What we can tell you

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

4.5 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.
