More cyber security through proprietary battery park control
“Today, many battery containers hardly differ from one another, and almost all of them come from Asia. We also source them there, selecting robust, high-performance systems – but then we do something differently from many others: we integrate our own battery park control system, which provides significantly higher protection against cyber attacks,” explains Simon Schandert, CTO and co-founder of TESVOLT. “This control system incorporates several years of experience gained from numerous battery park projects.”
All data connections of the TESVOLT Energy Controller EZA pro L to the internet, for example, are exclusively routed via dedicated VPN tunnels to prevent external manipulation. In addition, outbound data connections are designed as one-way links only, and the plant controller is protected against direct internet access by dedicated hardware.
European inverters as protection against cyber threats
“The European Commission is currently considering excluding manufacturers of Chinese inverters from the European market in order to better protect critical infrastructure against cyber threats,” Schandert continues. “We have long recognised the concrete risks posed by inverters from certain manufacturers. This is why our storage systems are compatible with European inverters. Tallon, for example, works with a German inverter from SMA and a Spanish inverter from Power Electronics.”
Unique on the market: one-stop shop model for municipal utilities
“What no one else in the energy storage market currently offers: we do not simply deliver a battery container to municipal utilities, but accompany them along the entire path to a profitable battery park – including operation,” says Sebastian Jänig, Head of Utility-Scale Storage Projects at TESVOLT. “That may sound unspectacular, but no one else is doing this today. In concrete terms, this means that we provide battery containers tested by us with proprietary software, as well as project planning, installation, operation, monitoring and power trading. All components are coordinated with one another, everything runs digitally – and if digital support is not sufficient, our technical experts provide on-site assistance.”
Through its subsidiary TESVOLT Energy, the company also offers energy trading on the exchange. TESVOLT Energy cooperates with three of Germany’s leading power traders and puts them in competition with one another in order to achieve even higher revenues for municipal utility and commercial customers.
Tallon large-scale storage system for greater project flexibility
Thanks to its modular concept, the Tallon storage container provides greater flexibility in planning, operation and later expansion of storage systems. Customers can choose between one, two or multiple DC outputs per container and flexibly distribute battery capacity across several inverters. This allows storage capacity to be optimally matched to the desired power output, making charging and discharging processes more efficient. Storage capacity can also be expanded retrospectively.
Due to its very high level of fire protection, Tallon large-scale storage systems can be installed with a spacing of just 10 cm between units. The battery modules use heavy-metal-free LFP technology. Owing to its long service life, TESVOLT offers an above-average warranty of 15 years for Tallon, compared with the market standard of ten years.

Field Tests completed: New Tesvolt Commercial Storage System Generates High Revenues in Energy Trading
Field Tests completed: New Tesvolt Commercial Storage System Generates High Revenues in Energy Trading
Energy’s Virtual Storage Power Plant is Growing
Wittenberg/Germany, 25 November 2025 – The new commercial energy storage system Tesvolt Forton has proven itself in the field. This has been reported by battery storage provider Tesvolt and its subsidiary Tesvolt Energy. Over several months, the outdoor storage system was tested in ten different customer projects. Those storage systems used exclusively for energy trading are already generating monthly revenues in the four- to five-figure range. Tesvolt Forton has also demonstrated its effectiveness in classic applications such as optimising self-consumption and peak shaving.

Lessons learned
“Field tests are extremely important – especially when using battery storage systems for energy trading as this significantly raises the requirements for hardware, software and technical support,” says Leonard Friese, Product Manager at Tesvolt. “We learned a lot during the field tests. At first, there were several technical hurdles, then only occasional minor issues – and finally the moment came when everything ran smoothly on a permanent basis.”
Early Coordination with Grid Operators is Key
“The field test phase helped us optimise new project workflows and internal processes. Initially, it took several days to digitally integrate a new storage project into our virtual power plant together with the traders. Now it’s just a few steps, usually completed within half a day,” explains Juri von Wilcken, Product Manager at Tesvolt Energy. The start-up aggregates commercial energy storage systems into a virtual power plant, enabling even smaller battery systems to participate in energy trading on the electricity exchange. “We also learned how essential it is to engage with the relevant grid operators already during the early project initiation phase, to ensure that the start of commercial operation is not unnecessarily delayed.”
Storage Systems in Energy Trading Generate High Revenues
“Energy trading is creating a gold rush atmosphere in the energy storage industry right now. But I wanted to try it out first before offering the Forton and the business model to my customers. Now I know: it works. The storage systems run smoothly and generate the forecasted revenues. This means they will pay for themselves in about five to six years,” says Johannes Mitterreiter, Managing Director of the electrical engineering company Reichbrandstätter in Southern Germany. “I have four Forton units on my company premises. When customers see them and I show them the revenues, they want a piece of the pie too – they want to join in energy trading.”
Until now, operators of commercial battery storage systems have had very limited opportunities to find a trader willing to market their smaller storage capacities on the power exchange. Tesvolt Energy aggregates these systems and connects them to the grid as part of a pooled asset, enabling their capacity to be marketed by three of Germany’s most renowned energy traders. By introducing competition between the traders, the start-up ensures particularly attractive returns and reduced risk for customers. Participation is possible for anyone with a grid connection of at least 50 kW and a battery storage system starting from 50 kW.
15-Year Performance Guarantee
“Commercial storage has never been this economical. Technically, this is only possible with a battery storage system that is extremely robust – capable of being charged and discharged several times a day over many years,” explains Simon Schandert, CTO and Co-Founder of Tesvolt. “Tesvolt Energy’s intelligent software also ensures that the storage system is operated as profitably as possible while being as gentle as necessary.”
Virtual Storage Power Plant is Growing
“Since the field tests were completed, we’ve been receiving even more orders from customers who want to use Forton for energy trading. We are therefore onboarding more and more storage systems into our virtual power plant,” reports von Wilcken. “Two-thirds of all orders are for Forton units intended for trading, while one-third are for classic applications such as optimising self-consumption and peak shaving – which remain highly profitable.”

First Electric Cable Excavator Vessel Runs on TESVOLT OCEAN Batteries
First Electric Cable Excavator Vessel Runs on TESVOLT OCEAN Batteries
Work vessel converted to fully emission-free operation
Lübeck/Germany, Sliedrecht/Netherlands, 19 November 2025 – The first fully emission-free cable excavator vessel is now operating in the Netherlands. It is powered entirely by TESVOLT OCEAN batteries, which are charged using hydrogen fuel cells. The vessel belongs to the hydraulic engineering company Van den Herik and has been recognised by the independent Green Award Foundation with the Green Award Gold for its outstanding contribution to sustainable innovation. The project successfully converted the high-energy-demand work vessel Prins 6 into the zero-emission vessel Prins ZEs, despite the initial absence of charging infrastructure – saving substantial amounts of CO₂ in the process.
Press pictures: https://www.tesvolt-ocean.com/en/press/first-electric-cable-excavator-vessel-runs-on-tesvolt-ocean-batteries.html
Work vessel with high energy demand
As a working vessel, the Prins ZEs requires large amounts of energy and covers long distances every day. The installed Compass Core battery modules from the Kaptein series therefore provide a storage capacity of nearly 2 MWh. When fully discharged, they can be completely recharged within 12 hours using the fuel cell generator – after that, the Prins ZEs can operate and work electrically for an entire working day.
Charging speed and space efficiency were key
“We needed batteries that could charge large amounts of energy quickly and take up minimal space on board,” says Isolde Struijk, Managing Director of Van den Herik in Sliedrecht, near Rotterdam. “When the crane begins operation, it creates high load peaks, so it was equally important for the battery system to be exceptionally robust and maintain stable performance under stress.”
Strong and lightweight – ideal for retrofit applications
“We designed our battery modules to make retrofitting electric drives on vessels as simple as possible,” explains Michael Miebach, Key Account Manager at TESVOLT OCEAN. “Despite their low weight, the modules offer very high energy density: the nearly 2 MWh of total storage capacity requires only about 0,6 m × 3,6 metres of space with a total height of ca. 1,8 metres. We’re thrilled that the Prins ZEs is operating with our battery system. It’s a true flagship project proving that clean shipping is achievable even for vessels with demanding power requirements.”
The Compass Core battery system is also designed to be cooled by ambient air, simplifying installation and reducing maintenance costs.
Hydrogen mini power plant
Since there is currently no charging infrastructure along inland waterways, Van den Herik developed its own compact hydrogen fuel cell generator. Measuring only 3 × 2.6 × 2.5 metres, it can produce up to 3,600 kWh of electricity per day – enough to continuously power a residential neighbourhood of around 400 households when combined with a battery storage system. The generator is installed onshore, next to a trailer containing hydrogen tanks. Inside the fuel cell, hydrogen is converted into electricity, which is then transferred to the onboard batteries.
A pioneer in hydraulic engineering
The Dutch authority Rijkswaterstaat, responsible for the construction and maintenance of roads and waterways, praised the Prins ZEs as a pioneering project. Roger Mol, Head of Sustainability and Procurement at Rijkswaterstaat, commented: “Projects like the Prins ZEs show that decarbonisation in hydraulic engineering is possible when government and industry take shared responsibility.”
Rijkswaterstaat supports so-called “front-runner projects” (“koploperprojecten”) – initiatives that put new sustainable solutions into practice in collaboration with industry. The project was realised through close cooperation between Van den Herik, TESVOLT OCEAN, system integrator Verhoef Elektrotechniek, and shipyard Kooiman Marine Group.

TESVOLT OCEAN battery system receives type approval for maritime use
PRESS RELEASE
TESVOLT OCEAN battery system receives type approval for maritime use
RINA type approval confirms market readiness of Kaptein Compass Core battery
Lübeck/Germany, September 17, 2025 – The “Kaptein NMC Compass Core” battery system from Lübeck-based manufacturer TESVOLT OCEAN has been approved by the multinational engineering consultancy, inspection and certification group RINA for use in inland and seagoing vessels. The battery successfully passed all functional and stress tests, demonstrating its safety and robustness. Developed specifically as an e-drive solution for smaller vessels, the Compass Core is also suitable for retrofitting on ships with very limited onboard space. At just 5.9 kg per kWh, the module is significantly lighter than conventional marine batteries and also charges exceptionally quickly. The Compass Core has been optimised for ship projects with very limited budgets.
Press images: https://www.tesvolt-ocean.com/en/press/tesvolt-ocean-battery-system-receives-approval-for-maritime-use.html
Exceptional safety through integrated protection mechanisms
“The Kaptein Compass Core battery module passed all RINA tests for type approval certification of lithium battery systems,” reports Patrizio Di Francesco, North Europe Special Projects Manager and Principal Engineer at RINA Germany in Hamburg. “TESVOLT OCEAN’s protection concepts are carefully integrated and make a vital contribution to onboard system safety. In the event of critical battery temperatures, a multi-stage protection system is activated. The module has also proven to be extremely robust.”
Fast-charging and lightweight
“RINA applies high standards and works with more than 100 flag administrations worldwide, making it highly experienced in the technical evaluation of ship components. We are therefore especially pleased that the Kaptein Compass Core has received approval for inland and seagoing vessels from RINA and can now, quite literally, set sail,” says Frank Richter, Portfolio Manager at TESVOLT OCEAN. “In fact, demand for safe, reliable battery systems for clean marine propulsion is growing rapidly, as more and more ports are denying entry to vessels without clean propulsion. While there are many battery systems on the market, they are all heavier than the Kaptein Compass Core and most charge very slowly.” The Kaptein Compass Core offers a 4 C rate – the highest C-rate currently available in the maritime industry.
Optimised for vessels with limited space
Like all TESVOLT OCEAN modules, the Compass Core battery modules can be mounted individually and at any angle within a ship. Measuring 60.5 cm in length and 14.9 cm in height, they fit into almost any niche. They can also be installed directly on the floor; being vibration-resistant, they can be walked on once installed. Thanks to their low weight of just 86 kg, the Compass Core modules can be carried by two people and installed without the need for a crane – even in hard-to-access areas of the ship. The system is air-cooled, which further simplifies installation and reduces maintenance costs.

Long wait to connect large storage systems to the grid, unlike smaller systems
Long wait to connect large storage systems to the grid, unlike smaller systems
Combined power plant consisting of many small commercial storage systems makes the electricity grid more flexible
Berlin, Wittenberg/Germany, 7 July 2025 – Distribution grid operators are receiving a large number of requests to connect large-scale energy storage systems to the medium- and high-voltage grid. This has been published by Bayernwerk Netz, Bavaria’s largest distribution system operator, and Mitnetz Strom. Due to the necessary grid expansion measures, the waiting period for applicants is usually at least five years. Start-up TESVOLT ENERGY has found a solution that can quickly connect battery storage solutions to the utility grid. It gives commerce and industry – which usually already have a sufficiently large connection to the low-voltage grid – the previously lacking incentive to connect smaller energy storage systems of 100 kWh or more to the utility grid.
Press images: https://www.tesvolt.com/en/press/long-wait-to-connect-large-storage-systems-to-the-grid-unlike-smaller-systems.html
Influx of applications for grid connections from large-scale battery storage systems
“The number of applicants who want to connect large-scale storage systems to the utility grid is continuing to rise. This is no different to the other large distribution system operators,” reports Stephan Kilz, Head of Generation Plants for Individual Customers at Mitnetz Strom, one of the largest distribution system operators in eastern Germany. “Bringing more flexibility to the utility grid using battery storage systems is important. However, this usually requires grid expansion measures, so it often takes several years before a new large-scale storage system or battery park can be connected to the utility grid.”
Bayernwerk Netz, Bavaria’s largest grid operator, is also reporting the very high number of connection requests for large-scale storage systems on its homepage. For the medium- and high-voltage grid, the capacity for grid connections has already been exhausted to such an extent that it will only be possible to connect storage systems of more than 300 kW in five years’ time or more.
Until now, there has been no incentive for smaller battery storage systems to connect to the utility grid
“We urgently need much more storage capacity in the electricity grid so that renewable energy suppliers do not have to be limited in the event of strong sunlight and strong wind. Instead of building a mind-boggling number of new gas-fired power plants to make the electricity grid more flexible, we should focus on climate-friendly solutions,” says Sebastian Kratz, Managing Director of TESVOLT ENERGY. “Commercial and industrial companies have enormous potential for bringing urgently needed flexibility to the utility grid with battery storage systems. So far, other than the big battery park operators, they haven’t had the opportunity to find a good trader that trades their small storage capacities on the exchange. They have therefore been excluded from energy trading.”
Network of smaller storage systems makes lucrative energy trading possible
TESVOLT ENERGY is enabling commerce and industry to engage in lucrative front-of-the-meter energy trading for the first time. The company integrates battery storage systems of 100 kWh or more into a pool. In doing so, many smaller storage systems form a virtual power plant, whose capacity is traded by renowned traders Enspired, Entrix and The Mobility House. The prerequisite is that commercial enterprises have a grid connection point with an output of at least 50 kW. On-site planning, installation and maintenance of battery storage systems are handled by specialist partners trained and certified by TESVOLT.
A one-of-a-kind first: trader competition for higher revenue
“We bring our traders into competition with each other. The energy trader whose trades achieve the highest revenues with the least intensive operation of the storage systems gets to manage the most battery systems in our pool,” explains Anshoo Pandey, who is heading the new company together with Sebastian Kratz. “This business model is unique on the market so far. This allows us to generate higher revenues for our customers.” Software developed by TESVOLT ENERGY ensures careful operation of the battery storage systems. TESVOLT storage systems that use this software therefore also have a 15-year performance guarantee. This far exceeds the usual market performance guarantees.
Collaboration with grid operators
“We are also prepared to respond to the requirements of grid operators and operate storage systems in a grid-neutral manner or in a grid-supporting manner at specific times – i.e. not feeding electricity from the storage systems into the utility grid when renewables are supplying a lot of electricity. Or using our storage systems to absorb excess electricity from the utility grid,” says Kratz. “Using our software and redispatch interface, we can implement this technically straight away and are already talking to grid operators about specific timescales and restrictions for charging and discharging our battery storage systems. After all, we are all driven by the goal of getting as much renewable electricity as possible into the utility grid. Climate protection is not a luxury item that we cannot afford right now. In the current political debate about gas and other fossil fuels, people often ignore that the costs of climate change are enormous.”
About TESVOLT ENERGY
TESVOLT ENERGY GmbH is a software start-up based in Berlin, Germany. Intelligent TESVOLT ENERGY software enables front-of-the-meter energy trading with very high revenues and a long lifespan for battery storage systems starting at just 100 kWh.

TESVOLT OCEAN expands battery system portfolio for clean shipping
TESVOLT OCEAN expands battery system portfolio for clean shipping
Exhibitor at Electric & Hybrid Marine Expo Europe 2025
Lübeck, Amsterdam, 16 June 2025 – TESVOLT OCEAN, manufacturer of high-performance battery storage solutions for inland and maritime shipping, is expanding its product portfolio. The German Norwegian company will be presenting its two new battery systems ‘Kaptein NMC Compass’ and ‘Kaptein NMC Compass Core’ for the first time at the Electric & Hybrid trade fair in Amsterdam from 24 to 26 June. The Compass is particularly light and compact. The Compass Core is just as compact but is also optimised for price-sensitive projects. This complements the manufacturer’s Kaptein series, which was launched last autumn with the high-performance ‘Kaptein NMC Navigator’. Thanks to their disruptive technology, all three storage solutions are characterised by further unique selling points.
Press Images: https://www.tesvolt-ocean.com/de/presse/tesvolt-ocean-erweitert-batteriesystem-portfolio-fuer-saubere-schifffahrt.html
Optimised for smaller vessels and retrofits
‘We are continuously developing our battery systems – based on customer feedback and practical requirements,’ explains Kilian Hoffmann, CCO at TESVOLT OCEAN. ‘Together, Navigator, Compass Core and Compass cover a wide range of requirements – from high-performance propulsion to retrofitting ships with very limited installation space.’
With a length of 60.5 cm and a height of 14.9 cm, the new storage solutions fit into almost any niche on a ship. And at 5 and 5.9 kg per kWh respectively, they are significantly lighter than other standard batteries on the market, which weigh at least 7 kg per kWh.
Like the Navigator battery modules, the new Compass and Compass Core battery modules can be installed individually and at any angle in the ship. The vibration-resistant battery modules can also be installed on the floor and then walked on. Thanks to their low weight of 75 or 86 kg, the battery modules can be carried by two people and installed in areas of the ship that are difficult to access. A crane is therefore not required for installation. The battery system is designed so that cooling by the ambient air is sufficient – this also simplifies installation and reduces maintenance costs.
Fast charging with 4 C
‘Many ship owners find the charging times of commercially available batteries too long. Most marine-approved batteries don’t even have a continuous C-rate of 2 C,’ reports Kent Thoresen, CTO of TESVOLT OCEAN. ‘At 4 C, our entire Kaptein series offers the highest continuous C-rate available in the maritime industry to date. For ship owners, this means significantly shorter loading times and therefore less downtime in harbour. This is important, because only a moving ship earns money.’
Compass Core for particularly price-sensitive projects
The Compass Core was developed for ship projects where the budget is particularly limited. At 5.9 kg per kWh, it is slightly heavier than the Compass and Navigator models, but correspondingly cheaper. The battery system is due to be launched on the market in the 3rd quarter of this year.
Compass for particularly weight-sensitive projects
‘With its 5 kg per kWh, the Compass is our absolute lightweight hero. It is therefore suitable for all ship projects in which the weight of the battery system plays a particularly important role,’ Hoffmann continues. ‘The Navigator, on the other hand, still has the highest performance and therefore the longest range.’ The Compass should be available at the beginning of next year.
Significant demand for electric drives
‘The demand for sophisticated battery systems for clean ship propulsion systems is huge, which was also very clear at the Maritime Industry trade fair in Gorinchem,’ says Michael Miebach, Key Account Manager at TESVOLT OCEAN. This is not surprising, as more and more harbours are no longer allowing ships without clean propulsion to enter. ‘Once again, we have realised that our Kaptein series offers real solutions to a whole range of problems that operators currently face when powering their ships.’

“With larger battery systems in particular, there is a risk that they will simply be switched off from other countries – e.g. due to political conflicts. This makes it all the more important at the moment that our energy provider’s energy storage systems are as secure as possible against cyber attacks,” explains Daniel Hannemann, CEO and co-founder at TESVOLT. “Our intelligent battery control system is designed to support cybersecurity.” Storing system data on servers at locations in Germany also ensures greater protection against cyber attacks.
Local partner for low downtime
“We hear repeatedly from public utilities and EPCs that they feel stranded by Chinese manufacturers in the event of technical problems. But the longer the battery systems are down for, the greater the financial loss for the operator,” reports Sebastian Jänig, Key Account Manager for utilities at TESVOLT Projects. “In contrast, we provide public utilities with everything from a single source: a particularly high-performance large-scale storage system and our team of experts for large-scale projects, which not only builds the battery parks but also monitors them down to cell level, carries out maintenance and is on site to help the public utilities in the event of any problems.” This, together with the specially developed TESVOLT Energy Controller Pro plant control system and integrated EZA controller, means battery parks can be run profitably and with very low downtime.
Making large-scale storage systems more secure and more economical
“Samsung has by far the most experience with large storage system projects on the market. This is also evident in the battery storage systems: they really suit the needs of the system operators,” continues Jänig. “As an example, Samsung is offering a unique solution to prevent battery fires. Its EDI system, short for Enhanced Direct Injection System, is an active anti-propagation system that detects overheating at the cell level and stops it automatically by injecting a cooling agent into the affected battery module.” Samsung also uses long-lasting and high-performance NCA battery cells. Very quiet cooling units result in a low noise level of only 65 decibels (dBA).
“Supplying an outstanding storage system is no longer enough these days. In order to achieve good profitability over the entire lifespan, it is important that large storage systems have the lowest possible downtime,” reports Dirk Kaisers, ESS Director at Samsung SDI. With its intelligent EZA controller, TESVOLT looks deep into the storage systems, right down to the cell level and manages them in a way that is profitable. That ensures that the large storage systems are more secure and more economical than most others.
Exceptional guarantees
The new SBB 1.5 battery container will be launched on the market with a guarantee of up to 20 years and a flexible performance guarantee. The round-trip efficiency is guaranteed to be higher than 95%, and the annual availability guarantee is at least 97%.
“Project lead times are usually around one year. The SBB 1.5 can therefore be ordered immediately, with delivery expected in the second quarter of next year,” explains Hannemann.

TESVOLT presents new stackable domestic and commercial storage system
Press release
TESVOLT presents new stackable domestic and commercial storage system
“Made in Europe” funding bonus for the new storage system
Wittenberg/Germany, 13 May 2025 – TESVOLT, a leading European full-service provider of innovative energy storage system solutions for commerce and industry, presented its new battery storage solution TESVOLT TAYTAN at the ees Europe trade fair in Munich. The system consists of battery modules that simply plug into each other – with no external cables. Between three and ten modules can be stacked, depending on the desired storage capacity. The battery modules for the new energy storage system are manufactured by TESVOLT itself in its new gigafactory in Wittenberg. This means that in future, project planners who use the TESVOLT TAYTAN can apply for the “Made in Europe” funding bonus. The battery system is designed to work with different inverters, while built-in Infineon chips protect it against cyber attacks. A 12-year performance guarantee ensures investment security.

Produced in Germany
‘Although the new storage system is produced in Germany, the pricing is in the same ballpark as comparable Chinese storage systems. We can do this because our new gigafactory in Wittenberg enables high-volume production with the sophisticated manufacturing processes we have developed’, explains Simon Schandert, CTO and co-founder of TESVOLT AG. ’One major advantage we have over Chinese storage system providers is that we offer on-site service and we also have all the spare parts on hand in our Wittenberg facility. We never leave our specialist partners hanging when problems arise.’
More funding for “Made in Europe”
In Austria, projects with battery storage systems manufactured in Europe will receive up to 20% more funding starting 23 June. This is intended to boost Europe as an industrial hub. ’We expect other European countries to follow suit,’ added Schandert.
Protection against cyberattacks
‘These days it is particularly important that battery storage systems are safe from cyber attacks. Batteries are considered critical infrastructure, but unfortunately, the risk of battery systems simply being switched off remotely or third parties gaining access to sensitive data is very real in the current political situation,’ says Daniel Hannemann, CEO and Co-founder of TESVOLT. ‘That’s why we use Infineon chips, which offer the highest security against cyber attacks on the market.’
Fully modular for smaller commercial operations and residential construction
Each battery module has a storage capacity of 6.25 kWh. The TESVOLT TAYTAN starts at three modules, which equates to a total capacity of 18.75 kWh. A maximum of 10 modules can be stacked on top of each other, which means the new storage system can reach a total capacity of 62.5 kWh. Up to four battery storage systems can be operated in parallel via an inverter.
Passive cooling
A further advantage is that the new battery storage system doesn’t require an active cooling system. The battery modules release their heat to the metal casing, so they are cooled by the ambient temperature. The TESVOLT TAYTAN can also be operated without an active heating system. The storage system can be operated at ambient temperatures of -20 to 50 degrees and is suitable for outdoor use.
The TESVOLT TAYTAN has an exceptionally robust design, and its metal casing meets the requirements of IP55, a high degree of protection. The LFP cells are particularly safe and the intelligent battery management system ensures high performance and safety. The storage system works with selected AC-based inverters and hybrid inverters from a range of manufacturers. Production is scheduled to start later this year. In the medium term, the battery storage system can then be used for lucrative energy trading.

Solution for several problems in the e-propulsion of ships
‘We are very happy that we got the contract and are now authorised to distribute TESVOLT OCEAN’s battery systems exclusively in the Benelux. Their energy storage systems are a perfect fit for Verhoef and currently outshine all other systems,’ reports Edwin Naaktgeboren, General Manager of Verhoef. ’The Kaptein series, for example, offers a real solution to a whole range of problems that operators currently face when powering their ships.’
Disruptive battery technology
The battery modules of the modular Kaptein series can be installed individually and at any angle of inclination wherever they fit in the ship. The vibration-resistant storage modules can also be installed on the floor and then walked on. Until now, there has often not been enough space in ships for battery storage systems with sufficient capacity. Thanks to its disruptive technology, the power storage system is characterised by further unique selling points: with a particularly lightweight design, high energy density and a continuous C-rate of 4 C, the Kaptein technology enables the fastest charging times in port. The series was developed for demanding maritime applications in the retrofit and new build sectors.
Milestone for TESVOLT OCEAN

TESVOLT presents new “economic miracle” battery storage system with high-temperature cells
PRESS RELEASE
TESVOLT presents new “economic miracle” battery storage system with high-temperature cells
Outdoor commercial storage systems for lucrative energy trading
Wittenberg, Germany, 25 March 2025 – TESVOLT, a leading European full-service provider of innovative energy storage system solutions for commerce and industry, presents its new outdoor battery storage system solution TESVOLT Forton at the ees Europe trade fair in Munich from 7 to 9 May. It is the company’s first system to use high-temperature cells based on LFP technology, doesn’t require liquid cooling and paves the way for profitable energy trading for commerce and industry. A performance guarantee of 15 years at two full cycles per day ensures a safe investment. Commercial enterprises need nothing more than a grid connection point with an output of at least 50 kW to use the battery system for highly lucrative energy trading.
Press images and product data sheet:
Very fast return on investment
“Commerce and industry want a very fast return on investment. With our new battery system, the investment usually pays off after just a few years if it takes part in energy trading,” explains Simon Schandert, Co-Founder and CTO of TESVOLT AG. “There’s a good reason we call it an ‘economic miracle’ – it has never been so economical to operate a commercial storage system. In technical terms, you can only achieve this with a highly robust battery storage system, one that can be charged and discharged several times a day over many years.”
High-temperature cells in battery storage systems for the first time
To make the new, scalable battery system as resilient and durable as possible, TESVOLT is using high-temperature cells for the first time. “These cells require less cooling than commercially available LFP cells. At the same time, they have an even longer lifespan,” Schandert continues. “Another special feature is that it doesn’t require liquid cooling. This saves the customer half-yearly maintenance, and any service work can also be carried out by installers who are not certified for handling environmentally hazardous substances – as these are contained in most coolants.”
Depending on the desired total storage capacity, up to 16 of the new 92 kW storage systems are interconnected on site, enabling them to achieve up to 1.5 MW.
Enabling energy trading for commerce and industry
With the new TESVOLT Forton and together with its new spin-off TESVOLT Energy, TESVOLT AG is offering commerce and industry the opportunity to participate in energy trading and reap profits at last. Until now, it has been very difficult for operators of commercial storage systems to find a trader to trade their smaller storage capacities on the electricity exchange, or they have only been able to take part on less lucrative terms. TESVOLT Energy is changing this by adding battery storage systems to a pool, as the numerous smaller storage systems are only of interest for energy trading when bundled together. The start-up works with Germany’s most renowned traders and puts them into competition with each other – for the first time ever. For customers, this means particularly high revenues and less risk.
TESVOLT Energy uses intelligent software developed in-house to control the battery storage systems in the pool so that they generate the greatest possible revenue with the least intensive operations.
Security plays an important part
“Ultimately, we no longer offer just a battery storage system, but a compelling investment together with TESVOLT Energy. Commerce and industry no longer even need to invest in PV installations; they just need a grid connection point with output of at least 50 kW and our new battery system,” reports Daniel Hannemann, Co-Founder and CEO of TESVOLT AG. Here, investment security is just as important as cybersecurity. “If you choose the trading option, we will give you a performance guarantee for 15 years at two cycles a day – that’s almost 11,000 guaranteed full cycles. The market standard is only 3,000 to 4,000 guaranteed full cycles. We can offer this because the intelligent software from TESVOLT Energy ensures that the storage system is operated for utmost profit, but with the least intensity. This makes the investment particularly safe,” continues Hannemann. Integrated smoke, heat and gas sensors, including an alarm and aerosol extinguishing system, also ensure maximum safety.
Exhibition stand at ees Europe
At ees Europe, Europe’s largest trade fair for batteries and energy storage systems, TESVOLT and TESVOLT Energy will be presenting the new TESVOLT Forton battery storage system and the highly profitable energy trading model at stand B2.110.

TESVOLT MARITIME spin-off presents milestone for clean shipping
PRESS RELEASE – Lutherstadt Wittenberg/Germany, 10.9.2024
//
Lutherstadt Wittenberg/Germany, 10.9.2024 – TESVOLT has announced a new joint venture, TESVOLT OCEAN. The TESVOLT Maritime Solutions division merged with Ocean Batteries from Norway last week. The innovation and market leader TESVOLT is focused on commercial and industrial energy storage solutions in Germany and Europe. Its new joint venture has developed a battery system that will enable significantly more ships in the maritime and inland shipping sector to be equipped with clean e-drives for the first time. Space in ships was often too tight for the compact battery storage systems available on the market, until now. The new “Kaptein Series” power storage system has the advantage that the battery modules can be installed individually anywhere in the ship – even on the floor. Due to its disruptive technology, the new power storage solution also features the highest energy density, the lightest weight, and the fastest charging capability on the market. This makes clean e-drives for shipping easier to implement as well as more cost-efficient.

Two maritime industry experts join forces
TESVOLT Maritime Solutions has supplied battery storage systems since 2018, primarily for workboats, deep-sea applications, and aquaculture, but also for pleasure craft and the yachting industry. TESVOLT Maritime Solutions has already equipped 160 ships with environmentally friendly battery propulsion systems, including the award-winning “E-Spatz,” a working vessel of the German Federal Waterways and Shipping Administration. Ocean Batteries has been offering modular, safe, and powerful battery solutions since 2019. TESVOLT holds a 51% stake in the joint venture TESVOLT OCEAN. TESVOLT OCEAN presented its new “Kaptein” battery storage system at SMM, the world’s leading maritime industry trade fair, last week in Hamburg.
Longest range and fastest charging
“We’re entering the market with a best-in-class storage system, offering a technological solution for the biggest pain points of ship owners, system integrators, and shipyards,” explained Kent Thoresen, CTO of TESVOLT OCEAN. “The range of ships with electric propulsion, for instance, is still a problem for many owners. Ship spaces are often cramped, so not enough battery modules can be accommodated to achieve the desired range. At 246 Wh per liter, our new Kaptein system has the highest energy density on the market to date, meaning despite its high capacity it takes up very little space.”
Most batteries approved for use in shipping did not even have a continuous C-rate of 2 C. At 4 C, the “Kaptein” storage system offers the highest continuous C-rate available in the maritime industry to date. This means significantly shorter charging times for ship owners.
Light, safe, and individually installable
The new storage system also scores highly in terms of weight. At just 4.83 kg per kWh of storage capacity, it will be the lightest battery system for shipping on the market; batteries currently available on the market weigh at least 7 kg per kWh. A unique fire suppression system ensures maximum safety.
“We spent three years speaking intensively with customers in six focus groups about what they need. That’s why Kaptein fits their needs so well. It solves real problems in e-propulsion for ships,” added Kilian Hoffmann, CCO at TESVOLT OCEAN. “We’ve already had a huge number of inquiries about the new battery system.”
Support right from the start
“Every customer has different goals. That’s why we always tailor our battery system precisely to the individual customer. Kaptein is not an off-the-shelf product. But due to its special cell-to-module design, it’s exceptionally cost-efficient compared to the rest of the market,” said Øystein Kjæreng, CEO von TESVOLT OCEAN. “We’re a one-stop shop, offering planning, installation, and commissioning as well as monitoring, maintenance, and recycling. We want to make a significant contribution with this new product toward accelerating the equipping of shipping with clean e-drives — as simply and cost-effectively as possible.”
