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. It protects the starter battery from auxiliary loads, ensuring essential power is ready when you need it most.
-
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: 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.
-
Starter battery protection: Prevents discharge of the starter battery due to accessory loads, supporting 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.
-
180 A charging capacity: Built to handle the power needs of three batteries in parallel setups with a single alternator.
-
Versatile applications: Ideal for marine, RV, or off-grid use, reducing wiring complexity without compromising performance.
By isolating auxiliary loads from the starter battery while enabling multi-battery charging, the Argodiode 180-3AC helps ensure you have reliable power when you need it most. The low voltage drop improves charge delivery to each battery, and the energize input enhances starting reliability across varied installations.
