Otherwise, they are isolated, and discharge between banks is prevented.\u003cbr\u003e \u003cbr\u003e The traditional rugged and reliable diode isolator can also be used for this function, as it also maintains isolation between banks and allows charging from multiple sources. However, one drawback is inefficiency when voltage is lost as current passes through the diodes, resulting in undercharge if the charging source does not compensate for the voltage drop. \u003cbr\u003e \u003cbr\u003e The Battery Integrator remedies this by use of an extremely low resistance contactor which causes no voltage drop in the charging system, while the multiple batteries are charged as a single bank whenever a charging source of approximately 13.2 VDC or 26.4 VDC or greater is present (depending on model).\u003cbr\u003e \u003cbr\u003e When the alternator or charger is off or a large load causes the voltage to drop below the disconnect point the unit breaks the common tie between the banks. This allows selective battery discharge and prevents \"dumping\" of a higher-charged bank into a lower-charged bank.\u003cbr\u003e \u003cbr\u003e The unit may also be activated through the key starter or a manual switch to provide an added \"boost\" from the secondary battery whenever the starter is engaged and the unit senses there is sufficient voltage in that battery to provide an assist.\u003cbr\u003e \u003cbr\u003e For systems with more than two banks, an additional unit may be installed for each additional bank to provide the same isolation and integration as described above.\u003cbr\u003e \u003cbr\u003e The Battery Integrator is ideal for multiplying the single charging output of an inverter-charger to maintain both the house bank and an engine start bank, then to isolate them during inverter function, so current is drawn from the house bank only. \u003cbr\u003e \u003cbr\u003e Features\u003c\/p\u003e \u003cul\u003e \u003cli\u003eEnables charging of two separate banks without voltage drop, yet maintains 100% isolation at all other times.
