What we can tell you

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

12.48 kWh sits in the smaller home band (10 to 15 kWh).
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: 12.48kWh; How much energy it stores for you to use
Continuous power: 0.5kW; How much it can run at once: the essentials, not the whole house
Round-trip efficiency: 92%; How much of the energy you store comes back out
Depth of discharge: 100%; You can use the whole battery, not just part of it
Warranty: 10yr; 80% of capacity guaranteed at the end of it
Battery chemistry: LFP; Lithium iron phosphate, the long-cycle-life type

What it costs in Perth

$8,800

Typical installed price, before rebates

WA Battery Scheme: Depends on your inverter
Federal STCs: −$3,352
You’d pay about: $5,448

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.

Which size band is your home?

Usable capacity, for one battery system

Smaller home: 10 to 15 kWh
Medium home: 20 to 30 kWh
Big home: 30 to 40 kWh
Very big home: 40+ kWh

This battery is one unit in the smaller home band. The WA rebate caps at 10 kWh, but that is a rebate limit, not a sizing guide.
