Wait, really?!?
I’m completely new to the area of home backup, but this announcement is in-line
with the time that I’m researching solar for our home (on-grid). It doesn’t
make sense given our 1-2day/year electricity outages to backup. Even with that
though, how is $5k possible?

Their 9.6kWh system is $6.79k - am I completely misunderstanding something?
thanks,
