Outcome	Available in Australia	Available in Australia
Checked	2026-08-06	2026-08-29
Certifications	The 29 July 2026 regulator export lists RESU 10H Prime and RESU 16H Prime with current approval through 12 June 2027.	The exact BAT-10.1P datasheet lists IEC 62619, IEC 63056, IEC 62040 and UN 38.3; the SMILE-G3-S5 AU system datasheet lists AS 4777.2 and IEC 62109.
Warranty scope	Australia; the Prime warranty provides ten-year product cover and 70% retained energy until 32 MWh for 10H Prime or 54 MWh for 16H Prime, whichever comes first, subject to its terms.	Australia; the 11 October 2024 warranty names SMILE-G3-S5 and BAT-10.1P with a ten-year term, 70% retained capacity and a 3.12 MWh/kWh throughput condition for eligible installations from 1 November 2024.
Warranty remedy	Repair, replacement with refurbished equal-value parts, an equivalent product or a depreciated refund at LG's option.	Repair or replacement at AlphaESS's option.
Labour and reinstallation	Installation labour is not promised. Removal and reinstallation are not promised.	Installer travel and on-site labour are excluded. Removal and reinstallation are not promised.
Freight	Ordinary claim freight is not an unconditional entitlement.	Replacement-parts freight is covered for an accepted claim.
Transfer and registration	No express subsequent-owner transfer right is stated. Registration and internet access are required for the full term so LG can provide firmware updates; the warranty states at least five years without them.	The warranty is non-transferable except where the products remain installed in a building, in which case it transfers to a later purchaser of that building. Serial registration before a claim, and installation by an SAA-accredited installer with a valid Alpha Installer ID, are required.
Grid/network approval evidence	LG's current Australian compatibility list names both Prime models with GW5K, GW8.6K and GW9.99K EHB-AU-G11. The stored reciprocal path targets the exact reviewed GW9.99K-EHB-AU-G11 record and carries the required firmware boundary.	The exact AU system is a 5 kW, 230 V single-phase hybrid under AS 4777.2. Current project approval and installer eligibility remain installation-specific.
Local product pathway	No separate local pathway recorded	No separate local pathway recorded
Buyer evidence	Ready (100% direct coverage): Local availability, buyer evidence, and the publication threshold are confirmed.	Ready (100% direct coverage): Local availability, buyer evidence, and the publication threshold are confirmed.
Safety notice	The reviewed Australian recall names older RESU3.3, RESU6.5, RESU10, RESU13, RESU7H and RESU10H Type-C/Type-R models plus named S/A modules. RESU 10H Prime and RESU 16H Prime are not named. Source	No model-specific notice recorded
Review note	RESU Prime remains separately listed on LG Energy Solution's Australian product surface and on the current Australian approved-battery export. It is not the successor identity for enblock E15.5. LG discontinued RESU Monitor on 31 December 2024 and states that its functions continue through enblock Manager.	AlphaESS's current 2026 Australian brochure lists SMILE-G3-S5/B5 with both BAT-10.1P and BAT-9.3S. The battery options coexist; neither is presented as the formal successor to the other.

Australia purchase checks

Make the shortlist quote-ready

These checks sit beside the benchmark score. They are site, tariff and contract questions that no product score can settle.

Lock the exact model and installation-date listing.
Ask for every model number to appear on the quote and order. The Clean Energy Council product lists are live: STC creation requires listed products at installation, and network requirements may also depend on current approval.
Obtain the site-specific connection settings.
Have the retailer state the supply phase, inverter connection limit, export limit and any export-control cost. The local network connection agreement, not a generic datasheet, determines those settings. See the Australian Government's connection guidance.
Test savings against the household, not a brochure.
Ask which bills or interval data, tariff, feed-in rate, export limit and future loads support the savings and payback claim. Self-consumed electricity and tariff timing usually matter more than a headline feed-in rate. See the system sizing and battery savings guidance.
Specify the operating outcome.
Define the usable energy, output power, backed-up circuits and outage behaviour. Confirm whether VPP participation, an internet connection, or an additional controller changes the configuration, reserve level, warranty or support path.
Name the party responsible after installation.
Keep the retailer, installer, manufacturer warranty and escalation path in the contract. Australian Consumer Law guarantees apply separately from any manufacturer warranty; where one business supplied both product and installation, it is generally responsible for the remedy. See the ACCC guidance.
