Energy flows can be recorded, controlled and monitored with the innovative TESVOLT energy management system – consisting of the locally configurable TESVOLT Energy Manager and the myTESWORLD cloud 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 Manager charges the battery and shifts loads into low-tariff periods using price and generation forecasts. You reduce grid purchases and stabilise operating costs.
Optimal use of your solar or wind generation increases self-consumption and decreases dependence on the grid.
TESVOLT Energy Manager is your entry point into the future energy economy — from flexibility services to trading models and virtual power plants.
The EMS can smooth load peaks automatically, reducing demand charges and helping you avoid expensive grid connection upgrades.
You would like to get to know myTESWORLD better? Then simply register for a test account via our EMS portal and get an overview of all the functions of our energy management solution at your leisure. We’d naturally be delighted to help you if you have any questions.
It’s so simple:
Click on myTESWORLD in the EMS Portal and enter your e-mail address and a password. You will then receive a confirmation link to log in. Once you are logged in, you can test all the functions of myTESWORLD by clicking on the "Start the DEMO" button.
 | Use more energy from renewable sources and minimise feed-in. | ||
 | Shave consumption peaks and minimise demand rate costs. The grid connection must be able to supply all loads. | ||
 | VDE FNN-certified fulfilment of grid requirements for not feeding electricity into the utility grid. | ||
 | Active switching on and off of consumers and producers to optimize the energy balance in relation to the energy produced. |
| A smart way of reducing consumption peaks at 15-minute intervals and making full use of storage systems. | ||
 | Simultaneous use of various applications (e.g. SCO & PS RLM, SCO & TOU, PS & TOU) | ||
 | Smart control of multiple charge (set) points and central controls via the TESVOLT Energy Manager. | ||
The drawing of power from the grid can be automatically deferred to time windows with cheap electricity prices. |
 | Depending on the weather forecast, curtailment losses from photovoltaic installations are avoided and self-consumption is optimised. | |
 | Time-dependent use of energy features and services. | |
 | TESVOLT’s solution for simple off-grid systems which solely consist of a photovoltaic installation and battery system. | |
| Storage system immediately takes over the power supply in the event of a power outage. |
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.
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.
Remote monitoring and diagnostics provide full visibility into system status, parameters, and filters — with remote access to every connected device and sensor.
Choose the right time for every customer and install software updates effortlessly through a clear, dedicated interface that supports smooth planning and operation.
All TESVOLT batteries can be combined, allowing systems to expand seamlessly later and enabling installers to extend projects with minimal additional effort.
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.
