That ensures a smooth current flow between generator and battery. 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.Īrco-diodes (80-2AC or bigger) are equipped with a special alternator connector that allows an energize input when the generator is started. Some kinds of generators need DC-voltage on their B+-pole as energize input. 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. Thanks to latest Schottky-diodes voltage loss is reduced to a minimum - 0.3V at low currents and 0.45V at nominal current.Īll 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. Minimum voltage loss thanks to latest Schottky-diodes (hot-carrier-diodes) They make bigger capacity, but usually only 2 bank. The model number usually indicates the maximum amperage of the alternator input. current 100A - supply battery can be used without discharging the starter battery Battery Isolators are usually one or two inputs (alternators) and 2-4 outputs (battery banks). charging current of 100A and supports 3 batteries or battery banks equipped with current-limiting connector for alternator energize input (generators, alternator.).
With help of these isolators 2 or 3 separate battery circuits can be charged with only one power source. alternator) to multiple battery circuits. The Victron Argo 100-3AC battery isolator (MPN ARG100301000R) allows the current distribution out of one energy source (e.g.
