14. Reactive power
This section of the menu may be used to manage the supply of reactive
power into the grid. There are 5 possible types of management:
• No regulation: no regulation of reactive power. To enable this mode,
select Enable and then OK (using the UP / DOWN arrows)
• Cos-phi xed: Sets the power rating to a xed value. To enable this
mode, select Enable and then OK (using the UP / DOWN arrows) When
enabled, Set value will appear on the display, allowing you to set the
value of Cos-Phi (as either Over or Under excited, from 1.000 to 0.800)
• Q xed: Sets the reactive power rating to a xed value. To enable this
mode, select Enable and then OK (using the UP / DOWN arrows) When
enabled, Set value will appear on the display, allowing you to set the va-
lue of reactive power rating (as either Over or Under excited, from 1.000
to 0.001).
• Cos-phi = f(P): Power rating as a function of the active power supplied
by the inverter. To enable this mode, select Enable and then OK (using
the UP / DOWN arrows). When it has been enabled, Load std curve
will appear on the display, allowing you to set the following control curve:

• Q = f(U): reactive power as a function of the grid voltage measured by
the inverter. To enable this mode, select Enable and then OK (using the
UP / DOWN arrows). When it has been enabled, Load std curve will
appear on the display, allowing you to set the following control curve(*):

15. Power reduction
This section of the menu allows you to adjust the limit to the active power
that the inverter can feed into the grid by setting the percentage of nomi-
nal power at which the limit should be triggered.
Setting it to 100% resets the default maximum power, which in some
installation country standards may be 110% of nominal power.
