The reactive power regulation function is disabled. The PF is fixed at +1.000.
" " P P F F " " M M o o d d e e
The power factor (PF) is fixed and the reactive power is regulated by the parameter PF.
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.
" " Q Q t t " " M M o o d d e e
In the Qt mode, the reactive power can be regulated by the parameter Q-Var limits (in
%). The system rated reactive power is fixed, the system injects reactive power
according to the delivered reactive power ratio. The "Reactive Power Ratio" is set
through the App.
The setting range of the reactive power ratio is from -100 % to 100 %, corresponding to
the ranges of inductive and capacitive reactive power regulation respectively.
" " Q Q ( ( P P ) ) " " M M o o d d e e
The PF of the inverter output varies in response to the output power of the inverter.
