sonnenBatterie eco -
a declaration of independence for your home

The sonnenBatterie eco is an energy storage solution that utilizes intelligent energy management software. It is easily adaptable to your individual needs. The system is available in a variety of storage capacities and configurations, allowing for extensibility and expansion. sonnenBatterie eco allows you to save money every single day by harvesting energy from your solar PV system or the grid when it is cheapest, and using the stored energy from the battery to power your home when rates are more expensive.

Use solar energy throughout the day and at night

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


Never Worry About the Lights Going Out

sonnenBatterie eco 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!


Harvest Cheaper Energy to Use Later

sonnenBatterie eco 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 eco is the right choice for every home and every budget.
