Usable capacity: 1.93kWh; Below the smaller-home band

What we can tell you

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

1.93 kWh is below the smaller-home band — this is one module of a larger stack.
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: 1.93kWh
Continuous power How much it can run at once — the essentials, not the whole house: 2.4kW
Round-trip efficiency How much of the energy you store comes back out: 96%
Depth of discharge You can use the whole battery, not just part of it: 100%
Warranty 80% of capacity guaranteed at the end of it: 20yr
Battery chemistry The cell type inside it: Lithium Titanate (LTO)
