The PF is fixed at +1.000.
PF
The reactive power can be regulated by the parameter PF (Power
Factor).
Qt
The reactive power can be regulated by the parameter Q-Var limits (in
%).
Q(P)
The PF changes with the output power of the inverter.
Q(U)
The reactive power changes with the grid voltage.

The power factor is fixed and reactive power setpoint is calculated according to the cur-
rent power. The PF ranges from 0.8 leading to 0.8 lagging.
Leading: the inverter is sourcing reactive power to the grid.
Lagging: the inverter is injecting reactive power into the grid.

In the Qt mode, system rated reactive power is fixed, and the system injects reactive
power according to the delivered reactive power ratio. The R

The setting range of the reactive power ratio is 0~100% or 0~-100%, corresponding to
the ranges of inductive and capacitive reactive power regulation respectively.
