Describe the bug
Self consumption metrics always show the load is met for the full year in the PVWatts-Wind-Battery configuration. This is due to an error in how load is processed in some of the powerflow metrics

To Reproduce
Steps to reproduce the behavior:

1. Run the cases in the attached SAM file
   self_consumption_metrics_error.zip

2. The self consumption metrics are computed properly for PV+Battery

3. The hybrids case does not show anything meeting the load, and all of the generated energy being pushed to the grid

Expected behavior
Powerflow metrics should include the load
