Victron Argo Diode 80-2AC 80A Battery isolator

The Victron Argo 80-2AC battery isolator (MPN ARG080201000R) allows the current distribution out of one energy source (e.g. alternator) to multiple battery circuits.

With help of these isolators 2 or 3 separate battery circuits can be charged with only one power source. These batteries do not need to be connected which makes installation easier and reduces costs.

Features:

• latest Schottky-diodes (hot-carrier-diodes) to keep voltage-loss at a minimum.
• equipped with current-limiting connector for alternator energize input (generators, alternator,...)
• Argo 80-2AC provides a max. charging current of 80A and supports 2 batteries or battery banks
• alternator max. current 80A - supply battery can be used without discharging the starter battery

Minimum voltage loss thanks to latest Schottky-diodes (hot-carrier-diodes)
Thanks to latest Schottky-diodes voltage loss is reduced to a minimum - 0.3V at low currents and 0.45V at nominal current.
All models out of Victron's Argo-series are equipped with a compensation-diode which slightly increases the alternator's output voltage and therefore compensates the voltage loss caused by the Schottky-diodes.
This is important because if the isolator is integrated into the cabling between battery and alternator without any compensation a voltage loss occurs that leads to incomplete charging and early battery aging.

Current-limiting alternator connector
Some kinds of generators need DC-voltage on their B+-pole as energize input. On one hand there is a direct connection of battery and generator, on the other hand the isolator prevents a current reflow that keeps the generator from starting.
Arco-diodes (80-2AC or bigger) are equipped with a special alternator connector that allows an energize input when the generator is started. That ensures a smooth current flow between generator and battery.
