TS 48 V lithium storage system

The flexible one with the plus for performance

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

As flexible as your application

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.

Overview of all application areas

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.

Self-Consumption Optimisation
Use more energy from renewable sources and minimise feed-in

Back-up Power
The storage system immediately takes over the power supply in the event of a power outage

PV-Diesel-Hybrid-Optimisation
TESVOLT solutions optionally adjust the power grid and balance generation and consumption peaks to keep the diesel generator in optimal operation, minimizing diesel costs

Off-Grid
Create your own power grid independently of energy suppliers, for example by combining a photovoltaic installation and TESVOLT storage solution.

Time of Use
Time-dependent use of functions.

Charging Station Control
Smart interconnection of the charging station and central controls via the TESVOLT Energy Manager. This means charging processes can be digitally recorded and controlled.

Micro-Grid
Supply of a small power grid with and without connection to a public power grid; here, the battery provides part of the power grid, for example, when only a limited grid connection is available.

Forecast-Based Charging
Depending on the weather forecast, curtailment losses from photovoltaic installations are avoided and self-consumption is optimised.

Ancillary Services
Remote control of active and reactive power.

Zero Feed-In
Fulfils the normative guidelines (Germany) stipulating that no power can be fed into the utility grid.

Direct Marketer Interface
Enables the connection of direct marketers for the marketing of electricity from renewable energies.

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.
