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#33 of 77 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.
