Meet AlphaESS All-in-one SMILE systems for new solar, or for the solar you already have.

  • New solar or existing solar

    Choose the SMILE-G3-S5 hybrid for a new solar system, or the B5 to add storage beside existing solar.

    Ask which version your quote is: S5 (hybrid) or B5 (AC-coupled).

  • 9.3 kWh modules, all usable

    Each module holds 9.3 kWh at 100% depth of discharge, and up to four link together for 37.2 kWh.

  • More panels on one inverter

    The S5 takes up to 10 kW of panels on a 5 kW inverter, so more of your roof can feed the battery.

    Your local network's rules can limit how much solar you connect.

Is AlphaESS right for your home? Fit and warranty checks

A good fit if…

  • Households whose size or phase setup does not fit the one-model brands neatly
  • Three-phase properties wanting serious storage capacity without top-tier positioning
  • Buyers who value a storage-only specialist over a brand extending from another product line
  • Customers of installers who fit AlphaESS regularly and support it themselves

Consider the limitations

  • You want a household-name brand your neighbours already recognise
  • You want the deepest possible Australian consumer support footprint behind the badge
  • Your installer is proposing AlphaESS for the first time — specialist ranges reward familiarity
  • You are retrofitting onto an existing inverter you want to keep, since SMILE systems are integrated by design

The AlphaESS range

SMILE-M5 (single-phase)

Steps from 5 to 20 kWh

The compact path for typical single-phase homes.

SMILE-G3 (single-phase)

Builds from under 4 kWh to over 37 kWh

The current-generation family with the widest single-phase span.

SMILE-G3 three-phase

Multiple inverter sizes, storage beyond 60 kWh at the top

Covers three-phase homes from modest to genuinely large systems.

AlphaESS specifications and source documents

AlphaESS does one thing — energy storage — and its SMILE range shows it: integrated battery-and-hybrid-inverter systems spanning compact single-phase homes up to large three-phase properties, with capacities that run from under 4 kWh to beyond 60 kWh. Where inverter makers add batteries to sell inverters and car makers add batteries to sell an ecosystem, AlphaESS builds the whole storage system as the product. The trade-off is name recognition: it is a specialist known to installers far more than to homeowners, so buyers meet it for the first time on a quote.

AlphaESS questions, answered

Who is AlphaESS, and should the name being unfamiliar worry me?
AlphaESS is a dedicated energy-storage manufacturer with a long-standing Australian arm — unfamiliar to homeowners mostly because it does not sell anything else you would have bought. Specialist brands live or die on installer relationships rather than advertising, so the more useful question than “have I heard of it” is how long your installer has been fitting and supporting them.
Is an AlphaESS battery eligible for the federal rebate?
Model-by-model, like every brand — Clean Energy Council listing is per configuration, and with a range as wide as SMILE the wrong variant is an easy mistake. Ask the installer to show you the exact quoted model on the current approved list before signing anything.
What makes the SMILE range different from other home batteries?
Span. Most brands sell one or two configurations and size you into them; SMILE runs from compact single-phase units to three-phase systems beyond 60 kWh. That flexibility is genuinely useful for households that do not fit the standard mould — and it puts more weight on the installer specifying the right point in the range rather than the one they have in stock.
Can AlphaESS handle a three-phase home properly?
The three-phase SMILE families are a real strength, with multiple inverter sizes and storage that scales well past what single-unit brands offer. The detail to pin down is blackout behaviour: whether all three phases stay live or only one depends on the specific configuration and switchboard wiring, so have the quote state which circuits and phases hold up.
Can I add an AlphaESS battery to solar I already own?
SMILE systems are integrated battery-and-inverter designs, so the usual path is the system replacing or sitting alongside your existing inverter arrangement rather than bolting onto it. Whether that is sensible depends on the age of your current inverter — if it is nearing end of life, an integrated replacement can be the tidier outcome. Ask for the design to be justified either way.
What happens to an AlphaESS system in a blackout?
Backup-capable configurations switch over automatically and hold up the circuits wired to the backup side; how much of the house that covers is a design decision made when the system is specified, not a property of the brand. With a range as wide as SMILE the sensible move is to make the quote state the backup scope circuit by circuit, because two AlphaESS systems can behave very differently in an outage.
How established is AlphaESS in Australia?
It runs a dedicated Australian arm with local distribution and support rather than selling through an importer alone, and its systems have been installed here across many years of the home-battery market. What it lacks is consumer advertising, which is why homeowners rarely know the name until a quote arrives. Judge it by the installer relationship and the local support chain, because that is how specialist brands actually deliver.
Does AlphaESS work with virtual power plants in Australia?
Several Australian programs accept AlphaESS systems, but acceptance is per-model and per-retailer rather than blanket. If VPP income is part of your maths, get the specific program named on the quote and confirm your exact configuration is accepted before you commit — afterwards is too late to discover a mismatch.
