Victron Argo Diode Battery Isolators

Argo diode battery isolators allow multiple batteries to charge simultaneously from one alternator while still maintaining separate battery bank isolation. This protects fully charged battery banks from discharging to depleted batteries yet still allowing incoming charge current. This is achieved by diodes that function as a gate between the banks. Battery isolation is important in marine, RV and generator wiring plans, to prevent household/accessory battery banks from depleting the starter battery.

Argo battery isolators achieve minimal voltage loss by using super efficient Schottky diodes. This means higher voltage output to charge batteries as close as possible to 100%. The voltage drop is 0.3VDC at low current draw and only 0.45VDC at rated output. All models are further fitted with a compensation diode to slightly increase alternator output voltage.

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.

Note: All models with "AC" designation include the Alternator Engergize Input. ARG080202000 80-2"SC" model does not. All models feature compensation diode.
