What we can tell you

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

5.12 kWh is below the smaller-home band: this is one module of a larger stack.
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: 5.12kWh; How much energy it stores for you to use
Continuous power: 3.6kW; How much it can run at once: the essentials, not the whole house
Round-trip efficiency: 95%; How much of the energy you store comes back out
Depth of discharge: 80%; How much of the battery you can actually use
Warranty: 5yr; How long the manufacturer stands behind it
Battery chemistry: LFP; Lithium iron phosphate, the long-cycle-life type

What it costs in Perth

$4,608

Typical installed price, before rebates

WA Battery Scheme: Depends on your inverter
Federal STCs: −$1,357
You’d pay about: $3,251

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 below the smaller-home band. The WA rebate caps at 10 kWh, but that is a rebate limit, not a sizing guide.
