Victron Energy Argofet Battery Isolators 100-3AC (3 Batteries 100 amp)
Victron Energy Argofet battery isolators 100-3AC, allow simultaneous charging of three batteries from one alternator, without connecting the batteries together. 1224 Volt auto ranging Victron Energy Argofet battery isolator will automatically adjust to a 12-Volt or 24-Volt system. In contrast with diode battery isolators, FET isolators have virtually no voltage loss. Voltage drop is less than 0.02-Volt at low current and averages 0.1-Volt at higher currents. Discharging the accessory battery for example will not result in also discharging the starter battery. When using Victron Energy ARGO FET Battery Isolators, there is no need to also increase the output voltage of the alternator. However, care should be taken to keep cable lengths short and of sufficient cross section.
Victron Energy ArgoDiode Battery Isolators 160-2AC (2 Batteries 160 amp)
Victron Energy ArgoDiode battery isolators 160-2AC allow simultaneous charging of two batteries from one alternator. Alternator energize input Victron Energy new AC diode isolators feature a special current limited energize input that will power the B when the engine runstop switch is closed. 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. Victron Energy Argo Battery Isolators feature a low voltage drop thanks to the use of Schottky diodes. All models are 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.
