Beyond Backup
Batteries aren't just for backup.
Your utility charges more for electricity during peak hours — usually late afternoon and evening. A battery quietly shifts you off the grid during those expensive windows and back on when rates drop, so you avoid the highest charges every single day.
Fill up when power is cheap
Your battery charges from solar during the day, or from the grid overnight when rates are lowest.
Skip the expensive hours
When peak pricing kicks in, your home draws from the battery instead of the grid — avoiding the priciest kilowatt-hours of the day.
Lower bills, every month
You're still connected to the grid — you just use it when it's cheap and lean on your battery when it isn't.
