Note!
The active power reduction mode that needs to be implemented for a particular PV plant
is determined by the current national laws, standards and grid operator's requirements.
The planner and/or installer of your plant or the respective grid operator can provide
you with information regarding the mode of active power reduction that needs to be
used.
Note!
The feed-in management functions are not supported by all makes and models of inver-
ters. Prior to installation please check whether power management and reactive power
control are supported by the inverters used. Please consult our inverter database for an
overview of all the inverters supported by Solar-Log™ devices and more details on sup-
ported functions of a particular inverter:

Interface assignments section
The inverters with their assigned interfaces that are connected to the Solar-Log™ are displayed in this
section.
Select the inverter(s) to control and activate it/them.
LCD Display
In the LCD Display section, the values that are displayed can be defined.
The following values can be selected:
•
Only error:
This is displayed when there are PM control errors.
•
Target power (% DC):
This is the value (%DC) that has been selected for the reduction (e.g. 70%).
•
Percentage of consumption (only selectable when the “Percentage of consumption for an adjustable
reduction” has been defined under type):
Value, which was entered for “Percentage of consumption for an adjustable reduction”. 100% will nor
be visulized, because the LCD display can only display 2 digits.
•
Control value power (% AC):
The control value is the value sent to the inverters in order to reach the target value. The relations-
hip between the nominal power (AC) and the installed DC power (DC) is factored in. The current
consumption from the control with self-consumption is also factored in.
The value of 100% is not displayed on the LCD display.
