Symbol Significance Remarks
P+ Value of the active power +
Positive parameter
(user)
Pfc+ Capacitive power factor +
Pfi+ Inductive power factor +
Qc+ Value of the capacitive reactive power +
Qi+ Value of the inductive reactive power +
P- Value of the active power -
Negative parameter
(generator)
Pfc- Capacitive power factor -
Pfi- Inductive power factor -
Qc- Value of the capacitive reactive power -
Qi- Value of the inductive reactive power -
Value Significance
P The active power (positive or negative) is defined in the panel and therefore acquires
the value of the active power in that moment
Q The reactive power (inductive or capacitive, positive or negative) is defined in the
panel and therefore acquires the value of the reactive power in that moment
Pf The power factor (inductive or capacitive, positive or negative) is defined in the panel
and therefore acquires the value of the power factor in that moment
0 The active power (positive or negative) or the reactive power (inductive or capacitive,
positive or negative) is NOT defined in the panel and therefore acquires a null value
-1 The power factor (inductive or capacitive, positive or negative) is NOT defined in the
panel
