It is suited to marine, vehicle and off-grid applications where battery bank isolation is required without the complexity of relay-based systems.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eIsolates two battery banks from a single charging source using Schottky diodes, preventing cross-discharge between banks.\u003c\/li\u003e\n  \u003cli\u003eRated at 80A continuous current, suitable for medium-duty alternator and charger installations.\u003c\/li\u003e\n  \u003cli\u003e2AC configuration provides two isolated outputs from a single input, each capable of carrying the full rated current.\u003c\/li\u003e\n  \u003cli\u003eSchottky diode construction reduces forward voltage drop compared to standard silicon diodes, minimising charging losses.\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.606 kg, with no moving parts and no maintenance requirements.\u003c\/li\u003e\n  \u003cli\u003ePassive operation: no control wiring, relays or external power supply required.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eDiode isolators work by allowing current to flow in one direction only. The Argodiode 80-2AC accepts a single input from an alternator or battery charger and splits it across two output terminals, each connected to a separate battery bank. Because diodes block reverse current, neither battery can discharge into the other, and a fault or deep discharge on one bank will not affect the other.\u003c\/p\u003e\n\n\u003cp\u003eThe Schottky diode design used in the Argodiode series produces a lower forward voltage drop than conventional silicon diodes. This is relevant in alternator-based systems because the voltage drop across the isolator effectively reduces the charging voltage seen by the batteries. In practice, the alternator output voltage should be set approximately 0.5V to 0.6V higher than normal to compensate. This adjustment is straightforward on vehicles or vessels where the alternator regulator is accessible.\u003c\/p\u003e\n\n\u003cp\u003eThe 80A rating covers the total input current. Both output banks share this capacity, so the installer should confirm that the combined load from both banks during charging does not exceed 80A. The unit requires no external control wiring and generates no switching noise, making it a reliable choice where simplicity and long service life are priorities.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSKU: ARG080201000\u003c\/li\u003e\n  \u003cli\u003eModel: Argodiode 80-2AC\u003c\/li\u003e\n  \u003cli\u003eMaximum continuous current: 80A\u003c\/li\u003e\n  \u003cli\u003eNumber of battery outputs: 2\u003c\/li\u003e\n  \u003cli\u003eDiode type: Schottky (AC configuration)\u003c\/li\u003e\n  \u003cli\u003eWeight: 0.606 kg\u003c\/li\u003e\n  \u003cli\u003eGTIN: 8719076018971\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 isolation between a starter battery and a domestic or service battery bank.\u003c\/li\u003e\n  \u003cli\u003eCampervans, motorhomes and HGVs where a vehicle starter battery must be kept separate from a leisure battery.\u003c\/li\u003e\n  \u003cli\u003eOff-grid systems with a single charger feeding two independent battery banks.\u003c\/li\u003e\n  \u003cli\u003eDual-battery setups in 4x4 vehicles and commercial vehicles where cross-discharge must be prevented.\u003c\/li\u003e\n  \u003cli\u003eAny application where a relay-based battery-to-battery charger is not required and passive isolation is sufficient.\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 80-2AC battery isolator\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eInstallation Notes\u003c\/h3\u003e\n\u003cp\u003eThe Argodiode 80-2AC should be installed by a qualified electrician or competent marine\/vehicle electrical engineer. Ensure the input cable and both output cables are correctly rated for the current involved and that appropriate fusing is fitted on each output. If the unit is fed from a vehicle alternator, the alternator regulator voltage should be increased by approximately 0.5V to 0.6V to compensate for the diode voltage drop and ensure the batteries receive a full charge. Mount the unit on a solid surface with adequate ventilation, as the heatsink will become warm under load. Do not enclose the unit in a sealed space without provision for heat dissipation.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":60201797779790,"sku":"ARG080201000","price":36.49,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/VoltaconSolar_-_ARG080201000_-_Argodiode_80-2AC_2_batteries_80A.webp?v=1784819034","url":"https:\/\/voltaconsolar.com\/products\/victron-argodiode-80-2ac-battery-isolator-80a","provider":"VoltaconSolar","version":"1.0","type":"link"}
