TESVOLT energy management system

Control and monitoring made easy

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 commerce 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 Hardware

The Online Portal

The TESVOLT Energy Manager is at the heart of our energy management system. It can be integrated locally in the meter cabinet or via the TESVOLT Backup Control Box, and it controls all connected generators and consumers, records all relevant data and optimises energy flows.

  • Autonomous energy management
  • 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)

The myTESWORLD portal is simple to access using a web browser. It offers a wide range of functions for monitoring and controlling energy flows. They are available in both a free Basic version and a fee-based Pro version, corresponding to the associated areas of use.

  • Real-time dashboard
  • Overview of power consumption and generation
  • Detailed breakdown of consumption and generation
  • Energy balance
  • Metering data history
  • Energy reports and detailed meter readings (may not be used for billing purposes)

All the functions at a glance

Free Basic Version

Self-Consumption Optimisation

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

Physical Peak Shaving

Shave consumption peaks and minimise demand rate costs. The grid connection must be able to supply all loads.

Zero Feed-In

VDE FNN-certified fulfilment of grid requirements for not feeding electricity into the utility grid.

Load Control

Consumption optimisation via active connection/disconnection of consumers depending on the energy generated.

Generation Control

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

Charging Station Control1

Smart control of a single charge (set) point and central controls via the TESVOLT Energy Manager.

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

A battery inverter with a power quality function balances fluctuations in the mains voltage, thus ensuring that facilities have consistently high mains quality and therefore operate safely.


Simultaneous use of various applications (SCO & PS RLM, SCO & TOU, PS & TOU)

Charging Station Control1

Smart control of multiple charge (set) points and central controls via the TESVOLT Energy Manager.

Forecast-Based Charging

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

Semi-Off-Grid Operation

The consumers are supplied exclusively from the utility grid or entirely from their own storage systems and generators.


Time of Use

Time-dependent use of energy features and services.


Supplying a small power grid with or without connection to a public utility grid. A micro-grid consists of a battery storage system in addition to other generator systems and controllable consumers.


Back-up Power

Storage system immediately takes over the power supply in the event of a power outage.


TESVOLT’s solution for simple off-grid systems which solely consist of a photovoltaic installation and battery system.

Direct marketer interface

The PV direct marketer transmits the control signals to the PV installation via the EMS.


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

The Basic version is included in the battery storage system at no additional cost. It includes all the energy service functions listed. These can be combined under restrictions.

1. Restriction: only if PV and battery inverter each fulfill an energy service function.

2. Restriction: the customer can combine a maximum of two energy services).

The Pro version can be added to the battery storage system at an additional annual cost of EUR 3/kW (battery inverter output). It includes all of the energy service features listed below as well as the Basic version. Considering project-specific dependencies, these features can be combined and allow the simultaneous use of different energy service strategies.
