TS 48 V Lithium Storage System

  • Can be flexibly expanded in 4.8 kWh increments
  • Three different rack sizes
  • Optimised for use with the SMA Sunny Island
  • Flexible configuration and expansion possible, even years down the road
  • Built to last 30 years or 8,000 full cycles
  • 1C charging speed
  • Utmost cell technology safety


The TS 48 V lithium storage system offers outstanding flexibility and can be optimally adjusted to suit any application. Its cutting-edge prismatic lithium battery cells from Samsung SDI and innovative technology like the Active Battery Optimizer ensure outstanding efficiency and performance.

The system is designed to last 8,000 cycles or a lifespan of 30 years, guaranteeing excellent cost efficiency. Its modular construction makes exchanging individual battery modules a breeze, and the capacity can be expanded even years later.

With its continuous power of 1C, the TS 48 V storage system can charge and discharge in next to no time, making it ideal for professional use in commercial applications, agriculture and industry.

Areas of application

All TS lithium storage systems are suitable for both off-grid and on-grid use and can be flexibly combined with any type of energy generator such as photovoltaic, bioenergy, wind power or diesel generators.

Increase self-consumption

Use more of the power you generate and cut your electricity costs

Emergency power

In the event of a mains failure, your storage system takes over the power supply

Diesel hybrid optimisation

Use the system to optimise your diesel hybrid consumption

Off-grid power supply

Build your own independent utility grid with technologies such as photovoltaic installations

Time of use

Store electricity in the battery at a favourable low tariff and use it as required at high-tariff periods

Modular principle

TS storage systems can be flexibly adapted to suit your application. Choose your desired capacity in 4.8 kWh increments. One Active Power Unit (APU) can control up to 16 battery modules. Three different racks are available as housing for up to five, eight or 10 battery modules. The 1-phase or 3-phase connection and the connected load determine the number of battery inverters required.
