How It Works
Simple. Automatic. Silent.
01
Stores excess solar energy
During the day, your solar panels charge the battery with energy you'd otherwise send to the grid.
02
Powers your home at night
After sunset, the battery supplies your home — reducing what you pull from the grid.
03
Automatic outage protection
When the grid goes down, EP Cube switches over in seconds. Your lights stay on.
04
Expandable
Start with one unit and add more as your needs grow. Stack up to four EP Cube units for whole-home backup.
