Victron Argodiode Battery Isolator 80-2AC - 2 Batteries - 80A

The Argodiode Battery Isolator 80-2AC is an essential component for marine and boating enthusiasts, enabling reliable and efficient management of multiple battery systems on your vessel. Designed to allow simultaneous charging of two batteries from a single alternator, this isolator ensures that your starter and accessory batteries operate independently, enhancing the overall electrical system's performance and longevity.

Key Features

Simultaneous Charging of Multiple Batteries

The Argodiode Battery Isolator 80-2AC allows you to charge two or more batteries simultaneously from one alternator without directly connecting them. This means that discharging the accessory battery, such as for running marine electronics, will not affect the starter battery, ensuring your engine remains ready to start when needed.

High-Efficiency Schottky Diodes

Equipped with high-efficiency Schottky diodes, the isolator minimizes energy loss during the charging process. This results in a lower voltage drop, enhancing the overall efficiency of your boat’s electrical system.

Low Voltage Drop for Optimal Charging

• At low current, the voltage drop is approximately 0.3 V.
• At the rated output, the voltage drop is approximately 0.45 V.

These low voltage drops ensure that your batteries receive maximum charge, promoting longer battery life and reliable performance during your maritime adventures.

Compensation Diode for Enhanced Alternator Performance

All models include a compensation diode that slightly increases the alternator's output voltage. This compensates for the voltage drop across the isolator’s diodes, ensuring that your batteries are charged effectively without compromising the alternator’s performance.

Advanced Alternator Energize Input

Some marine alternators require DC voltage on the B+ output to initiate charging. Traditional diode or FET splitters can prevent this necessary voltage, causing the alternator to fail to start charging. The Argodiode 80-2AC features a special current-limited energize input that provides the required B+ voltage when the engine's run/stop switch is engaged, ensuring seamless alternator operation.

Installation Considerations

Installing the Argodiode Battery Isolator is straightforward—simply insert the isolator into the cabling between the alternator and your batteries. However, be aware that this may slightly reduce the charge voltage. While this design conserves energy and prevents battery drain, it might result in batteries not reaching a full 100% charge, potentially leading to premature aging if not monitored regularly.
