TESVOLT GmbH

TESVOLT AG, founded in 2014 by Daniel Hannemann and Simon Schandert in Lutherstadt Wittenberg, is an innovative company specializing in the development and manufacturing of high-performance battery storage systems for commercial and industrial use.

TESVOLT produces battery storage systems based on prismatic lithium-ion cells from Samsung SDI. These systems are suitable for a wide range of applications, from optimizing self-consumption from photovoltaic systems to supporting electric charging stations and providing backup against power outages. The storage systems can be connected to all renewable energy producers such as solar, wind, water, biogas, and combined heat and power, both in low-voltage and high-voltage networks and both on-grid and off-grid[2][3][4].

The company is driven by the vision of making affordable energy accessible to everyone, everywhere. TESVOLT believes that energy means freedom – the freedom to create, develop, and explore, independent of fossil fuels, weather conditions, and political influences. The slogan "Free to go green" reflects the company's commitment to a sustainable and self-determined energy future[5].

TESVOLT is advancing the energy transition by developing and implementing innovative and sustainable energy storage solutions. The battery storage systems from TESVOLT are equipped with a patented and TÜV-certified Active Battery Optimizer, which significantly increases the lifespan of the battery cells and ensures optimal charging and discharging. This results in a lifespan of the storage systems of up to 30 years[1][2][4].

The company has also distinguished itself through various international projects, such as powering the Expo site in Astana or supporting a large water pumping project in Rwanda, which secures agricultural cultivation and feeds the population[1].

TESVOLT is characterized by an agile corporate culture that promotes flat hierarchies and active participation of all employees in the company's development. This enables the company to respond flexibly to market changes and implement innovations quickly. Proximity to universities and research institutions in Wittenberg and Berlin ensures a continuous availability of qualified personnel and supports the steady growth of the company[4].

TESVOLT has received numerous awards, including the German Founder’s Prize in the "Rising Star" category, the "TOP 100" Innovation Award, and the international award for rural electrification (ARE). These recognitions underscore the company's innovative strength and success[3][4].

With its strong partnership with companies like Samsung SDI and SMA Solar Technology, as well as its own gigafactory in Lutherstadt Wittenberg, the first of its kind in Europe, TESVOLT sets standards in the energy storage industry and drives the global energy transition forward.
