The TESVOLT A series
Our storage systems meet the highest standards

Durable, high-performance and modular

Our tried-and-tested, multi-award-winning storage systems of the A series have an impressively long lifespan and flexible expandability. The combination of prismatic high-performance cells from Samsung SDI and the unique Active Battery Optimizer (ABO) battery management system offers maximum storage capacity without loss of efficiency even after years of service. The particularly conservative and loss-free cell balancing ensures an efficiency rating of 98% and a lifespan of 30 years or 8,000 full cycles. And as storage requirements increase, individual modules can be easily retrofitted with no loss of efficiency.
Discover long-lasting performance that is flexible enough to adapt to your needs.
