What we can tell you

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

4.6 kWh is below the smaller-home band.
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: 4.6kWh; How much energy it stores for you to use
Continuous power: 5kW; How much it can run at once: most of a home, but not everything at full tilt
Round-trip efficiency: 97%; 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: 5yr; 80% of capacity guaranteed at the end of it
Battery chemistry: LFP; Lithium iron phosphate, the long-cycle-life type

Warranty and support

This warranty covers repairs or replacements of defective products for 5 years. It excludes damage from improper installation. Claims must be made via the KSTAR website or email.

Product: 5 years; transferable; full replacement
At year 10: At least 80% of capacity
Throughput: 2.62 MWh
Installation: Must be installed by an SAA-accredited installer
Support: Not verifiedWe have not verified this brand's Australian support structure. Confirm warranty arrangements with the manufacturer or your installer.

WA Battery Scheme eligibility

Not eligible

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
