What we can tell you

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

51.2 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: 51.2kWh
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 70% of capacity guaranteed at the end of it: 10yr
Battery chemistry Lithium iron phosphate — the long-cycle-life type: LFP
Size and weight 360 × 615 × 175 mm — roughly a large suitcase on the wall: 35kg

WA Battery Scheme eligibility

Conditional

Synergy SSL inverter pairing, VPP participation and state-rebate qualification for this battery. Rebate and STC amounts are shown in the pricing panel.

AC-coupled system: needs a gateway device on the Synergy SSL (e.g. SMA, Redback), or a same-brand inverter + battery pair (Sungrow or Fronius) for shared compliance. Without one, export is limited to 1.5kW and VPP/DEBS/rebate/loan are unavailable — and third-party gateways can struggle to meet compliance testing. Any later addition to an AC-coupled system triggers whole-of-site compliance, so for many homes replacing toward a hybrid (DC-coupled) inverter is the sounder path. AC vs DC coupling

CSIP-AUS compliant
Inverter must be CSIP-AUS compliant under the current WA framework.
Synergy SSL approved inverter
Needs pairing with a Synergy SSL approved inverter.
VPP activation ready
VPP activation requires a Synergy SSL approved inverter.
WA Battery Scheme rebate
Requires Battery Rewards participation under the current WA framework.
Synergy Battery Rewards
Requires a CSIP-AUS compliant system and reliable internet.
Interest-free loan
Not eligible for interest-free financing.

Under current WA rules, new rebate applications require VPP enrolment and CSIP-AUS compliance. How the scheme works · Estimate VPP earnings

Typical installed price, before rebates

WA Battery Scheme: Depends on your inverter
Federal STCs: −$6,943
You’d pay about: $39,137

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.
