Overview of all application areas

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.

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

Physical Peak Shaving
Shave consumption peaks and minimise demand rate costs.

Simultaneous use of two applications (SCO & PS, ToU & PS, ToU & SCO).

Time of Use
Time-dependent use of energy features and services.

Generation Control
Consumption optimisation via active connection/disconnection of generators depending on the energy generated in grid operation.

Ancillary Services
Remote control of active and reactive power.

TESVOLT solutions optionally adjust the power grid and balance generation and consumption peaks to keep the diesel generator in optimal operation, minimizing diesel costs.

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

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

System setup

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

Thanks to the energy management system integrated in the Inverter Manager and the TS HV 70’s high C-rate, it allows for a wide range of grid system services. This system opens up new economic opportunities for industry and trade.
