Reactive Power Limit
There are four modes of reactive power limitation which can be selected.
◼
Cos(phi) fix mode: In this mode, the AiCom/AiCom WiFi will regulate the
reactive power of inverter according to the Cos(phi) value which is set by the
user. Enter the Cos(phi) value and choose the phase as shown in Fig. 6-10.

◼
Cos(phi) variable mode: In this mode, the AiCom/AiCom WiFi will produce a
curve according to the “P/Pn”, “Cos(phi)” and the phase of points 1,2,3 and 4,
and will regulate the reactive power according to this curve, as shown in Fig. 6-
11.
