• The SunSpec files
• The proprietary inverter protocol files
To create modbus definition files, see section 3.1.2.2.2.3: “Modbus”.
Launching a device scan makes it possible to automatically generate its definition file and to
upload it to the “DEF” directory on the FTP server. It is also possible to build your own
definition file or to modify the automatically generated one.
A new definition file or a modification to one of the definition files is automatically retrieved
by the concentrator at its next connection to the FTP server.
The definition file name can be customised, by default it has the following format:
<uid>_<interface>_<comment>.csv
Where:
• <uid>: Concentrator identifier
• <interface>: the interface name from a defined list (see section 3.1.2.2.2: “Definition
file content”)
• <comment>: free user field
Examples:
WPM00C44F_SunSpec_inverter_SMA_Solar_Inverter_9301_modbusTCP.csv
WPM00C44F_IO.csv
custom.csv
4.1.3 “DATA”
Data is uploaded to the “DATA” directory on the FTP server in the form of CSV format files
compressed to Gzip “.gz” format.
Below is the data file name format:
<uid>_<interface>_<timestamp>.csv.gz
Where:
• <uid>: Concentrator identifier
• <interface>: the interface name from the following list:
o TIC
o IO
o MODBUS
• <timestamp>: The timestamp format is “YYMMDD_HHMMSS” so that an alphabetical
sort of the directory gives the chronological order
