It is suited to marine, vehicle and off-grid applications where independent battery banks must be kept isolated from one another while sharing a common charge source.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eCharges three independent battery banks from a single input, with full isolation between banks so a fault or discharge on one bank cannot affect the others.\u003c\/li\u003e\n  \u003cli\u003eFET (Field Effect Transistor) technology eliminates the 0.6V to 0.7V voltage drop associated with conventional diode isolators, ensuring batteries receive the full charge voltage.\u003c\/li\u003e\n  \u003cli\u003e200A continuous current rating handles high-capacity alternators and multi-bank systems without derating.\u003c\/li\u003e\n  \u003cli\u003eAutomatic alternator voltage sensing allows the unit to compensate the alternator output voltage, maintaining correct charge levels across all banks.\u003c\/li\u003e\n  \u003cli\u003eCompact, aluminium construction with integrated heat sink for passive cooling, requiring no fan or active thermal management.\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard 12V and 24V systems, making it suitable for a wide range of vehicles, vessels and off-grid installations.\u003c\/li\u003e\n  \u003cli\u003eWeight: 1.37 kg, making it straightforward to mount in engine bays, battery compartments or distribution panels.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eConventional diode-based battery isolators introduce a voltage drop of around 0.6V to 0.7V on every charge path. Over a long charge cycle, this means batteries never reach their full charge voltage, which shortens battery life and reduces usable capacity. The Argofet 200-3 uses MOSFET switching to eliminate this drop entirely, so each battery bank receives the same voltage the alternator or charger is producing.\u003c\/p\u003e\n\n\u003cp\u003eThe unit supports three output banks at up to 200A total input current. Each output is fully isolated from the others: if one bank develops a fault or is deeply discharged, it cannot pull down the voltage on the remaining banks. This is particularly important in marine and commercial vehicle applications where a starter battery must remain protected from auxiliary or domestic loads.\u003c\/p\u003e\n\n\u003cp\u003eThe Argofet 200-3 includes an alternator voltage sense connection. When connected, this allows the alternator's internal regulator to see the actual battery voltage rather than the voltage at the alternator terminal, correcting for any cable resistance and ensuring the regulator does not under-charge the batteries. This feature is especially relevant when long cable runs are involved.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSKU: ARG200301020\u003c\/li\u003e\n  \u003cli\u003eInput current rating: 200A\u003c\/li\u003e\n  \u003cli\u003eNumber of battery outputs: 3\u003c\/li\u003e\n  \u003cli\u003eTechnology: MOSFET FET isolator\u003c\/li\u003e\n  \u003cli\u003eVoltage drop: Near zero (FET-based)\u003c\/li\u003e\n  \u003cli\u003eWeight: 1.37 kg\u003c\/li\u003e\n  \u003cli\u003eGTIN: 8719076019152\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 separate starter, domestic and bow-thruster battery banks charged from a single alternator.\u003c\/li\u003e\n  \u003cli\u003eHGVs, coaches and commercial vehicles with multiple auxiliary battery banks alongside a starter battery.\u003c\/li\u003e\n  \u003cli\u003eMotorhomes and campervans where a leisure battery bank must be isolated from the vehicle starter battery.\u003c\/li\u003e\n  \u003cli\u003eOff-grid installations with a single charge source feeding separate battery banks for different loads.\u003c\/li\u003e\n  \u003cli\u003eEmergency and specialist vehicles requiring guaranteed starter battery isolation from auxiliary systems.\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 200-3 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 marine electrical engineer familiar with high-current DC systems. The unit must be mounted in a well-ventilated location and secured to a surface capable of supporting its weight and the mechanical load of heavy cable connections. Ensure all cable sizing is appropriate for 200A continuous current and that suitable fusing is fitted on the input and each output. For alternator voltage sensing, connect the sense wire directly to the alternator's sense terminal as described in the Victron wiring documentation. Do not install in enclosed spaces without adequate airflow around the heat sink.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":59863664591182,"sku":"ARG200301020","price":102.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/VoltaconSolar_-_ARG200301020_-_Argofet_200-3_Three_batteries_200A.webp?v=1781183102","url":"https:\/\/voltaconsolar.com\/products\/victron-argofet-200-3-fet-battery-isolator-3-banks-200a","provider":"VoltaconSolar","version":"1.0","type":"link"}
