Notes from our research: Listing is thin and contradictory: its description is a generic range blurb whose 'What's Included' lists 2x DMEGC 465W (DM465G12RT-G48HBB), a Hoymiles HMS-800-2WB, Fastensol plastic bases/mini rails/end clamps and 2x Staubli 2m DC cables, which does not match a 1x475W HF-800-WB kit. ENA (CITYP/21392) lists '1x DME-475W + HF-800-WB'; inverter taken from ENA and the attached HF-800-WB tech sheet. DMEGC makes a DM475G12RT-G48HBB (Voc 36.74 V, 23.8%), but no source confirms it is the kit's panel. Contents, cable and plug left null because the listing gives no kit-specific values. City Plumbing's tech sheet is a generic HiFlow manual that says the Flex-S3 AC lead is 'Plug and Play-CEE7/7' (Schuko) while the listing says the kit fits a UK 3-pin socket; plug type taken from the listing. Listings name 'Fastensol' mounting while the attached tech sheet describes a 'Plug in Solar Mounting Kit 2.0' with hooks, expansion bolts and wire safety ropes (12-year bracket warranty); tilt is adjustable but no range is given. 'Years Guaranteed: 10' on the listing does not say what it covers (recorded as kitYears). The HF-800-WB has one MPPT with one input, so two-panel kits are wired in series (tech sheet says 'Connect two PV modules in series'). maxInputWPerChannel left null: Hoymiles only gives 'commonly used module power 320 to 520+ W'.
