   * the controller may get warmer as current demand drops((percentage of time the PWM circuit is turned OFF increases))
   * **Example:**  Panel and battery voltage held at Vabs == 14.6v, controller output 2A and dropping
+==== transitioning to float ====
+When transitioning from Absorption to Float the voltage needs to drop about a volt.  The system will "free-fall" (make little or no power) to allow the voltage to fall.  The transition may take seconds or minutes, depending on how/if the system is loaded.
+  * starts at Vabs
+  * power generation stops
+  * voltage drops to Vfloat
+  * when voltage reaches Vfloat the system will start making power to hold that setpoint.
