Parameters
8.7.9 The Relationship of Reactive Power and Active Power
While active and reactive power is set to exceed maximum complex power (1.11P
Rated
) by parameter setting,
COSPHI Control reduces active power, and control reactive power by parameter setting.
8.7.10 Cosφ (P/Pn)
The Cosφ (P/Pn) function allows inverter to send changeable PF (power factor) according to the active power to
grid. The maximum setup point of both PF and active power is 10 points and the maximum required value of
PF for Cosφ (P/Pn) is 0.9 in German market. XP-HV and XP-TL series can also operate with maximum PF, which
is 0.9, and its transient time is 10sec.
