Accessing Diagnostic values
Target power output %:
The fields indicates the percentage of the Plant’s DC power determined by the control for the target out-
put.
The detailed values for the individual bus connections and for the total plant are displayed in the following
table below. The individual buses (RS485 A-C) are displayed depending on which bus is assigned to cont-
rol the inverters.
The column
Total always corresponds to the plant total and reflects the value from the grid connection
point. The consumption values are displayed in all of the columns, but only the plant total is taken into
account.
Note!
The values from the individual inverters are calculated per bus and for the entire
plant.
Generator power (kW):
The generator power corresponds to the module output of the inverter that is connected to this data bus.
This value results from the total of the partial outputs entered in the field generator power under configu-
ration | Devices | Configuration. This kW values is used when calculating the output reduction (e.g.: the
70% reduction).
Maximum AC power (kW):
The maximum AC power of the inverter(s) depends on the device. Refer to the inverter specifications for
this value and configure it in the field Maximum AC power under configuration | Devices | Configuration.
Allowed power (kW):
This kW value is the maximum amount of power that is allowed at the grid connection point. The value is
calculated based on the generator output and the current power output.
Consumption (kW):
This value is calculated from the consumption meters and refers to the entire plant. The values displayed
in the respective bus column only refer to the plant total and are not taken into account in the correspon-
ding columns. The consumption value is normally subtracted from the allowed power from the entire plant.
Control value power (kW):
This value is calculated by the Solar-Log™ and is the maximum current power output from the inverters. It
is used for the current target power output.
Note!
Due to technical reasons, the calculation from the Solar-Log™ is subject to a roun-
ding factor. This may lead to deviations in the data recording.
