Our newly designed TS HV 30-80 battery storage systems replace the TS HV 70 E with immediate effect. They set a completely new standard in independent energy supply for industry, commerce and agriculture. Performance, economic efficiency and compact dimensions for every energy content variant. And now the modular system design is even more flexible, enabling customised adaptation for every requirement to make our new benchmark product absolutely future-proof.
The 2-in-1 hybrid storage solution with the GoodWe hybrid inverter and integrated back-up function is particularly suitable for connecting new photovoltaic systems directly to the inverter and allows consumers to be supplied reliably even in the event of a grid failure. At the same time, the system is extremely efficient to use.
The TS-I HV 80 E with integrated TESVOLT inverter and innovative energy management system impresses users with its extremely high energy density and low investment costs. With its extensive range of applications – from multi-use capability to back-up power, self-consumption optimisation, peak shaving as well as consumer and generator control – it is the optimal system for a wide range of requirements in both off-grid and on-grid use. And its power quality technology even brings sustainable quality improvement to the local utility grid.
The TS-I HV 100 E impresses users with its outstanding performance – despite low space requirements – as well as the attractive investment costs. Equipped with the integrated TESVOLT inverter as well as an innovative energy management system, it’s the right system for virtually any application – including the multi-use combination of self-consumption optimisation and peak shaving. Here too, our power quality technology brings sustainable improvement to power quality to protect machines and plants.
TESVOLT stands for innovation and the highest quality standards. Thanks to technological advances and sustainable developments, we are currently introducing a new generation of storage systems that are even more efficient, durable and powerful.
Our goal is to stay at the cutting edge of innovation and offer you products that secure the value and trust you place in TESVOLT in the long term. With this further development, we are setting standards for the future of energy storage – and remain your reliable partner for advanced solutions.

Yes, this is possible if the system is operated with our TESVOLT Energy Manager. These systems can be expanded in terms of energy and power using our TESVOLT FORTON or TESVOLT TAYTAN . They are then ‘grouped’ and centrally controlled by the TESVOLT Energy Manager. Software version 3.2 of the TESVOLT Energy Manager is required.
You can find more information about the TESVOLT Energy Manager here .
For the TS HV 30-80 E product series, expansion using TESVOLT TAYTAN and TESVOLT FORTON is also possible when using the SMA energy management system.
Our stackable TESVOLT TAYTAN solution, safely manufactured in Germany, offers you the highest safety standards, high performance and a wide range of installation options. Home or commercial use, indoor or covered outdoor installation and a large number of configuration sizes allow for maximum flexibility. Combined with classic applications such as self-consumption optimisation, peak load capping or multi-use, the TESVOLT TAYTAN is the ideal alternative to our standard E-series products.
Our TESVOLT FORTON is our new ‘outdoor economic miracle’ and offers you flexible, future-proof solutions for trade and industry. With classic applications such as self-consumption optimisation, peak load capping or the use of dynamic electricity tariffs, the TESVOLT FORTON offers a very good alternative to the standard products and container solutions of the E-series thanks to its high efficiency and flexibility. In combination with our intelligent trading software from TESVOLT ENERGY, the TESVOLT FORTON also enables profitable access to energy trading.
Our TESVOL TALLON battery container is the ideal solution for electricity trading, control power or grid stability – powerful, safe and economical. Whether as a stand-alone battery park connected to the grid, for peak load capping in industry and commerce, or as part of a hybrid power plant – our system adapts flexibly to any application. An excellent alternative to the largest E-series container solutions.
