Meet iStore One Australian brand for your battery, inverter, hot water and EV charger.
- Grow from 5 to 60 kWh
Start at 5 kWh and add compatible modules as your needs change, up to 60 kWh, without replacing the battery.
Each stack takes up to three 5 kWh modules, so bigger systems use more than one stack.
- Quiet, with no cooling fan
Natural cooling with no fan keeps noise under 29 dB, so it hums along quietly in the background.
- Installers' third pick
In SolarQuotes' 2026 survey, 11% of installers chose iStore for their own home, ranking it third.

Is iStore right for your home? Fit and warranty checks
A good fit if…
- Households electrifying broadly — storage, hot water, EV — who want one brand and one support chain across the lot
- Buyers who specifically want an Australian brand with local distribution behind the badge
- Value-focused homes where modular sizing from small to very large matters
- Customers of installers who carry iStore’s range and support it directly
Consider the limitations
- You want the deepest possible national installer network wherever you live
- You are retrofitting onto an existing non-iStore inverter you want to keep
- Virtual-power-plant participation is central to your plan — verify program acceptance per model before counting on it
- You want a global-scale manufacturer’s volume behind the hardware rather than a local brand’s curation of it

iStore specifications and source documents
iStore is an Australian energy brand whose pitch is the electric home as a whole rather than the battery alone: a modular home battery scaling from 5 to 60 kWh, its own hybrid inverters, heat pump hot water systems, EV chargers and pool heating, sold and supported through an established local distribution network. The battery itself is conventional modular LFP engineering; the differentiation is the ecosystem and the local accountability of an Australian brand. As a smaller local player, its footprint is deepest in Western Australia and thinner east — installer familiarity varies more by region than with the national brands.
iStore questions, answered
- Who is iStore — is it really an Australian brand?
- iStore is an Australian energy brand selling batteries, hybrid inverters, heat pump hot water, EV chargers and pool heating through local distribution. Like most local brands it curates and engineers its range rather than fabricating every cell itself — what you are buying is the Australian accountability layer: local distribution, local support, one brand across the electric home. Ask who handles support in your region, because depth varies by state.
- Is an iStore battery eligible for the federal rebate?
- Model-by-model on the Clean Energy Council approved list, as with every brand. With a modular range the specific configuration matters, so have the installer show you the exact quoted model on the current list before you sign anything.
- How big can an iStore battery system get?
- The modular range runs from 5 kWh to 60 kWh, which covers everything from a small starter battery to genuinely large storage for big or off-peak-hungry households. The usual modular caveat applies: the ceiling that matters is the one your quoted configuration was designed for, so confirm what adding modules later actually involves.
- Is bundling hot water and EV charging with the battery a good idea?
- The engineering logic is sound — a heat pump running on midday solar shifts a big recurring load onto power you have already paid for, and one brand across the pieces simplifies support. The commercial logic needs checking piece by piece: each component should stand on its own merits and price, not ride the bundle. A good installer will happily quote the pieces separately so you can see.
- Can I add an iStore battery to solar I already own?
- iStore batteries pair with iStore’s own hybrid inverters, so the natural path is the system taking over the inverter role rather than bolting onto another brand’s hardware. On ageing solar that can be a sensible generational refresh; on a recent inverter it means replacing something that works. Ask the installer to justify the design against an AC-coupled alternative that would leave your inverter alone.
- What happens to an iStore system in a blackout?
- Backup-capable configurations hold up the circuits wired to the backup side automatically, and the modular capacity determines how long they run. As with any hybrid system the scope is set at design time — which circuits, which phase, what happens as the modules run down — so have the quote spell out the blackout behaviour rather than accepting a general assurance that the battery has backup.
- Is a smaller Australian brand riskier than a global one?
- It is a different risk, not automatically a bigger one. Global scale means volume-tested hardware but support that can end at an importer; a local brand means the accountability sits here but on a smaller organisation. The practical questions are the same either way: how long has the support chain existed, who answers in year four, and how experienced is the installer with this exact product. Weight those over the size of the logo.
