A deep discharge of the battery can be prevented by connecting all loads to the load exit. The load exit separates the loads when the battery has been unloaded to a given voltage value. (48 V-model: interface to a relay) Alternatively, an algorithm for intelligent battery management can also be selected: see BatterLife. The load exit is short -circuit -proof. If the solar charging controller is unable to charge the battery within one day to its full capacity, the status of the battery constantly changes between "partially charged" and "end of discharge". This operating mode (no regular charging) damages a lead-acid battery within a few weeks or months. The battery algorithm monitors the charging status of the battery and, if necessary, it takes up the threshold to separate the load every.
