The REDARC Smart Start SBI224 200A is a 24V DC 200 Amps microprocessor-controlled, dual battery isolator designed to protect the start battery from excessive discharge while allowing the auxiliary battery to supply charge to non-essential loads.

The REDARC Smart Start® SBI224 is used in dual battery systems to protect the start battery from excessive discharge while the auxiliary battery is supplying non-essential loads. The SBI224 provides 24 volt DC incorporating 200A of continuous ratings. The 200A battery isolator is best suited for heavy-duty operations.

The Smart Start SBI224 battery isolator is mostly used in commercial vehicle dual battery systems, it incorporates electronic components preventing the solenoid from generating high voltage transients. Used instead of a diode battery isolator due to reduce 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.
