Victron Argodiode 80-2AC Battery Isolator Diode 80A for 2 Batteries

Victron Argodiode 80-2AC 2 batteries 80A

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 discharged without simultaneously discharging the starter battery. The use of modern Schottky diodes also keeps voltage loss 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 output voltage of the alternator to compensate for the voltage loss caused by the Schottky diodes.

Alternator starting excitation Some alternator types require DC voltage at the B+ terminal for starting 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 the alternator does not start. The new 802AC battery isolation diode has a special current-limited connection for starting excitation when the alternator is started.
