Decision evidence

What the documents establish

Published evidence, source-reviewed non-disclosure and unresolved questions remain separate from the product score.

Usable capacity

Stated depth of discharge: 100%. Published usable energy: 16 kWh in the scored configuration. These values may have different measurement conditions.

16 kWh usableScored configuration: RESU 16H Prime. Published range 9.6–16 kWh.

The stated depth of discharge and published usable energy can have different test conditions or configuration limits. They do not by themselves establish nominal capacity or a reserve that is always inaccessible. Delivered AC energy and runtime also depend on the inverter, settings and loads.

The score uses the highest-capacity current Prime model. The 32 kWh two-unit maximum is supporting context rather than the scored product.

The blackout score is a standalone benchmark of outage resilience only - it re-weights sourced specs already scored in this product’s pillars (backup tier, switchover, surge strength, backup power, off-grid recharge) and never affects the overall score. Dots show the full battery fleet; the marker is this product.

Strong evidence coverage

31 of 31 scored criteria link directly to a published source.

Values marked estimated, derived, or not found remain visible on the audit sheet and do not carry the same evidential weight as a linked source. Coverage measures direct links, not an independent guarantee that a claim is correct.

    AU Grid and installation context

    Current text
    LG's current Australian compatibility list names both Prime models with GoodWe GW5K, GW8.6K and GW9.99K EHB-AU-G11 (DSP 30 and ARM 07 or above), the Solis S6-EH3P(5-10)K-H-AU (software V02B38D01; an LG three-phase box must be installed with Prime and the inverter must be manufactured after 15 September 2023) and the SMA SBS5.0 (software 3.12.23.R or above; backup use is available but the battery will not charge during a blackout). Brands are shown by logo in the list. The list states that a non-approved inverter voids the LG warranty. The stored reciprocal path targets the exact reviewed GW9.99K-EHB-AU-G11 record and carries the required firmware boundary.

    AU Warranty conditions

    Current text
    labour: Installation labour is not promised.; registration: 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.; remedy: Under Article 6.1 LG decides whether to repair or to replace defective Products with refurbished parts equal in value. Under Article 6.4, if the Products are no longer commercially available, LG may instead supply equivalent equipment or refund the remaining depreciated purchase price, defined as the price paid by the Reseller or Certified Installer.; removal reinstallation: Removal and reinstallation are not promised.; transferability: No express subsequent-owner transfer right is stated. Article 11 states that the Warranty applies only to the Buyer who purchased the Products for their own use.; transport: Ordinary claim freight is not an unconditional entitlement.

    AU Support Note

    Current text
    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; the same notice states that the Home Owner Service is discontinued and is not provided by enblock Manager. Article 7 of the governing Australian Prime warranty permits LG to provide remote firmware updates without notice; these may briefly interrupt battery operation. Internet access and registration are conditions for the full warranty term, with at least five years of warranty stated without them. Article 7 still names the RESU Monitor website for registration, and the documents reviewed do not state whether commissioning through enblock Manager counts as that registration. This is a warranty condition, not an offline operating guarantee or a minimum security-support period. The 16H Prime installation manual (Version 3.2, 66 pages) was reviewed on 7 October 2026; its English sections state no firmware-signing, secure-boot or vulnerability-disclosure terms. Firmware signing, secure boot and a product vulnerability-disclosure policy remain unestablished in this bounded review.
