It is suited to marine, vehicle and off-grid applications where independent battery banks must be maintained in isolation.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eIsolates up to three battery banks from a single charging source, preventing cross-discharge between banks.\u003c\/li\u003e\n  \u003cli\u003e100A continuous current rating across three outputs (3AC configuration).\u003c\/li\u003e\n  \u003cli\u003eDiode-based isolation requires no active switching or control wiring, making installation straightforward.\u003c\/li\u003e\n  \u003cli\u003eAluminium heatsink body dissipates heat generated by the diode voltage drop during charging.\u003c\/li\u003e\n  \u003cli\u003eCompact and robust construction suitable for permanent installation in vehicles, vessels and off-grid enclosures.\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard alternator and battery charger outputs without requiring additional control signals.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eThe Argodiode 100-3AC uses Schottky diodes to split a single charging input across three battery outputs. Current flows freely from the charger or alternator to each battery bank, but the diodes block any reverse flow, so a depleted bank cannot draw from a charged one. This is the fundamental advantage of diode isolation over simple paralleling or relay-based systems: no control logic is needed and isolation is always maintained regardless of load conditions.\u003c\/p\u003e\n\n\u003cp\u003eThe trade-off with diode isolators is a voltage drop of approximately 0.5V to 0.7V across the diodes. In practice, this means the battery banks will charge to a slightly lower terminal voltage than the source output. Where this matters, the alternator regulator or charger output voltage should be set 0.5V to 0.7V higher than normal to compensate. This is a standard consideration for any diode isolator installation and should be factored in during commissioning.\u003c\/p\u003e\n\n\u003cp\u003eThe 100A rating applies to the total input current. With three outputs, the current is distributed across the banks according to their state of charge. The aluminium body acts as the heatsink and must be mounted to a surface that allows adequate heat dissipation, particularly at sustained high charge currents.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSKU: ARG100301000R\u003c\/li\u003e\n  \u003cli\u003eConfiguration: 1 input, 3 outputs (3AC)\u003c\/li\u003e\n  \u003cli\u003eMaximum input current: 100A\u003c\/li\u003e\n  \u003cli\u003eNumber of battery banks: 3\u003c\/li\u003e\n  \u003cli\u003eWeight: 0.8 kg\u003c\/li\u003e\n  \u003cli\u003eGTIN: 8719076019046\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eMarine installations requiring separate starter, domestic and bow thruster battery banks charged from a single alternator.\u003c\/li\u003e\n  \u003cli\u003eMotorhomes and campervans with split habitation and engine start battery systems plus an auxiliary bank.\u003c\/li\u003e\n  \u003cli\u003eOff-grid cabins or vehicles where multiple battery banks serve different loads and must remain isolated.\u003c\/li\u003e\n  \u003cli\u003eCommercial vehicles with auxiliary equipment requiring a dedicated battery bank independent of the starter battery.\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 100-3AC diode battery isolator\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eInstallation Notes\u003c\/h3\u003e\n\u003cp\u003eThe Argodiode must be mounted on a thermally conductive surface to allow heat dissipation from the aluminium body. Ensure all cabling is correctly rated for the maximum current and that appropriate fusing is fitted on the input feed. Account for the diode voltage drop when setting the charge source output voltage. Installation should be carried out by a qualified electrician or marine electrical engineer familiar with multi-bank charging systems. For marine installations, follow the relevant BMEA or IEC wiring standards applicable to the vessel.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":59863661904206,"sku":"ARG100301000R","price":49.49,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/VoltaconSolar_-_ARG100301000R_-_Argodiode_100-3AC_3_batteries_100A_Retail.webp?v=1781183065","url":"https:\/\/voltaconsolar.com\/products\/victron-argodiode-100-3ac-battery-isolator","provider":"VoltaconSolar","version":"1.0","type":"link"}
