Disruptive, longer power outages
When a power outage occurs, home battery systems only keep the power on in the select rooms & appliances designated by you at installation. If you need power elsewhere in your home or a boost to your battery life in an outage, you’re often left in the dark with the hard-wired decisions you made at install.
