sonnenBatterie Smart Energy Storage for Homeowners. sonnen’s mission is to provide clean and affordable energy for all. The all-in-one sonnenBatterie energy storage products integrate with new and existing solar power systems to turn your house into a smart energy home — using more of the solar energy you generate during the day to provide at night and to keep your lights on when the grid goes down.

sonnenBatterie lets you enjoy the benefits of solar energy production 24-hours a day! The integrated smart electronics manage energy use throughout the day, detecting when there’s excess power and storing it for use at night.

sonnenBatterie allows you to engage in “rate arbitrage” — storing energy when it is cheap and running your home off the battery when rates go up. The sonnenBatterie is the right choice for every home and every budget.

sonnenBatterie is specifically designed to provide you and your family peace of mind in the event of a power outage. Our unique power detection system will sense outages in real-time and automatically switch over to battery power.

A sonnenBatterie integrated with solar panels allows your home to produce and store 100% of the energy it uses — depending on climate and sun exposure — enabling your home to be energy self-sufficient.
