This matters in practice because Schottky diodes have a lower forward voltage drop, typically around 0.3V to 0.5V less than standard diodes. In charging applications, this reduced drop means battery banks receive a voltage closer to the alternator or charger output, which is particularly important when charging lead-acid or AGM batteries that require accurate voltage regulation.\u003c\/p\u003e\n\n\u003cp\u003eThe isolator accepts a single input from an alternator or DC charger and splits the output to two battery banks through separate diode paths. Because the diodes are unidirectional, neither battery can discharge into the other, and a fault or deep discharge on one bank does not affect the other. The aluminium body acts as the heatsink and should be mounted to a flat metal surface or bulkhead to ensure adequate thermal performance at sustained high currents.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSKU: ARG120201020R\u003c\/li\u003e\n  \u003cli\u003eMaximum current: 120A\u003c\/li\u003e\n  \u003cli\u003eNumber of battery outputs: 2\u003c\/li\u003e\n  \u003cli\u003eDiode type: Schottky (2AC configuration)\u003c\/li\u003e\n  \u003cli\u003eCompatible system voltages: 12V and 24V\u003c\/li\u003e\n  \u003cli\u003eWeight: 0.8 kg\u003c\/li\u003e\n  \u003cli\u003eGTIN: 8719076019084\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eMarine vessels requiring separation of starter and domestic battery banks charged from a single alternator.\u003c\/li\u003e\n  \u003cli\u003eMotorhomes and campervans with separate engine start and leisure battery banks.\u003c\/li\u003e\n  \u003cli\u003eCommercial vehicles with auxiliary battery systems for refrigeration, tail lifts or other loads.\u003c\/li\u003e\n  \u003cli\u003eOff-grid installations where a single charger must maintain two isolated battery banks.\u003c\/li\u003e\n  \u003cli\u003e4x4 and overland vehicles with dual battery setups.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eWhat Is Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 x Victron Argodiode 120-2AC battery isolator unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eInstallation Notes\u003c\/h3\u003e\n\u003cp\u003eThe Argodiode should be mounted on a thermally conductive metal surface to allow heat dissipation at full rated current. Ensure all cable connections are correctly rated for 120A and that appropriate fusing is fitted on the input and each output circuit. Installation in marine and vehicle electrical systems should be carried out by a qualified electrician or accredited installer familiar with the relevant wiring standards. The voltage drop across the diodes should be accounted for when setting the alternator or charger output voltage to ensure batteries receive the correct charge voltage.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":59863661936974,"sku":"ARG120201020R","price":55.49,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/VoltaconSolar_-_ARG120201020R_-_Argodiode_120-2AC_2_batteries_120A_Retail.webp?v=1781183069","url":"https:\/\/voltaconsolar.com\/products\/victron-argodiode-120-2ac-battery-isolator-120a","provider":"VoltaconSolar","version":"1.0","type":"link"}
