Configuring connected devices
18�5 Configuring devices
After the Device Detection has been successfully completed, the detected devices have to be defined
in the Configuration | Devices | Configuration menu.
Depending on the device, different settings might be needed for the configuration.
The following devices are listed in the device overview:
•
Inverters
•
Power meters and current transformers (with Solar-Log METER)
•
Sensors
Procedure:
•
Select the device that needs to be configured in the Device Configuration section.
•
Depending on the device type, different configuration boxes appear.
•
The sections below—Module Fields, Power Output and Descriptions—are to a large extent identical
Enter the module field, connected generator power and description
18�5�1 Configuring inverters
The following values have to be configured for inverters:
•
Maximum AC Power
•
Pac Correction Factor
•
Module field
•
Generator Power and MPP tracker output (according to the string plan)
•
Labels or names of the inverters and/or MPP trackers.
Procedure:
•
Select Device
•
Enter
•
the maximum AC power from the inverter's data specification in the section: Module Field, Power
and Name.
•
Enter the Pac correction factor
If the power yield displayed by the inverter is compared with the calibrated current meter, devi-
ations are detected. An approximate correction factor can be defined in order to compensate for
this inaccuracy.
All yield data are stored internally without any correction factor. This factor is applied only when the
data are displayed. The factor can therefore be adjusted at any time.
The formula for calculating the correction factor is as follows:
Yield on power meter / Yield at inverter * 1000
If the inverter does not have a display, the correction factor must be left at 1000 initially, and the fac-
tor can then be determined after about a week or at later times.
•
Define the module field
Inverters can be assigned to be different module fields. See Chapter “18.5.6 Module Fields”.
•
Generator Power
The connected power of the individual inverters in Wp. The total power can be calculated using the
formula: Module power * Number of modules. The output does not have to be entered. It is calcu-
lated from the total generator power values that have been entered for the
Mpp Tracker .
•
The generator power for every tracker needs to be entered if the inverter has several MPP track-
ers.
•
IA distinct name can be assigned to every generator/MPP tracker in the Label box.
