Victron Energy Argofet Battery Isolators 200-3AC (3 Batteries 200 Amp)This battery isolator enables you to charge three batteries simultaneously from a single alternator without physically connecting them together. It automatically detects whether your system operates at 12 volts or 24 volts, making it compatible with a wide range of vehicles and marine applications. Unlike traditional diode isolators, this FET-based unit maintains minimal voltage drop to ensure optimal charging efficiency.MPN
