TS HV 70
lithium storage system

The all-rounder

  • Particularly low cost per kilowatt-hour stored (approx. 10 euro cents)
  • Battery voltage from 575 to 1,000 volts
  • Optimized for use with the 3-phase SMA Tripower Storage 60
  • Battery modules can be exchanged, even years down the road
  • Built to last 30 years and 8,000 full cycles
  • 1C charging speed
  • The safest cell technology


The TS HV 70 system is not only built for efficiency, it is also one of the most advanced and powerful storage systems on the market.

All the components of our storage systems are built to last 30 years and 8,000 cycles, 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 HV 70 storage system is one of the safest and most efficient products on the market.

The TS HV 70 storage system can store energy very quickly, and release it again just as quickly. With a discharge rate of 1C the storage system is optimized for professional use in commercial applications, agriculture and industry.

Areas of application

The TS HV 70 storage system is optimized 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 particularly high cost-efficiency.

Load shifting:
cut peaks in consumption and save money by reducing the size of the grid connection

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

Grid services:
regulate reactive and/or active power or frequency and offset fluctuations in the power grid

Diesel hybrid optimization:
reduce the consumption of diesel hybrid systems with this storage system

System setup

TESVOLT TS HV 70 storage systems are optimized for use with 3-phase SMA Tripower Storage 60 battery inverters and tailored to the requirements of industry and commerce, paving the way for storage solutions in the megawatt range.

Thanks to the energy management system integrated in the battery inverter and the TS HV 70’s high C-rate, a wide range of grid system services can be provided. This system opens up new economic opportunities for industry and commerce.
