TS 48 V lithium storage system

When flexibility is needed

  • Can be flexibly expanded in 4.8 kWh increments
  • 3 different rack sizes
  • Optimized 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
  • The safest cell technology

Perfectly adaptable for every application

The TS system is not only flexible and can be optimally adjusted to suit any application, it is also one of the most advanced and efficient storage systems on the market.

All the components of our storage systems are designed to last 8,000 cycles or offer a 30-year lifespan, thereby guaranteeing excellent cost efficiency.

Thanks to high-quality battery cells from the automotive industry and innovative technologies, such as the Active Battery Optimizer, our TS storage system is one of the safest and most efficient products on the market.

TS storage systems can store energy very quickly, and release it again just as quickly. With a discharge rate of 1C – and even 4C for short periods – the storage system is optimized for professional use in commercial applications, agriculture and industry.

Our TS storage systems not only offer flexible configuration options at the moment of purchase – thanks to the innovative Active Battery Optimizer technology, the capacity can also be expanded years later.

Areas of application

TS storage systems can be integrated into stand-alone grids or connected to the public power grid. They can be flexibly combined with any energy source, including photovoltaics, bioenergy, wind power and diesel generators.

Emergency power:
in the event of a power failure, your storage system is ready to supply power in a split second

Increased self-consumption:
use more of the power you have generated and save on electricity costs

Off-grid power supply:
set up your own power grid, e.g. in conjunction with a photovoltaic system

Modular principle

TS storage systems can be flexibly adapted to suit your application. The desired capacity can be built up 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 5, 8 or 10 battery modules. The 1-phase or 3-phase connection and the connected load determine the number of battery inverters required.
