SMA Storage M Battery Storage 24.6 kWh – Storage M 24.6

SMA Storage M Battery Storage 24.6 kWh – Storage M 24.6

Modular high-voltage home storage system with 24.6 kWh lithium iron phosphate capacity – plug and play, flexibly expandable up to 49.1 kWh, for residential and small commercial photovoltaic systems.

The SMA Storage M 24.6 is a modular PV storage system, i.e. high-voltage battery storage system for home users and small commercial applications based on proven lithium iron phosphate technology – ideal for storing solar energy and maximising self-consumption. With 6 battery modules of 4.09 kWh each and a usable capacity of 24.6 kWh, this set provides above-average storage capacity for households with high self-consumption potential, heat pumps or electric vehicles. The central BMS manages all battery modules together. The stackable design without internal cable connections enables quick plug and play commissioning as well as straightforward expansion within two years. Thanks to IP66 and an operating temperature range of -20°C to +50°C, the system is suitable for both indoor and outdoor installation. The SMA Storage M is compatible with the SMA Sunny Tripower Hybrid X (5–30 kW) and the SMA Sunny Boy Smart Energy.

Scope of Delivery

• 1× SMA Storage M BMS Unit (STM-BMS-10)
• 6× SMA Storage M Battery Module (4.09 kWh each)

Features

• Designed for dynamic tariffs: LFP technology for frequent charge and discharge cycles – up to 7.2 MWh/kWh guaranteed energy throughput, suitable for dynamic electricity tariffs, energy trading and VPP scenarios (virtual power plants).
• Plug and Play installation: Stackable modules without internal wiring – automatic commissioning, SOC/state of charge display via LED.
• Central BMS: One BMS unit manages all battery modules – simpler system architecture and more efficient battery management compared to module-internal BMS solutions.
• High charge/discharge current: Up to 50 A in combination with the Sunny Tripower Hybrid X – ideal for frequent charge/discharge cycles, backup and emergency power scenarios.
• Flexibly expandable: Expandable within two years to up to 49.1 kWh (12 modules) by adding further battery modules.
• Indoor and outdoor use: IP66, temperature range -20°C to +50°C – compact design for virtually any installation location.
• 10-year warranty: Upon registration within 30 days of commissioning via my.sma-service.com.

Expansion and Scaling

The SMA Storage M 24.6 can be expanded step by step within two years with additional SMA Storage M battery modules up to 49.1 kWh (12 modules). In combination with the Sunny Tripower Hybrid X 5–15 kW, up to 9 modules (36.9 kWh) are possible; with the Sunny Tripower Hybrid X 20–30 kW, up to 12 modules (49.1 kWh). In combination with the Sunny Boy Smart Energy, up to 7 modules (28.7 kWh) are possible.

SMA Storage M vs. SMA Home Storage

Both SMA battery storage systems use proven LFP technology and are compatible with SMA hybrid inverters – but there are key differences: the SMA Storage M is significantly more scalable (up to 49.1 kWh vs. max. 16.4 kWh for the Home Storage) and features a central BMS for all modules. In combination with the Sunny Tripower Hybrid X, the Storage M enables a higher charge/discharge current of 50 A compared to 36 A for the Home Storage. The Storage M is designed for the Sunny Tripower Hybrid X and the Sunny Boy Smart Energy – those with an existing system using the Sunny Tripower Smart Energy should continue to use the SMA Home Storage.
