SMA Business Storage Systems

Overview

 SMA is one of the most respected inverter and energy management manufacturers in the world, and their commercial battery storage offering, SMA Business Storage, is built in partnership with German battery specialist TESVOLT. The result is a fully integrated commercial and industrial storage system combining SMA's inverter and energy management expertise with TESVOLT's proven battery technology. 

SMA Storage package

The current generation of SMA Business Storage pairs the SMA Sunny Tripower Storage X three-phase battery inverter with TESVOLT's TS HV 30-80 E battery range, consisting of the TS HV 30 E, TS HV 50 E, and TS HV 80 E. The Sunny Tripower Storage X offers faster reaction and control times and a broad usable DC voltage range compared to the previous generation.

Systems are highly scalable, multiple units can be combined to achieve a total energy capacity of up to 5MWh, making the range suitable for everything from small commercial premises to larger industrial facilities.

Key specifications:

• Inverter: SMA Sunny Tripower Storage X (three-phase)
• Battery: TESVOLT TS HV 30 E / 50 E / 80 E (high voltage LFP)
• Battery cells: Samsung SDI prismatic cells, latest generation
• Cycle life: up to 8,000 cycles
• Expected lifespan: up to 30 years
• Warranty: 10 years on system and performance
• Scalable up to 5MWh across multiple units

Applications

SMA Business Storage is designed for commercial and industrial use across the following applications:

• Maximising on-site use of solar generation
• Peak load shaving: reducing demand charges during expensive peak periods
• Time-of-use arbitrage: charging cheaply overnight and discharging during peak hours
• Grid services: the system's fast response capability makes it suitable for frequency response and other flexibility market participation via an Aggregator

Battery technology

The battery component is manufactured by TESVOLT, a German specialist in commercial and industrial energy storage. TESVOLT uses prismatic Samsung SDI battery cells, a format that is highly durable and safe, and whose large physical size allows each cell to be monitored and managed individually, enabling efficient and long-lasting system operation.

The key differentiator in TESVOLT's battery management is Active Battery Optimisation, a cell balancing system that uses bi-directional flyback converters to individually balance the state of charge of each cell within a stack. This is more effective than the uni-directional charge pumps used in simpler systems, enabling faster and more efficient balancing and significantly extending cell life. This technology underpins the 8,000-cycle rating and 30-year lifespan of the system.

The system can be configured with either a Basic or Pro energy management system depending on the level of monitoring and optimisation required.
