* Discharge reconnect meaning. This voltage is user adjustable. As the load consumes the power within the battery, the voltage eventually drops to 10.7V and the load output of the controller will automatically stop any further charge from protect the battery. If for example the next day maybe rainy or cloudy day and the battery charges slowly, if the voltage is still below 12.6V, the load output from the controller will still not work. If the sun comes out in the afternoon, or the next day is much sunnier conditions, once the battery voltage rises above 12.6V, the controller load output will automatically start to work again. Discharge reconnect is set to 12.6V by default, although you may wish to set this perhaps 12.4V. Discharge reconnect is aimed at protecting the battery and reducing the depth of discharge cycling. Lead acid batteries last longer with shallow discharge.
