BYD HVE 12.8-1

A 12.86 kWh home battery — smaller home size, the 10–15 kWh band.

Installed in Perth, after rebates: ~$7,429; Typical estimate — your own quote will vary
WA Battery Scheme rebate: Depends on your inverter; The scheme needs a Synergy-approved inverter — we don't know yours
Usable capacity: 12.86kWh; Smaller home size — the 10–15 kWh band

What we can tell you

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

12.86 kWh sits in the smaller home band (10–15 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 How much energy it stores for you to use: 12.86kWh
Continuous power How much it can run at once — most of a home, but not everything at full tilt: 7.65kW
Round-trip efficiency How much of the energy you store comes back out: 92%
Depth of discharge How much of the battery you can actually use: 90%
Warranty 60% of capacity guaranteed at the end of it: 15yr
Battery chemistry Lithium iron phosphate — the long-cycle-life type: LFP

What it costs in Perth

$10,900

Typical installed price, before rebates

WA Battery Scheme: Depends on your inverter
Federal STCs: −$3,471
You’d pay about: $7,429

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: 10–15 kWh
Medium home: 20–30 kWh
Big home: 30–40 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.
