-This page is to help solar beginners tell what their system is doing without special equipment.  The info here is oriented to typical 12v systems with lead-acid battery banks.  Folks running other battery chemistries or nominal voltages are assumed to already know what they're doing.  :-)

 **with PWM controllers**
-  * Vpanel & Vbattery == Vabs until the controller's criteria for ending absorption is met
+  * Vpanel starts to creep up from Vbatt toward Voc (the more OFF switching the closer to Voc) criteria for ending absorption is met
   * Controller output decreasing as current demand drops.
   * the controller may get warmer as current demand drops((percentage of time the PWM circuit is turned OFF increases))
