Redarc Smart Battery Isolator 100A

The Smart Start SBI is a microprocessor controlled Smart Battery Isolator.
The Smart Start SBI is designed specifically for use in multi battery applications as a solenoid
priority system to protect the start battery from being excessively discharged by auxiliary loads,
whilst still allowing the auxiliary battery to supply non essential loads. Put simply, once the start
battery is charged by the alternator, the Smart Start SBI will connect an auxiliary battery to the
charge circuit. Similarly, if the start battery voltage drops too low, the Smart Start SBI will
disconnect any auxiliary batteries or loads to conserve charge in the start battery.

Dual Sensing

The dual sensing model is used to isolate the start and auxiliary batteries in a system where the auxiliary battery may also be charged by an external source such as Solar panels or an external AC battery charger. Dual Sensing models also allow the start battery to be charged by the external source once the auxiliary battery reaches 13.2 volts. This is useful to top up the start battery.
