## SMA Storage M BMS Unit - Battery Management System


The SMA Storage M BMS Unit acts as the central controller and brain of the modular high-voltage Storage M battery storage system. This management unit controls communication and monitors the status of the stacked battery modules. The device regulates energy distribution during daily frequent charge and discharge cycles. The unit is prepared for dynamic electricity tariffs, energy trade, and virtual power plant (VPP) scenarios. Setup is completed quickly via automatic plug-and-play commissioning without complex internal wiring between components.


You choose a central interface within the residential and light commercial energy ecosystem with this model. The device communicates directly with the coupled hybrid inverters to guarantee stable energy storage. The weather-resistant housing allows for both indoor and outdoor installation and operates reliably under varying conditions.



### System Components and Scaling Options


- **complete starter kit**: to immediately begin installation, you can choose the **[SMA Storage M Basic Kit](https://www.estg.eu/en-gb/p/STM-BMS-3BM-10)**, which contains exactly one central BMS unit and three battery modules.
- **individual battery module**: for flexible capacity scaling, you can add the **[SMA Storage M Battery Module](https://www.estg.eu/en-gb/p/STM-BM-4.09-10)**, featuring durable LFP technology and a weight of 36 kg.



### Advantages of SMA Storage M BMS Unit


- **clear status tracking**: the state of charge (SOC) is visible directly via the integrated led indicators on the front panel.
- **wide compatibility**: the device operates seamlessly with single-phase and three-phase hybrid inverters from the same ecosystem.
- **high enclosure rating**: the ip66-certified housing permits safe indoor or outdoor placement in damp or dusty environments.
