   * **12.2v** at daybreak, approximately 50% [[electrical:depth_of_discharge|Depth of Discharge]].  Charging is in the Bulk stage and **all three sources are contributing**; the battery bank voltage is lower than what they all want to provide.  The alternator is contributing the most because it can produce the most current and the panels aren't getting much light yet.    * **12.2v** at daybreak, approximately 50% [[electrical:depth_of_discharge|Depth of Discharge]].  Charging is in the Bulk stage and **all three sources are contributing**; the battery bank voltage is lower than what they all want to provide.  The alternator is contributing the most because it can produce the most current and the panels aren't getting much light yet.

   * **14.1v** by the you get to a neighboring town.  **Alternator charging ceased at 14.0v**; it has plenty of current but no voltage "pressure" to force that current into the battery.  Your battery bank is now being charging only by solar (the two separate controllers).   * **14.1v** by the you get to a neighboring town.  **Alternator charging ceased at 14.0v**; it has plenty of current but no voltage "pressure" to force that current into the battery.  Your battery bank is now being charging only by solar (the two separate controllers).
