X-SPLIT APPLICATION No.1

Application shows a single alternator with a 2 battery bank system using a XSP**/1/2BS, for systems with 3 or 4 battery banks use an XSP**/1/3 and XSP**/1/4 respectively (** denotes rating of X-SPLIT which = charging source capability, 60A, 90A, 120A ). This allows all three batteries to be charged simultaneously with ultra low loss from the alternator but prevents any battery discharging another when the charging source is not present. In other applications the Alternator can be replaced by another charging source, such as Wind Generator, Towed Generator, Solar Cell Array etc. Where there is a multi source charging capability (in addition to the normal alternator) such as a standby wind generator and or solar cell the additional charging sources can be paralleled to the input to enable all batteries to be charged simultaneously.
If the alternator is battery sensing then the extra circuits shown in dotted line must be used or a separate external energisation source used to ensure correct alternator charging. In some applications where a large auxiliary battery bank is used problems have occurred where the protection fuse is blown when the engine is initially started. If this problem proves to be a nuisance then the alternative installation in BLUE is recommended. If there is a spare contact on the ignition switch it is also possible to use an energisation feed obtained directly from the auxiliary battery. For applications requiring the use of an alternator charge controller in conjunction with the X-SPLIT look at the application notes associated with the X-ALT.
