Hello,
Your screenshot looks normal to me. Can you tell me what trouble you are having?
Note that the list of variables in the Select Inputs window shows several pieces of information about the variable. For example for the first variable listed in your screenshot, "AC wiring" is the variable label, and "acwiring_loss" is the variable name. The units are "%" and the variable type is "number."
Please see the short video about how to run parametric simulations from this Parametric and Statistical Analysis webinars:
sam.nrel.gov/node/69276
Older versions of SAM only showed the variable name, so the list in the video will look a little different than in SAM 2018.11.11, but the procedure is the same.
Best regards,
Paul.
