   * Vpanel == Vmp((although [[electrical:solar:output|temperature derating]] will cause Vmp to drop))
   * Vbatt climbing toward Vabs
-  * Current delivered to battery holds steady((assuming sunlight holds steady))
+  * charge delivered to battery holds steady((assuming sunlight holds steady))  Note:  in a lab environment with DC power supplies the current (measured in Amps) could stay steady as the battery approaches Vabs.((the charger would get more and more wattage from the wall socket))  When charging off-grid we are typically limited by charging wattage, say 300w from the alternator or panels.  At 12.1v you would see ~25A charging (300w/12.v = 24.79A) but at 14v you'd only see ~21.5A (300w/14v = 21.43A)
   * **Example:**  Panel voltage at Vmp == 17v, battery voltage 12.9v and rising, controller output steady at 4A.
