Get to know sonnenCore+.

Does sonnenCore+ pair with my solar array?: Yes, sonnenCore+ is designed to work with any new or existing solar systems to store excess energy from the sun and the electricity grid. The smart battery management software intelligently controls when the stored energy is used to power your home - during peak times of day, at night or in an outage. While you can install a sonnenCore+ without solar, we recommend pairing it with solar to power your home with clean energy and keep the lights on during longer outages. Please consult with your sonnen certified installer to design the system that is right for your home.
Does sonnenCore+ provide backup power?: Yes! Like all sonnen home batteries, the sonnenCore+ protects your essentials from power outages, including keeping your lights on, your home network running and your refrigerator cold (up to 20kWh). The number and kinds of appliances you can backup varies. Please consult with a sonnen certified installer on your backup power needs to design a system that is right for your home.
What type of applications can sonnenCore+ be used for?: Access to stored solar power 24/7. Store clean, abundant energy to use later — reducing your carbon footprint and powering your home with the cleanest energy available.

Use more of your own solar energy. Reduce your reliance on grid power during peak demand periods with smart energy management.

Backup what matters most. Automatically switch to emergency backup power to keep key devices and your solar up and running.

Control your energy anytime, anywhere. With my sonnen App and customer dashboard you have access to optimize your battery settings for backup, peak periods, and solar usage and monitor your energy on demand.

Contribute to a more resilient grid. Enroll your sonnenCore+ battery in local utility programs to share your clean power, earn cash back, and reduce emissions.
