I finally set up the Outback skybox and it is great. I got 2 x EG4 batteries so I wanted to post my settings to have people check if I could optimize the system even more.
One of the challenges was to get the skybox to use battery whenever the LCOE (levelized cost of energy) is lower than the grid TOU rates. Right now, I'm using self consumption and it is using the battery but not exactly the way I want the skybox to.
