You can use the SmartStart® to switch an auxiliary load (e.g. The SmartStart® will not be affected by not having an auxiliary battery connected.Ĭan I use the SmartStart® to control a load (e.g., fridge) without using an auxiliary battery? This input may be temporarily connected to +12V from the auxiliary battery to turn the solenoid on.Ĭan I leave the SmartStart® connected if a trailer or caravan is not hooked up to the towing vehicle? The Redarc SmartStart® has an additional input (blue wire) which can be used to override the voltage sensing feature for emergency starting. Many users owning current model 4WDs have bought and used the SmartStart® with the product working exactly as designed.Ĭan an override switch be fitted to the dash to allow the auxiliary battery to be joined to the start battery to assist with starting? Is the Redarc SmartStart® suitable for use on modern vehicles fitted with the latest alternators using smart electronics? Call Redarc for further information on what customisation is The unit incorporates components which prevent the solenoid from generating high voltage transients.Īre the voltage limits and time delay settings customisable? Many users successfully operate their battery system with a standard cranking battery as main and a deep cycle battery as auxiliary.ĭoes the unit have surge or spike protection? The SmartStart® can be used with dissimilar battery types. The SmartStart® is ideal for installations that cannot tolerate the voltage drop associated with diode battery isolators. The SmartStart® features sophisticated fault detection and indication to warn the user of faults including overvoltage, voltage drop and excessive current draw conditions. When the system voltage drops below 12.7V the solenoid opens isolating the start battery from the auxiliary battery. The SmartStart® monitors the start battery voltage and when the start battery reaches 13.2V the SmartStart® connects the auxiliary battery to the charging system. Cost-effective protection against a flat battery.The Maximum inrush load rating for this model is 400 amp. The SBI12 model isolator has a voltage range of 9-15v and offers a 100 amp continuous load rating. The Redarc SmartStart ® is Australia’s most trusted dual battery isolator and is used by 4WD clubs throughout Australia. The Redarc SmartStart ® is designed primarily for use in 4WD and commercial vehicles. The Redarc SmartStart ® is a microprocessor-controlled battery isolator designed for use in multi-battery applications as a solenoid priority system, protecting the start battery from excessive discharge, whilst allowing the auxiliary battery to supply non-essential loads. Note: Do not connect gel-cell batteries to a vehicle's alternator.REDARC SmartStart® Dual Battery Isolator SBI12 12v 100A The cable for the override should be fused separately. Isolators with override function also require an additional switch - a momentary push button switch is recommended. Connect your auxiliary loads to the auxiliary battery (don't forget suitable fuse). Installation of a battery isolator is fairly simple as it does not interfere with existing wiring. a winch).īattery isolators may also have an application in stationary solar power systems for emergency lights or pumps, refrigeration for medical supplies or similar.īattery isolators only work with battery banks of the same voltage. Some battery isolators also have an override function which allows both batteries to be used for certain high powered appliances (e.g. Usually, if a single battery in a battery bank fails, the damaged battery discharges (or worse damages) the entire lot. Properly isolated batteries are also protected from discharge should the partnered battery fail. it ensures that the starter battery (or primary battery) of the vehicle remains full enough to start the engine by isolating it from the auxiliary (or secondary) battery.it recharges both batteries (or battery banks) by splitting the charge current into multiple branches without the need to wire the batteries in parallel, and.Battery Isolators are ideal for dual battery systems commonly found in recreational vehicles, boats, large trucks or motor homes.
