This system eliminates the possibility of draining the start battery and protects sensitive electronic equipment powered from the house battery from harmful engine start up spikes. When the voltage drops below 12.9 volts (eg the engine is stopped), the relay disengages, separating the batteries. When the engine is started and either battery reaches 13.4 volts, the relay engages, allowing two battery banks (start and accessory) to be charged simultaneously. How it works: The smart isolator allows two batteries to be charged at the same time. If placed in linear sequence between each battery the isolator units can provide proper charging for several batteries in a multiple battery setup such as in larger boats that may have 2 or more house batteries. This prevents problems that may result from your charging source being too low in amps to charge all batteries as once. The advanced technology always insures that the first battery is fully charged (13.4v) before connection is made to the second battery. a battery charger is connected to the auxiliary battery the relay will engage and charge both batteries. If either battery is receiving a charge, e.g. The smart isolator is also “Dual Sensing” which senses the charge of both batteries. The small size and rugged construction of these units allow for quick simple installation for even the most novice DIYer. These units can be installed between batteries with a common ground to automatically control the charging process to the batteries but continue to provide isolation when a charging source is unavailable.
