Mastervolt Battery Mate 200-Amp 3-Bank IG Isolator

Mastervolt Battery Mate IG Isolator (200 Amp, 3 Bank) is the ultimate solution for charging several batteries simultaneously, compatible with any type of alternator or battery charger in existing or new systems. It is designed for boaters who want negligible voltage loss between the alternator and battery for far better performance than conventional isolators.

Unlike conventional diode-splitter isolators, the Battery Mate uses electronic MOSFET technology that compensates for voltage variations, ensuring charging continues at the right level even across several battery banks. The input side connects to the alternator or battery charger, with batteries on the output side, and easy DIN rail installation. An additional IG contact can be connected for alternators needing external excitation or voltage sensing. Browse more options in our battery chargers category.

Key Features

• MOSFET electronic isolation compensates for voltage variations better than a standard diode isolator.
• DIN rail mount simplifies installation in an electrical panel enclosure.
• Compatible with any alternator or charger, so it's not locked to one brand.
• IG contact option lets you connect an alternator that needs external excitation or voltage sensing.
