Victron Argodiode 160-2AC Battery Isolator Diode 160A for 2 Batteries

Victron Argodiode 160-2AC 2 batteries 160A

Battery isolation diodes allow multiple batteries to be charged simultaneously from a single power source without the individual batteries being connected to each other. This means, for example, that the house battery can be powered without simultaneously discharging the starter battery. The use of modern Schottky diodes also keeps voltage drop to a minimum. It is approx. 0.3 V at low currents and approx. 0.45 V at rated current.

All models in this series are equipped with a compensation diode that slightly increases the alternator output voltage to compensate for the voltage drop caused by the Schottky diodes.

Alternator start-up excitation Some alternator types require DC voltage at the B+ terminal for start-up excitation. On the one hand, there is a direct cable connection between the battery and the alternator. On the other hand, however, the isolation diode prevents current from flowing back, so that the alternator does not start. The new 802AC battery isolation diode has a special current-limited connection for start-up excitation when the alternator is started.
