Growatt's own copy sits under /upload/, which Growatt's robots.txt disallows, so it was never requested. Its page 2 table prints, per column AXE 5.0L to AXE 50.0L (1 to 10 AXE 5.0L - C1 modules), the energy, nominal power, nominal charge/discharge current, peak power, dimension and weight, with general figures below. It is the edition before the "New" datasheet of 202506, which describes the newer module version. It notes that the AXE series has an EU model and a General model. The table was also read from a rendering to pair each figure with its column. Manufacturer claims, not independent tests.

Cited for the links from Growatt's global AXE LV Battery page to the AXE 5.0L datasheet (202401), the AXE 5.0L-C1 MSDS, UL1973 certificate and UN38.3 summary cited here. The page also links a new-version datasheet (202506), an AXE New&Old Version Differences Declaration (202502) and a 202506 user manual. Its feature list is marketing text.

Growatt's own AXE 5.0L Modular Battery datasheet, linked from the AXE LV Battery page on us.growatt.com and captured on September 25, 2026. Its columns name the systems as "AXE 10.0L" through "AXE 50.0L" built from the "AXE 5.0L - C1" module. System dimensions and weights include the battery base, so they differ from the user manual's figures, which exclude it. Prints no cycle life.

Cited as a labeled fallback: Growatt's own AXE New & Old Versions Differences Declaration (file dated 202502), the file Growatt's AXE LV Battery page links, in the copy hosted by the distributor PVGroup (pvgroup.pl, linked from its Growatt downloads page) and read there on September 30, 2026 after PVGroup's robots.txt allowed the path. The file prints Growatt's name and address; it is Growatt's document, not a distributor document. Growatt's own copy sits under a path Growatt's robots.txt disallows, so it was not requested. It sets out how the old and new AXE battery versions differ: carton, pack and cable labels (the new version carries an "E2" carton label and needs a 160A cable) and 120A against 160A per cluster. Its comparison tables are images. Manufacturer claims, not independent tests.

Own one? A verified review needs a receipt and a serial number photo, and counts 19× in the owner rating.
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.

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.

UL 1973: strongest qualifying evidence, counted once. Product-scoped manufacturer claim; issuer verification pending. Applies: CEC; UL 9540; UL 1973.
