SMA Storage M BMS

SMA Storage M BMS

The SMA Storage M is a modular high-voltage home storage system based on long-life LFP technology, designed for domestic users and small businesses. The system is available in capacity ranges from 12.3 kWh to 49.1 kWh per tower and can be flexibly expanded by simply stacking additional modules – without the need for complex internal cabling. Thanks to plug-and-play commissioning, IP66 protection and an operating temperature range of −20 °C to +50 °C, the Storage M is suitable for both indoor and outdoor use. When combined with the Sunny Tripower Hybrid X or the Sunny Boy Smart Energy, it forms a fully integrated and reliable solar energy solution.

Product benefits:

• Designed for frequent charge/discharge cycles – ideal for dynamic tariffs, energy trading and VPP scenarios
• Up to 7.2 MWh/kWh guaranteed energy throughput (depending on the country of installation)
• 10-year warranty for long-term cost-effective operation
• Plug-and-play installation with no internal cable connections between the modules
• Flexibly scalable from 12.3 kWh to 49.1 kWh per tower – expandable within two years
