Lithium storage system TPS-E

The all-rounder for grid services and industry

  • High energy density – up to 40% cheaper than the previous model TPS 1.0 with doubled capacity and the same footprint
  • Exceptional efficiency thanks to new eco-cooling concept and intelligent operation management
  • Flexible configuration and expansion possible even years later
  • Low maintenance and service costs thanks to optimal remote maintenance
  • Long lifespan designed for a life cycle of 30 years
  • Extremely resilient – can be used in environments with temperatures from -25 to +50°C
  • Samsung SDI high-quality cells with the highest safety standards and long lifespan

Other Benefits

  • Can be used up to a rated voltage of 1,300 V DC
  • Black start capable
  • 100% DoD
  • High failure safety through master/slave systems (if the master fails, the slave will assume its role)
  • AI-ready – prepared for automated AI fault diagnostics
  • Three different container sizes available (20 ft, 40 ft or 45 ft)
  • Easy to transport on water and land thanks to ISO containers
  • Optimised for use with SMA Sunny Central Storage System

Areas of application

The TS HV 70 storage system is optimised for particularly demanding operations in commercial enterprises with storage requirements in excess of 30 kilowatt hours. The investment costs for the system and the price per kWh stored remain low thanks to the system’s exceptional cost-efficiency.

Increase self-consumption:

Use more of the power you generate
and save electricity costs

Peak load shaving:

Cap your consumption peaks and save money
thanks to reduced grid connection

Charging station infrastructure:

Solve the problems of the future and combine peak load shaving,
self-consumption and grid services applications

Diesel hybrid optimisation:

Use the system to optimise your diesel hybrid consumption

Grid services:

Manage frequency, reactive power and active power
and balance utility grid fluctuations

Time of use:

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