sonnen’s global vision of clean energy for all: presenting the sonnenBatterie and the sonnenCommunity.
During the day the sonnenBatterie optimizes the use of self-generated solar power, saving money on household electric bills.
The sonnenBatterie easily integrates with new and existing solar systems to manage power for households, both day and night.
The sonnenBatterie reliably supplies energy during the night time using the stored solar power generated during the day.
In the inter-connected sonnenCommunity in Germany, all members share their self-generated and stored energy with one other in a clean energy marketplace.
Integrating the sonnenBatterie provides true energy autonomy by enabling homes to generate and store their own energy, even during power outages.
sonnenBatterie manages energy usage, increasing household energy efficiency and reducing energy costs throughout the day.
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.
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.
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!
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.

At sunrise the solar panels start to produce energy, though not enough to cover the morning energy needs. The sonnenBatterie will bridge the gap with the stored energy from the previous day.
In the daytime the energy generated from the solar panels is at its peak. But since nobody is home the energy consumption is very low so that most of the generated energy is stored in the sonnenBatterie.
The highest daily energy consumption is in the evening when the solar panels produce little or no energy. The sonnenBatterie will cover the energy need with the energy produced in the daytime.
As a young and upcoming company, sonnen GmbH has been honored for its innovative products and fast growth for several times. This proves that our vision of a future characterized by clean and decentralized energy supply is the right way to go.
The sonnenBatterie residential and commercial storage systems only use lithium-iron phosphate (LiFePO4) battery technology, one of the most reliable, safe and long-lasting lithium battery technologies currently available. LiFePO4 is one of the most popular technologies for stationary storage systems due to its uniquely high chemical stability and resulting extremely high application reliability, durability and long life. Our battery systems are guaranteed to last for 10,000 cycles or 10 years. All sonnenBatterie components and systems are also UL Listed ensuring safety and performance for your home or business.
The sonnenBatterie is a complete system - ready for connection. This means that inside of every sonnenBatterie you'll find not only the extremely durable battery modules but also an inverter, an intelligent energy manager, measurement technology and the software to operate it all smoothly. All in one handy box. In contrast to most other battery systems in the market the sonnenBatterie components are build into a single high-quality casing and perfectly attuned to each other - thereby ensuring maximum longevity and the highest quality in a minimum of space.
