The Hoymiles microinverter, mounted on the frame, converts it into 230 V mains power and feeds it through the supplied UK plug into your socket. Your appliances use that power first, and any surplus flows back out to the grid. Nothing is stored. If the grid goes down, the inverter switches off within a fraction of a second. That's a required safety feature, and it means the system produces nothing during a power cut. You can follow what your system generates, live and over time, in the Hoymiles app over Wi-Fi or Bluetooth.\u003c\/p\u003e\n\n\u003ch3\u003eWhere it goes\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eGardens, lawns and gravel on firm, level ground\u003c\/li\u003e\n  \u003cli\u003ePatios, yards and flat roofs that can carry the load\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eYou'll need a free area of about 3.65 × 1.13 m with open sky to the south. \u003cem\u003eThe Duo is not designed for balcony railings, walls, façades or pitched roofs.\u003c\/em\u003e\u003c\/p\u003e\n\n\u003ch3\u003eWhat's in the box\u003c\/h3\u003e\n\u003cp\u003eYour Duo arrives as three parts:\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSolar panels\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e2 × JA Solar JAM54D41-455\/LB, 455 W each, full-black n-type double-glass bifacial module\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eMounting kit box\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e2 × KSeng Zn-Al-Mg ballast mount set, one per panel, 20° fixed tilt (4 leg sets in total)\u003c\/li\u003e\n  \u003cli\u003eM6 stainless flange bolts with nuts\u003c\/li\u003e\n  \u003cli\u003e2 × 10 mm spanner\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eAccessories box\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e1 × Hoymiles HMS-800-2WB (HiFlow 800 Pro) microinverter, dual MPPT, Wi-Fi and Bluetooth\u003c\/li\u003e\n  \u003cli\u003e1 × AC connection lead with moulded UK plug (BS 1363) and 5 A fuse\u003c\/li\u003e\n  \u003cli\u003e1 × pair of 2 m DC extension leads, to reach the second panel\u003c\/li\u003e\n  \u003cli\u003e14 × UV-stable cable clips\u003c\/li\u003e\n  \u003cli\u003eConsumer-unit label\u003c\/li\u003e\n  \u003cli\u003eIllustrated assembly and user instructions\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eNot included: ballast.\u003c\/strong\u003e The frame is held down by weight, so you'll need 100–160 kg of concrete slabs or ballast blocks per panel (200–320 kg for the Duo), depending on how exposed your site is.
