The data
DC-coupled battery
Stores DC energy and relies on system power electronics outside the battery product for household AC.

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. Capacity figure based on the sourced usable capacity of the base configuration; modular systems scale with additional modules.

Global benchmark. This scorecard is benchmarked globally. A global score does not imply local availability, certification, warranty coverage, or installer compatibility.
Benchmark anchor. The score and displayed range remain inside the exact source and market boundary recorded by the 13 August 2026 sprint. Scored model: T-BAT HS46.8 · checked 2026-09-01. Evidence.

Strong evidence coverage
16 of 16 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.

- de.solaxpower.com/products/t-bat-sys-hv-s3-6.html returns 404 (checked 9 October 2026). The German residential battery page (de.solaxpower.com/residential-batteries.html, checked 9 October 2026, last modified 10 September 2026) lists T-BAT HS7.2 to T-BAT HS46.8 in its product specifications with German-market values, such as a 3.6 kWh battery module of 10 kg, which differ from the Australian values and are not transferred. The German warranty terms (EU DE V1.7, listed 23 September 2026, checked 9 October 2026) name the T-BAT-SYS-HV-S3.6 series with module TP-HS3.6 and do not name T-BAT HS46.8. The live German TSYS-HS51 page is a different identity and is not transferred onto T-BAT HS46.8. T-BAT H 23 V2 is a different family. Overlay stays not_reviewed: the maker lists the configuration on this page, but no governing warranty naming it and no local German support source was established.

The US product catalogue (us.solaxpower.com/our-products.html) and the US residential battery page (us.solaxpower.com/residential-batteries.html), both checked 9 October 2026, name T-BAT-SYS-HV-5.0 as the only residential battery listed. The US limited warranty PDF (text version V1.6, valid from 15 January 2025, US and Canada only) names T-BAT-SYS-HV-5.0 as its only battery module. The US warranty web page (us.solaxpower.com/warranty.html, checked 9 October 2026) lists the T-BAT-SYS-HV-S3.6 series with module TP-HS3.6 and no T-BAT HS model. Listing absence is not a maker statement that the model is not offered, so no not_offered status is proposed. TSYS-HS51 and T-BAT H V2 are different families and are not transferred.

US market evidencePrimary datasheetAU Warranty scope
- Current text
- Australia; the current linked SolaX warranty PDF explicitly names T-BAT HS7.2 through T-BAT HS46.8 for 10 years. Standard cover ends at 120 months from installation or 129 months from manufacture, whichever comes first. The stated NSW Peak Demand Reduction Scheme exception requires an installation approved by an Accredited Certificate Provider and guarantees 10 years from installation; it is not a general extension. Daily self-consumption and backup are limited to 6,000 cycles with 70% retained energy at 120 months from installation or 129 months from manufacture, whichever comes first; other applications use the model-specific throughput table.

Usable energy / DoD (%)Modularity & scalability+4 in JSON recordAU Warranty conditions
- Current text
- labour: Travel, subsistence, on-site installation, modification and normal maintenance are excluded; no uncapped third-party labour entitlement is stated.; registration: Authorised supply, installation, activation and registration conditions apply; claims require exact model, serial and installation evidence. Battery additions after one year require prior SolaX consent.; remedy: Software correction, repair on or off site, or an equivalent repaired, refurbished, upgraded or new substitute at SolaX's option.; removal reinstallation: Full removal and reinstallation costs are not stated as an unconditional entitlement.; transferability: No automatic subsequent-owner transfer right was found in the current linked terms.; transport: Normal ground transport in specified Australian areas is covered up to AUD 200 per case; excess and alternative transport costs remain with the claimant. Section 6 also quotes a standard service charge of AUD 150 (excluding GST) per case for a defective product found damaged after checking the returned product, requires contact with SolaX before a site visit, and does not clearly establish who pays or receives that amount. Where no damage is found after checking the returned product, SolaX invoices the claimant for the replacement unit plus delivery and associated service charges. Section 4 states that SolaX seeks reimbursement of labour, travel, delivery and replacement-unit costs where a replaced product is found free from defects or not covered.
