What we can tell you

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

15 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: 15kWh; How much energy it stores for you to use
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; How long the manufacturer stands behind it
Battery chemistry: LFP; Lithium iron phosphate, the long-cycle-life type
Size and weight: 56kg; Installed weight

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.

This battery is AC-coupled. To get the WA rebate, the interest-free loan, VPP payments or DEBS export credits, it needs a gateway device from Synergy's approved list (for example SMA or Redback), or an inverter and battery from the same brand (Sungrow or Fronius). Without one, exports are capped at 1.5kW.

Some third-party gateways struggle to pass compliance testing, and adding anything to an AC-coupled system later means the whole system has to be re-checked. For many homes, switching to a hybrid (DC-coupled) inverter is the simpler 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

What it costs in Perth

$13,500

Typical installed price, before rebates

WA Battery Scheme: Depends on your inverter
Federal STCs: −$3,950
You’d pay about: $9,550

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.
