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.

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.

Benefits of the energy management system for installers

System structure

1. Energy management system

1. The energy management system (EMS) is the central control instrument for the overall system. It monitors, controls and optimises the energy flow between the various components to ensure the efficient use of available resources. Thanks to smart interconnection and data analysis, the EMS plays a key role in boosting energy efficiency and reducing energy costs.

2. Utility grid

The utility grid acts as an additional back-up resource within the system for times when renewable energy production is low. In combination with a battery storage system, it actively relieves the pressure on the public utility grid and provides a reliable supply of electricity, particularly at peak load times.

3. Energy resources

The wide range of energy resources within the system design, such as photovoltaics and wind power, generate the required electricity, which the battery storage system stores without environmental impact.

4. Portal

For efficient and transparent management of the energy balance and to ensure a customised energy supply, the portal allows users to monitor energy flows, track the system status and analyse energy consumers.

5. Battery storage system and inverter

The battery storage system is a key system component for the storage of surplus electrical energy. It allows load compensation, ensures security of supply and helps reduce energy costs. In combination with an inverter, which handles the flexible conversion of direct current (DC) into alternating current (AC) and vice versa, this ensures an efficient supply of energy. The inverter also responds to grid fluctuations immediately and delivers the required power quality. The energy flow is coordinated and the charging and discharging processes of the battery storage system are controlled. This optimises the use of stored energy to allow the integration of renewable energy sources as well as a wide range of applications.

6. Heat pump

The heat pump uses ambient heat for efficient heating and cooling of buildings. It integrates seamlessly into the energy management system and helps reduce energy consumption. In combination with renewable energy and the battery storage system, the heat pump allows sustainable and environmentally friendly temperature regulation.

7. Consumers

Every consumer has their own individual energy requirements. All system components are tailored to these requirements and work together to ensure a sustainable and cost-efficient supply.

8. Charging station

The charging station allows charging of electric vehicles and acts as a complement to the overall system. Integration into the energy management system allows the charging process to be monitored and controlled to ensure the efficient use of available energy.
