====== Electrical terms ====== | ====== 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. |
* **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. | * **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]] |
