 For solar powered systems the greatest DoD (and therefore lowest SoC) will be in early morning just before the panels start creating power again. For solar powered systems the greatest DoD (and therefore lowest SoC) will be in early morning just before the panels start creating power again.

 +100% SoC (~12.7v) is measured [[electrical:12v:charging|after the bank has been fully charged]] and then rested. It is measured "on the way down";  measuring "on the way up" while charging will lead to false confidence and leaving the battery [[electrical:12v:psoc|less than fully charged]].
  
 The voltage level associated with 50% DoD is widely discussed.  **12.1v rested** is generally used as 50% State of Charge (SoC).  A more conservative approach uses **12.2vdc rested**. The voltage level associated with 50% DoD is widely discussed.  **12.1v rested** is generally used as 50% State of Charge (SoC).  A more conservative approach uses **12.2vdc rested**.
