ARCO Marine Battery Isolator for 10-350A Alternators

This robust battery isolator is designed specifically for 10 to 350-amp alternators operating on 12, 24, or 32-volt negative ground systems. It efficiently connects two alternators to three batteries, ensuring maximum performance and safety for your marine electrical system.

Key Features:

• Supports 2 alternators and 3 batteries with a maximum of 70A
• Allows electrical current to flow in one direction, preventing back discharge between batteries
• Automatically charges both batteries proportionally based on their needs while the engine runs
• No need to adjust selector switches for charging both batteries
• Proportionately distributes charging current from the alternator to the batteries
• Note: Not compatible with 12V systems using 24V trolling motors or newer outboard engines with rectifier-regulator systems
