairing is where the single-vendor accountability benefit lives. If you are keeping a different brand’s inverter that you are happy with, an AC-coupled battery is usually the cleaner answer than forcing a cross-brand pairing.
- Is Growatt eligible for the federal battery rebate?
- Growatt models do appear on the Clean Energy Council approved battery list, assessed model-by-model. With three families and several variants in play, a brand-level yes is not sufficient — ask to see the exact quoted model on the current list before signing.
- How small can I start, and how big can it get?
- Around 5 kWh is the practical entry point and the range extends past 40 kWh in the low-voltage family, with expansion in roughly 5 kWh units. That granularity is one of the better reasons to consider the brand if your needs are likely to change. The constraint is the headroom designed in at install: the inverter rating and stack configuration set the ceiling, so tell your installer about future plans before the design is locked.
- Does a Growatt system work in a blackout?
- Backup-capable configurations keep the circuits wired to the backup side running, with duration set by the capacity installed and the load drawn. The brand does not change that arithmetic — design does. Ask for the backup circuits to be listed on the quote and for the changeover behaviour to be described, rather than accepting a general statement that the system supports backup.
