It is suited to marine, vehicle and off-grid applications where independent battery banks must be kept isolated from one another during discharge while still being charged from a common source.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e200A continuous current rating supports high-capacity alternators and charging systems.\u003c\/li\u003e\n  \u003cli\u003eFET (Field Effect Transistor) technology eliminates the typical 0.6V to 0.7V voltage drop of diode-based isolators, allowing the full alternator or charger voltage to reach each battery bank.\u003c\/li\u003e\n  \u003cli\u003eTwo output channels allow simultaneous, isolated charging of two independent battery banks from one input source.\u003c\/li\u003e\n  \u003cli\u003eAutomatic operation with no manual switching required during normal use.\u003c\/li\u003e\n  \u003cli\u003eCompact and robust aluminium housing suitable for engine bay and marine installations.\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard alternators and external battery chargers as the input source.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eConventional diode isolators introduce a voltage drop of around 0.6V to 0.7V between the alternator and the battery. In practice, this means batteries receive a lower charge voltage than the alternator or regulator is set to deliver, which can result in chronic undercharging. The Argofet 200-2 uses MOSFET technology to reduce this drop to near zero, so each battery bank receives the full output voltage of the charging source.\u003c\/p\u003e\n\n\u003cp\u003eThe isolator works by allowing current to flow from the input to both output banks during charging, while preventing current from flowing between the two battery banks. This means a starter battery and a leisure or service battery can be charged together without the risk of the service bank draining the starter bank when the engine is off. The 200A rating makes it suitable for larger installations with high-output alternators or multiple chargers feeding into the system.\u003c\/p\u003e\n\n\u003cp\u003eThe unit requires no active control during normal operation. An alternator excitation connection is provided to ensure the MOSFET switches correctly when the alternator is running. Installers should verify that the alternator's voltage regulator is set appropriately, as the near-zero voltage drop means the regulator sees a more accurate battery voltage than it would with a diode isolator.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSKU: ARG200201020\u003c\/li\u003e\n  \u003cli\u003eInput channels: 1\u003c\/li\u003e\n  \u003cli\u003eOutput channels: 2 (two battery banks)\u003c\/li\u003e\n  \u003cli\u003eMaximum continuous current: 200A\u003c\/li\u003e\n  \u003cli\u003eTechnology: FET (MOSFET) isolator\u003c\/li\u003e\n  \u003cli\u003eWeight: 1.3 kg\u003c\/li\u003e\n  \u003cli\u003eGTIN: 8719076019138\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eMarine vessels with separate starter and service battery banks charged from a single alternator.\u003c\/li\u003e\n  \u003cli\u003eMotorhomes and campervans requiring isolation between the vehicle starter battery and the habitation battery bank.\u003c\/li\u003e\n  \u003cli\u003eTrucks and commercial vehicles with auxiliary battery systems.\u003c\/li\u003e\n  \u003cli\u003eOff-grid installations where a single charger must feed two independent battery banks.\u003c\/li\u003e\n  \u003cli\u003eAny dual-battery system where voltage drop from a diode isolator is causing undercharging issues.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eWhat Is Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eVictron Argofet 200-2 FET battery isolator unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eInstallation Notes\u003c\/h3\u003e\n\u003cp\u003eInstallation should be carried out by a qualified electrician or marine electrical engineer familiar with high-current DC systems. The unit must be mounted in a ventilated location as it will generate heat under load. Ensure all cabling is rated for 200A continuous use and that appropriate fusing is fitted on the input and output connections. The alternator excitation wire must be connected correctly for the MOSFET to operate. Do not install in sealed or unventilated enclosures.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":59863664329038,"sku":"ARG200201020","price":87.9,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/VoltaconSolar_-_ARG200201020_-_Argofet_200-2_Two_batteries_200A.webp?v=1781183094","url":"https:\/\/voltaconsolar.com\/products\/victron-argofet-200-2-battery-isolator-two-banks","provider":"VoltaconSolar","version":"1.0","type":"link"}
