The Victron Energy Argodiode 100-3AC 100A battery isolator allows three 12V or 24V batteries to charge simultaneously from one alternator without electrically connecting the battery banks. Its high-efficiency Schottky diodes help prevent accessory batteries from discharging the starter battery while keeping voltage drop low.
Rated for 100A maximum charge and alternator current, it includes a compensation diode and alternator energize input for compatible charging systems. Installed between the alternator and batteries, it provides dependable three-bank isolation and efficient charging for vehicle and marine applications.
