Log file: Entries
The units of the physical variables are followed by vari-
ous entries in the log file
.
The following table explains the various entries of the log
file and may deviate depending upon the model:
Entry
Explanation
Time
Time in seconds of the time since the inverter went into operation
DC x U
DC voltage: Input voltage of the respective string (x = 1, 2 and 3) in V
DC x I
DC current: Input current of the respective string (x = 1, 2 and 3) in mA
DC x P
DC power: Input power of the respective string (x = 1, 2 and 3) in W
DC x T
DC temperature: Details for service. Temperature of the respective phase (x = 1, 2 and 3)
in digital values
DC x S
DC status: Details for service of the respective string (x = 1, 2 and 3)
AC x U
AC voltage: Output voltage of the respective phase (x = 1, 2 and 3) in V
AC x I
AC current: Output current of the respective phase (x = 1, 2 and 3) in mA
AC x P
AC power: Output power of the respective phase (x = 1, 2 and 3) in W
AC x T
AC temperature: Details for service. Temperature of the respective phase (1, 2 and 3) in digital values
AC F
AC frequency: Grid frequency in Hz
FC I
Residual current: Measured residual current in mA
AIn1
AIn2
AIn3
AIn4
Analog input voltage: Display of the analog inputs 1 to 4 of the communication board.
The measured voltage value in V can be calculated with the value from the table (digits) and the following
formula: Input voltage [V]=(10/1024) * digits. If the S0 input is used to count the energy pulses, both table
columns Aln3 and Aln4 give the sum of the energy pulses per log interval. This total value is calculated as
follows: E
total
= AIn3 * 2
