Notes from our research: No mounting is listed in the box (the kit is described for garden, patio, flat roof or outbuilding use). The two panels are wired in series into the single HF-800-WB input. No ENA reference was supplied; the Hoymiles HF-800-WB is ENA-listed in other kits, but this exact kit's registration is unconfirmed. JA electrical values come from a distributor's copy of the JA datasheet (sun.store), not jasolar.com directly.
