-====== Electrical ​notation ​======+====== Electrical ​terms often seen with solar ======
  
  
   * **I** - current in Amps.  The //I// comes from the archaic term //​intensity//​.   * **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.   * **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.  Vmp * Imp = Pmax
 +  * **[[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   * **V** - Volts
   * **Vabs** - [[electrical:​solar:​charge_controller|charge controller]] voltage setpoint for [[electrical:​12v:​charging#​absorption_stage|Absorption stage]]   * **Vabs** - [[electrical:​solar:​charge_controller|charge controller]] voltage setpoint for [[electrical:​12v:​charging#​absorption_stage|Absorption stage]]
 +  * Vbatt - actual voltage of the battery bank.
   * **Vfloat** - charge controller voltage setpoint for [[electrical:​12v:​charging#​float_stage|Float stage]]   * **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.   * **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   * **W** - power in Watts
