There are two options for seeing the CEC inverter database parameters:
In SAM, you can use a text editor to open the .samlib file that stores the library parameters in SAM. The file is called SandiaInverters.samlib, and is in the SAM libraries folder ...\exelib\libraries, which is in the SAM installation folder (c:\SAM\2011.12.2 for the Windows version of SAM 2011.12.2).
Another option is the set of inverter test summaries that the CEC provides on the Go Solar California website. The data are provided in a separate PDF file for each inverter at:
