8.7.3.1 Cos-phi Control Mode
Cos-phi control operates with fi ve reactive and active power control ways according to {COSPHI Control Mode}
setting.
No. Power control Description Relative
Parameters
1 Fixed P Control the maximum active power with {Remote
Power Control} parameter value (% of max rated power). {Remote Power Control}
2 Fixed cosphi Control the maximum active power with {Remote
Power Control} parameter value (% of max rated power).
Control power factor with parameter value of {COSPHI
Internal Power Factor} or {COSPHI RPC Power Factor}
according to present RPC status. {Remote Power Control}
{COSPHI Internal Power
Factor}
{COSPHI RPC Power Factor}
3 Fixed Q Control the maximum active power with {Remote
Power Control} parameter value (% of max rated power).
Control reactive power with parameter value of {COSPHI
Internal Reactive Power} or {COSPHI RPC Reactive
Power} according to the present RPC status. {Remote Power Control}
{COSPHI Internal Reactive
Power}
{COSPHI RPC Reactive
Power}
4 Cosphi(P/Pn) Control power factor to match the graph of maximum 10
continuous {COSPHI_n} and {P_n} pairs. {COSPHI_n}, {P_n}
(n = 1 ~ 10)
{COSPHI (P/Pn) {Ramp Time}
5 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 Deadband} and {Q(V)
Control K Factor}. {Q(V) Control Deadband}
{Q(V) Control K Factor}
{Q(V) Control Ramp Time}

8.7.3.2 Communication between Component
Cos-phi Control enables remote control of reactive and active power by setting reference of reactive and active
power by communication between Prolog, MMI, and XCU. Here are the communication methods between each
component.
1. User activates Cos-phi Control by Prolog.
2. Prolog sends a Cos-phi Control massage at two-minute intervals.
3. MMI interprets the Cos-phi Control message from Prolog to modify parameters of XCU.
4. XCU operates according to the modifi ed parameter by MMI.
5. Cos-phi (limited to Fixed cos-phi and Fixed Q) has two overlapping parameters for RPC and Internal modes,
and MMI modifi es the parameter for RPC mode only. If the relative RPC mode parameter is not modifi ed
longer than fi ve minutes, XCU will operate according to the parameter for internal mode.
