A self-powered home combines solar energy and sonnenCore to independently power your home day and night. During the day, solar panels may produce more energy than your home uses. sonnenCore stores that excess solar energy for on demand solar self-consumption, time of use load shifting, backup power, and off-the-grid use, even after the sun has set. 


A sonnenCore+ Residential Battery Backup offers a sustainable option to a gasoline or propane generator.
