The REDARC Smart Start SBI24D 100 Amps dual battery isolator enables the user to charge a 24 volt start battery from a solar panel or battery charger on the auxiliary battery.

The REDARC Smart Start® SBI24D is a dual battery isolator used to isolate the start and auxiliary batteries in a dual battery system. It will protect the start battery from a low charge in the secondary battery so it won’t drain the primary battery. The SBI24D provides 24 volt DC incorporating 100A of continuous ratings.

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. The SBI24D also allows the start battery to be topped up and charged from the auxiliary battery when the auxiliary battery is being charged by an external source once it reaches 26.4 volts.

The Smart Start SBI24D is a microprocessor controlled battery isolator that incorporates electronic components preventing the solenoid from generating high voltage transients. It is better than a diode battery isolator due to the voltage drop associated with diode type isolation. It features sophisticated fault detection and LED indication of operation to warn the user of faults including over-voltage, voltage drop and excessive current draw conditions.
