LG Energy Solution RESU 16H Prime

A 15.2 kWh home battery.

Installed in Perth, after rebates: ~$10,450; 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: 15.2kWh; Between the smaller home and medium home bands

What we can tell you

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

15.2 kWh sits between the smaller home (10–15 kWh) and medium home (20–30 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 How much energy it stores for you to use: 15.2kWh
Continuous power How much it can run at once — most of a home, but not everything at full tilt: 5kW
Round-trip efficiency How much of the energy you store comes back out: 98%
Depth of discharge You can use the whole battery, not just part of it: 100%
Warranty 70% of capacity guaranteed at the end of it: 10yr
Battery chemistry The cell type inside it: Lithium-Ion

What it costs in Perth

$14,440

Typical installed price, before rebates

WA Battery Scheme: Depends on your inverter
Federal STCs: −$3,990
You’d pay about: $10,450

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 sits between the smaller home and medium home bands. The WA rebate caps at 10 kWh, but that is a rebate limit, not a sizing guide.

Does waiting change the rebate?
