Meet the Victron Argodiode Battery Isolator 180-3AC — a robust solution for multi-battery systems that lets you charge up to three batteries from a single alternator without cross-connecting them. Designed to prevent the starter battery from draining when auxiliary loads are in use, it keeps your essential power ready when you need it most.
Key benefits at a glance:
-
Three-battery charging from one alternator: Simultaneous charging of up to three batteries without wiring them together.
-
Low voltage drop: High-efficiency Schottky diodes yield approximately 0.3 V drop at light current and about 0.45 V at the rated output, maximizing charge delivered to each battery.
-
Compensation diode: Included to slightly boost alternator output, offsetting diode drop. Note that the overall charge voltage may be marginally reduced when installed.
-
Energize input for reliable start of charging: A current-limited energize input powers B+ when the engine run/stop switch is engaged, helping the alternator begin charging in a broader range of setups.
-
Protects battery longevity: By preventing discharge of the starter battery due to accessory loads, it supports healthier, longer-lasting batteries.
-
Easy installation: Simply insert the isolator between the alternator and the battery bank to enable multi-battery charging with minimal wiring complexity.
-
Durable and trusted: Manufactured by Victron Energy, model ARG180301020, designed for demanding marine, RV, or off-grid applications requiring reliable 180 A operation for three batteries.
This Argodiode isolator is optimized for multi-battery systems where staying charged matters. If you need assistance with returns, repairs, or support related to this product, please contact your Victron dealer for guidance.
