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
