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: 10 kWh in the scored configuration. These values may have different measurement conditions.

10 kWh usableScored configuration: APX 10.0P-S2 AU (two APX 5.0P-B1 modules). Published range 5–30 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.

Capacity range describes supported configurations; the score remains anchored to the named reviewed reference configuration, not the largest stack.

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.

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.

Global benchmark. This scorecard is benchmarked globally. A global score does not imply local availability, certification, warranty coverage, or installer compatibility.

Strong evidence coverage

15 of 15 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.

    AU Warranty conditions

    Current text
    labour: Contractual labour and compensation exclusions are subject to statutory liability and the instrument’s preserved Australian Consumer Law guarantees.; registration: Growatt-platform monitoring of the battery and charge/discharge device is required; the instrument reduces cover to three years without monitoring. Installation must finish within six months of Growatt delivery. Notify the supplier within 14 days of problem signs and submit the claim form within one month of failure, with original warranty card, purchase/installation invoices and signed commissioning report. Accumulated-discharge evidence is required for performance claims; an unmonitored claim requires qualified onsite inspection/data collection.; remedy: Growatt chooses repair, onsite repair or an equivalent-value replacement based on model and age. Repair or replacement retains the remaining original warranty period. During the latter five years, the instrument also allows pro-rata buyback or newer technology at a price payable by the customer. Australian Consumer Law guarantees are expressly preserved.; removal reinstallation: Removal and reinstallation are excluded.; transferability: The governing Australian warranty states that it is non-transferable.; transport: Contractual logistics-cost exclusions are subject to statutory liability and the instrument’s preserved Australian Consumer Law guarantees.
