It's a bit confusing that hourly kWh and lifetime kW "electricity to/from grid" are different in these results for the MiniGrid AC case of the DC_AC_Connected.sam test file -- lifetime hourly is zero for all time steps, as I think it should be due to the grid outage for all time steps (this is true in this branch and SAM 2021.12.02 r1):
