What we can tell you

Read from the figures on this page. No review written yet.

18 kWh sits between the smaller home (10–15 kWh) and medium home (20–30 kWh) bands.
It is CEC-approved, which is a condition of both the federal STC discount and the WA Battery Scheme.
We can't score it: a value score needs a price and full specs, and without them any number would be guesswork.

Key specs, in plain terms

The numbers that matter for a home. The full datasheet is below.

Usable capacity How much energy it stores for you to use: 18kWh
Continuous power How much it can run at once — enough for a whole home, air conditioning included: 12kW
Round-trip efficiency How much of the energy you store comes back out: 100%
Depth of discharge How much of the battery you can actually use: 85%
Warranty 70% of capacity guaranteed at the end of it: 15yr
Battery chemistry Lithium iron phosphate — the long-cycle-life type: LFP

What it costs in Perth

$16,200

Typical installed price, before rebates

WA Battery Scheme: Depends on your inverter
Federal STCs: −$4,429
You’d pay about: $11,771

The WA Battery Scheme (up to $1,300) needs a Synergy-approved inverter and VPP enrolment. We don't know which inverter you'd pair this with, so it isn't deducted above — ask your installer. STCs assume about $39.9 a certificate. Estimates only; your quote will vary.
