The Dual Sensing Smart Battery Isolator monitors both the starting battery and the auxiliary. If the unit detects that either battery has exceeded 13.2 volts, then the isolator will connect them. The benefit of the dual sensing feature is the ability for a user to charge the main battery from a solar panel or an external battery charger on the auxiliary battery, once the auxiliary battery reaches 80% state of charge (13.2V). This ensures you never have a drained starter battery again. The isolator is also automatic and is based on voltage, which saves installation time. When the entire battery system drops below 12.7 volts the solenoid opens and isolates the starter battery from the auxiliary battery.
