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 temperature: Details for service. Temperature of the respective phase (x = 1, 2 and 3)
DC x T
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 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
AIn2
formula: Input voltage [V]=(10/1024) * digits. If the S0 input is used to count the energy pulses, both table
AIn3
columns Aln3 and Aln4 give the sum of the energy pulses per log interval. This total value is calculated as
AIn4 follows: E
AC S AC status: Details for service of the operational status of the inverter
ERR General malfunctions
Status of the ENS (device for grid monitoring with assigned switching elements):
ENS S
Status of grid monitoring
ENS Err Malfunctions of the ENS (device for grid monitoring with assigned switching elements)
SH x P External current sensor power: Power of the respective phase (x = 1, 2 and 3) in W
SC x P Self-consumption at the respective phase* (x = 1, 2 and 3) in W
HC1 P Is not used
HC2 P
Home consumption in W from the PV modules
HC3 P Home consumption in W from the grid
KB S
Internal communication status when switching to AC grid
Total E Total energy: Total fed-in energy in kWh when switching to AC grid
HOME E Home consumption: Energy currently used in the household in kWh
Iso R
Insulation resistance in kOhm when switching to AC grid
Event POR event, "power on reset": Renewed start-up of communication after a loss of AC voltage.
