The SolBrid: Extra flexible new Steca inverter for up to 4 PV strings
PRESS RELEASE – Memmingen, 07.06.2023
//
With the new StecaGrid inverter SolBrid, Steca presents an exceptionally flexible and powerful three-phase 10 kW hybrid inverter. The SolBrid has up to four MPP trackers, which makes it suitable for photovoltaic installations on complex roof layouts. With a battery charging current of up to 25 A, it can be connected to a wide range of different high-voltage battery types. The inverter can be combined with the StecaGrid Switch to shift into stand-alone mode and supply a building with emergency power in the case of a blackout. That way the energy consumers in the house can seamlessly use power from the PV installation or a battery.
Future-proof, thanks to flexible PV input ports
“The SolBrid provides installers with a particularly flexible solution for a multitude of system variants, including complex roof layouts, different module and battery types, and standby power supply. The new inverter covers a wide range of applications,” says KATEK’s Dr. Peter Grabs.
Depending on the product variant, two or four MPP trackers enable a maximum photovoltaic input current of 15 Ampere each and an input voltage of up to 1,000 Volts. The first unit of the product range has an output of 10 kW.
App control and variable interfaces
Installation of the new inverter is possible via an app and users can access the operating data via mobile device. As a result of its IP65 standard housing, the inverter can also be installed outdoors.
A battery management system for BYD storage systems and an RS485 interface have been integrated (with further storage systems to be added). The RS485 enables the StecaGrid Switch circuit breaker and additional energy meters to be connected.
StecaGrid Switch for even more functions
Installing the StecaGrid Switch together with the SolBrid adds even more functions: The intelligent circuit breaker enables emergency power operation as well as real time measurement of energy consumption with deviation rate of just 2%, for accurate monitoring.

Tesvolt presents storage solutions for special safety requirements
PRESS RELEASE – Wittenberg, 30.05.2023
//
At this year’s smarter E Europe trade fair in Munich, Tesvolt has joined with Denios to present an all-in-one solution that combines a battery storage system and fire protection – the only one of its kind in the world. The Power Safe product line also meets the most stringent safety requirements in commercial and industrial settings, for example in operations located in water conservation areas or regions that are at a risk of forest fires, or as required by some insurers. Products in this line feature cases offering F90 fire resistance rating and are available in various sizes, from small-scale 80-kWh solutions to large energy storage systems with several megawatt hours.
Press images are available here: https://www.tesvolt.com/en/press/tesvolt-presents-storage-solutions-for-special-safety-requirements.html
Sophisticated fire protection case for extreme requirements
“For years now we have been engaged with the safe storage and handling of hazardous materials. Tesvolt not only has high-performance, durable storage systems, it also has some of the safest battery storage technologies on the market. However, in some cases, safety requirements are particularly strict, for example in countries with special environmental regulations or specific requirements from insurers,” explains Markus Boberg, Business Development Manager at Denios. “Now we have joined together to develop a technical solution that can meet the strictest safety requirements, by enclosing the battery storage system within an additional fire safety case.”
Proof of safety for public authorities
In the Power Safe product line, storage systems come in a spatial system with dual-frame construction classified as REI 90 or REI 120 fire protection. It can withstand fire, either internal or external, for at least 90 minutes, fulfilling the standards for safety certification demanded by approval authorities and greatly reducing complex approval processes. This safety certification also allows the system to be installed without a minimum clearance between it and adjacent buildings. Moreover, Denios offers round-the-clock remote monitoring and will alert the operator immediately in the event of a problem with the system. An aerosol-based extinguishing system is also available for the spatial system.
Certified safety
“Tesvolt storage systems already fulfil particularly stringent safety requirements. We have a multi-level safety concept and our storage systems are certified by the testing institute TÜV Rheinland. I am particularly pleased that we can now also offer our commercial customers a technical solution for highly sensitive environments. With this we have cleared yet another hurdle on the path to universal availability of clean energy,” says Simon Schandert, CTO and Co-Founder of Tesvolt.
The exceptionally high safety levels of Tesvolt storage systems are driven partly by the design of the battery cells: prismatic cells are considered to be the safest lithium-ion cells. At the system level, Tesvolt’s battery management system also monitors the voltage of each individual cell. This means the whole system is subject to constant plausibility monitoring. If the normalised range is exceeded, the system automatically switches to a safe state.
Power Safe spatial systems with fire protection come with European Technical Assessment (ETA) and associated CE labelling. This offers enhanced planning and legal security for country-specific approval processes.
Tesvolt at smarter E
Power Safe battery storage systems are primarily sold through Denios, but on request they can also be processed through Tesvolt.
At the ees / The smarter E Europe trade fair in Munich, Tesvolt is exhibiting the new Power Safe storage systems at stand B2 110 from 14 to 16 June.

Tesvolt Introduces New Battery Storage Systems for Commercial Use
PRESS RELEASE – Wittenberg, 15.03.2023:
Tesvolt presents its new generation of battery storage systems TS HV 30-80 E, offering even better options for variation and, for the first time, a 10-year guarantee for system and performance. The new products are optimised for the needs of commercial enterprises – from small bakeries to large manufacturing companies – and allow for exceptionally high levels of safety and durability. From system configuration and commissioning to after-sales support, installers have full digital access to all services.
Press picture find here tesvolt.com/en/press/tesvolt-introduces-new-battery-storage-systems-for-commercial-use.html
The new generation of storage systems consists of the TS HV 30 E, the TS HV 50 E, and the TS HV 80 E. The efficient high-voltage storage units are easily scalable. Combined, they achieve a total energy of up to 5 megawatt hours. The new three energy storage systems also incorporate advanced Tesvolt battery modules, each with 22 Samsung SDI cells of the latest generation. The high energy density of the battery cells makes these storage systems especially economical. New features include the Sunny Tripower Storage X three-phase battery inverter from SMA, which ensures even faster reaction and control times as well as a broad usable DC voltage range. And the energy storage systems can now be combined with two different energy management systems: the Basic or Pro model. Tesvolt offers a 10-year guarantee for system and performance with the new storage systems.
Future-proof business models by virtue of multi-use capability
“Our new generation of battery storage incorporates all the knowledge we have gained from almost a decade of experience in developing energy storage systems for commerce and industry,” explains Simon Schandert, CTO and Co-Founder at Tesvolt. The new storage systems can adapt even more effectively to the individual preferences of commercial enterprises. That goes for standard applications such as self-consumption optimisation and peak shaving or for multiple applications running in parallel. “The multi-use functions enabled by our energy management system offer enormous potential. Tesvolt customers can combine almost all applications as needed, such as optimising self-consumption with simultaneous control of generators and consumers. Or the forecast-based charging of electric vehicles with concurrent zero feed-in, to give another example. In this way, it will be possible to realise applications and business models in the future that may not even exist yet,” Schandert adds.
Smart charging station control
The Pro model of the energy manager allows the user to control and prioritise up to 25 charging points. For example, customers could be granted prioritised access to parking spaces over employees. Another example is the capability to configurate a charging point in such a way that it uses only green electricity from a photovoltaic system.
Certified safety
The three new storage units, just like the preceding Tesvolt systems, will be certified by TÜV Rheinland for functional safety, among other things, making them among the safest on the market. These exceptionally high safety levels are driven partly by the design of the battery cells: prismatic cells are considered to be the safest lithium-ion cells. At a system level, Tesvolt’s battery management system monitors the voltage of each individual cell. The whole system is therefore subject to constant plausibility monitoring. In case the normalised range is exceeded, the system automatically switches to a safe state.
It’s all digital
Tesvolt offers its installation partners all services digitally. The installer can plan the storage system project, configure the storage system, and order it all online in the Partner Portal. The storage system can also be commissioned digitally; thus, the installer can simply scan the components on-site using QR codes. In the Partner Portal, every step is explained with “How to” videos, and personal advice is also available via the hotline.
Effective immediately, installers can access training on the new storage systems at any time in the Partner Portal under tesvolt.com/en/partner/become-a-partner.html
Tesvolt will be presenting the new generation of storage systems at the smarter E Europe trade fair in Munich, Germany, from 14 to 16 June, at booth B2 110.

VARTA research bets on AI to achieve longer battery storage lifespan
PRESS RELEASE – Nördlingen, 20.02.2023:
Together with three renowned partners, German battery specialist VARTA is developing a battery management system based on machine learning and artificial intelligence (AI). The research project, entitled “Longer,” aims to map the typical operating modes of home storage systems and their effect on batteries more precisely than existing software. This will allow the use of available battery capacity to be optimized, while at the same time conserving the battery. The partners’ goal is to achieve a longer battery life, decrease the material input needed, and reduce CO2 emissions at a lower cost.
Pressebilder: https://sunbeam-communications.com/en/varta-research-bets-on-ai-to-achieve-longer-battery-storage-lifespan-2/
The company launches a joint project with the Fraunhofer Institute for Solar Energy Systems ISE, NOVUM engineering GmbH, and TWT GmbH Science & Innovation
Research Coordinator at VARTA Storage Benjamin Achzet explained: “Home battery storage systems, today, typically complete 200 to 300 full charge cycles per year and are used almost exclusively to store solar power. In the future, home storage will also be able to act as an ‘electricity trader,’ thus further reducing energy costs and actively relieving the power grid.”
This will require storage systems with higher cycle stability, however. The Longer research project, which will run until the end of 2025, is intended to help prepare storage systems for such new tasks. With VARTA Storage as its coordinator, the project also has support from Fraunhofer Institute for Solar Energy Systems, NOVUM engineering, and TWT Science & Innovation.
AI to model individual battery aging
How battery storage systems age depends heavily on the number and depth of charging cycles, but also on a variety of other factors, including charging and discharging power as well as ambient temperature. Because both the processes within the battery and user behavior are very complex, aging is difficult to estimate using conventional methods. It has to be examined on an individual basis.
Through the Longer project, VARTA is using AI, together with machine learning, to develop models of user behavior and battery aging. To this end, programs are being implemented on field test devices of the VARTA.wall home storage system.
A new generation of individualized battery management
The AI is expected not only precisely to analyze load profiles in buildings, but also to learn how the battery should best be discharged or charged in any given situation, in order to operate more efficiently over time. “In the field trial, the AI independently learns how a particular load profile affects the battery, its state-of-heath. Over time, it will be able to predict the state-of-health, then allowing for predictive control,” said Jens Haupt, NOVUM engineering battery aging specialist. Such AI-based battery management will thus be able to make optimal use of the battery’s capacity, while also maximizing its service life.
Simulation models of storage facilities will be used in the Longer research, too, to test and validate the AI-based operating strategy efficiently, in a targeted manner. “Efficient simulation methods – or digital twins – not only allow validation in reasonable time frames, but also the testing of borderline scenarios that are otherwise costly to realize in the laboratory,” explained Alejandro Cárdenas, simulation expert at TWT Science & Innovation.
Instead of following fixed rules, AI finds the best strategy for each use case. “Typical yield and consumption patterns are already known to the AI and it constantly refines them through machine learning. This way, each home gets its own customized energy and battery management. Depending on personal preferences, it maximizes self-consumption, minimizes CO2 emissions, or optimizes for profitability,” added Arne Groß, Fraunhofer ISE software expert.
Through the research, the AI is to be used in storage devices produced by VARTA, which intends to deploy the technology to continuously improve its batteries. The company’s ultimate stated goal is to be able to offer a storage device with a lifetime warranty.

aleo presents new premium panel for Swiss Solrif solar roof tiles
PRESS RELEASE – Prenzlau/Hedingen, 2.8.2022:
The premium panels in aleo’s new LEO series are also available as solar roof tiles. With LEO Sol, aleo is launching a high-performance half-cell panel. LEO Sol can be integrated into the roof surface using the Solrif in-roof photovoltaic mounting system from Ernst Schweizer AG. The glass-foil panel with black back sheet is larger and higher-yielding than its predecessors. When mounting with Solrif, the classic roof tile is replaced by the solar roof tile, creating a high-quality and homogenous appearance on the roof.
You can find a press image here: www.aleo-solar.com/newsitem/aleo-presents-new-premium-panel-for-swiss-solrif-solar-roof-tiles/
New efficiency class for proven system
The new monocrystalline premium panel LEO Sol with a size of 1,169 mm x 1,607 mm x 17 mm and a peak output of 345 W consists of 96 half cells. By using half-cells with 10 busbars, aleo minimises the series resistance and thus maximises the efficiency of its LEO premium panel. Instead of flat wire, thin, round wires are used so that more light hits the cells. The division of the cells and the closely spaced busbars also ensure that the panles last longer, as additional current paths are created.
With the Solrif in-roof PV mounting system from Ernst Schweizer, which has been tried and tested for over 20 years, LEO Sol is laid overlapping and tension-free on the pitched roof instead of being clamped. The solar roof tile is laid directly on the supporting battens just like conventional clay roof tiles. In addition to partial roofs, full roof coverings are also possible: Solrif blind modules offer design options for integrating corners and edges around chimneys, skylights or dormers homogeneously into the roof. Due to the free lower edge of the panels, the Solrif system is self-cleaning and requires virtually no maintenance.
Simple planning, comprehensive testing
The planning software Solar.Pro.Tool from Schweizer allows the system configuration with LEO Sol to be planned easily and, taking into account statics and electrics, safely. LEO Sol has been tested and certified as a hard roofing system for fire protection, is free of snail tracks and can withstand hailstones of up to 40 mm.
Solar aesthetics Made in Europe
With its uniform appearance, the solar roof tile Solrif is also suitable for use on listed buildings and for aesthetically demanding new construction and renovation projects. “As the global market leader in in-roof photovoltaic installation, we have particularly high demands on the performance and aesthetics of our solar roof tiles. Together with aleo and LEO Sol, we offer an in-roof PV solution that combines the latest technology with a chic look,” says Helge Hartwig, Sales Manager Solrif at Ernst Schweizer.
Quality as well as sustainability go hand in hand in the production of both system components: The premium panel LEO Sol is produced at aleo in Prenzlau using 100 percent renewable energy and comes with a product and performance guarantee of 25 years. Ernst Schweizer produces the Solrif mounting system with durable aluminium directly in Switzerland. Since the solar roof tile replaces the classic roof tile, both materials and work steps are saved during installation. And thanks to short transport routes within Europe, the LEO Sol-Solrif system combination causes fewer greenhouse emissions during delivery.
William Chen, CEO at aleo: “Our new LEO series is the most powerful that aleo has produced to date. The LEO Sol panel meets the high quality standards of the new series. The black back sheet completes the elegant look of the panel. Together with the Swiss mounting system Solrif, we are bringing a high-quality and sustainable in-roof photovoltaic solution `Made in Europe` to the market that is something to be proud of.”

PRESS RELEASE – Düsseldorf, 4.7.2022:
The H2UB, Europe’s hydrogen hub for start-ups, companies and research and decarbXpo, the trade fair for industrial decarbonisation and energy storage, have signed a partnership agreement. As a part of their cooperation, the partners are connecting young companies from the hydrogen sector with industrial users and leading industrial organisations.
Press graphic Download
Decarbonisation needs cross-industry cooperation
“decarbXpo’s cross-industry and cross-sectoral approach is an ideal match for the innovations happening in the hydrogen sector which theH2UB is supporting: It’s not just a few industries but almost all economic sectors can reduce their climate-relevant emissions by utilising hydrogen. Upstream and downstream processes within the hydrogen value chain, supply chains, and converting and expanding the existing infrastructure call for a strategic approach. This is the only way to supply all users with enough hydrogen at the right time, and to plan and implement the use of hydrogen in a business context. A common roadmap and an active exchange between all participants are essential, and start-ups play an important role”, says Uwe Kerkmann, CEO of H2UB.
Joint stand “Experience H2 Innovation with H2UB”
The H2UB will offer start-ups from the hydrogen sector a presentation and communication platform at decarbXpo. H2UB invites start-ups from the entire value chain – from production, storage and transport of hydrogen to its use in different industries and sectors – to apply for a space at the “Experience H2 Innovation with H2UB” joint stand. The H2UB is also active in the accompanying programme of decarbXpo.
“We offer start-ups from the hydrogen economy an excellent opportunity to present their innovations and ideas to an expert audience from different industries and business sectors, and thus to potential beta customers”, says Kerkmann.
decarbXpo takes advantage of Messe Düsseldorf’s industry network

Tesvolt wins leading innovation prize for SMEs again
PRESS RELEASE – Wittenberg/Germany, 27 June 2022:
The battery storage system manufacturer has been named “Innovator of the Year 2022” //
Tesvolt, manufacturer of energy storage systems for commerce and industry, has been named “Innovator of the Year” in the TOP 100 competition for the second time. It secured first place in its size category of 51 to 200 employees in this leading innovation contest for German small and medium-sized enterprises (SMEs). The 24-member expert panel was impressed by the outstanding climate of innovation and the innovative technology that underpins Tesvolt’s energy storage systems. The TOP 100 trophy was presented on Friday as part of the German SME Summit in Frankfurt am Main’s Jahrhunderthalle. This was the competition’s 29th instalment.

An agile organisation: everyone can be an innovator at Tesvolt
“I believe that innovations are revolutionary ideas that make our world a better place. With many countries now seeking to gain independence from Russian gas imports, innovation in the field of renewable energies is more important than ever before,” commented Daniel Hannemann, Co-Founder and CEO of Tesvolt. “Most of the time, innovations are the result of spontaneous ideas – and then you need the courage and the right environment to transform ideas into marketable products. Anyone can be an innovator at Tesvolt thanks to our agile organisational structure. I am tremendously proud of our joint effort in becoming Innovator of the Year again.”
Tesvolt opted to implement an agile organisational structure four years ago. Since then, it has dispensed with classic hierarchies. All employees receive comprehensive training on the methods of the agile organisational structure. “At Tesvolt, decisions are made in the team – in line with an agile principle that rapidly leads to results. This approach works exceptionally well,” reported Tjorven Niels Graßnick, Corporate Agile Coach at Tesvolt. “All employees have also received company shares, which also promotes a climate of innovation.”
Technological innovation saves electricity costs
Tesvolt’s innovative energy management system (EMS) was also a crucial factor in the panel naming the Wittenberg-based company Innovator of the Year once more. The EMS captures the energy flows of all consumers and producers and controls them as efficiently as possible. This allows to combine a range of applications, such as optimised self-consumption and intelligent peak shaving. Previously, operators had to choose one of the possible uses in advance. So the energy storage system adapts better to the individual requirements of commercial and industrial uses and thus saves even more electricity costs.
Scientific selection procedure
The TOP 100 innovation competition is based on a scientific selection procedure. Prof. Nikolaus Franke (one of the world’s leading innovation researchers, with 25 research awards to his name) and his team compared 436 SMEs based on more than 100 innovation indicators. They scrutinised the climate of innovation and the management team’s willingness to promote innovation, and the success of the resulting products on the market. The expert panel used this analysis to choose the winners. The panel is made up of experts from business, academia, the media and politics – including the likes of consultant Roland Berger and politician Gregor Gysi. The competition’s project partners are the Fraunhofer Society for the Advancement of Applied Research and the German Association for Small and Medium-Sized Businesses (BVMW).
“The competition was very strong again this year and it was impressive to see how innovative SMEs have dealt with the changes and challenges of our time. From the large amount of applicants, we determined the best“, said Prof. Nikolaus Franke, scientific director of the contest. The jury awarded Tesvolt the top grade of A+ in the four categories of Innovation Promoting Top Management, Innovation Climate, Innovative Processes & Organisation and External Orientation.

Peter Werner, General Manager Energy Storage Systems: „VARTA.wall stands for VARTA’s development and design expertise. This new storage device is based on the experience and technology commitment from 135 years of VARTA’s company history. It heralds a generation change in our stationary storage systems.“
High performance even in emergency power mode
VARTA.wall was developed in Germany, is produced in Europe and is the first high-voltage storage system from VARTA with a capacity of ten to 20 kilowatt hours. Depending on the inverter used, the power is between 5.24 kW and 10.4 kW. Up to five systems can be operated in parallel.
The storage system is capable of providing emergency power and can supply the entire house with electricity in the event of a grid failure. A boost function increases the discharge rate (C rate), which is 0.5 in continuous operation, to 0.75 for a short time. This enables the storage system to absorb peak loads, such as those that occur when electronic devices are started.
Extremely flexible and easy installation
Dominik Gluba, Head of Operations Energy Storage Systems: „During the development, the focus was on our specialist partners’ desire for flexible and simple installation. This starts with the inverter compatibility, continues with the modularity and also includes the innovative module design and connector system. This allows the storage system to be installed in under 30 minutes.“
VARTA.wall is compatible with various market-leading inverter brands, including the market leader SMA, which is also the launch partner of the new storage system, and Kostal. Further compatibilities are in preparation. Thanks to its modular design, the storage device is also suitable for a wide variety of system configurations. The VARTA connector system ensures that the system components do not have to be wired.
New product family for energy self-sufficient living
In the coming months, VARTA will be launching further devices and services for energy self-sufficient living. This will include a wall box and a separate electricity tariff. The company is thus establishing itself as a partner for all households that are promoting their own energy transition.
VARTA will be presenting its energy storage systems from 11th to 13th May at Smarter E Europe in Munich in Hall B1, Stand 210.
