17. Reactive power
This section of the menu may be used to manage the supply of reactive
power into the grid. There are 4 possible types of management:
• Disable: no regulation of reactive power. To enable this mode, press
Enter then press Enter to conrm.
• Cos-phi xed: Sets the power rating to a xed value. To enable this
mode, press Enter and set the Cos-Phi value (as either Over or Under
excited, from 1.000 to 0.800); press Enter to conrm.
• Std Cos-phi-0.90: Power rating as a function of the active power sup-
plied by the inverter. To enable this mode, press Enter then press Enter
to conrm.

18. 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.
