Smart energy Storage
sonnen Battery:
a reliable investment in your future
Cover up to 80% of your energy needs with your own solar power
sonnen offers reliable storage solutions for your solar system. It allows you to use your solar energy exactly when your household needs it. Instead of using only around 30% of your annual solar production, a sonnen storage system lets you cover up to 80% of your electricity needs with energy from your own roof, making it the smartest and most cost-effective solution.
Day or night, sonnen keeps you connected and in control.

Morning
As the sun rises, your solar system begins producing electricity. However, the early sunlight usually isn’t enough to fully meet your energy needs. That’s where your battery steps in — powering your home with stored energy from the day before.
Midday
During the day, your solar system produces the most energy. When production exceeds your consumption, your battery stores the excess electricity, making it available later when it’s needed.
Evening
As energy demand rises and your solar system produces little to no power, the battery takes over — delivering stored solar energy for sustainable electricity use even after sunset.

What makes sonnen unique
Lithium iron phosphate (LFP) battery cells
From the very beginning, we've chosen lithium iron phosphate (LFP) technology for our batteries, because it's safer, longer-lasting, more sustainable, and better for the environment than other battery chemistries. LFP battery systems deliver high efficiency and an exceptionally long lifespan, all without relying on problematic raw materials like cobalt.
In-house battery research
In sonnen’s battery lab, our experts test the latest storage technologies to shape a sustainable energy future. Rigorous testing procedures ensure the highest levels of safety, efficiency, and durability. Extreme stress tests simulate decades of use, while our energy storage systems are continually refined for the smart energy grids of tomorrow.
The Best Battery for Reliable VPP Operation
sonnen’s latest battery technology offers the fastest VPP integration on the market, making it the best choice for Virtual Power Plants. Its advanced electromagnetic design ensures optimal outdoor performance and surpasses other outdoor batteries in both speed and reliability, making it ideal for smart, responsive energy networks.
The night belongs to sonnen
It’s that simple: during the day, you benefit from the sun — at night, from your intelligent sonnen Battey. Our all-in-one system uses smart energy management to deliver long-term savings and efficiency, day after day and year after year.
