This page includes two kinds of function: active power control and reactive power
control. In active power control function, there are 3 control modes:
Power Limit, Power vs. Frequency, and P(V). In reactive power control function,
there are 4 control modes: Constant cosphi, cosphi(P), Constant Q, and Q(V).

rated power. Users can limit the output power by set the Set Point in Power
