What we can tell you

Read from the figures on this page — no review written yet

149.8 kWh sits in the very big home band (40+ 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 How much energy it stores for you to use: 149.8kWh
Round-trip efficiency How much of the energy you store comes back out: 92%
Depth of discharge How much of the battery you can actually use: 90%
Warranty 80% of capacity guaranteed at the end of it: 10yr
Battery chemistry Lithium iron phosphate — the long-cycle-life type: LFP
Size and weight Installed weight: 35kg

What it costs in Perth

$134,820

Typical installed price, before rebates

WA Battery Scheme: Depends on your inverter
Federal STCs: −$6,943
You’d pay about: $127,877

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.
