A password is required to enter Active / Reactive Power page.
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).
These modes will be introduced in next section.
- All function’s voltage settings used by phase voltage. -
This control mode can reduce the output power to a percentage of inverter’s
rated power. Users can limit the output power by set the Set Point in Power
Limit page.
Inverter will reduce output power when grid frequency rises up if this mode
enabled. Users can tune the parameters in Power vs. Frequency page to
change the inverter’s behavior.
