-====== Electrical notation ======
+====== Electrical terms often seen with solar ======
   * **I** - current in Amps.  The //I// comes from the archaic term //intensity//.
+  * **Imp** current at the panel's maximum power output (see Vmp)
   * **Isc** - Amps when short circuited;  this is when your [[electrical:solar:panels|solar panels]] are connected only to themselves.  This is the highest current your panels can theoretically produce.
+  * **Pmax** maximum power a panel will make.
+  * **[[electrical:solar:charge_controller_setpoints|Setpoint]]** - a value used to place a limit or border on a particular operation.  If your refrigerator is set hold 40F temperatures then //40F is the setpoint//.  If your charger floats at 13.2v then //13.2v is the Vfloat setpoint//.  Setpoints may be preset by the manufacturer or configured by the user.
   * **V** - Volts
-  * **Vabs** - charge controller voltage setpoint for Absorption stage
+  * **Vabs** - [[electrical:solar:charge_controller|charge controller]] voltage setpoint for [[electrical:12v:charging#absorption_stage|Absorption stage]]
-  * **Vfloat** - charge controller voltage setpoint for Float stage
+  * Vbatt - actual voltage of the battery bank.
+  * **Vfloat** - charge controller voltage setpoint for [[electrical:12v:charging#float_stage|Float stage]]
+  * **Vmp** - voltage at which a panel makes **m**axiumum **p**ower (watts)
   * **Voc** - volts in open circuit; when your [[electrical:solar:panels|solar panels]] are not connected to anything.  This is the highest voltage your panels can theoretically produce.
+  * **Vpanel** - voltage the controller is running the panel[s] at
   * **W** - power in Watts
