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 invert-
ers.
Prior to installation please check whether power management and reactive power con-
trol 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 supported functions of a particular inverter:
Interface section
Depending on the type of Solar-Log™, the interfaces for communication with the connected inverters are
shown here.
Depending on the model used, this list can also contain different entries.
Select the interface or interfaces that correspond to those of the connected inverters.
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%).
•
Control value power (% AC):
The control value is the value sent to the inverters in order to reach the target value. The relationship
between the nominal power (AC) and the installed DC power (DC) is factored in. The current con-
sumption from the control with self-consumption is also factored in.
The value of 100% is not displayed on the LCD display.
