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.
sonnenVPP
The sonnenVPP is the key to our energy transition that provides clean, reliable, and affordable energy for everyone — a true win-win-win: for customers, communities, and our planet.
