10.10.2 Reactive Power Regulation
The inverter provides reactive power regulation function. Use the “Q-Var switch”
parameter to activate this function and select proper regulation mode.
Regulation Mode Explanation
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 %).
Off
The PF is limited to +1.000, and the “Q-Var limits” is limited to
0.0%.
Q(P) The PF changes with the output power of the inverter.
Q(U) The reactive power changes with the grid voltage.
“Pf” Mode
The reactive power can be regulated by the parameter PF on the Run-param screen.
“Qt” Mode
The reactive power can be regulated by the parameter Q-Var limits (in %) on the
Run-param screen.
“Off” Mode
The PF is limited to +1.000, and the Q-Var limit is limited to 0.0%.
“Q(P)” Mode(when the country selection is not “IT”)
The PF changes with the inverter output power.
If the country selection is not “IT” (Italy), after
selecting Q(P) Mode, Press j to enter the
Run-param-Q(P) sub-menu.
For each item setting, Press h to move cursor right
and Press j to set the appropriate value. Confirm
settings by Press ENTER.
