All the use cases at a glance

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 and generation control

Active switching on and off of consumers and producers to optimize the energy balance in relation to the energy produced.

RLM Peak Shaving

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

Multi-Use

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

Charging Station Control

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

Dynamic Electricty Tariffs

The drawing of power from the grid can be automatically deferred to time windows with cheap electricity prices.

Forecast-Based Charging

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

Time-of-Use

Time-dependent use of energy features and services.

Off-Grid

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

Back-up Power

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

Feature Highlights for installers

Easy and fast commissioning

The commissioning assistant guides you step by step through the entire setup process, helping you avoid mistakes and continue exactly where you left off — even on the next day.

Reduces the risk of missing any step and is ideal for training and supporting new technicians

Strategy Setup

Choose a strategy. The EMS does the rest.
Define how your battery should behave—self-consumption optimization, peak shaving, or advanced expert strategies. Priorities, limits, and consumers are configured visually and executed automatically in real time.

Complex configurations become fast and approachable: new technicians gain confidence, while experts retain full flexibility.

Remote technician Interface

Remote monitoring and diagnostics provide full visibility into system status, parameters, and filters — with remote access to every connected device and sensor.

Fewer on-site visits, faster troubleshooting, and lower service costs lead to consistently happier customers.

Over the Air Software Updates

Choose the right time for every customer and install software updates effortlessly through a clear, dedicated interface that supports smooth planning and operation.

Control and coordinate your clients’ systems comfortably and at your own rhythm.

Battery combinability

All TESVOLT batteries working with TESVOLT Energy Manager can be combined, allowing systems to expand seamlessly later and enabling installers to extend projects with minimal additional effort.

Simple modernization of older customer installations ensures ongoing business opportunities.

EMS Licensing - no subscriptions, no renewals, no hidden costs.

Pre-installed. Ready to use. No extra steps.

All TESVOLT Energy Manager systems delivered from 1 August 2025 onwards come with a permanently pre-installed licence.

There are no recurring or ongoing licence fees. You pay once for the product—your battery storage system, including all hardware and software—and the licence remains valid for the lifetime of the device.

Unpack the device, install it, and get started.

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.
