Describe the bug

If a user unchecks the "save all output variables over analysis period" and tries to run a grid outage simulation, SAM crashes.

To Reproduce

Steps to reproduce the behavior:

1. Set up a behind the meter, detailed PV + battery simulation (tested with host developer)
2. On the "DC degradation" page, uncheck the "save all output variables over analysis period" box
3. Set up a grid outage (tested with 100% crit load and an outage in every timestep
4. Run the simulation
5. SAM crashes

Expected behavior

SAM should not crash in this scenario
