## About this series

The SMA Home Storage series is a modular energy storage solution for home installations, designed to be easily adapted to actual consumption patterns and expandable without replacing the entire system. The key feature is its **stackable modular structure** - capacity increases with each additional segment, and installation can be either floor-mounted or wall-mounted, even in spaces with limited room. The applied chemistry, **LFP (lithium iron phosphate)**, supports thermal safety and stable performance during frequent cycling, which is crucial for photovoltaic self-consumption and dynamic tariff charging. For the user, the combination of **high cycle durability** and **long warranty** is essential - in practice, this means years of intensive energy storage without concerns about rapid capacity degradation. The system is **compatible with hybrid inverters from SMA**, facilitating integration into grid-connected systems with backup power options. This solution is tailored for homes and small businesses - where scalability, predictable longevity, and a cohesive energy management ecosystem matter.
