Is the point of the battery not to add 9s with solar?

Yes the point of batteries is to add backup power when solar goes down - and it does. However the two of them do not get to 4 9's of uptime which is needed for these large data facilities.

At least in my personal use - which is admittedly far smaller - I just see the battery as the main source. Solar exists to charge it.
