Data Logging
The GT100 inverter stores data values and software metrics for debugging. The firmware
maintains a data log located in the CCU2 non-volatile memory with a capacity of 25840
32-bit words. The GT100 records the 17 parameters listed below, and logs them into a
circular buffer, such that the earliest records shall be overwritten once the capacity of the
buffer is exceeded. The log capacity is 25840 / 20 = 1292 records (each record has 2
words for timestamp and 18 words for parameters). Data logging requires the use of a
PC connection using the GT View Graphic User Interface (GUI) software or via the
RS485/Modbus connection.
The following is the list of parameters which values shall be stored in the data logging
records:
•
Inverter Vab
•
Inverter Vbc
•
Inverter Vca
•
I Phase A
