Victron Energy Argodiode Battery Isolators

Overview Argo Diode Battery Isolator (120-2AC) – Charge Multiple Batteries Without Draining Your Starter The Argo Battery Isolator allows you to safely charge multiple batteries from a single alternator while keeping them electrically isolated from each other. This means your starter battery stays protected. Running accessories from a secondary battery will not drain your ability to start your engine. This is especially important in RV, marine, and off-grid systems where multiple battery banks are used for different purposes. The 120-2AC model also solves a common issue with modern alternators. Some alternators require voltage on the output terminal (B+) to begin charging. Traditional isolators can block this, preventing the alternator from starting. The AC series includes a built-in energize input to ensure proper alternator startup, making it a reliable solution for a wider range of systems. Features Dual Battery IsolationAllows two batteries to be charged from a single alternator wh
