Cosphi(P/Pn) Control power factor to match the graph of maximum 10 conti-
nuous COSPHI_n and P_n pairs.
The cosphi (P/Pn) function allows the inverter to send a change-
able PF (power factor) according to the active power to grid. The
maximum setup point of both PF and active power is 10 points.

Q(V) Control reactive power infusion from inverter to grid when grid
voltage is between rated range. The grid voltage range where
Q(V) function is possible is determined by Q(V) Control Dead-
band and Q(V) Control K Factor.

The Q(V) control function is used to feed reactive power, even if
the grid is in normal range (90 ... 110%).
Q(V) Control K Factor = ΔQ/ΔU
• ΔQ = cosφ = 0.95
• φ = 18.2°
• sinφ = 0.31
