Founded in 2016, Wattsun aims to make sustainable energy accessible anytime, anywhere. Our innovative products open up new possibilities for professionals in need of electricity at locations beyond the reach of the regular power grid. We provide solutions that are both user-friendly and environmentally friendly.
Wattsun pop-up power was officially established in 2016 by the current owners, Koen Olieslagers and Bart Hendriks. Olieslagers, an industrial product designer, conceived the initial concept a year earlier, with Hendriks joining in the summer of 2016 after completing his studies in commercial economics. The two had met during their time at the Hogeschool Arnhem Nijmegen (HAN) and decided to collaborate on Olieslagers’ idea.
As early as 2015, the first sketches of the Wattsun concept were put on paper, marking the pioneering work in the field of stackable battery systems. Olieslagers focused on aspects such as stacking, portability, and user-friendliness. Concurrently, research was conducted to identify the right battery for the system, considering factors such as energy density, cycles, weight, and reliability. This laid the foundation for the unique stackable battery system.
After completing their studies, Olieslagers and Hendriks immediately began developing, producing, and selling their first battery systems. This endeavor was made possible by an investment from InnoEnergy. In addition to attracting investors, the duo also gained attention from the market. Wattsun secured its first customer in 2017, and by 2018, the first forty Wattsun modules were produced.
In recent years, Wattsun has experienced significant growth. Firstly, we obtained a global patent for our battery systems. We have built and iterated on various prototypes, maintaining a commitment to continuous innovation. This process involves collaboration with customers and extensive field testing.
As of 2023, our market share has seen explosive growth. Our power stations are now recognized throughout the Netherlands and beyond. Wattsun has become indispensable, especially in the construction sector, event industry, and the film world. While making strides in Europe, our ambition is to make sustainable energy mobile and accessible worldwide.
The “Wattsun Headquarters” has also evolved into a serious scale-up, featuring a talented group of passionate professionals who share the mission of Olieslagers and Hendriks. We are set for rapid growth in the coming years, and talent is more than welcome.
As early as 2015, the first sketches of the Wattsun concept were put on paper, marking the very first designs in the field of stackable battery systems.
We obtained a global patent for our battery system. To achieve this, we built and further developed various prototypes, a practice we continue to this day. We remain dedicated to continuous innovation, collaborating closely with our customers.
From the United States to Belgium and from the Middle East to Scandinavia, our battery systems are now deployed in over 50 countries.
Wattsun’s headquarters are located on the Kleefse Waard Industrial Park in Arnhem. This is the most sustainable industrial estate in the Netherlands, a location that perfectly aligns with our mission and vision. Our products are designed and developed in the Netherlands, with production taking place both in the Netherlands and elsewhere in Europe. This allows Wattsun to keep the production chain as short and sustainable as possible.
We strive to work with suppliers and manufacturers from the region, ensuring short transport lines. We also contribute to local knowledge development and sharing. From the research phase to production, material selection to design, collaboration to transportation: we aim for sustainability in every step.
