Discover prints two body heights
The installation manual's Table 3-2 (page 12) prints "Height (body only) 920 mm", while its dimension diagram on the same page and the datasheet (808-0046 REV E) print 900 mm. The manual's table is recorded and the datasheet's 900 mm is kept as an alternative.
Printed in the manual's Table 3-2 (page 12) as "Height (body only) 920 mm", "Width 465 mm (18 31 in)" and "Depth (body only) 247 mm (9 72 in)" (the text layer drops decimal points); 948 to 978 mm high including feet and 271 mm deep including the wall-mount bracket. The installation manual is recorded as the primary source.
247 D × 465 W × 900 H mm
Printed as "Height (A) 900 mm (35.43 in) Width (B) 465 mm (18.31 in) Depth - body only (C) 247 mm (9.72 in)" in the datasheet.
Printed as "Up to 36 modules (579.6kWh) in parallel with Closed- loop communication"; the datasheet also says expandable up to 48 kWh with battery to battery parallel installations.

The Evidence score uses the priorities you choose. It counts published documents, such as certificates and warranty terms, and it compares a documented figure with the best documented figure of the same kind. It does not count owner reviews, and it is not a verdict on product quality or on how many people have reviewed it. A low score can mean little is documented, or that a documented figure is below the best of its kind. Undisclosed data scores 0.
Missing details. This number counts only the evidence recorded so far. The source review for this product is not finished, or the maker has not disclosed enough, so the number can only go up.
Missing for this product: Warranty energy disclosure evidence needed; Lifetime / capacity evidence needed; Cell model disclosure evidence needed.
48 V · Format not recorded · Rated capacity
The warranty term and the lifetime energy are each scored against the best documented value for a home storage battery: a value earns its share of that best, times the weight. A documented value always earns points; an undisclosed one earns 0.

CEC listing: full credit for the certificate criterion. Exact model found in the dated CEC equipment list. This is not a safety certification or system approval. Applies: CEC; UL 9540; UL 1973.
Research pending, 0 points: Warranty energy disclosure, Cell model disclosure.
Computed from public specifications and evidence records. Warranty duration is not service quality; certificate evidence points are not a safety rating. Compatibility and installation limits still apply.
