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
Reactive power cannot be regulated. The PF is limited to +1.000, and the Q-Var limit
is limited to 0.0%.
