Renewable Energy, Optimally Utilized

August 23, 2024

The vision of TESVOLT plc is to store the electricity generated by wind, solar, and hydropower plants in a way that enables it to be continuously available. This is made possible thanks to the innovative battery storage systems developed and realized by the company. To wire their systems, TESVOLT relies on HELUKABEL cables, which adhere to all necessary standards and international approvals and ensure the reliable and efficient transmission of data.

With the expansion of new and renewable energy, sufficient production is not the only challenge. This energy also needs to be stored. Users will, naturally, want to use the electricity created from solar, wind, or hydropower, even when the specific sources aren’t exactly accessible. Battery storage systems offer a solution for this in photovoltaic plants. They collect the energy generated during the day, and then at night, the energy is made available for use. Users are thus able to optimize the efficiency of their plants, increase the proportion of their private consumption, minimize peak loads, and further reduce dependency on fossil fuels.

TESVOLT plc, which was founded in 2014, has achieved notable success in their endeavors with this promising technology. Based in Lutherstadt Wittenberg, they are a worldwide leader for technology and quality in energy services and storage in both commercial and industrial settings. With more than 250 employees, TESVOLT develops and produces battery storage systems that are used by craft businesses, farming operations, supermarkets, municipalities, energy providers, and in industrial settings. This young company has already received many awards, including the “German Start-Up Award”.

Versatility: Compatible with Various Energy Sources

The battery storage systems developed by TESVOLT are compatible with photovoltaic and wind power facilities, as well as hydro and thermal power plants, and can also be used to optimize conventional energy sources such as diesel generators. “The range of applications for our products is extremely wide,” explains Simon Schandert, co-founder and CTO of TESVOLT. “We have already successfully completed more than 5,000 projects around the globe, from fish farms in Norway to vacation resorts in the Caribbean.” With a portfolio containing diverse, modularly built storage models with capacities ranging from 10 kWh up to double-digit megawatt hours, they have a perfect solution for every application.

The seamless transmission of power and data is an essential component of every application. Each individual battery module is connected to another with cables, and the storage system to the power inverter, which converts the batteries’ direct current into network-compatible alternating current. “A high-performance battery management system is required to maintain maximum efficiency in the complex interplay between different components,” states Schandert. In this vein, TESVOLT has developed the Active Battery Optimizer (ABO) and the Dynamix Battery Optimizer (DBO), which optimally regulate and monitor the charging and discharging of the battery cells. “Through these, we can prolong the life spans of our systems and reduce their energy consumption,” the TESVOLT founder explains.

Quality that leaves an immediate impression

As with all built-in components, TESVOLT only uses the highest quality cables in their battery storage systems. This is, in the end, an extremely important factor in how well the systems operate. The power and data cables are, naturally, HELUKABEL cables. The decision to go with the connection technology specialists at HELUKABEL, of course, came down to the product catalog. “HELUKABEL had the cables with the exact specifications we needed in their portfolio, and the transparent presentation and selection immediately won us over,” remembers Schandert. “With their delivery capabilities and service, we’ve been satisfied HELUKABEL customers for almost ten years.”

Area sales manager Roland Eggers is an experienced point of contact with HELUKABEL for TESVOLT and provides advice and support in all things pertaining to electrical connection technology.

“One of the products we deliver to TESVOLT is our HELUDATA TRONIC 2464/300, which is a flexible data cable that can be used as both a signal and measurement cable in machine and plant construction,” says Eggers. “The construction of the conductor is based on AWG sizing and has both UL and CSA approvals. With this, the cable is suitable for use in storage facilities in the American market.” For an export-oriented company such as TESVOLT, this is an ideal solution, as they are no longer required to keep multiple cable types in stock.

Durable, safe, and flexible

With their robust PVC jacketing, these cables are resistant to many environmental conditions. At the same time, they are flexible enough to be able to be used in cramped assembly spaces. “They are also flame-retardant according to both European and American standards,” Schandert adds. “Another small detail that cannot be understated is that our systems must adhere to strict safety requirements.”

When it comes to power and data transmission, HELUKABEL products contribute significantly to the exceptional quality and intelligent features of TESVOLT battery storage systems, which continue to impress users around the world. “We are very happy to have such a reliable and competent supplier as HELUKABEL,” TESVOLT’s CTO concludes. “I’m convinced that the success of our products is directly tied to this cooperation.”
