    About this product

    Victron Argo FET Isolator 200-2 Two Batteries 200 A charges separate battery banks from one alternator while keeping the banks electrically separated from one another.

    FET technology produces a much smaller voltage drop than a conventional diode isolator, helping preserve charging voltage at the batteries. The energize input supports alternators that need voltage at their output connection before they start charging.

    Key features

    • Low-loss FET battery isolation
    • Separate outputs for the number of battery banks identified in the model name
    • Alternator energize input for compatible alternators

    Use adequately sized, short charging cables and follow the manufacturer's alternator-connection instructions.
