Together with five 18650 cells and 3 W of solar across three sides of the enclosure, the repeater keeps going in locations where other setups give up – the vertical front panel still delivers yield even when the roof is covered in snow. And should the battery ever run down after long spells of bad weather, the MR2 enters deep sleep and wakes up on its own once the sun has recharged the battery. No ladder trips, no manual reset.\u003c\/p\u003e\n\n\u003ch3\u003eIncluded in the kit\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1 × MR2 solar mesh repeater board (multi-chemistry, MPPT, RED\/CE-certified)\u003c\/li\u003e\n\u003cli\u003e3 × solar panel 6 V \/ 1 W, ETFE, monocrystalline\u003c\/li\u003e\n\u003cli\u003e1 × solar connector board (parallel connection of the three panels)\u003c\/li\u003e\n\u003cli\u003e1 × adapter cable JST-PH 2.0\u003c\/li\u003e\n\u003cli\u003e1 × battery cable – \u003cstrong\u003echoose variant:\u003c\/strong\u003e with LiFePO4 or Li-Ion protection module (incl. temperature sensor), or without BMS (open ends – for LTO and Na-Ion builds)\u003c\/li\u003e\n\u003cli\u003e1 × antenna kit 868 MHz ground plane: 5 × brass tubes Ø 2 mm cut to length and tuned (1 × radiator, 4 × radials), SMA bulkhead jack, pigtail SMA → U.FL\u003c\/li\u003e\n\u003cli\u003e1 × BLE adhesive antenna 2.4 GHz (configuration and OTA updates via app)\u003c\/li\u003e\n\u003cli\u003e4 × mounting screws stainless steel A2 for the MR2\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe antenna is measured in the assembled roof: \u003cstrong\u003eSWR ≈ 1.1 across the 868 MHz band\u003c\/strong\u003e – enclosure integration barely detunes it.\u003c\/p\u003e\n\n\u003ch3\u003eAlso required\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e5 × 18650 cells – LiFePO4 or Li-Ion, matching the chosen battery cable variant (without-BMS variant: for LTO\/Na-Ion – details in the \u003ca href=\"https:\/\/docs.inhero.de\/en\/mr2\/battery-guide\/\" target=\"_blank\" rel=\"noopener\"\u003ebattery chemistry guide\u003c\/a\u003e).
