Victron Energy Argodiode Battery Isolator 80-2SC 2 Batteries 80A ARG080202000 (R)

Victron Energy Argodiode Battery Isolator 80-2SC 2 Batteries 80A ARG080202000 (R) Description

Diode battery isolators allow simultaneous charging of two or more batteries from one alternator, without
connecting the batteries together. Discharging the accessory battery for example will not result in also
discharging the starter battery.

The Argo Battery Isolators feature a low voltage drop thanks to the use of Schottky diodes: at low current the
voltage drop is approximately 0,3 V and at the rated output approximately 0,45 V.

It is fitted with a compensation diode that can be used to slightly increase the output voltage of the
alternator. This compensates for the voltage drop over the diodes in the isolator.

Installation should be conducted by a professional as simply inserting the isolator in the cabling between the alternator and the batteries will slightly reduce charge voltage. The result can be that batteries are not charged to the full 100% and age prematurely.

Alternator energize input
Some alternators need DC voltage on the B+ output to start charging. Obviously, DC will be present when the alternator is directly connected to a battery. Inserting a Diode or FET splitter will however prevent any return voltage/current from the batteries to the B+, and the alternator will not start.

The new ‘AC' diode isolators feature a special current limited energize input that will power the B+ when the engine run/stop switch is closed.
