What the documents establish
Published evidence, source-reviewed non-disclosure and unresolved questions remain separate from the product score.
Capacity guarantee: minimum retained at year 10
No year-by-year capacity schedule is published for this product - the manufacturer guarantees only this end-of-term minimum, not a specific decline curve.
Blackout protection
67 / 100#34 of 90 batteriesPartial (essential loads)
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.

Market context
Global evidencechange in the site menu
Global benchmark. This scorecard is benchmarked globally. A global score does not imply local availability, certification, warranty coverage, or installer compatibility.
Benchmark anchor. Capacity range describes supported configurations; the score remains anchored to the named reviewed reference configuration, not the largest stack. Scored model: HM6 with two 5.12 kWh modules (10.24 kWh nominal) · checked 2026-07-31. Evidence.
Sources & references · checked 2026-09-01
Strong evidence coverage
17 of 17 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.

Rings, outside in: manufacturer claim, certified or regulator-listed, third-party source. The centre is review.solar's own measurement, empty for every product today. Warranty terms and design facts that rest on the maker's own word are counted beside the rings; a reviewed absence, or one that reaches beyond the maker's claim, stays in them. How the evidence puzzle works
Record revision. ESY SUNHOME HM5/HM6 datasheet v1.5 and AU single-phase warranty v4.5. First-market US and DE overlay review 2026-09-01: official regional catalogues recorded; Australian overlays and scores unchanged. Australian warranty reader review 4 October 2026: the accepted v4.5-named URL now serves an eight-page document whose PDF metadata title identifies v4.6/November2025; filename, metadata and upload date do not establish retroactive contract supersession. It names HM6 and the scored10.24 kWh battery. ESY SUNHOME AUSTRALIA PTY LTD provides the Australian warranty. Installation must occur within six months of production; capacity expansion is permitted only in the first year, and new modules share the original remaining warranty and performance conditions. Continuous Internet or4G monitoring and commissioning connection are required; outages require prompt notification and supporting local evidence. Ten-working-day failure notification and one-month diagnosis-to-claim deadlines are separate. Accepted reasonable processing/parts/shipping/dismantling/installation costs are capped at A$180 plus GST per claim, subject to documentary evidence; invalid claims allocate the specified claim costs to the customer up to the same cap. Routine maintenance and personnel travel/transport/accommodation are excluded. Repair may use refurbished parts; remaining warranty does not reset. Transfer requires the original site and simultaneous ownership transfer of site and product. The70% available-capacity warranty and10.24 kWh/43.0 MWh throughput row remain distinct from independently tested cycle life or AC efficiency. ACL rights are preserved; current market and technical scores remain unchanged. Current maker-linked HM5/HM6 sheet reviewed4October2026: PDF metadata title EN-single-page HM5&6-20260119, modified26January2026; upload path does not establish supersession. PDF2 explicitly names HM6 and the two-module HM6-10 rated10.24 kWh configuration. Manufacturer declares at least6000 cycles at25 C to70% SOH;6000 is scored as its conservative lower bound under unchanged battery rubric2.10. Depth of discharge, C-rate and full protocol remain unspecified; no independent reliability claim. Earlier cycle-life absence is superseded within this document scope. Natural cooling and operating derating above45 C remain distinct from active suppression. PDF1 repeats built-in extinguisher and VPP-compatible marketing, without mechanism/BOM or named live-program/API scope.97.8% maximum and99.9% MPPT figures remain inverter efficiencies, not batteryDC orAC-system round-trip efficiency. Existing warranty, benchmark, market states/dates and global verification date remain unchanged. HM6 manual reader integration4October2026: section6.6.2/PDF19 explicitly puts the system in standby without output during OTA upgrades and requires grid supply. Section5.1.4/PDF11 remote inverter/battery temperature monitoring and control uses backend instructions/BMS and requires the optional Wi-Fi communication dongle; it does not establish terminal-specific NTC protection or local automatic thermal control. Section7/PDF19 ESYSUNHOME Tool access is for inverter manufacturers or authorised maintenance personnel over RS485-to-USB, not a publicly documented owner or third-party API. PDF6 specifies derating above45 C within the -25to60 C operating range. Existing firmware disclosure band55 is supported by the exact OTA documentation. Current public download/app/cloud/privacy surfaces provide no device vulnerability-policy/support-period/update-signing evidence in this scoped review; generic privacy/browser SSL and secure/reliable marketing are not device-security documentation. No security vulnerability or absent security-control finding. Firmware release/version entitlement, public API, named VPP, protection hardware and independent reliability remain separate open gates.

AU Warranty conditions
- Current text
- labour: Accepted dismantling and installation labour shares the combined A$180 plus GST per-claim cap with processing, parts and shipping; this is not an uncapped site-labour promise. Personnel travel, transport and accommodation are excluded.; registration: Commissioning requires stable Internet or4G connection and continuous online monitoring. Network outage/faults require prompt notification and supporting photos/logs; offline claims require authorized site inspection/data collection. Report failure within ten working days and submit a claim within one month of fault diagnosis; these are separate clocks. Provide purchase,serial,installation/commissioning evidence and signed commissioning report. Installation within six months of production and first-year-only capacity expansion are warranty conditions; added modules inherit the original remaining term.; remedy: Repair or replacement, potentially with refurbished goods/parts. Repaired or replaced products retain the original remaining performance warranty without extension. Accepted reasonable claim costs require documentary evidence and are capped at A$180 plus GST per claim; invalid-claim costs are allocated to the customer up to the same stated cap, subject to ACL rights.; removal reinstallation: Accepted faulty-battery dismantling and installation shares the combined A$180 plus GST per-claim cap; no separate unlimited removal/reinstallation entitlement.; transferability: Transfer requires the product to remain at its original installation site and simultaneous transfer of ownership of both site and product. No later-owner registration deadline is specified in the reviewed policy.; transport: Accepted replacement parts/product shipping shares the combined A$180 plus GST per-claim cap. Personnel travel/transport/accommodation are excluded; documentary cost evidence is required.
