A modular battery family for homeowners already leaning toward the SMA ecosystem, especially when solar self-consumption, backup-ready planning, and future expansion matter more than finding the cheapest storage option.
SMA positions Home Storage as a stackable DC-coupled battery that works with compatible Sunny Boy Smart Energy and Sunny Tripower Smart Energy hybrid inverters. The official source set shows a modular design built from 3.28 kWh battery modules, with usable-capacity configurations that scale from 3.28 kWh up to 16.40 kWh depending on module count and inverter pairing.
That modular family design is helpful for real projects, but it also means some single-number MCP fields are not a clean fit for this record. Chemistry, warranty, expansion window, and current limit can be verified directly from SMA's official documentation, while the remaining single-value battery fields are better left blank than flattened into a misleading one-size number.
This page makes the most sense for households or installers already choosing an SMA hybrid inverter and wanting an official battery option with outdoor-rated IP65 hardware, LiFePO4 chemistry, stackable expansion, and strong system fit inside the SMA monitoring and commissioning workflow.
