I'm not familiar with that inverter, but you should be able to get
general logging data from the port. If you're *very* lucky it'll have
telnet console.
Point Wireshark at the interface:-
# apt-get install wireshark wireshark-doc
Then take a look at pv:-

Originally I looked at this:-
http://www.solarfreaks.com/cms2000-inverter-rs232-serial-port-hack-cms-2000-rs232-t271-160.html
but it's pretty dated now and may have changed.

You may also get some useful information from your local LUG:-
