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 0.6V to 0.7V voltage drop associated with traditional diode-based isolators, ensuring batteries receive the full charge voltage.\u003c\/li\u003e\n  \u003cli\u003eCharges two independent battery banks from a single input source without cross-discharge between banks.\u003c\/li\u003e\n  \u003cli\u003eNegligible power loss compared to diode isolators, reducing heat generation and improving overall system efficiency.\u003c\/li\u003e\n  \u003cli\u003eCompact and robust aluminium housing suitable for installation in engine bays and confined spaces.\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard alternators and battery chargers without requiring modifications to the charging source.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eTraditional diode-based battery isolators introduce a voltage drop of around 0.6V to 0.7V between the charging source and the battery. In practice, this means batteries never receive the full charge voltage, leading to chronic undercharging over time. The Argofet 200-2 uses MOSFET technology to eliminate this drop, so the voltage at each battery terminal matches the output of the alternator or charger directly.\u003c\/p\u003e\n\n\u003cp\u003eThe isolator works by allowing current to flow freely from the input to each battery bank during charging, while blocking reverse current flow between the two banks. This means a discharged starter battery cannot drain the leisure or auxiliary bank, and vice versa. The 200A rating makes it appropriate for systems with high-output alternators or where multiple large batteries are being charged simultaneously.\u003c\/p\u003e\n\n\u003cp\u003eThe unit requires no external control wiring in most standard installations. It is a passive device that responds automatically to the presence of a charging voltage, making integration straightforward for experienced installers.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSKU: ARG200201020R\u003c\/li\u003e\n  \u003cli\u003eMaximum continuous current: 200A\u003c\/li\u003e\n  \u003cli\u003eNumber of battery outputs: 2\u003c\/li\u003e\n  \u003cli\u003eTechnology: FET (MOSFET) isolator\u003c\/li\u003e\n  \u003cli\u003eVoltage drop: Negligible (no diode drop)\u003c\/li\u003e\n  \u003cli\u003eWeight: 1.3 kg\u003c\/li\u003e\n  \u003cli\u003eGTIN: 8719076019145\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 domestic 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 bank.\u003c\/li\u003e\n  \u003cli\u003eOff-grid vehicles and 4x4 expedition builds with dual battery setups.\u003c\/li\u003e\n  \u003cli\u003eCommercial vehicles where auxiliary equipment batteries must be kept independent from the engine start battery.\u003c\/li\u003e\n  \u003cli\u003eAny system where a single alternator or charger must feed two battery banks without cross-discharge risk.\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 Argofet 200-2 FET battery isolator\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 experienced marine\/vehicle electrical installer. Ensure all connections are correctly rated for 200A continuous current and that appropriate fusing is fitted on the input cable as close to the source as practicable. The unit should be mounted in a ventilated location away from direct water ingress. Although the Argofet 200-2 produces significantly less heat than a diode isolator, adequate airflow around the unit is still recommended. Verify compatibility with your alternator output and battery chemistry before installation.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":59863664361806,"sku":"ARG200201020R","price":87.9,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/VoltaconSolar_-_ARG200201020R_-_Argofet_200-2_Two_batteries_200A_Retail.webp?v=1781183098","url":"https:\/\/voltaconsolar.com\/products\/victron-argofet-200-2-fet-battery-isolator-200a","provider":"VoltaconSolar","version":"1.0","type":"link"}
