What we can tell you

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

16.56 kWh sits between the smaller home (10 to 15 kWh) and medium home (20 to 30 kWh) bands.
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: 16.56kWh; How much energy it stores for you to use
Continuous power: 7.65kW; How much it can run at once: most of a home, but not everything at full tilt
Round-trip efficiency: 96%; 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; 80% of capacity guaranteed at the end of it
Battery chemistry: LFP; Lithium iron phosphate, the long-cycle-life type
