Meet SolaX A modular battery that grows 5.1 kWh at a time, up to 66.5 kWh.
- Grow in 5.1 kWh steps
Each module holds 5.1 kWh, and the stackable plug-and-play modules take a system from 10.2 kWh to 66.5 kWh.
Up to three battery towers can link through the TCBox-70, so check it's in your quote if you need more than one.
- Mix new modules with old
SolaX says the optimiser version lets new and older modules work together, so later additions are simpler.
Only the optimiser version does this, so check the model on your quote.
- Fire suppression built in
SolaX pairs LFP cells with aerosol fire suppression, which it says gives precise protection.
- Ten years, 70% at the end
SolaX's Australian warranty runs 10 years, with 70% capacity promised at year ten, within its throughput limits.
Ask your installer to confirm they're SolaX-certified; the warranty requires it.

Is SolaX right for your home? Fit and warranty checks
A good fit if…
- Households planning big storage — or planning to grow into it — where the thirteen-module ceiling means never replacing the system
- Value-focused buyers comfortable with an inverter-maker brand rather than a big-name badge
- Cold-climate homes where the built-in battery heating earns its keep
- Customers of installers who fit SolaX regularly and will support it themselves
Consider the limitations
- You want the big-name brand story and the longest local field history
- You are retrofitting onto a non-SolaX inverter you want to keep
- You want the broadest virtual-power-plant acceptance — verify per model rather than assume
- Your installer has not fitted SolaX before — the range rewards familiarity and punishes guesswork
The SolaX range
LD series (low voltage)
Packs from around 5 kWh, larger parallel options
Suits smaller systems and some retrofit-leaning designs.
SolaX hybrid inverters (required)
Single-phase and three-phase ranges
Triple Power batteries pair with SolaX hybrids — the pairing must be validated model-to-model.
SolaX specifications and source documents
SolaX Power is a high-volume inverter manufacturer whose Triple Power battery line is built around one idea taken further than most: stack depth. Its high-voltage T-BAT systems build from a couple of modules to thirteen in a stack — a span from about 7 kWh to nearly 48 kWh — alongside low-voltage LD packs for smaller or retrofit-leaning jobs, all paired with SolaX’s own single-phase and three-phase hybrid inverters. It is a value-tier choice in the same sense as its inverter-maker peers: the engineering is in the range, not the badge, and the outcome tracks the installer specifying it.
SolaX questions, answered
- Is SolaX a good brand for an Australian home battery?
- It is an established global inverter manufacturer with a real Australian distribution presence and a top-ten customer-rated standing. What it is not is a big-name badge — outcomes with SolaX track the installer more than the brand, which is true of every value-tier system. The real shortlist question is whether your installer fits SolaX often enough to specify and support it well.
- Is a SolaX battery eligible for the federal rebate?
- Model-by-model on the Clean Energy Council approved list, not brand-wide — and with a range spanning two voltage architectures and many stack sizes, the wrong variant is an easy administrative mistake that costs thousands. Make the installer show you the exact quoted model on the current list.
- How big can a SolaX battery actually get?
- Larger than almost any mainstream residential range — the high-voltage stacks build to thirteen modules, nearly 48 kWh in a single stack. Most homes need nothing like that, which is rather the point: a stack specified with headroom today grows by adding modules later instead of replacing the system. Confirm the quoted design actually leaves that headroom.
- What is the difference between SolaX high-voltage and low-voltage batteries?
- The T-BAT high-voltage stacks are the mainstream path — better efficiency, deeper scaling, paired with SolaX’s current hybrids. The LD low-voltage packs suit smaller systems and some retrofit-leaning designs. They pair with different inverters and are not interchangeable, so the architecture choice is made at design time and is expensive to unwind later.
- Can I add a SolaX battery to an inverter I already have?
- Only to a compatible SolaX hybrid — Triple Power batteries pair with SolaX’s own inverters, and even within the family the pairing is validated model-to-model. Retrofitting onto another brand’s inverter means adding or replacing hardware. Ask for the compatibility documentation for the exact two model numbers on your quote rather than accepting a brand-level assurance.
- What happens to a SolaX system in a blackout?
- Backup-capable SolaX configurations switch to the circuits wired for backup automatically; the size of the stack determines how long they run, not how many circuits stay live — that is set by the switchboard design. Make the quote state the backup scope explicitly, because a thirteen-module stack wired to nothing is precisely as useful in an outage as no battery at all.
- Does SolaX handle cold climates well?
- Better than most in its tier — the batteries carry built-in heating for low-temperature operation, which protects winter-morning performance in alpine and highland areas where unheated packs sag. If you are in a genuinely cold spot, it is one of the few spec-sheet lines worth weighting, and worth asking your installer to talk through against the alternatives.
