This stuf is maybe here and there a little rough around the edges. I do not intend to give allot of user support. So you're basically on your own with this.

For an isolated rs232 interface used with this logger see: https://github.com/hvegh/Optical-Isolated-RS422-RS485-interace.git

General utillities:

• Perl v5
• GNU Compiler
• GNU Make
• swig

Perl modules:

• LWP::UserAgent
• HTTP::Request provided by libwww-perl
• Device-SerialPort provided Device-SerialPort

0. Install prerequisites

   apt-get install swig libdevice-serialport-perl libwww-perl

   Fix permissions on the serial port, if needed:

   chmod 666 /dev/ttyS

1. Compile the Solar Position Algorithm look at the README in lib/spa

2. Set the configuration parameters in sunmon.pl

3. run sunmon.pl

4. Setup the script to run daily, using crontab for example, the script will wait for sunrise before it starts sampling the inverter and terminates on sunset.

tools/analyse.pl:

• Calculates line impedance using PV-Logger data files, use the -h option for a description. The tools directory also contains an example data file.
• Can convert CSV files to JSON for use with index.html. Example: analyse -j data.json example-datafile.csv

tools/index.html:

• Together with a 'data.json' datafile generated by sunmon.pl or analyse.pl, index.html generates solar production charts. Uncomment and configure 'data_js' in the configuration section of the sunmon.pl for live charts.
