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.
