## Summary description

The Victron Energy Argo FET 200-3 is a high-efficiency battery isolator designed to charge three separate battery banks simultaneously from a single alternator or battery charger. Utilizing MOSFET technology, it minimizes voltage drop to less than 0.02V at low current and 0.1V at high current, ensuring efficient charging without the need for voltage compensation. Ideal for marine and automotive power systems requiring reliable battery management.

## Long description

The Victron Energy Argo FET 200-3 is a high-performance battery isolator engineered to manage the charging of three independent battery banks from a single power source, such as an alternator or battery charger. By utilizing advanced MOSFET technology, this device effectively replaces traditional diode-based isolators, providing a significantly more efficient power distribution solution for marine and automotive electrical systems.
Advantages
The primary benefit of the Argo FET 200-3 is its exceptional efficiency. Unlike conventional diode isolators that cause significant voltage drops, the MOSFET design ensures a voltage drop of less than 0.02V at low currents and only 0.1V at higher currents. This eliminates the need to adjust the alternator output voltage, ensuring that batteries are charged quickly and fully. Furthermore, the unit is built with a robust, durable housing designed to withstand the demanding conditions of mobile and marine environments, providing long-term reliability for complex power setups.
Suitable for
Marine power systems with multiple battery banks
Automotive and campervan auxiliary battery management
Off-grid solar power installations requiring multi-bank charging
Industrial equipment with secondary battery backup systems
When it may not be suitable
This battery isolator is not intended for systems where the total charging current exceeds 200A, as this would exceed the device's thermal and electrical capacity. Additionally, it is not a substitute for a battery combiner or a DC-DC charger in systems where the alternator voltage is incompatible with the chemistry of the auxiliary batteries.
Key specifications
Maximum charging current: 200A
Number of battery banks: 3
Voltage range: 12V and 24V compatible
Voltage drop: Less than 0.02V at low current, 0.1V at high current
Technology: MOSFET
How to use
Installation involves connecting the main charging source, such as the alternator output, to the input terminal of the Argo FET. The three output terminals are then connected to the positive terminals of each individual battery bank. The device operates automatically, sensing the presence of a charging voltage and distributing current to the batteries as needed without requiring manual intervention or complex switching.
What to consider before purchase
Ensure your alternator output does not exceed the 200A rating of the isolator.
Verify that your battery banks are of compatible voltage (12V or 24V).
Check that your wiring gauge is sufficient to handle the 200A current load safely.
Usage recommendations
For optimal performance and safety, always install a fuse on the output side of each battery connection to protect against short circuits, and ensure the unit is mounted in a well-ventilated area to allow for proper heat dissipation during high-current operation.
