Notes from our research: BYM1000 is rated 1000VA, above the 800W limit for plug-in solar in GB, and no ENA reference was supplied, so treat this kit as not plug-in compliant unless the inverter is export-limited and registered. Panel model not named on either kit page; Voltacon's standalone JA 465W panel is JAM54D41-465/LR, but this is not confirmed for this kit. The AC cable/plug is 'supplied according to destination', so plug type is not stated. Voltacon gives 450-750 W as the recommended PV input per channel (not a maximum), so maxInputWPerChannel is left null; max input current per channel is not given on the product page.
