TESVOLT energy management system

Control and monitoring made easy

All energy flows can be recorded, controlled and monitored with the innovative TESVOLT energy management system – consisting of the TESVOLT Energy Manager and the myTESWORLD portal. By setting individual operational strategies, you can combine a wide variety of applications and thus perfectly adapt the system to the needs of trade and industry.

The TESVOLT energy management system is available both as a free Basic version and as a fee-based Pro version with valuable additional functions, such as minute-by-minute data evaluation for even greater transparency, or the multi-use function.

The system is only available at present in combination with the TS-I HV 80.

TESVOLT Energy Manager

  • Data acquisition and optimised energy flows
  • Generation, load and storage system control
  • Configuration through a user interface with different views for different user groups
  • Local integration in the meter cabinet or in the TESVOLT Backup Control Box (function-tested and pre-wired)

All the functions at a glance

Free Basic Version

Self-Consumption Optimisation

Use more energy from renewable sources and minimise feed-in


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


Physical Peak Shaving

Shave consumption peaks and cut demand rate costs

Back-up Power

The storage system immediately takes over the power supply in the event of a power outage

Zero Feed-In

Fulfils the normative guidelines (Germany) stipulating that no power can be fed into the utility grid

Load Control

Actively switch consumers on and off depending on generation and consumption (see compatibility list)

Charging Station Control1

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

Fee-Based Pro Version

RLM Peak Shaving

A smart way of reducing consumption peaks at 15-minute intervals and making full use of storage systems

Power Quality

Keep the utility grid in a constant, correct frequency range. Harmonics are counterbalanced dynamically, improving the power quality in the system



Simultaneous use of two applications (SCO & PS)

Charging Station Control1

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

Forecast-Based Charging

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

Semi-Off-Grid Operation

Consumers are fed either from the grid alone, or else up to 100% from a storage system and renewable energy installations. In-house energy sources are never connected to the public utility grid.


1) Additional costs for project planing a incurred for more than one charging station

1) Only project-based, additional costs for project planning are incurred, 2) Additional costs for project planning are incurred for more than one charging station
