Inverter can feed in a fixed reactive power to grid. Users can set the power
factor(cosphi) in Constant cosphi page.
Cosphi (P) is a function that inverter will feed in reactive power when its output
active power reach the setting values. For country Italy MV and Italy LV, users
can set lock-in voltage and lock-out voltage to assign the operation interval.
When grid voltage reach the lock-in voltage(V lock-in), inverter will enable
cosphi (P) function automatically and disabled it when grid voltage reach lock-out
voltage(V lock-out).
