The biggest point to batteries is a Continous UPS for the entire system. If you loos main AC power then you are running your house off of the entergy stored in the Batteries. That is also how Datacenters are run. They have a centralized Battery plant that all Devices run from. The power ALWAYS comes from the batteries so there is no chance for an interupption in power.
