Constant cosφ
7.2.6.4.3
When this Mode is turned on, inverter will maintain power factor as a constant
value. Users can set power factor from Cap 0.80 to Ind 0.80.
cosφ(P)
7.2.6.4.4
The output power factor would be affected by feeding power. Lock-in voltage and
Lock-out voltage are only adjustable if Country setting is Italy BT or Italy MT.
Inverter would feed-in reactive power depends on active power once Grid voltage
is higher than Lock-in voltage and back to pure active power when Grid voltage is
lower than Lock-out voltage. For the countries other than Italy, cosφ (P) control
will not concern Grid voltage.
