The tests are failing - most likely due to the default changes. Can you run all the default configurations and check test_results_win64.csv for valid results and then commit and push those results for Travis to match?

Layout of new O&M cost inputs looks nice.
- Be sure to add/update UI group name so inputs appear in groups with other related variables in lists for LK script editor, parametrics, etc.
-
I think I would prefer these UI forms to be named "O and M Costs PV", "O and M Costs Fuel Cell", etc. so they appear together in the IDE to make them easier to find when working on these O&M input variables.
-
Cash flow tab is showing "not found" for several items under "LCOS CALCULATIONS".
cashflow for correct output variable names

I'm getting these messages when I create a new PV Battery / Single Owner case:
No default value found for 'wf_nrecords' in external file (PV Battery/Single Owner), using internal default
No default value found for 'vdcmax_inverter' in external file (PV Battery/Single Owner), using internal default
Defaults file is likely out of date: PV Battery_Single Owner.txt
Variables: 1 loaded but not in configuration, 0 wrong type, defaults file has 1130, config has 1131
Would you like to update the defaults with the current values right now?
(Otherwise press Shift-F10 later)
Loaded but don't exist in config: ui_batt_is_dc
